Coffee naps are better than coffee or naps alone

This is anecdotal, but I discovered this in undergrad - I would drink coffee before a class, and end up falling asleep briefly during a lecture, and then end up wide awake the rest of the time and more. It really does wonders.
rhema 12y ago
I've done this many times. It's really quite refreshing. I made a habit of this after lunch for a time. It helped give me an extra 3 or 4 hours of high productivity. The only downside is that it's better to chug the coffee, rather than sip it slowly.

I found this by experience few years ago. It works. At first, I started with naps, and drinking coffee after. Accidentally I had few times coffee before nap, and noticed the difference. But I don't recommend this kind of nap all the time - because after a while it's not that effective. So, after years of napping (I'm an expert - I became so good at napping, that I can fall a sleep in 1-2 minutes, and wake up without alarm after 15-20 minutes), my advice would be: take a nap after lunch, between 1 and 3pm, without coffee before nap. Only in special situations, when you are under high pressure and lots of work, take "coffee nap" as they call it in the article.

  > I can fall a sleep in 1-2 minutes, and wake up without alarm after 15-20 minutes Any advice on how you were able to achieve this ability? I always try to take a quick nap but can never fall asleep fas t enough for it to be effective.

    Earplugs + couch at a quiet place (e.g. library). If it's too loud for even earplugs, Emancipator's "Soon It Will Be Cold Enough" album works for when I'm on a bus/subway

    it takes practise. Likely you try and take a nap a few times, it takes too long and so the next day you don't bother. But if you can get through that it gets easier over time. Your body learns that it's "time to go to sleep". The other strategy is physical and mental exhaustion, for this I recommend starting a business and/or becoming a parent.

    Two techniques from my experience: - 'walk back' in your mind to center yourself away from forebrain activity and visual activity (this is a visualization technique) - cover your back with something insulated and/or warm. The less your back is staying tensed against chill air, the more physically relaxed you can be. I have a Thinsulate-filled sleeping bag that I use like a throw for this as it reflects body heat better than a comforter. Sleeping on a sofa, up against the back cushions, and noticing how it was good for naps, was what alerted me to this one.
    - twobits 12y ago
      Could you please expand on the "walk back" thing? Also, any links, books? Thanks.
      - crb3 12y ago
        Like I said, it's a visualization technique, and it works better if you have some experience with pushing your mental energies around. Practice in Wiccan grounding, centering and shielding helps (Google that or start with http://www.witchvox.com http://www.witchvox.com and start probing, I guess; I don't know of any instruction materials currently in print or online). This is my experience, so I describe it here in first-person... When I close my eyes, almost immediately my visual memory lights up with a "day review" which is like a daydream but for being something which I can direct, using pretty much the same visualization mechanism I use for data/code/schematic structures when I'm designing, coding or debugging. I can feel that forebrain activity as a slight heat just behind my forehead. It's great for overview and casual entertainment when I can afford the time, but not when I need a quick nap and it's keeping me conscious. I will the main weight of my awareness to recede from that frontal visualization viewplane, moving toward the back of my skull, deliberately dissociating from the visual activity, to where things feel like they're quieter and move slower. If, for motorcycling, where a less tightly-focused, more panoramic viewpoint is best for situational awareness, I take a half-step back, for quick napping I take several steps back. You can forcefully imagine the footsteps if it helps establish the change of center; after awhile, that mental positioning becomes familiar enough to dispense with the imagined physical/aural sound-effects. Sorry if it sounds all too Crafty or New-Age, but that's how I live.

    Breathe in a count of 2 and out a count of 1. Sleep with your mouth open, but breathe only through your nose. Remember that quiet resting with eyes shut is 80% as good as sleeping when it comes to naps.
  - maroonblazer 12y ago
    When I started meditating I found it much easier to fall asleep quickly. The 'opening game' of most, if not all, mindfulness meditation is simply relaxing your body and preparing for the meditation. Turns out this is something you can get better at with practice; at least I did. Pick up the Headspace app. You get several meditations for free and those should be enough to arm you with what you need to learn "speed relaxing". https://www.headspace.com/headspace-meditation-app https://www.headspace.com/headspace-meditation-app
  - practicalpants 12y ago
    I can at least say when I am habitually sleep deprived I find it easy to fall asleep on a whims notice. If I get a proper 8-9 hours of sleep, I find it impossible to nap. Maybe the insta-napping is only possible due to a more fundamental lack of sleep issue?
- bwanab 12y ago
  I don't sleep well at night. I never have. But, after lunch (and after perusing HN for a few minutes), I start feeling that dull sensation like my brain is trying to shut down. If, at that point, I get into a reasonably comfortable position (doesn't have to be lying down, just rest your head on a table or lean back in a chair with head supported), close my eyes and allow my thoughts to wander. In 5 to 15 minutes the world looks like a much better place. I really think the key is closing your eyes. I've read (no citation available) that the vision system requires a huge amount of brain activity and that by shutting your eyes you can achieve a large sleep like win even if you don't sleep.
smegmalife 12y ago
Hardest part for me is falling asleep in such a short period of time, especially during the day. When I have succeeded with these naps, it's been amazing.
staunch 12y ago
> ...it takes around 20 minutes for the caffeine to get through your gastrointestinal tract and bloodstream anyway. This isn't really true, right? On an empty stomach a strong coffee seems to get me high as a kite in about two minutes. I've been doing this coffee+nap thing for a long time. It definitely works for me. My trick for falling asleep reliably and quickly is listening to an audiobook.
- nmjohn 12y ago
  There is a lot of it depends. On an empty stomach 20 minutes does seem a bit long. However you're also conditioned to the feeling you expect coffee to provide, so the initial jolt of energy may have almost nothing to do with the actual caffeine and more to do with the thought of the caffeine.
- crb3 12y ago
  How do you drink your coffee? If you sugar it, you're not dealing with just the caffeine.
  - staunch 12y ago
    I don't but how would sugar beat caffeine into the blood stream?
    - adricnet 12y ago
      Absorption of some nutrients happens in the mouth and gums. Perhaps the poster is speculating that sugar (simple carbs?) molecules might be quickly absorbed into the bloodstream through the mouth and esophagus while caffeine has to be digested in the stomach?
virtuabhi 12y ago
I have read this before. I do not understand how you can sleep for 20 minutes. It takes more than 15 minutes just to fall asleep.
- stronglikedan 12y ago
  Not for everyone. For me, yes, at least 15 minutes, but my SO can often go out in less than 5. I never take naps for that reason, and she takes them frequently. Perhaps there's a correlation between the time it takes to fall asleep and the frequency of naps.
- scrollaway 12y ago
  Certainly depends on how tired you are. I work at home, so I sleep around my own schedule as much as I want to and almost always feel rested. But when I am missing an hour or two of sleep (which a lot of people are, every damn day), I fall asleep in minutes given the opportunity in the middle of the day.
- hatu 12y ago
  Especially since I think coffee for me is mostly a placebo. I know when I drink coffee I'm supposed to be more awake so there's no way I could take a nap after drinking one.
- codereflection 12y ago
  Depends on the person, so this isn't going to work for everyone. I can fall asleep in ~2 min. It's a curse when I need to stay awake.
- kmfrk 12y ago
  I find just trying to sleep for twenty minutes can be rejuvenating enough for a powernap. I can't fall asleep on a whim either.
- DaniFong 12y ago
  Read this carefully: I used to think this way as well. This thinking lead me to the exact wrong strategy for naps. There are many stages of sleep; stage 1 through 4, and REM sleep. These, it is hypothesized, have distinct physiological functions. Most importantly for this discussion, waking up out of each have very different effects. Waking from stage 1 sleep makes you feel immediately refreshed, and people perform better immediately have tests of mental acuity. This is also true of REM sleep; additionally you often remember dreams. Stage 2 is also good. A good 30 minutes afterwards, you will feel better rested, and your mental acuity will rise; for longer than from stage 1, but it is a delayed effect. But if you wake up out of a deeper sleep cycle, you get 'sleep inertia.' Mental acuity plummets. You feel poorly rested and ill. The problem: The body is often not even aware that you are sleeping in stage 1 sleep. You are in a different physiological stage, but you may not have lost consciousness. You usually are in this stage from minute 5 onto minute 10. And in stage two up to about 15-20 minutes. After that, you can fall into a deeper sleep; which waking up from is very problematic. I used to set my alarm for 30 minutes. I'd way up, feel even more tired, and set my alarm for 30 minutes again. This was ruining my life. --- tl;dr Even if you don't lose consciousness, you can still be 'sleeping' and a nap of 20 minutes will greatly help you feel healthy and well rested.

This is definitely how siesta time goes in Southern Spain. It seemed an odd habbit when I was introduced to it but it definitely does the job.
educated_idiot 12y ago
Can confirm it works. Have done this often in about 3-4 years. It's easy to fall asleep really fast if you are actually tired (physically or mentally)...doesn't work if you are just bored and wanna pep yourself up.
shimon_e 12y ago
Sounds like this would pair well with specially designed time release caffeine capsules that release 20 minutes before you wake up.
x0x0 12y ago
coffee naps? It's like Joseph is talking to my heart.
jdnier 12y ago
I have noticed this occasionally on weekends, when the luxury of a nap is more practical. I'll have a small late-morning coffee, feel cozy/sleepy, then nap briefly and wake up refreshed. Seemed crazy at the time. I'd guess you need to feel somewhat tired for this to work (and I am able to fall asleep quickly).
giardini 12y ago
For those who have trouble falling asleep quickly I recommend good earplugs, a quiet place where you can nap undisturbed and a dark opaque towel or cloth with which you can cover your eyes and block light completely. Given that, there's little to prevent sleep once you've settled in.
copperx 12y ago
I have found that a Provigil/Nuvigil nap works wonders. Take a Provigil and take a nap. When you wake up you'll be crisp morning-fresh.
- 8_hours_ago 12y ago
  I used to do similar before pulling all-nighters in college. I would take an adderall and go to sleep around 11pm, my normal bedtime, then after a 30 minute nap I'd be wide awake and ready to conquer whatever project I had been procrastinating on.
- dredwerker 12y ago

      They prescribe modafinil for sleep apnea? I have apnea and I'm curious because I've never heard this. I've heard it is used for narcolepsy.
  - JonnieCache 12y ago
    It's a brand name for modafinil.
tempestn 12y ago
Is there any downside to doing this? It seems like there must be a reason why the adenosine signals that it's time to sleep - like your brain actually needs that rest to recuperate properly after activity. Does a "coffee nap" (or caffeine in general) lead to increased fatigue once the effects wear off? Although I guess to some extent if you're going to ignore the sleep signal otherwise, there likely isn't much harm in feeling alert while doing so, except inasmuch as the alert feeling causes you to tax your brain more than you otherwise would.
- Retric 12y ago
  Natural sleep cycles vary not just by person but also by age. There is some evidence that a small community with 0 to 70 year olds will always have someone awake. Which would seem like a likely survival adaptation. Which suggests sleep cycles may relate to more than just biological need.
  - electromagnetic 12y ago
    I've read this before too, I cant remember where. Basically your 25-50 year old typically sleeps from about midnight to 8am. Teens and young adults typically sleep much later, with the "crack of dawn" not being uncommon and the elderly typically awake at the "crack of dawn". Basically most preditors are active either just after dark, or in the late morning. Teens are typically strong (a 13 year old male is as strong as your average adult female), alert and they have the best vision, and noise making in the night would keep predators and scavengers away. Evening predators likely weren't a great risk, but scavengers definitely would be an issue. Adults are obviously the strongest and most alert, and are awake when the most dangerous animals are also awake: lions, tigers, hippos, etc. The elderly are our weakest, their vision is poor and their alertness becomes questionable. However, there's theories we live so long after infertility sets in specifically for the reason they care for the young. Both infants and the elderly have surprisingly similar sleeping patterns. Predators are least active in the early mornings and so are most dangers. Insects and reptiles (venomous things) are least active in the coldest hours of the day, which is right around dawn.

Caffeine naps are my secret "crunch time" weapon. It's astounding how effective they are - it feels like a reboot. I wake up feeling like I've been out for 8 hours. The effect only lasts for a couple of hours post-nap, but it's often enough to get you over the hump.
blutoot 12y ago
What is the tolerance level for naps in silicon valley companies (both big and small)? Does it depend on the role/position? Wouldn't they rather have all their employees down mugs of coffee instead of taking even a quick nap?
MichaelGG 12y ago
This works well with other stimulants and other medications too. Take methylphenidate and an opioid, take a quick nap, wake up feeling fantastic. It's also got emotional benefits. If you are feeling down, then simply waiting for the medicine to do its job can make things worse, as your mind goes in a negative spiral. Taking a nap can give you peace that you're just putting everything aside and going to concentrate on the warmth of the nap and a dream. And before you know it, bam - everything's perfect again.
ArcticCelt 12y ago
I wish I was able to take naps. Do people can really fall asleep on command just like that when they have some spare minutes in their day? Shit, even when I am sleep deprived, I can barely fall asleep in my own bed, sometimes it literally take me hours. When I manage to take a nap it's usually involuntary by falling asleep in front of the TV.
- joshschreuder 12y ago
  I'm exactly the same, I find it very difficult to nap during the day even when sleep deprived. It takes me a long time to fall asleep.
  - weaponofchoice 12y ago
    Used to be similar for me. Until I discovered deep meditation (http://www.amazon.com/Deep-Meditation-Pathway-Personal-Freedom/dp/097646554X http://www.amazon.com/Deep-Meditation-Pathway-Personal-Freed...). Summarized: Repeat a chant, such as 'I am' (or any phrase of your choosing) for about 5 minutes, focusing on what the chant-phrase sounds like in your mind. With the phrase 'I am', you would try to feel the sounds 'A-Y-A-M' being pronounced in your mind, without ever vocalizing it. Gets me napping within 5 minutes, wake up charged up for a massively productive session. I hope you'll give it a try sometime.
- electromagnetic 12y ago
  Ditto this. My wife can nap no problem. I might nap every couple months, and its basically a disrupted sleep and not a nap. I wake up feeling terrible; groggy, mild headache, irritable. I'd have been better off not napping as it inevitably comes when I've got so much to do and no energy and that "if I have a quick nap I'll feel refreshed and be ready to work!" Nope!

A 20 minute nap does way more for me than a cup of coffee, but this is a promising approach I'll definitely try.
mmanfrin 12y ago
After a couple months of protracted late nights at a startup I worked for, I came up with an idea for a place which would offer by-the-hour nap+shower+coffee pods. You'd go in, pay $20 or whatever, have access to a shower and a bed, and at the end (or beginning) you'd get a coffee of your choice (if after, it would be ready for you when your nap was over). I think this could do really well in Soma or the Financial District in SF. Just gotta enforce one-person-one-rule so that it doesnt become a place for prostitution.
- callmeed 12y ago
  I don't live in SF but I think this would be viable. I'd even use it when I was in town. I think you'd also get customers from people who bike to work or workout at lunch but don't have access to a shower (assuming the location was good).

  So like a love hotel (http://en.wikipedia.org/wiki/Love_hotel http://en.wikipedia.org/wiki/Love_hotel), but sans coupling. Or like a capsule hotel (http://en.wikipedia.org/wiki/Capsule_hotel http://en.wikipedia.org/wiki/Capsule_hotel), but with attached shower. Even on non-prime real-estate (which does that exist in SF?), I don't think you could hit your $20 price point with the amount of housekeeping needed for a bed and shower. Even if you could, after a week your staff might hate you. :-)

I don't doubt, though, that even in Japan there's a niche for specifically targeted establishments of the kind described by grandparent.

Serious Question: What can I do where I really need to do this in the afternoon (and would of course really increase productivity), but I'm not allowed to nap at work?
- halfcat 12y ago
  Best bet is to leave work for lunch. Sit in your car if you have one, wearing sunglasses. Best if your car has tinted windows. If your building has a parking garage, that is ideal, less chance of random person thinking you are dead and calling the cops. If you don't have a car, bathroom stalls might work, if you can find a clean spot where you can sit on the toilet and lean your head against the stall wall. Wiping down the area where you lay your head with hand sanitizer might be a good move. Some libraries have private rooms you can reserve for studying. If it's too hard at your job, you may have to decide whether it's worth changing jobs. It sounds silly, but if taking a siesta would have a significant positive impact on your productivity (and it does for many people), then changing jobs is a reasonable step IMO.
Multiplayer 12y ago
The Jawbone up is the BOMB of all bombs for taking naps. Put it in nap mode and it waits for you to fall asleep before setting the alarm. So you can get a proper nap without wondering whether you're taking too long to fall asleep, etc. It can also attempt to time your nap based on your latest sleep patterns. No idea how effective this is. I love this thing just for it's nap mode.
shire 12y ago
It's hard for me to just take a nap on command in the middle of the day. I wish it was easy for me because a nap would help a lot.
darkmethod 12y ago
I can attest to this. I've done this several times for the energy boost. I didn't know there is a name for it; "coffee nap". I tend to add dance/techno music to know when to wake up and get back to work.
jqm 12y ago
(from the article) "energy drinks are disgusting.." I disagree. Monsters in particular I find delicious. (I try not to drink them often though... they tend to really hype me up then wear me out not long after).
- johnward 12y ago
  I don't like monster but rockstar zero carb or sugar free does it for me. Also anything sugar free with erythritol as a sweetener is gross to me. It tastes way sweeter than sugar. I wish I could acquire a taste for coffee because it seems like the healthiest way to get caffeine, but if I have to load it with sugar and cream it defeats the point.

This is a well known practise in Spain. I com from Spain and I have always seen my family (parents and grandparents) drinking coffee after lunch and, then, doing a nap on the couch. Usually, we sit on the couch, take the coffee together and then every person takes a newspaper or magazine and after a few minutes of pseudo-reading everybody is sleeping or in a state of deep relaxation. We sleep for 20 minutes. That's all. I guess this is very common in Spain. This works well because we often take lunch at home. But, now that I have lunch at the office, I do the same. I have a 1 hour pause. The first half hour I have lunch, then I take the coffee and I go to the office to sleep on the floor, on a very thin mattress. If my brain is too active, I listen to a foreign radio station with my iPhone. I like to listen to ICI Radio Canada (in French). When I have lunch here, they broadcast the morning news and commentary. The news are about stuff happening in Quebec. It is interesting enough for me to forget the work stuff, and dull enough to induce me into a deeper relaxation state, which allows me to fall sleep fast. Being the broadcast in a foreing language, also helps to fall sleep. I often dream during this 20-30 minutes naps. An interesting detail is that I had to learn this habit. I remember being a child and being pissed off because I wasn't allowed to make noise after lunch. Now, that I'm a father, the roles are changing and I'm the one sleeping after lunch. By the way, at night, in order to fall sleep, I never take phones, tablets or computers to my bedroom. Instead, I take a shortwave radio and I tune the BBC world service news (fortunately, in Spain we can hear the broadcast directed to Africa). I put a 30 minutes timer on the radio and I almost never hear it stopping, because I fall sleep before. The day that the BBC will shut the SW broadcast, I guess I will take a bluetooth headset or speaker to my bedroom, but not the iPhone. It is very important to avoid computers in the bedroom.
- gurtwo 12y ago
  As a spaniard myself, I can confirm this is an accurate description of what siesta looks like on most cases. Short nap on the couch after a coffee, for those who take lunch at home, or just on the weekends otherwise.
  - aeire 12y ago
    hmm.. i believe this is pretty the same in Greece, at least during weekends, holidays and work-free days. In every lunch-gathering with close relatives, or close friends, at least one or two person take a short nap on the couch after the lunch, while the rest are having a relaxed and low voice chat. Usually the persons who fall asleep are males.
kbart 12y ago
It's thought this practice is a common knowledge, strange that it's "news". I have been using this for years.
vegancap 12y ago
I don't know if it's just me but, how the hell do you nap?! I tried once, and I was still wide awake when my alarm that was supposed to wake me up from my hour long nap went off. I'd have to be really drunk, or not have slept for days in order to nap. I don't understand how people just nap on queue, I feel like I'm missing a trick here :(
Dewie 12y ago
I'm thinking of putting a mattress beneath my desk/cubicle. I have a hard time falling asleep on command or taking naps at all. Maybe properly lying down instead of lying kind of uncomfortably on the floor will help with that. This is in a university setting, so I have no managers to worry about. The only problem might be noise (I often sleep with earplugs anyway), and weird looks.
rootbear 12y ago
I have read before that drinking coffee before a short nap is a good combination. It's nice to read that someone has actually tested it. I can't always do it at work but I have used this method at home and it works well. One other suggestion I follow is that I don't take short naps lying down. That encourages my body to go into a longer, deeper sleep. I nap sitting in a comfy chair, in a quiet, dim room if possible. It's very refreshing; I'm more alert and productive for the rest of the day.
danelectro 12y ago
I support the napping for productivity without having artificial stimulants (OK, natural organic drugs) involved. The studies likely involved mostly habitual users rather than unindoctrinated subjects, but from the abstracts' documentation it is difficult to be sure. Perhaps the researchers did not recognize the distinction and just selected random participants, therefore likely to include mostly habitual users. When I was a caffeine addict (habitual user) I could also sleep after ingestion. In fact without a fix right before bedtime it was more difficult to get to sleep because nominal concentration level was unsatisfied, resulting more in agitation than identifiable craving. A nice hit would actually help me relax. I was not the only one who could relate to this as an indication of true addiction, where you need the substance just to be normal. Complete withdrawal took a few weeks (of hellish tiredness, achiness, and irritability) but after this it was even easier to more alertly conduct high-stamina activities and out-perform my still-addicted colleagues without the toxic load on my system. Sleep & nap much more productively without it after kicking the habit too. Sure can write a lot better code when drug (addiction) free as well. When I do feel it's necessary (never for marathon coding), a single cup of coffee (after I have already been awake 24hrs and need a little boost) naturally keeps my otherwise drug-free system awake for the next 24hrs easily which can be helpful for things like long-distance driving once or twice per year. As an addict I would have needed two or three times my nominal habitual doses to feel as alert on those same lonely roads. To me coding does not benefit from this type of non-stop alertness, even if you are working to exhaustion, when tiredness truly comes a plain nap is better whether it is after 6hrs, 12hrs, 20hrs, whatever, then freshly go into another session, exahustion relieved. Same with driving too, but if the schedule is too tight, a couple times a year will not make you a habitual user like everyday dosage does. I'd rather drive slow for long hours than exceed the speed limit, waste energy, and prematurely wear out my machinery. YMMV [0] but just because everybody does caffeine won't make it good for you, especially in the long run. [0] depending largely on body weight, metabolism, and dosage, and for driving, road speed

How long can coffee napping be used, and what are the after effects? The article says the test subjects used it to good effect for 24 hours. I wonder if the following day was a compete productivity waste.
duffx 12y ago
Keep in mind that after 2-3 weeks of habitual coffee drinking, your body acclimates to the effects of caffeine and you no longer receive a performance benefit. At that point all drinking coffee does for you is ward off the effects of withdrawal and return you to baseline performance levels - until the effects wear off and withdrawal kicks in again, at which point your performance is below average. Caffeine is best used strategically, which means not every day. Save it for days where you're feeling particularly low energy, or need a boost to tackle a problem you're not particularly excited about doing. That said, the half-life of caffeine is around 6 hours, which means if you have a coffee at 3pm, at 3am you still have a quarter-cup's worth of caffeine in your system, preventing you from entering deep sleep. So even then I'd keep caffeine as a first-thing-in-the-morning type of deal. Naps I'm a big fan of. I take one every day after lunch. The trick is to simply lay down and close your eyes for 20 minutes. Don't worry if you fall asleep or not - just give your eyes a rest. For the first few days/weeks, you might not fall asleep. But eventually your body grows accustomed to the ritual and it becomes easier to actually fall asleep at hat time.

What's the point? Unless you work at Google, at home, or at a super trendy startup, or in your own big office with a sofa in it, this doesn't really mean anything for you because you have no place to take a nap.

This is anecdotal, but I discovered this in undergrad - I would drink coffee before a class, and end up falling asleep briefly during a lecture, and then end up wide awake the rest of the time and more. It really does wonders.

rhema 12y ago

I've done this many times. It's really quite refreshing. I made a habit of this after lunch for a time. It helped give me an extra 3 or 4 hours of high productivity. The only downside is that it's better to chug the coffee, rather than sip it slowly.

I found this by experience few years ago. It works. At first, I started with naps, and drinking coffee after. Accidentally I had few times coffee before nap, and noticed the difference. But I don't recommend this kind of nap all the time - because after a while it's not that effective. So, after years of napping (I'm an expert - I became so good at napping, that I can fall a sleep in 1-2 minutes, and wake up without alarm after 15-20 minutes), my advice would be: take a nap after lunch, between 1 and 3pm, without coffee before nap. Only in special situations, when you are under high pressure and lots of work, take "coffee nap" as they call it in the article.

> I can fall a sleep in 1-2 minutes, and wake up without alarm after 15-20 minutes Any advice on how you were able to achieve this ability? I always try to take a quick nap but can never fall asleep fas t enough for it to be effective.

  Earplugs + couch at a quiet place (e.g. library). If it's too loud for even earplugs, Emancipator's "Soon It Will Be Cold Enough" album works for when I'm on a bus/subway

  it takes practise. Likely you try and take a nap a few times, it takes too long and so the next day you don't bother. But if you can get through that it gets easier over time. Your body learns that it's "time to go to sleep". The other strategy is physical and mental exhaustion, for this I recommend starting a business and/or becoming a parent.

  Two techniques from my experience: - 'walk back' in your mind to center yourself away from forebrain activity and visual activity (this is a visualization technique) - cover your back with something insulated and/or warm. The less your back is staying tensed against chill air, the more physically relaxed you can be. I have a Thinsulate-filled sleeping bag that I use like a throw for this as it reflects body heat better than a comforter. Sleeping on a sofa, up against the back cushions, and noticing how it was good for naps, was what alerted me to this one.
  - twobits 12y ago
    Could you please expand on the "walk back" thing? Also, any links, books? Thanks.
    - crb3 12y ago
      Like I said, it's a visualization technique, and it works better if you have some experience with pushing your mental energies around. Practice in Wiccan grounding, centering and shielding helps (Google that or start with http://www.witchvox.com http://www.witchvox.com and start probing, I guess; I don't know of any instruction materials currently in print or online). This is my experience, so I describe it here in first-person... When I close my eyes, almost immediately my visual memory lights up with a "day review" which is like a daydream but for being something which I can direct, using pretty much the same visualization mechanism I use for data/code/schematic structures when I'm designing, coding or debugging. I can feel that forebrain activity as a slight heat just behind my forehead. It's great for overview and casual entertainment when I can afford the time, but not when I need a quick nap and it's keeping me conscious. I will the main weight of my awareness to recede from that frontal visualization viewplane, moving toward the back of my skull, deliberately dissociating from the visual activity, to where things feel like they're quieter and move slower. If, for motorcycling, where a less tightly-focused, more panoramic viewpoint is best for situational awareness, I take a half-step back, for quick napping I take several steps back. You can forcefully imagine the footsteps if it helps establish the change of center; after awhile, that mental positioning becomes familiar enough to dispense with the imagined physical/aural sound-effects. Sorry if it sounds all too Crafty or New-Age, but that's how I live.

  Breathe in a count of 2 and out a count of 1. Sleep with your mouth open, but breathe only through your nose. Remember that quiet resting with eyes shut is 80% as good as sleeping when it comes to naps.

  When I started meditating I found it much easier to fall asleep quickly. The 'opening game' of most, if not all, mindfulness meditation is simply relaxing your body and preparing for the meditation. Turns out this is something you can get better at with practice; at least I did. Pick up the Headspace app. You get several meditations for free and those should be enough to arm you with what you need to learn "speed relaxing". https://www.headspace.com/headspace-meditation-app https://www.headspace.com/headspace-meditation-app

  I can at least say when I am habitually sleep deprived I find it easy to fall asleep on a whims notice. If I get a proper 8-9 hours of sleep, I find it impossible to nap. Maybe the insta-napping is only possible due to a more fundamental lack of sleep issue?
bwanab 12y ago
I don't sleep well at night. I never have. But, after lunch (and after perusing HN for a few minutes), I start feeling that dull sensation like my brain is trying to shut down. If, at that point, I get into a reasonably comfortable position (doesn't have to be lying down, just rest your head on a table or lean back in a chair with head supported), close my eyes and allow my thoughts to wander. In 5 to 15 minutes the world looks like a much better place. I really think the key is closing your eyes. I've read (no citation available) that the vision system requires a huge amount of brain activity and that by shutting your eyes you can achieve a large sleep like win even if you don't sleep.

smegmalife 12y ago

Hardest part for me is falling asleep in such a short period of time, especially during the day. When I have succeeded with these naps, it's been amazing.

> ...it takes around 20 minutes for the caffeine to get through your gastrointestinal tract and bloodstream anyway. This isn't really true, right? On an empty stomach a strong coffee seems to get me high as a kite in about two minutes. I've been doing this coffee+nap thing for a long time. It definitely works for me. My trick for falling asleep reliably and quickly is listening to an audiobook.

nmjohn 12y ago
There is a lot of it depends. On an empty stomach 20 minutes does seem a bit long. However you're also conditioned to the feeling you expect coffee to provide, so the initial jolt of energy may have almost nothing to do with the actual caffeine and more to do with the thought of the caffeine.

How do you drink your coffee? If you sugar it, you're not dealing with just the caffeine.

  - adricnet 12y ago
    Absorption of some nutrients happens in the mouth and gums. Perhaps the poster is speculating that sugar (simple carbs?) molecules might be quickly absorbed into the bloodstream through the mouth and esophagus while caffeine has to be digested in the stomach?

virtuabhi 12y ago

I have read this before. I do not understand how you can sleep for 20 minutes. It takes more than 15 minutes just to fall asleep.

stronglikedan 12y ago
Not for everyone. For me, yes, at least 15 minutes, but my SO can often go out in less than 5. I never take naps for that reason, and she takes them frequently. Perhaps there's a correlation between the time it takes to fall asleep and the frequency of naps.
scrollaway 12y ago
Certainly depends on how tired you are. I work at home, so I sleep around my own schedule as much as I want to and almost always feel rested. But when I am missing an hour or two of sleep (which a lot of people are, every damn day), I fall asleep in minutes given the opportunity in the middle of the day.
hatu 12y ago
Especially since I think coffee for me is mostly a placebo. I know when I drink coffee I'm supposed to be more awake so there's no way I could take a nap after drinking one.

DaniFong 12y ago
Read this carefully: I used to think this way as well. This thinking lead me to the exact wrong strategy for naps. There are many stages of sleep; stage 1 through 4, and REM sleep. These, it is hypothesized, have distinct physiological functions. Most importantly for this discussion, waking up out of each have very different effects. Waking from stage 1 sleep makes you feel immediately refreshed, and people perform better immediately have tests of mental acuity. This is also true of REM sleep; additionally you often remember dreams. Stage 2 is also good. A good 30 minutes afterwards, you will feel better rested, and your mental acuity will rise; for longer than from stage 1, but it is a delayed effect. But if you wake up out of a deeper sleep cycle, you get 'sleep inertia.' Mental acuity plummets. You feel poorly rested and ill. The problem: The body is often not even aware that you are sleeping in stage 1 sleep. You are in a different physiological stage, but you may not have lost consciousness. You usually are in this stage from minute 5 onto minute 10. And in stage two up to about 15-20 minutes. After that, you can fall into a deeper sleep; which waking up from is very problematic. I used to set my alarm for 30 minutes. I'd way up, feel even more tired, and set my alarm for 30 minutes again. This was ruining my life. --- tl;dr Even if you don't lose consciousness, you can still be 'sleeping' and a nap of 20 minutes will greatly help you feel healthy and well rested.

coffee naps? It's like Joseph is talking to my heart.

jdnier 12y ago

I have noticed this occasionally on weekends, when the luxury of a nap is more practical. I'll have a small late-morning coffee, feel cozy/sleepy, then nap briefly and wake up refreshed. Seemed crazy at the time. I'd guess you need to feel somewhat tired for this to work (and I am able to fall asleep quickly).

giardini 12y ago

For those who have trouble falling asleep quickly I recommend good earplugs, a quiet place where you can nap undisturbed and a dark opaque towel or cloth with which you can cover your eyes and block light completely. Given that, there's little to prevent sleep once you've settled in.

tempestn 12y ago

Is there any downside to doing this? It seems like there must be a reason why the adenosine signals that it's time to sleep - like your brain actually needs that rest to recuperate properly after activity. Does a "coffee nap" (or caffeine in general) lead to increased fatigue once the effects wear off? Although I guess to some extent if you're going to ignore the sleep signal otherwise, there likely isn't much harm in feeling alert while doing so, except inasmuch as the alert feeling causes you to tax your brain more than you otherwise would.

Retric 12y ago
Natural sleep cycles vary not just by person but also by age. There is some evidence that a small community with 0 to 70 year olds will always have someone awake. Which would seem like a likely survival adaptation. Which suggests sleep cycles may relate to more than just biological need.
- electromagnetic 12y ago
  I've read this before too, I cant remember where. Basically your 25-50 year old typically sleeps from about midnight to 8am. Teens and young adults typically sleep much later, with the "crack of dawn" not being uncommon and the elderly typically awake at the "crack of dawn". Basically most preditors are active either just after dark, or in the late morning. Teens are typically strong (a 13 year old male is as strong as your average adult female), alert and they have the best vision, and noise making in the night would keep predators and scavengers away. Evening predators likely weren't a great risk, but scavengers definitely would be an issue. Adults are obviously the strongest and most alert, and are awake when the most dangerous animals are also awake: lions, tigers, hippos, etc. The elderly are our weakest, their vision is poor and their alertness becomes questionable. However, there's theories we live so long after infertility sets in specifically for the reason they care for the young. Both infants and the elderly have surprisingly similar sleeping patterns. Predators are least active in the early mornings and so are most dangers. Insects and reptiles (venomous things) are least active in the coldest hours of the day, which is right around dawn.

Caffeine naps are my secret "crunch time" weapon. It's astounding how effective they are - it feels like a reboot. I wake up feeling like I've been out for 8 hours. The effect only lasts for a couple of hours post-nap, but it's often enough to get you over the hump.

blutoot 12y ago

What is the tolerance level for naps in silicon valley companies (both big and small)? Does it depend on the role/position? Wouldn't they rather have all their employees down mugs of coffee instead of taking even a quick nap?

MichaelGG 12y ago

This works well with other stimulants and other medications too. Take methylphenidate and an opioid, take a quick nap, wake up feeling fantastic. It's also got emotional benefits. If you are feeling down, then simply waiting for the medicine to do its job can make things worse, as your mind goes in a negative spiral. Taking a nap can give you peace that you're just putting everything aside and going to concentrate on the warmth of the nap and a dream. And before you know it, bam - everything's perfect again.

ArcticCelt 12y ago

I wish I was able to take naps. Do people can really fall asleep on command just like that when they have some spare minutes in their day? Shit, even when I am sleep deprived, I can barely fall asleep in my own bed, sometimes it literally take me hours. When I manage to take a nap it's usually involuntary by falling asleep in front of the TV.

joshschreuder 12y ago
I'm exactly the same, I find it very difficult to nap during the day even when sleep deprived. It takes me a long time to fall asleep.

  Used to be similar for me. Until I discovered deep meditation (http://www.amazon.com/Deep-Meditation-Pathway-Personal-Freedom/dp/097646554X http://www.amazon.com/Deep-Meditation-Pathway-Personal-Freed...). Summarized: Repeat a chant, such as 'I am' (or any phrase of your choosing) for about 5 minutes, focusing on what the chant-phrase sounds like in your mind. With the phrase 'I am', you would try to feel the sounds 'A-Y-A-M' being pronounced in your mind, without ever vocalizing it. Gets me napping within 5 minutes, wake up charged up for a massively productive session. I hope you'll give it a try sometime.
electromagnetic 12y ago
Ditto this. My wife can nap no problem. I might nap every couple months, and its basically a disrupted sleep and not a nap. I wake up feeling terrible; groggy, mild headache, irritable. I'd have been better off not napping as it inevitably comes when I've got so much to do and no energy and that "if I have a quick nap I'll feel refreshed and be ready to work!" Nope!

mmanfrin 12y ago

After a couple months of protracted late nights at a startup I worked for, I came up with an idea for a place which would offer by-the-hour nap+shower+coffee pods. You'd go in, pay $20 or whatever, have access to a shower and a bed, and at the end (or beginning) you'd get a coffee of your choice (if after, it would be ready for you when your nap was over). I think this could do really well in Soma or the Financial District in SF. Just gotta enforce one-person-one-rule so that it doesnt become a place for prostitution.

callmeed 12y ago
I don't live in SF but I think this would be viable. I'd even use it when I was in town. I think you'd also get customers from people who bike to work or workout at lunch but don't have access to a shower (assuming the location was good).

Serious Question: What can I do where I really need to do this in the afternoon (and would of course really increase productivity), but I'm not allowed to nap at work?

halfcat 12y ago
Best bet is to leave work for lunch. Sit in your car if you have one, wearing sunglasses. Best if your car has tinted windows. If your building has a parking garage, that is ideal, less chance of random person thinking you are dead and calling the cops. If you don't have a car, bathroom stalls might work, if you can find a clean spot where you can sit on the toilet and lean your head against the stall wall. Wiping down the area where you lay your head with hand sanitizer might be a good move. Some libraries have private rooms you can reserve for studying. If it's too hard at your job, you may have to decide whether it's worth changing jobs. It sounds silly, but if taking a siesta would have a significant positive impact on your productivity (and it does for many people), then changing jobs is a reasonable step IMO.

Multiplayer 12y ago

The Jawbone up is the BOMB of all bombs for taking naps. Put it in nap mode and it waits for you to fall asleep before setting the alarm. So you can get a proper nap without wondering whether you're taking too long to fall asleep, etc. It can also attempt to time your nap based on your latest sleep patterns. No idea how effective this is. I love this thing just for it's nap mode.

pqs 12y ago

This is a well known practise in Spain. I com from Spain and I have always seen my family (parents and grandparents) drinking coffee after lunch and, then, doing a nap on the couch. Usually, we sit on the couch, take the coffee together and then every person takes a newspaper or magazine and after a few minutes of pseudo-reading everybody is sleeping or in a state of deep relaxation. We sleep for 20 minutes. That's all. I guess this is very common in Spain. This works well because we often take lunch at home. But, now that I have lunch at the office, I do the same. I have a 1 hour pause. The first half hour I have lunch, then I take the coffee and I go to the office to sleep on the floor, on a very thin mattress. If my brain is too active, I listen to a foreign radio station with my iPhone. I like to listen to ICI Radio Canada (in French). When I have lunch here, they broadcast the morning news and commentary. The news are about stuff happening in Quebec. It is interesting enough for me to forget the work stuff, and dull enough to induce me into a deeper relaxation state, which allows me to fall sleep fast. Being the broadcast in a foreing language, also helps to fall sleep. I often dream during this 20-30 minutes naps. An interesting detail is that I had to learn this habit. I remember being a child and being pissed off because I wasn't allowed to make noise after lunch. Now, that I'm a father, the roles are changing and I'm the one sleeping after lunch. By the way, at night, in order to fall sleep, I never take phones, tablets or computers to my bedroom. Instead, I take a shortwave radio and I tune the BBC world service news (fortunately, in Spain we can hear the broadcast directed to Africa). I put a 30 minutes timer on the radio and I almost never hear it stopping, because I fall sleep before. The day that the BBC will shut the SW broadcast, I guess I will take a bluetooth headset or speaker to my bedroom, but not the iPhone. It is very important to avoid computers in the bedroom.

gurtwo 12y ago
As a spaniard myself, I can confirm this is an accurate description of what siesta looks like on most cases. Short nap on the couch after a coffee, for those who take lunch at home, or just on the weekends otherwise.
- aeire 12y ago
  hmm.. i believe this is pretty the same in Greece, at least during weekends, holidays and work-free days. In every lunch-gathering with close relatives, or close friends, at least one or two person take a short nap on the couch after the lunch, while the rest are having a relaxed and low voice chat. Usually the persons who fall asleep are males.

I don't know if it's just me but, how the hell do you nap?! I tried once, and I was still wide awake when my alarm that was supposed to wake me up from my hour long nap went off. I'd have to be really drunk, or not have slept for days in order to nap. I don't understand how people just nap on queue, I feel like I'm missing a trick here :(

Dewie 12y ago

I'm thinking of putting a mattress beneath my desk/cubicle. I have a hard time falling asleep on command or taking naps at all. Maybe properly lying down instead of lying kind of uncomfortably on the floor will help with that. This is in a university setting, so I have no managers to worry about. The only problem might be noise (I often sleep with earplugs anyway), and weird looks.

rootbear 12y ago

I have read before that drinking coffee before a short nap is a good combination. It's nice to read that someone has actually tested it. I can't always do it at work but I have used this method at home and it works well. One other suggestion I follow is that I don't take short naps lying down. That encourages my body to go into a longer, deeper sleep. I nap sitting in a comfy chair, in a quiet, dim room if possible. It's very refreshing; I'm more alert and productive for the rest of the day.

danelectro 12y ago

I support the napping for productivity without having artificial stimulants (OK, natural organic drugs) involved. The studies likely involved mostly habitual users rather than unindoctrinated subjects, but from the abstracts' documentation it is difficult to be sure. Perhaps the researchers did not recognize the distinction and just selected random participants, therefore likely to include mostly habitual users. When I was a caffeine addict (habitual user) I could also sleep after ingestion. In fact without a fix right before bedtime it was more difficult to get to sleep because nominal concentration level was unsatisfied, resulting more in agitation than identifiable craving. A nice hit would actually help me relax. I was not the only one who could relate to this as an indication of true addiction, where you need the substance just to be normal. Complete withdrawal took a few weeks (of hellish tiredness, achiness, and irritability) but after this it was even easier to more alertly conduct high-stamina activities and out-perform my still-addicted colleagues without the toxic load on my system. Sleep & nap much more productively without it after kicking the habit too. Sure can write a lot better code when drug (addiction) free as well. When I do feel it's necessary (never for marathon coding), a single cup of coffee (after I have already been awake 24hrs and need a little boost) naturally keeps my otherwise drug-free system awake for the next 24hrs easily which can be helpful for things like long-distance driving once or twice per year. As an addict I would have needed two or three times my nominal habitual doses to feel as alert on those same lonely roads. To me coding does not benefit from this type of non-stop alertness, even if you are working to exhaustion, when tiredness truly comes a plain nap is better whether it is after 6hrs, 12hrs, 20hrs, whatever, then freshly go into another session, exahustion relieved. Same with driving too, but if the schedule is too tight, a couple times a year will not make you a habitual user like everyday dosage does. I'd rather drive slow for long hours than exceed the speed limit, waste energy, and prematurely wear out my machinery. YMMV [0] but just because everybody does caffeine won't make it good for you, especially in the long run. [0] depending largely on body weight, metabolism, and dosage, and for driving, road speed

How long can coffee napping be used, and what are the after effects? The article says the test subjects used it to good effect for 24 hours. I wonder if the following day was a compete productivity waste.

duffx 12y ago

Keep in mind that after 2-3 weeks of habitual coffee drinking, your body acclimates to the effects of caffeine and you no longer receive a performance benefit. At that point all drinking coffee does for you is ward off the effects of withdrawal and return you to baseline performance levels - until the effects wear off and withdrawal kicks in again, at which point your performance is below average. Caffeine is best used strategically, which means not every day. Save it for days where you're feeling particularly low energy, or need a boost to tackle a problem you're not particularly excited about doing. That said, the half-life of caffeine is around 6 hours, which means if you have a coffee at 3pm, at 3am you still have a quarter-cup's worth of caffeine in your system, preventing you from entering deep sleep. So even then I'd keep caffeine as a first-thing-in-the-morning type of deal. Naps I'm a big fan of. I take one every day after lunch. The trick is to simply lay down and close your eyes for 20 minutes. Don't worry if you fall asleep or not - just give your eyes a rest. For the first few days/weeks, you might not fall asleep. But eventually your body grows accustomed to the ritual and it becomes easier to actually fall asleep at hat time.
