Exercising (moderate physical activity) for 2-2.5 hours per week leads to a 20% reduction in all-cause mortality (not to mention its many other benefits). Exerc

• pdxandi 10y ago
  Anyone who believes they can bathe instead of exercise is probably not exercising to begin with. I doubt this study would result in reduced exercise. But I could be wrong.
  • mulmen 10y ago
    It does help to perpetuate a myth that there are alternatives to exercise which could enter in to a persons decision to exercise or not, even if they decide to do something else with their time.
    • danielweber 10y ago
      Every generation has to create its effort-free alternative to exercise, whether it's electrodes you attach to your abs or standing there while a vibrating belt shakes your body. Even George Jetson would sit around while the computer exercised for him, so I guess we know what's coming in the future.

        Crippling socialized medical costs as the obesity rate skyrockets. :-/
        • sqeaky 10y ago
          Healthy people are more expensive. People who don't exercise simply die young (in their 50s and 60s) and people who are healthy can cling on for decades fully utilizing the range of expensive treatments.
          • mulmen 10y ago
            Does this account for the additional value a longer life may bring to society? A healthy person could stay in the workforce longer for example.

                If the economy's failing to engage with everyone, the answer is a less dysfunctional economy, not death camps.

              No not at all, just raw expense.
          • passive 10y ago
            Source? My understanding is that particularly in the US, we can keep unhealthy people going for a very long time, for a lot of $$$.
            • sqeaky 10y ago
              My source was the freakonomics podcasts. I would agree that a billionaire with predictable medical expenses will more options than a person in any sort of health and likely live longer. Most people in bad health don't have unlimited money thought (simply because most people don't have unlimited money).
• nsxwolf 10y ago
  I'm already not exercising, so adding a bath sounds like it would be better than nothing. But honestly, I doubt I'd have the willpower to go to the trouble of bathing for an hour each day either.
  • sjg007 10y ago
    If you want to exercise I would suggest taking a fitness class like ripped. It's one hour long and you can modulate your intensity.
  • danielweber 10y ago
    Put your tablet in a ziploc bag and it's easy to spend an hour in the tub.
• Raknarg 10y ago
  Hot baths are effective, but mostly in conjunction with actual excersise as well (pros, especially ones who are involved in very heavy lifting, regular have hot/cold post-workout baths). This article is very sadly misleading.
  • Nomentatus 10y ago
    I would be interested in any bibliography you can supply regarding this interaction, since I'm currently interested in interventions (including but not limited to heat) that affect extracellular bacterial populations; and this could contradict some other evidence. (There is of course a lot of literature on heat-related illness and deaths during sports and exercise - so much so that it makes it hard to search pubmed for articles concerning the interaction you've pointed to.)
• bitL 10y ago
  As somebody that exercises a lot (HIIT, cycling up hills, double black diamond skiing, tennis, lifting), I find longer stays in saunas/spas (>1h in "hot" overall, <15min/hot session, 1min/cold session) very beneficial as well, giving me a great feeling of well-being and clear mind, especially in winter (combined with D + Magnesium etc.), so I wouldn't be surprised if it had a positive long-term effect as well. I also look 15 years younger I am told, but that might be partially from being an electronic music composer ;-)
  • it_learnses 10y ago
    what do you take magnesium for?
    • bitL 10y ago
      My doc told me to always take magnesium if I take vitamin D. I've just found an article about why to do it: http://www.easy-immune-health.com/magnesium-and-vitamin-d.html http://www.easy-immune-health.com/magnesium-and-vitamin-d.ht... Seems like magnesium is needed to convert D to its active form.

        • passive 10y ago
          Fascinating. Maybe I'm misinterpreting your units, but I have no related health condition (other than living in Canada), and I take 3x1000 every day (in months with an R in them). Maybe you're somewhere particularly sunny?
• paulcole 10y ago
  I see something similar in every article about some % of marathon runners who have heart problems. So many people read that and say, "Glad I don't run at all."
• koreyb 10y ago
  Upvoted for gainz. Also here is a good hyperthermic conditioning article Dr. Rhonda Patrick/Tim Ferriss put together http://tim.blog/2014/04/10/saunas-hyperthermic-conditioning-2/ http://tim.blog/2014/04/10/saunas-hyperthermic-conditioning-... Increased endurance, increased muscle hypertrophy and positive brain effects.
• QSIITurbo 10y ago
  I really don't understand those numbers. Surely mortality is 100% regardless of exercise. How was the study designed? So I read the study for fun and the non-adjusted rates are 3.84% death rate (cohort study) in no exercise vs. 2.35% in 1-30 minutes and 2.08% in more. And that's not adjusted for pre-existing conditions if I understood correctly. So meh. Even though 20% and 20% sounds really great!
• capkutay 10y ago
  > Articles like this are probably causing harm to the people that read them by discouraging them from exercise [conjecture] I know people who gleefully say 'ice cream burns calories!' while scarfing down a huge portion of desert. It's thanks to these fantasy articles where doing something easy or damaging is the same as exercising or eating healthy.
  • Nomentatus 10y ago
    If one assumes the article is false - but in any case I can assure you that excuses not to exercise aren't rare or hard to find. I'm using one right now!
    • mathgeek 10y ago
      > excuses not to exercise aren't rare or hard to find I feel like many fad diets fit the bill here. It's easy to take something that is healthy for you (eating well) and sell it as an alternative to exercise, when the latter is complementary to the former.
• zeteo 10y ago
  > Exercising (moderate physical activity) for 2-2.5 hours per week leads to a 20% reduction in all-cause mortality (not to mention its many other benefits). Exercising for an additional 5.5 hours leads to another 20% reduction. With a very important caveat in the report: > Because all of the studies in the evidence base were observational epidemiologic studies with no randomized controlled trials, the data cannot prove causality of effect. People who don't feel that great when they exercise (despite everyone urging them to exercise) are probably not in the best health. The pervasive advice to exercise more will by itself confound the studies, because healthier people will tend to self-select into the "exercise" group.
  • QSIITurbo 10y ago
    Yeah, it has its weaknesses and also from my comment below: "So I read the study for fun and the non-adjusted rates are 3.84% death rate (cohort study) in no exercise vs. 2.35% in 1-30 minutes and 2.08% in more. And that's not adjusted for pre-existing conditions if I understood correctly. So meh. Even though 20% and 20% sounds really great!" I didn't find anything there for longer periods of time but odds ratio is not a great indicator if your base chance of dying is already really low. Or maybe spend the whole week exercising to squeeze that last 0.1% out of your chance of dying.
    • ramblerman 10y ago
      3.84% to 2.08% is a 45% reduction in the amount of people that died. I don't understand your point, there is no obfuscation here, that's just how percentages work.
      • QSIITurbo 10y ago
        Um, no. 3.84% to 2.08% being an approx 40% reduction is exactly what is being avoided currently in research since its reduction of less than 2 percentage units. Imagine a medication that has a "20% and 40% reduction in mortality": You'd have to have more than 150 people treated to the max to save one person vs other cases (more than 75 to save vs no medication). Not 5 as your percentage implies. Not very efficient way to spend money if you ask me.
• Nomentatus 10y ago
  Actually 20% is dwarfed by other interventions. "Swedish study demonstrated that over a 20- year period, women who avoided the sun were TWICE AS LIKELY TO DIE OF ANY CAUSE, as women who were sun-seekers" referring to: Lindqvist PG, Epstein E, Nielsen K, Landin-Olsson M, Ingvar C, Olsson H.

  • timthelion 10y ago
    but couldn't that be because people who are more stressed are more likely to be photosensitive? Photo-phobia is a symptom of many severe diseases...
    • Nomentatus 10y ago
      Stress and MCAS often do correlate with photosensitivity, and if you have MCAS all your allergy-like reactions are going to be increased by stress, true. I've found that if my exposure to sunlight is very regular I do pretty well, though. Of course, if stress leads you to take tricyclics, they can cause photosensitivity as well. I would not discount the possibility that regular sun exposure reduces stress by boosting the immune system (not just by Vitamin D) however: https://www.labroots.com/trending/health-and-medicine/4846/boost-immune-system-extra-dose-sunlight https://www.labroots.com/trending/health-and-medicine/4846/b...
• summarite 10y ago
  Not sure you read the article, the last paragraph makes clear that they hope this will help people that are unable to exercise. I guess they are thinking of the elderly or similar. Of course people will interpret it as they wish but this is interesting research, not "vaccines-cause-x" type of research. For those looking for excuses I'm sure they can find plenty of others already.
• krrrh 10y ago
  This 2015 study on sauna use seems to point to something going on. There's a lot of speculation about whether heat shock proteins play a similar role in both hyperthermic conditioning and exercise (perhaps a form of hyperthermic conditioning in its own right). Scientists sometimes refer to sauna as "exercise mimicking". https://www.sciencedaily.com/releases/2015/02/150223122602.htm https://www.sciencedaily.com/releases/2015/02/150223122602.h... > For all-cause mortality, sauna bathing 2 to 3 times per week was associated with a 24 percent lower risk and 4 to 7 times per week with a 40 percent reduction in risk compared to only one sauna session per week. I got the reference from Rhonda Patrick who did a summary of this any other research here: https://www.youtube.com/watch?v=eWKBsh7YTXQ https://www.youtube.com/watch?v=eWKBsh7YTXQ A combination of exercise and heat-stress is almost certainly best, but there is probably significant overlap in effect.
  • summarite 10y ago
    I'm wondering how good/bad the combination is (think"hot yoga"), or if too much stress on cells/heart is simply too much.
    • krrrh 10y ago
      It's a good question. I've seen some studies that show better recovery from exercise if it is followed by a steam or sauna. I don't think we know enough to determine what the dose-response curve looks like. Related: the science is far from complete on cold exposure, but cryotherapy (cold air or ice baths) seems to enhance recovery for endurance training, but it strangely reduces progress in strength training, at least if it is done immediately following exercise. There is speculation that cold exposure reduces the post-exercise inflammation response enough to limit the body's repair response. This might not be the case if you do cold exposure outside of the post-exercise window (but this hasn't been studied afaik). Once again all credit to Rhonda Patrick who covers this in one of her videos on cryotherapy.

  • pvdebbe 10y ago
    With "research" like "a glass of red equals to 30 minutes of exercise" and "beer may be the best recovery drink after physical activity" I think I have my exercise program in place!

  Exercise as a gain reminds me of indoor plumbing: Indoor plumbing is perhaps responsible for a larger gain in life expectancy and preventive health than almost any other medical innovation in the history of mankind (also conjecture ;) ).
