Taking Cold Showers

Interesting idea. Maybe I'll try it. I fear, though, that it'll just end with me lying in bed for an extra twenty minutes every day, not wanting to get up and face the cold shower. Some say that willpower is like a muscle, and that the more you use it the more you develop it. On the other hand, maybe willpower is more like... a muscle, and if you use it too much on any given day then it just gets worn out. Will a cold shower before breakfast be followed by donuts for lunch?
- wccrawford 15y ago
  I have to agree. I have a nice morning routine that starts my day off right. If I tried to add intentional pain to that routine, it would not be a good thing. This might be something to do on the weekends, or afternoons, or something... But not my mornings.
- jasonshen 15y ago
  I taught a course on the Psychology of Personal Change in college and there are papers that suggest that willpower resembles a muscle - in that it can degrade over time. But there are also other studies that suggest it can also be built up over time - like a muscle. Would you say that doing pushups in the morning is a bad thing? Yes, you're more tired later in the day, but if you keep doing it, you'll get stronger and stronger.
  - hugh3 15y ago
    Yep. Of course there's no particular reason to think that the muscle analogy needs to be accurate either way, though.

        Hmm, it seems like the research is pretty thin at present. I'm going to file this under "slightly more likely to be true than not" until I see more information.

  I am not a psychologist, but I've seen some interesting articles on how self-control is a semi-finite resource. The article linked to below was particularly interesting, as it even had a mechanism. Specifically, the participants' self-control was lowered when their glucose level was low and their glucose level dropped when they used their self-control http://psycnet.apa.org/journals/psp/92/2/325/ http://psycnet.apa.org/journals/psp/92/2/325/ Thus, the cold shower might not just be followed with donuts for lunch, but the lunch donuts may be necessary to skip having heroin for dinner. To re-iterate, I'm not a psychologist, so take all of this with a grain of salt.

Sounds a lot like Kneipp's idea (http://en.wikipedia.org/wiki/Kneipp http://en.wikipedia.org/wiki/Kneipp - was pretty popular in Germany when I grew up). Having been forced to take a week of cold showers due to a malfunctioning heater I can't say it made me any stronger. It just made me feel pissed off and not properly clean.
- bgutierrez 15y ago
  Jason Shen said that voluntarily taking cold showers increased his discipline. Can you imagine a different experience if you chose cold showers instead of being forced to take them? I don't feel like I've properly had a shower unless the shower has raised my core temperature, but I'm going to give this a try. The easiest life hacks are ones that don't require a time commitment and only minor changes in routine.
  - zacharycohn 15y ago
    Taking a cold shower lowers your body temperature, then your hypothalamus kicks in to compensate. You get out of your cold shower, and your body heats up. If you take a warm shower, you end up cooling down after the shower.
    - jrockway 15y ago
      Not my experience. Sometimes I take a cold bath (ice is involved) after running. With enough ice, I feel quite cold for many hours after getting out -- to the point where I get out an extra down comforter to sleep with, and am still cold.
      - tommi 15y ago
        That means you have lowered your core temperature and your body is simply unable to respond to that coldness quickly. It's vital that you feel cold at that point. Quick cold showers are just "tricking" your body.

I have a normal warm/hot shower to actually wash, and then at the end I switch off the heat and have a cold shower for a minute or two. I definitely feel the better for it afterwards, although the effect wears off after half an hour or so. The only problem is that in the summer, the `cold' water isn't actually very cold.

First there was Rejection Therapy and now this. I'm sure there's merit to this stuff but how many of these practices can one adopt before they transition from conqueror to masochist?
- jasonshen 15y ago
  Fair question. I don't intend to come off as masochistic but I can understand if it appears this way. I'm just sharing something I've found to add value to my life and suggesting that others try it and see if it also gives them value.

I'll be the meta-contrarian (http://lesswrong.com/lw/2pv/intellectual_hipsters_and_metacontrarianism/ http://lesswrong.com/lw/2pv/intellectual_hipsters_and_metaco...) and disagree. If you believe that it's important to deliberately suffer to build character, at least do something that provides some benefit like vigorous exercise, or even rejection therapy.
- jasonshen 15y ago
  Good point - if cold showers were the only thing you were doing to build self-discipline, that would be rather silly. I already work out almost everyday, put myself in uncomfortable social situations and other "character-building" activities. This is just one more thing I've added to the mix and that I'm sharing my thoughts on.
- influx 15y ago
  Talk about first world problems, it's almost embarrassing that you have to seek out discomfort and the only way to do it is to take a cold shower.

I've been ending my showers with cold water forever, but that's just because it's good for your hair (I have a lot of hair). I have not experienced any other appreciable benefits.
cadalac 15y ago
Funny, I started taking cold showers about a month ago, without having read any article about it. I guess because I was feeling unhappy for some time and I was annoyed from having so much comfort, like good food and warm water around me and not being happy, so I decided to ditch hot water. At first I used pure cold water (this was still the tale end of winter, so it would actually numb my skin) and managed to keep it up for about a week. After that my bad mood past, however I decided to keep up taking cold showers at a moderately cold temperature (still cold so you shiver and shrink but not so that it numbs your skin. So in conclusion I'll mention my results after a month. First of all, I feel good about it, and I never intend to go back to warm indulgent water. I feel like I got rid of an unnecessary comfort, second after about two weeks I felt like going back to warm water but the power of habit had already kicked in so I stayed with cold water. Third, Like mentioned in the article, the panic response to cold water is gradually going away, and soon I'll probably notice it flow into other areas in my life. So I think It's a quick and effective way to develop discipline and even self esteem. I would recommend this habit especially to high school kids who bear the brunt of mass marketing from large corporations selling useless products.

  Would you like to share some specific reasons why people shouldn't engage in cold showers? Or are you just going to make a personal attack that doesn't relate to anything I said?
  - jrockway 15y ago
    Would you like to share some specific reasons why people shouldn't engage in cold showers? Would you like to share some sort of science proving that taking a cold shower has some health benefit over talking a hot shower?
    - icegreentea 15y ago
      Well, not exactly what this is talking about, but after serious exercise, cold showers are better than hot showers for recovery purposes. Same reason applying ice works to reduce inflammation. It's basically a milder form of an ice bath. That said, taking cold showers and bragging about is kinda... dunno. In my mind, cold showers are something to be paired with other physical discomforts (like beating your body up to the point where the physiological benefits of a cold shower actually matter), not something to just do for the sake of doing. It's kinda like discipline gravy. Wonderful along with something, but disgusting by itself. But this is coming from an athletic background. I guess whatever makes you feel like a boss, makes you feel like a boss.
      - jasonshen 15y ago
        That's interesting. I didn't think about cold showers as a way to reduce inflammation but it's possible that the cold water acts as a mild anti-inflammatory. I was a gymnast for 16 years but alas my "beat the crap out of myself" days are over for now and I don't need to multiple parts of my body before walking out of the gym. I guess part of the reason why I like cold showers is that I miss the opportunity to struggle with and overcome strong feelings of discomfort.
fmavituna 15y ago
What will happen when cold shower feels as good as hot shower, will you start sit on ice all day, find new ways to suffer to "grow stronger"? Cold water itself might be healthier or not but without data, this practice sounds pointless and if we generalise the idea and boil down to suffering to grow stronger it sounds down right ridiculous.
ebiester 15y ago
Alternatively, take 20 seconds to wet yourself with water. fill a small bucket. Turn off water until the final minute when you wash off. You don't have to keep the water running to stay cold, and you can save a bit of water in the process.
georgieporgie 15y ago
Good luck getting a clean shave under those conditions. It sometimes amazes me what people think constitutes adversarial conditions, and testing oneself. Reaching down and turning a knob, then telling yourself that you're building character? Odd. By the way, I loved the comments. They read like something I would have written as a twelve year old. "I'm like a Navy SEAL because I beat myself up every day with a cold shower! I'm tough!" My favorite is paleo guy: But I also do it due to the paleo/primal lifestyle I’ve been adopting—the fact that we didn’t evolve bathing with the convenience of hot coals or temperature faucets and and that our bodies are probably designed to buck up and shower in less-than-ideal conditions. Except that you'll find that frequency of bathing, and bathing as a social and relaxation mechanism, directly correlates with availability of hot water. Where there are hot springs, there are happy, relaxed locals.

  >our bodies are probably designed to buck up and shower in less-than-ideal conditions. By this argument, our bodies are designed to die of smallpox.
  - bennesvig 15y ago
    Yes, of course there are exceptions to every generality. Man also isn't conditioned to sit at a desk for 8 hours a day or eat highly processed foods on a consistent basis. This doesn't disprove his point that exposing yourself to a little bit of the natural environment is probably a good thing.
    - natural219 15y ago
      What? That completely disproves his point that "exposing yourself to nature is probably a good thing." You can't cherry-pick which types of nature you should expose yourself to -- you have to supply some other criteria.

The way I see it, learning to be uncomfortable is beside the point; it's about finding the positives, not ignoring the negatives. If you learn to be uncomfortable, you become complacent, and don't do things to improve your life in real, tangible ways, like, say, negotiating a better salary. If there's a problem you need to solve with a method like this, that's great, but I would hesitate to recommend that people regularly incorporate unpleasant things into their daily life for the sole sake of them being unpleasant. That ultimately leaves you with less understanding of not only how to lead a pleasant life but also of how to improve the lives of the people around you, this latter goal being the core of entrepreneurship. E.g. if you try to use nothing but `cat` to edit files, you will never design a better text editor. If you walk to work, you won't be able to contribute to advances in vehicle technology. Ultimately I think our goal as humans is to reduce that sort of thing, not to increase it; otherwise we might as well revert to nomadic tribalism. To quote Edward Abbey: One final paragraph of advice: do not burn yourselves out. Be as I am — a reluctant enthusiast... a part-time crusader, a half-hearted fanatic. Save the other half of yourselves and your lives for pleasure and adventure. It is not enough to fight for the land; it is even more important to enjoy it. While you can. While it’s still here. So get out there and hunt and fish and mess around with your friends, ramble out yonder and explore the forests, climb the mountains, bag the peaks, run the rivers, breathe deep of that yet sweet and lucid air, sit quietly for a while and contemplate the precious stillness, the lovely, mysterious, and awesome space. Enjoy yourselves, keep your brain in your head and your head firmly attached to the body, the body active and alive, and I promise you this much; I promise you this one sweet victory over our enemies, over those desk-bound men and women with their hearts in a safe deposit box, and their eyes hypnotized by desk calculators. I promise you this; You will outlive the bastards.
- Derbasti 15y ago
  I agree with you, except for > If you walk to work, you won't be able to contribute to advances in vehicle technology. Are you implying that walking to work is an 'uncomfortable' thing like taking a cold shower? I may be misunderstanding you there, but I , for one, hate sitting in a car and suffering through morning-hour traffic jams. I hate searching for a parking spot. I much rather take my bike to work. You know, not to work out, but to breathe fresh morning air for once. To enjoy the sound of birds. Riding your bike, or walking, is exactly what that nice quite of yours is recommending. You can advance your vehicle technology as far as you like, but if that vehicle will be used for a distance that you could easily walk, it will never be effort well spent.
rudiger 15y ago
Every time I take a cold shower, I get a raging boner. Is there any physical basis for this, or is it a purely a mental thing?
- tommi 15y ago
  Increased blood circulation in response to the cold could be a factor.

jarin 15y ago
I don't know, I've tried turning the water icy cold for the last few minutes of the shower (based on an Art of Manliness article), and it seems like trying to artificially create meaning in something very trivial. I think there's value in changing things up so you don't get too comfortable, but to me this is about as meaningful or important as changing which brand of deodorant you use. Instead, I'd recommend things like going to see a play, listening to a new genre of music, taking cooking classes, etc.
jasonwilk 15y ago
I consistently take cold showers, and I actually really enjoy it. Has nothing to do with being tough. I just happen to feel a lot more awake post-shower, it's a lot more satisfying to dry off after (and when you get out of the shower, you aren't as cold), my skin feels better and Im quite possibly in a better mood. Also, if I have had a few drinks the night before, a cold shower is far superior than a hot shower.
- bilban 15y ago
  I agree, I take cold showers because I enjoy them - they are far from torture! I think the bloke that wrote the article totally missed that. In winter I even take a cold shower - and always feel far warmer after - even if the water is like ice. I run hot showers occasionally too. Though I never have any compulsion to leave the shower, I just want to stand there. The other thing is it never feels hot enough! Try it, just start with cold. You might even like it.

I've tried this twice in my life in the US. Both times I came down with fever. In India, you really want cold showers during the summer.

  Indeed, it depends on the weather. When it's warm summer weather here, I take lukewarm showers. When I was in Italy, I took cold showers. What a relief!
joeyh 15y ago
Coincidentially I had just taken a cold shower before reading this. But then, it's 95 degrees out; it's 75 with high humidity in the earth-sheltered house, and in these conditions a spring-fed shower is very welcome. I'll bet this guy is going from an aggressively airconditioned room to a cold shower. No wonder it's unpleasant.
khafra 15y ago
I wish I could take cold showers. Here in Florida, the water doesn't get much below 80 degrees unless you add ice.

Taking a cold shower _because_ it's unpleasant makes as much sense as cutting yourself.

  Except for the physical scarring and potential for infection.

    Why is physical scarring bad? Why is infection bad? Humans dislike infection for the same reason they dislike cold showers. Pain is bad. Avoiding pain is good.

Tim Ferris talks about cold showers a lot in his 4 hour body book. Lately i've been 1) avoiding masturbation and 2) taking a hot shower followed immediately by full cold. I feel like I have more energy throughout the day, I'm more aggressive, and more confident. I've also started to eat brazil nuts. Cold showers (cold in general) stimulate fat loss. I always feel amazing after getting out of the cold too... like the wind was just completely knocked out of me. Almost like a high. Here are some resource, but again, it's a major theme in the 4-hour body book. http://www.stevepavlina.com/forums/health-fitness/58335-cold-showers.html http://www.stevepavlina.com/forums/health-fitness/58335-cold... http://www.lisajohnsonfitness.com/the-4-hour-body-thoughts-on-the-first-week/ http://www.lisajohnsonfitness.com/the-4-hour-body-thoughts-o...

You're doing a reverse of the James Bond shower, which has you start warm and then turn to cold at the end.
mattdeboard 15y ago
As someone who has taken many, many, many cold showers in Iraq and other unpleasant locales, if your character is so underdeveloped that taking a cold shower builds it up, you should be taking bigger strides. Edit: point being, cold showers are such an unbelievably mild form of suffering that suggesting they're "character builders" is painfully pretentious. Surprised this blogger of all people wrote this. He knows suffering.
- jasonshen 15y ago
  Hey Matt - thanks for your thoughts. I think mild is definitely in the eye of the beholder. Doing 50 pushups everyday would be a walk in the park for me - it might be absolute hell for someone else. A developer/designer might take 15 seconds to debug something that I could only manage after hours if not days of researching/Googling/struggling. As I mentioned in the post - I really like warm showers and hate being cold. For me, it really was quite difficult to force myself to take a cold shower. It's now much easier. You're right, I have gone through intense suffering - dislocating your knee, tearing all 4 ligaments and undergoing 5 surgeries will do that to you. So please have faith in me when I say that this activity was a challenge for me, was highly uncomfortable at first and required substantial willpower. I offer my experience as something others can draw from and suggest that this might be worth doing.
  - Psyonic 15y ago
    I've been ending at least 80% of my showers with a minute or two of cold water since getting the 4 hour body a few months ago. It was definitely hard at first, then got easier, then got somewhat hard again (started to seem pointlessly masochistic), but all in all I feel it's been worthwhile.
- tygorius 15y ago
  suggesting they're "character builders" is painfully pretentious. No, it's just clear that the author has a wider understanding of the issue (and more compassion) than you display. It's like criticizing people for only being able to do a couple of pushups when they first visit the gym. The fact that they keep going to the gym and working at building strength is the important part, not how many repetitions they start out with. Recently deceased Aikido master Koichi Tohei[1] was a sickly child and had to take a year off from high school because he had pleurisy. Being forbidden to exercise, he started improving his character where he could: getting out of bed quickly and bathing by dumping buckets of cold water on himself.[2] He would later wind up leading troops in battle, so he hardly strikes me as a wimp. But since he would later stress that simple beginning exercise in some of his writings, just maybe he and the blogger aren't so "painfully pretentious" as you think.

There was a study I read about where a large group of people where divided into 2 equal groups. The non-control group was had their body temperature lowered. The study showed those with a lowered body temperature got sick more frequently. I googled to try and find a reference, but couldn't locate it. So, on the cold showers thing... no thanks.

I live by the beach, and every morning I get up and surf for 30 minutes to 1 hour. Getting in a hot shower after that is AMAZING, especially during the winter months. Would highly recommend over a forced cold shower.
radagaisus 15y ago
I've been in the army. I've taken cold showers every day. Our commanders woke us up in 2am for a long run while carrying a rubber boat filled with water to the beach almost every day. When we finally got to the beach, we had to do push ups with our head inside the freezing water. I ran 20km carrying a fat man on a stretcher, cursing him under what remained of my breath. Guess what? I still read HN instead of getting shit done. Tolerance is only built on the same vector.
- Psyonic 15y ago
  Wow... interesting. For some reason I would have expected that discipline to carry over. How long were you in the army? I'd be interested in asking you a few questions if you're up for it.
BasDirks 15y ago
Suffering is completely the wrong concept when one is considering the benefits of a cold shower. The biggest plus of a cold shower is the shock-effect that makes you alert and awake.

Cold showers just make me feel great. Never suffered of those. I also use them after workouts, as described here: http://paleohacks.com/questions/995/what-is-the-deal-with-cold-showers/1019#1019 http://paleohacks.com/questions/995/what-is-the-deal-with-co... "Invented by the French and used by virtually every elite athlete on the planet, it is often confused with some kind of torture. Right after working out, hop into the shower. First, cook yourself for no longer than 5 minutes in hot water, relax, get those blood vessels well dilated. Then slowly add cold water to the mix until it's so cold you can't stand it. Endure it. Focus the water on the back of your head and the muscles you just worked. Feel the blood vessels constrict. Stay under it for as long as it takes to really cool off - 2 to 3 minutes. The time it takes to cool down will increase as you adapt, and the temperature for cooling will decrease. Then, switch the hot water back on. The blood vessels will dilate, and inrushing blood will flush the lactic acid out. Start the cooking process again. Repeat at least two cycles and finish on cold. This induces a tonic effect and you'll rebound, flushing again as your body warms up in your clothes."

My dad used to tell me about the time he was in a cold, remote location (military), and he was the only one in their group who would take cold baths (from a snow-fed stream nearby); the others would warm up water and then bathe. The entire year he was there, he never fell ill; though the rest of the bunch came down with cold/flu with regularity. I know this is not scientific evidence, but just anecdotal. Thanks for the article; I had forgotten about his story, and now will try to work in cold showers slowly.

I've done cold showers at times (for medical reasons). I loathe them and only take them in desperation. Trivia that the HN crowd is unlikely to know: Ending showers with a brief bit of cold water is supposedly something French women do to keep themselves perky.

The ability to discipline yourself with nothing but the power of your mind is one of the single greatest skills a human can have. Put the ice cream cone down, and pick up a book, then go to the gym then finish up that big project you started 3 months ago. It is the art of taking control of your own body even though it hurts. It's what separates kings from bums lying around on the side of the road.
- araneae 15y ago
  Sure. It's great. So why waste it taking cold showers? This article is so completely pointless it makes my head spin.
- raffaelc 15y ago
  "It's what separates kings from bums lying around on the side of the road." Since kingship is, by definition, hereditary, I'm pretty sure that what separates kings from bums is largely a mere accident of birth. Just as we have evolved with an unrealistic perceptual bias to see lions in forest shadows - thinking you see one where there isn't one is low cost, failing to see one when there is one is a potentially lineage-ending move - we've also evolved to think that we have much more influence on the course of our lives than we do. We have limited self control; our conscious minds can really only inhibit unconscious impulses, and that only to a limited extent. Nevertheless, we've evolved to believe that we have much greater control than we do so that we continue to try to exercise the limited control that we do have, rather than not trying at all because we see our distinctly limited self control for what it is.
Aga 15y ago
A lot of commenters suggest to do something else instead of taking cold showers. I don't see the need to trade cold showers with anything as you certainly are able to e.g. lift weights AND take cold showers! Why not get the benefits of both? If nothing else, taking cold showers at least prepares you to having a swim in cold water (in a hole in the frozen sea) while attending sauna during winter time in Finland.. :-)

It needn't be a shower. Meditation, yoga, and some forms of martial art work just this way. Each of them trains you to accept discomfort without reacting to it. There's a Buddhist story where a student asks a teacher about the secret of correct practice. The answer: "Don't move." Meditation hurts. A lot. Your legs ache and often fall asleep, your lower back gets stiff. But you're not supposed to move. Over time you do become more flexible, but more importantly you learn to accept the pain without needing to fix it. It turns out that if you can focus on the moment, the pain isn't so bad - it's actually the fear of the pain lasting into the future that causes you stress. As Shunryu Suzuki (founder of SF Zen Center) said: "Don't move. Just die over and over. Don't anticipate. Nothing can save you now because you have only this moment." But there's nothing uniquely buddhist about this... My Berkeley tai chi instructor loves to have students hold postures for extended periods to the same effect. You move past this point where you think you're going to collapse and suddenly find a way to relax further into the form. And any serious yoga student will tell you that holding yoga poses for them accomplishes the same thing. Sounds like the cold shower had a similar effect for Jason. It's not macho, magical, or new agey - it's just a practice - though one that may seem odd in our can-do, fix-it-now culture. As we grow we learn that not every problem can be fixed, and devoting time to practices like these can teach you to be okay with that.

I applaud the general concept here but I think you're doing yourself a disservice if this is the extent to which you take this. Go take up rock climbing (toproping in a gym doesn't count), whitewater kayaking, or some other activity that will get you outdoors doing something involving real risk assessment and nontrivial consequences. If you're anything like me you'll find your attention to detail increases dramatically. Your ability to shrug off daily stresses will also increase. Compared to being gripped out of your mind 120 feet off the ground it's pretty hard to take some guy cutting you off in traffic seriously. Whatever you do, keep pushing your boundaries. Good luck!

The idea upon which this is based is called hormesis. See: http://en.wikipedia.org/wiki/Hormesis http://en.wikipedia.org/wiki/Hormesis http://en.wikipedia.org/wiki/Radiation_hormesis http://en.wikipedia.org/wiki/Radiation_hormesis http://en.wikipedia.org/wiki/Caloric_restriction http://en.wikipedia.org/wiki/Caloric_restriction The basic idea is that our ancestors were under stress so often that we evolved beneficial processes that kick in during times of stress, and only times of stress. Without the right environmental cues our bodies won't do the right thing. Imagine having to red-line your car for a few seconds in order to start the automatic oil-change.

Hilarious! Anyone read the Wikipedia article about "The Junction Boys", a college football team that Bear Bryant took to the town of Junction, Texas in the middle of summer? He made them do grueling practice in the blazing heat, and withheld water in order to toughen them up. At the end of this brutal regimen, the players who were left went on to... continue to suck and lose almost every game in the season.

I frequently take cold showers between sauna sessions. Both are extremes, in the sauna I like the feeling of hot steam making my skin shiver just after a splash of water on the heater. In a cold shower I like the initial gasp for air and the shiver down my spine before I get used to it. I do remember reading something about intensive chilling would improve my immune defense, but that just made me start doing this. Now I do it because it feels good to have some ice cool water after 10 minutes in the sauna giving you a slight fever.
michaeldhopkins 15y ago
For about four months in 2007 I took cold showers. Over time I found I was touching the water less and less and was developing hygiene problems. Additionally, I was taking longer and longer to jump in so the time savings were eroding. So, I stopped. To this day I do prefer less warm water than I did before the experiment, though.

Interesting idea. Maybe I'll try it. I fear, though, that it'll just end with me lying in bed for an extra twenty minutes every day, not wanting to get up and face the cold shower. Some say that willpower is like a muscle, and that the more you use it the more you develop it. On the other hand, maybe willpower is more like... a muscle, and if you use it too much on any given day then it just gets worn out. Will a cold shower before breakfast be followed by donuts for lunch?

wccrawford 15y ago
I have to agree. I have a nice morning routine that starts my day off right. If I tried to add intentional pain to that routine, it would not be a good thing. This might be something to do on the weekends, or afternoons, or something... But not my mornings.
jasonshen 15y ago
I taught a course on the Psychology of Personal Change in college and there are papers that suggest that willpower resembles a muscle - in that it can degrade over time. But there are also other studies that suggest it can also be built up over time - like a muscle. Would you say that doing pushups in the morning is a bad thing? Yes, you're more tired later in the day, but if you keep doing it, you'll get stronger and stronger.
- hugh3 15y ago
  Yep. Of course there's no particular reason to think that the muscle analogy needs to be accurate either way, though.

I am not a psychologist, but I've seen some interesting articles on how self-control is a semi-finite resource. The article linked to below was particularly interesting, as it even had a mechanism. Specifically, the participants' self-control was lowered when their glucose level was low and their glucose level dropped when they used their self-control http://psycnet.apa.org/journals/psp/92/2/325/ http://psycnet.apa.org/journals/psp/92/2/325/ Thus, the cold shower might not just be followed with donuts for lunch, but the lunch donuts may be necessary to skip having heroin for dinner. To re-iterate, I'm not a psychologist, so take all of this with a grain of salt.

Sounds a lot like Kneipp's idea (http://en.wikipedia.org/wiki/Kneipp http://en.wikipedia.org/wiki/Kneipp - was pretty popular in Germany when I grew up). Having been forced to take a week of cold showers due to a malfunctioning heater I can't say it made me any stronger. It just made me feel pissed off and not properly clean.

bgutierrez 15y ago
Jason Shen said that voluntarily taking cold showers increased his discipline. Can you imagine a different experience if you chose cold showers instead of being forced to take them? I don't feel like I've properly had a shower unless the shower has raised my core temperature, but I'm going to give this a try. The easiest life hacks are ones that don't require a time commitment and only minor changes in routine.
- zacharycohn 15y ago
  Taking a cold shower lowers your body temperature, then your hypothalamus kicks in to compensate. You get out of your cold shower, and your body heats up. If you take a warm shower, you end up cooling down after the shower.
  - jrockway 15y ago
    Not my experience. Sometimes I take a cold bath (ice is involved) after running. With enough ice, I feel quite cold for many hours after getting out -- to the point where I get out an extra down comforter to sleep with, and am still cold.
    - tommi 15y ago
      That means you have lowered your core temperature and your body is simply unable to respond to that coldness quickly. It's vital that you feel cold at that point. Quick cold showers are just "tricking" your body.

I have a normal warm/hot shower to actually wash, and then at the end I switch off the heat and have a cold shower for a minute or two. I definitely feel the better for it afterwards, although the effect wears off after half an hour or so. The only problem is that in the summer, the `cold' water isn't actually very cold.

First there was Rejection Therapy and now this. I'm sure there's merit to this stuff but how many of these practices can one adopt before they transition from conqueror to masochist?

Fair question. I don't intend to come off as masochistic but I can understand if it appears this way. I'm just sharing something I've found to add value to my life and suggesting that others try it and see if it also gives them value.

I'll be the meta-contrarian (http://lesswrong.com/lw/2pv/intellectual_hipsters_and_metacontrarianism/ http://lesswrong.com/lw/2pv/intellectual_hipsters_and_metaco...) and disagree. If you believe that it's important to deliberately suffer to build character, at least do something that provides some benefit like vigorous exercise, or even rejection therapy.

jasonshen 15y ago
Good point - if cold showers were the only thing you were doing to build self-discipline, that would be rather silly. I already work out almost everyday, put myself in uncomfortable social situations and other "character-building" activities. This is just one more thing I've added to the mix and that I'm sharing my thoughts on.

I've been ending my showers with cold water forever, but that's just because it's good for your hair (I have a lot of hair). I have not experienced any other appreciable benefits.

cadalac 15y ago

Funny, I started taking cold showers about a month ago, without having read any article about it. I guess because I was feeling unhappy for some time and I was annoyed from having so much comfort, like good food and warm water around me and not being happy, so I decided to ditch hot water. At first I used pure cold water (this was still the tale end of winter, so it would actually numb my skin) and managed to keep it up for about a week. After that my bad mood past, however I decided to keep up taking cold showers at a moderately cold temperature (still cold so you shiver and shrink but not so that it numbs your skin. So in conclusion I'll mention my results after a month. First of all, I feel good about it, and I never intend to go back to warm indulgent water. I feel like I got rid of an unnecessary comfort, second after about two weeks I felt like going back to warm water but the power of habit had already kicked in so I stayed with cold water. Third, Like mentioned in the article, the panic response to cold water is gradually going away, and soon I'll probably notice it flow into other areas in my life. So I think It's a quick and effective way to develop discipline and even self esteem. I would recommend this habit especially to high school kids who bear the brunt of mass marketing from large corporations selling useless products.

  - icegreentea 15y ago
    Well, not exactly what this is talking about, but after serious exercise, cold showers are better than hot showers for recovery purposes. Same reason applying ice works to reduce inflammation. It's basically a milder form of an ice bath. That said, taking cold showers and bragging about is kinda... dunno. In my mind, cold showers are something to be paired with other physical discomforts (like beating your body up to the point where the physiological benefits of a cold shower actually matter), not something to just do for the sake of doing. It's kinda like discipline gravy. Wonderful along with something, but disgusting by itself. But this is coming from an athletic background. I guess whatever makes you feel like a boss, makes you feel like a boss.
    - jasonshen 15y ago
      That's interesting. I didn't think about cold showers as a way to reduce inflammation but it's possible that the cold water acts as a mild anti-inflammatory. I was a gymnast for 16 years but alas my "beat the crap out of myself" days are over for now and I don't need to multiple parts of my body before walking out of the gym. I guess part of the reason why I like cold showers is that I miss the opportunity to struggle with and overcome strong feelings of discomfort.

fmavituna 15y ago

What will happen when cold shower feels as good as hot shower, will you start sit on ice all day, find new ways to suffer to "grow stronger"? Cold water itself might be healthier or not but without data, this practice sounds pointless and if we generalise the idea and boil down to suffering to grow stronger it sounds down right ridiculous.

ebiester 15y ago

Alternatively, take 20 seconds to wet yourself with water. fill a small bucket. Turn off water until the final minute when you wash off. You don't have to keep the water running to stay cold, and you can save a bit of water in the process.

georgieporgie 15y ago

Good luck getting a clean shave under those conditions. It sometimes amazes me what people think constitutes adversarial conditions, and testing oneself. Reaching down and turning a knob, then telling yourself that you're building character? Odd. By the way, I loved the comments. They read like something I would have written as a twelve year old. "I'm like a Navy SEAL because I beat myself up every day with a cold shower! I'm tough!" My favorite is paleo guy: But I also do it due to the paleo/primal lifestyle I’ve been adopting—the fact that we didn’t evolve bathing with the convenience of hot coals or temperature faucets and and that our bodies are probably designed to buck up and shower in less-than-ideal conditions. Except that you'll find that frequency of bathing, and bathing as a social and relaxation mechanism, directly correlates with availability of hot water. Where there are hot springs, there are happy, relaxed locals.

  Yes, of course there are exceptions to every generality. Man also isn't conditioned to sit at a desk for 8 hours a day or eat highly processed foods on a consistent basis. This doesn't disprove his point that exposing yourself to a little bit of the natural environment is probably a good thing.

The way I see it, learning to be uncomfortable is beside the point; it's about finding the positives, not ignoring the negatives. If you learn to be uncomfortable, you become complacent, and don't do things to improve your life in real, tangible ways, like, say, negotiating a better salary. If there's a problem you need to solve with a method like this, that's great, but I would hesitate to recommend that people regularly incorporate unpleasant things into their daily life for the sole sake of them being unpleasant. That ultimately leaves you with less understanding of not only how to lead a pleasant life but also of how to improve the lives of the people around you, this latter goal being the core of entrepreneurship. E.g. if you try to use nothing but `cat` to edit files, you will never design a better text editor. If you walk to work, you won't be able to contribute to advances in vehicle technology. Ultimately I think our goal as humans is to reduce that sort of thing, not to increase it; otherwise we might as well revert to nomadic tribalism. To quote Edward Abbey: One final paragraph of advice: do not burn yourselves out. Be as I am — a reluctant enthusiast... a part-time crusader, a half-hearted fanatic. Save the other half of yourselves and your lives for pleasure and adventure. It is not enough to fight for the land; it is even more important to enjoy it. While you can. While it’s still here. So get out there and hunt and fish and mess around with your friends, ramble out yonder and explore the forests, climb the mountains, bag the peaks, run the rivers, breathe deep of that yet sweet and lucid air, sit quietly for a while and contemplate the precious stillness, the lovely, mysterious, and awesome space. Enjoy yourselves, keep your brain in your head and your head firmly attached to the body, the body active and alive, and I promise you this much; I promise you this one sweet victory over our enemies, over those desk-bound men and women with their hearts in a safe deposit box, and their eyes hypnotized by desk calculators. I promise you this; You will outlive the bastards.

Derbasti 15y ago
I agree with you, except for > If you walk to work, you won't be able to contribute to advances in vehicle technology. Are you implying that walking to work is an 'uncomfortable' thing like taking a cold shower? I may be misunderstanding you there, but I , for one, hate sitting in a car and suffering through morning-hour traffic jams. I hate searching for a parking spot. I much rather take my bike to work. You know, not to work out, but to breathe fresh morning air for once. To enjoy the sound of birds. Riding your bike, or walking, is exactly what that nice quite of yours is recommending. You can advance your vehicle technology as far as you like, but if that vehicle will be used for a distance that you could easily walk, it will never be effort well spent.

I don't know, I've tried turning the water icy cold for the last few minutes of the shower (based on an Art of Manliness article), and it seems like trying to artificially create meaning in something very trivial. I think there's value in changing things up so you don't get too comfortable, but to me this is about as meaningful or important as changing which brand of deodorant you use. Instead, I'd recommend things like going to see a play, listening to a new genre of music, taking cooking classes, etc.

jasonwilk 15y ago

I consistently take cold showers, and I actually really enjoy it. Has nothing to do with being tough. I just happen to feel a lot more awake post-shower, it's a lot more satisfying to dry off after (and when you get out of the shower, you aren't as cold), my skin feels better and Im quite possibly in a better mood. Also, if I have had a few drinks the night before, a cold shower is far superior than a hot shower.

bilban 15y ago
I agree, I take cold showers because I enjoy them - they are far from torture! I think the bloke that wrote the article totally missed that. In winter I even take a cold shower - and always feel far warmer after - even if the water is like ice. I run hot showers occasionally too. Though I never have any compulsion to leave the shower, I just want to stand there. The other thing is it never feels hot enough! Try it, just start with cold. You might even like it.

Tim Ferris talks about cold showers a lot in his 4 hour body book. Lately i've been 1) avoiding masturbation and 2) taking a hot shower followed immediately by full cold. I feel like I have more energy throughout the day, I'm more aggressive, and more confident. I've also started to eat brazil nuts. Cold showers (cold in general) stimulate fat loss. I always feel amazing after getting out of the cold too... like the wind was just completely knocked out of me. Almost like a high.

As someone who has taken many, many, many cold showers in Iraq and other unpleasant locales, if your character is so underdeveloped that taking a cold shower builds it up, you should be taking bigger strides. Edit: point being, cold showers are such an unbelievably mild form of suffering that suggesting they're "character builders" is painfully pretentious. Surprised this blogger of all people wrote this. He knows suffering.

jasonshen 15y ago
Hey Matt - thanks for your thoughts. I think mild is definitely in the eye of the beholder. Doing 50 pushups everyday would be a walk in the park for me - it might be absolute hell for someone else. A developer/designer might take 15 seconds to debug something that I could only manage after hours if not days of researching/Googling/struggling. As I mentioned in the post - I really like warm showers and hate being cold. For me, it really was quite difficult to force myself to take a cold shower. It's now much easier. You're right, I have gone through intense suffering - dislocating your knee, tearing all 4 ligaments and undergoing 5 surgeries will do that to you. So please have faith in me when I say that this activity was a challenge for me, was highly uncomfortable at first and required substantial willpower. I offer my experience as something others can draw from and suggest that this might be worth doing.
- Psyonic 15y ago
  I've been ending at least 80% of my showers with a minute or two of cold water since getting the 4 hour body a few months ago. It was definitely hard at first, then got easier, then got somewhat hard again (started to seem pointlessly masochistic), but all in all I feel it's been worthwhile.
tygorius 15y ago
suggesting they're "character builders" is painfully pretentious. No, it's just clear that the author has a wider understanding of the issue (and more compassion) than you display. It's like criticizing people for only being able to do a couple of pushups when they first visit the gym. The fact that they keep going to the gym and working at building strength is the important part, not how many repetitions they start out with. Recently deceased Aikido master Koichi Tohei[1] was a sickly child and had to take a year off from high school because he had pleurisy. Being forbidden to exercise, he started improving his character where he could: getting out of bed quickly and bathing by dumping buckets of cold water on himself.[2] He would later wind up leading troops in battle, so he hardly strikes me as a wimp. But since he would later stress that simple beginning exercise in some of his writings, just maybe he and the blogger aren't so "painfully pretentious" as you think.

I've been in the army. I've taken cold showers every day. Our commanders woke us up in 2am for a long run while carrying a rubber boat filled with water to the beach almost every day. When we finally got to the beach, we had to do push ups with our head inside the freezing water. I ran 20km carrying a fat man on a stretcher, cursing him under what remained of my breath. Guess what? I still read HN instead of getting shit done. Tolerance is only built on the same vector.

Cold showers just make me feel great. Never suffered of those. I also use them after workouts, as described here: http://paleohacks.com/questions/995/what-is-the-deal-with-cold-showers/1019#1019 http://paleohacks.com/questions/995/what-is-the-deal-with-co... "Invented by the French and used by virtually every elite athlete on the planet, it is often confused with some kind of torture. Right after working out, hop into the shower. First, cook yourself for no longer than 5 minutes in hot water, relax, get those blood vessels well dilated. Then slowly add cold water to the mix until it's so cold you can't stand it. Endure it. Focus the water on the back of your head and the muscles you just worked. Feel the blood vessels constrict. Stay under it for as long as it takes to really cool off - 2 to 3 minutes. The time it takes to cool down will increase as you adapt, and the temperature for cooling will decrease. Then, switch the hot water back on. The blood vessels will dilate, and inrushing blood will flush the lactic acid out. Start the cooking process again. Repeat at least two cycles and finish on cold. This induces a tonic effect and you'll rebound, flushing again as your body warms up in your clothes."

My dad used to tell me about the time he was in a cold, remote location (military), and he was the only one in their group who would take cold baths (from a snow-fed stream nearby); the others would warm up water and then bathe. The entire year he was there, he never fell ill; though the rest of the bunch came down with cold/flu with regularity. I know this is not scientific evidence, but just anecdotal. Thanks for the article; I had forgotten about his story, and now will try to work in cold showers slowly.

The ability to discipline yourself with nothing but the power of your mind is one of the single greatest skills a human can have. Put the ice cream cone down, and pick up a book, then go to the gym then finish up that big project you started 3 months ago. It is the art of taking control of your own body even though it hurts. It's what separates kings from bums lying around on the side of the road.

araneae 15y ago
Sure. It's great. So why waste it taking cold showers? This article is so completely pointless it makes my head spin.
raffaelc 15y ago
"It's what separates kings from bums lying around on the side of the road." Since kingship is, by definition, hereditary, I'm pretty sure that what separates kings from bums is largely a mere accident of birth. Just as we have evolved with an unrealistic perceptual bias to see lions in forest shadows - thinking you see one where there isn't one is low cost, failing to see one when there is one is a potentially lineage-ending move - we've also evolved to think that we have much more influence on the course of our lives than we do. We have limited self control; our conscious minds can really only inhibit unconscious impulses, and that only to a limited extent. Nevertheless, we've evolved to believe that we have much greater control than we do so that we continue to try to exercise the limited control that we do have, rather than not trying at all because we see our distinctly limited self control for what it is.

Aga 15y ago

A lot of commenters suggest to do something else instead of taking cold showers. I don't see the need to trade cold showers with anything as you certainly are able to e.g. lift weights AND take cold showers! Why not get the benefits of both? If nothing else, taking cold showers at least prepares you to having a swim in cold water (in a hole in the frozen sea) while attending sauna during winter time in Finland.. :-)

It needn't be a shower. Meditation, yoga, and some forms of martial art work just this way. Each of them trains you to accept discomfort without reacting to it. There's a Buddhist story where a student asks a teacher about the secret of correct practice. The answer: "Don't move." Meditation hurts. A lot. Your legs ache and often fall asleep, your lower back gets stiff. But you're not supposed to move. Over time you do become more flexible, but more importantly you learn to accept the pain without needing to fix it. It turns out that if you can focus on the moment, the pain isn't so bad - it's actually the fear of the pain lasting into the future that causes you stress. As Shunryu Suzuki (founder of SF Zen Center) said: "Don't move. Just die over and over. Don't anticipate. Nothing can save you now because you have only this moment." But there's nothing uniquely buddhist about this... My Berkeley tai chi instructor loves to have students hold postures for extended periods to the same effect. You move past this point where you think you're going to collapse and suddenly find a way to relax further into the form. And any serious yoga student will tell you that holding yoga poses for them accomplishes the same thing. Sounds like the cold shower had a similar effect for Jason. It's not macho, magical, or new agey - it's just a practice - though one that may seem odd in our can-do, fix-it-now culture. As we grow we learn that not every problem can be fixed, and devoting time to practices like these can teach you to be okay with that.

I applaud the general concept here but I think you're doing yourself a disservice if this is the extent to which you take this. Go take up rock climbing (toproping in a gym doesn't count), whitewater kayaking, or some other activity that will get you outdoors doing something involving real risk assessment and nontrivial consequences. If you're anything like me you'll find your attention to detail increases dramatically. Your ability to shrug off daily stresses will also increase. Compared to being gripped out of your mind 120 feet off the ground it's pretty hard to take some guy cutting you off in traffic seriously. Whatever you do, keep pushing your boundaries. Good luck!

The idea upon which this is based is called hormesis. See: http://en.wikipedia.org/wiki/Hormesis http://en.wikipedia.org/wiki/Hormesis http://en.wikipedia.org/wiki/Radiation_hormesis http://en.wikipedia.org/wiki/Radiation_hormesis http://en.wikipedia.org/wiki/Caloric_restriction http://en.wikipedia.org/wiki/Caloric_restriction The basic idea is that our ancestors were under stress so often that we evolved beneficial processes that kick in during times of stress, and only times of stress. Without the right environmental cues our bodies won't do the right thing. Imagine having to red-line your car for a few seconds in order to start the automatic oil-change.

I love this. Somebody decided to invent and plant a meme and see just how gullible people are. I'd image than several months later the authors will be laughing their posteriors off reading all the retweets, blog posts, and journals about people following the "procedure".

To find resources on the positive (or otherwise) effects of cold water, search for the term Dousing: http://en.wikipedia.org/wiki/Dousing http://en.wikipedia.org/wiki/Dousing There are scientific research on the topic as well, i.e. http://thesportjournal.org/article/impact-cold-water-immersion-5km-racing-performance http://thesportjournal.org/article/impact-cold-water-immersi...

Hilarious! Anyone read the Wikipedia article about "The Junction Boys", a college football team that Bear Bryant took to the town of Junction, Texas in the middle of summer? He made them do grueling practice in the blazing heat, and withheld water in order to toughen them up. At the end of this brutal regimen, the players who were left went on to... continue to suck and lose almost every game in the season.

I frequently take cold showers between sauna sessions. Both are extremes, in the sauna I like the feeling of hot steam making my skin shiver just after a splash of water on the heater. In a cold shower I like the initial gasp for air and the shiver down my spine before I get used to it. I do remember reading something about intensive chilling would improve my immune defense, but that just made me start doing this. Now I do it because it feels good to have some ice cool water after 10 minutes in the sauna giving you a slight fever.

For about four months in 2007 I took cold showers. Over time I found I was touching the water less and less and was developing hygiene problems. Additionally, I was taking longer and longer to jump in so the time savings were eroding. So, I stopped. To this day I do prefer less warm water than I did before the experiment, though.
