Sitting, even after workout, can cut lifespan

A new study debunks the theory that an hour of exercise a day is all you need to live a long life. Turns out, people who spend more time sitting during their leisure time have an increased risk of death, regardless of daily exercise.

American Cancer Society researchers tracked the activity levels and death rates in more than 123,000 healthy men and women for 13 years. They found women who spend over six hours a day sitting during leisure time (watching TV, playing games, surfing the web, reading) were 40 percent more likely to die sooner than women who spend less than three hours sitting. Men who spend more time sitting have a 20 percent increased risk of death. Essentially, those who sit less, live a longer life than those who don't.

Several factors come into play when figuring out “why” sitting may take years off your life.

The first may seem like common sense. The more time you spend sitting, the more likely you are to passively eat snacks or consume high calories drinks resulting in unhealthy weight gain. But this isn’t always the case. Sedentary obese and normal weight Americans had similar increased risk of death in the study.

Prolonged time sitting suppresses your immune system, which may increase the risk of cancer and other diseases. And your blood isn’t circulating as it should when you’re sedentary for long periods of time. When blood doesn’t flow thru your veins up to your heart, it could lead to dangerous blood clot. It also has metabolic consequences – increasing your resting blood pressure and cholesterol levels. Researchers say the metabolic effect may explain why the association was strongest for cardiovascular disease mortality in the study.

The study, published in the American Journal of Epidemology suggests, “public health guidelines should be refined to include reducing time spent sitting in addition to promoting physical activity.”

So as you keep your brain stimulated with your smart phones, video games and gadgets, wireless apps and paperless books – walk around or stand up while playing your favorite game. You may add years to your life.

      I'm an IT guy – aging. I've been working with a raised work surface at my job for almost 2 years. I can't stand to sit anymore (pun not intended) as it causes much pain by the end of the day. I had the maintenance crew come in and raise one of my two platforms to a level where I can stand with my notebook pc and work. I keep a foot rest under that platform and simply switch feet back and forth – much like a foot rail in a bar. It takes some getting used to but after a couple of weeks you'll find standing is preferred. I can always move my notebook over to the other surface if I get tired of standing and sit for a little while. A perfect, apparently very healthy, work environment.

      Jeez. Just the sort of thing a person who is wheelchair-bound wants to hear. How do you propose, good Dr; that a woman who is unable to stand, let alone walk, spend *any* time on her feet? Seems like all I'm reading these days is concerning good health is eat right and walk, walk, walk! But when it comes to those of us strapped into a wheelchair for the next 20-30 yrs of our life, *no one* has any answers or recommendations for us...

I'm on EBSCO now searching through the volumes. A professional article covering the academic press should absolutely provide information to easily track down the original source. This is SLOPPY!

      @ Mikey:

      Yeah, but kids have much longer class times than they did 20-30 years ago, and not many walk/ride their bikes to school anymore. Busing kids all over a city also counts as "seat time". Plus, phys ed isn't as rigorous as it used to be. Combine that with being so drained when they get home from school, and who wouldn't want to sit around and play Xbox360?

      Absolutely. Do not enjoy the forced sedentary position- speaks to the ethos of a bygone era. Much of my postgrad learning has occurred in an active setting- outside, or in a standing position. The nature of learning is shifting, it will be interesting, as in so many other things happening today, to see how long it takes the traditional model to catch up.

      "40 percent more likely to die sooner" than a certain cohort of the population (6 hrs women are 40% more likely to die by that age than <3 hrs women, but you have to specify an age. It isn't going to be 40 percent more likely by ANY age–age 15, 50, 65, 110. Of course, article doesn't say which age it is, so we're left with a headline that doesn't make any sense.

      "60 percent less likely to live longer" doesn't make any more sense mathematically than "40 percent more likely to die sooner." You can be 60 percent less likely to reach a certain age–which has to be specified–but not just 60 percent less likely to live longer than another group. "Less likely to live longer" and "more likely to die sooner" are just not actual mathematical/statistical concepts.

      Statistics literacy to the rescue for all the hacky sack majors out there! 40% more likely to die means this: If you pick two dead people at random, one a sitter, the other a stander, there is a 58.3% chance that the longer lived of the two was the stander. Conversely, there is a 41.7% chance that the longer lived of the two was the sitter (58.3/41.7 ~= 1.4). Hope that helped.

      But the stats mean nothing unless we know how much of a difference that life expectancy is. meaning, am I dying 3 years earlier? 10? 20? if its just 3...eh, im not that worried. if it's 20...i'm worried.

      "Thru" is a perfectly acceptable (albeit informal) variant of "through" according to http://www.dictionary.com, Merriam Webster online dictionary, and other modernized grammar sources (I looked them up because I, too was skeptical at first). And since this is a BLOG, it is very appropriate. Before slamming the article, do some research for yourself. The writer obviously did. And Jaque, if you think anyone at CNN cares that you're changing your home page to newyorktimes.com then you have much bigger issues to deal with than the word "thru." I'm sure NYT will be happy to have their 10th reader this year, though.

      @Mr. Deltoid – The NY Times is third in total circulation in the US. If you bother to read it, you'll note the quality of writing and investigative journalism is far better than most other news sources. I, for one, have always appreciated the fact that the editors publish a "corrections" section each day; in which they note any reporting errors from previous editions. Every news source makes mistakes, the NYTimes is one of the few that will so openly admit to and correct those mistakes. If I want to know how Lindsay Lohan is doing in jail...I'll check CNN.com. If I want real news, with some measure of substance and journalistic integrity; I go to the NY Times. No offense to CNN; they just have a different target market.

      "Mr. Deltoid"– Just because 'thru' is a real word that exists in the dictionary doesn't mean that it should be used in all settings. When McDonald's has a 'drive-thru' I am not particularly bothered by use of the more informal version. In a professional news article, it is unacceptable to use "thru" when the more appropriate "through" is available. In formal writing, you are not supposed to use abbreviations (unless, for example, a company's name is an abbreviation. Even then you are usually supposed to write out the full name at least once) and I believe this counts as an abbreviation. Even if you disagree, your argument of "OH WELL IT'S IN THE DICTIONARY!!!1!11" Doesn't make any sense. There are quite a number of words–(slang words, profane words, etc.) that are listed in the dictionary but should not be found in professional writing, such as news articles, barring a certain context that demands them.

      Also, seeing "thru" as a sloppy typo when there have been a fair number of other typos/grammatical errors above it is a perfectly reasonable response. Get off your high horse and stop being a jerk.

    Only in 2010 would this be considered some kind of health information breakthrough.
    There didn't need to be a single dime spent for a study like this. If you lead a sedentary lifestyle, you're going to be unhealthy.
    Period. And if you're unhealthy, you will die much sooner than someone who is, barring accidental deaths.

    But look at our nation currently: Obesity is rampant, people are more sedentary than they've ever been. We make our livings by sitting on our butts all day. We don't exercise and eat fast food most of the time since mom isn't home to cook for anyone anymore.
    We've brought a world of pain upon ourselves as Americans and it gets worse with ever passing year. Fast food, exposure to unnatural chemicals and food loaded with pesticides. Nobody gets enough sleep, everyone is on an antidepressant, work means sitting around for 8 hours and everyone is too tired to go to the gym afterward for some reason.
    If this doesn't change, we won't be around much longer to fix this nation. It doesn't matter how good your health care is or how much access you have to it if you're insistent upon killing yourself slowly. The doctors can only do so much to keep us going. The rest is up to us.

      Most of what you say is correct, though some parents who stay at home serve fast food to their kids, so it's not an issue of "mothers," or whether or not they work. Yes, many people use antidepressants, antianxiolytics (not sure my spelling there and I"m fighting my OCD urge to look it up) and alcohol or other drugs to numb things, but the rest of what you say is right on. Your IQ points and consciousness are up there. As for one who responded negatively to you, there is recent research that people who don't know don't have the intelligence to know they don't know. In law school, when I thought an exam was tough and I figured I flunked, the "C" students thought it was easy, and then I would get "top paper." Yes, we are in trouble.

      Just so you know, obesity is a world-wide epidemic. Check the WHO web site. The people of Polynesia are far fatter than Americans over all. Americans are the fattest in the developed world, but the Brits, Mexicans, Slovaks and Greeks are right behind us. I know they like to preach at Americans, but "We're not as fat as you" is not really a very good defense. They are rapidly catching up.

      Yankee Fan – I wont circle a parking lot for a good space, but I prefer to find one closer to the front when going to the gym for one reason – depending on the workout I do, sometimes it hurts or is hard to walk. Some of the times my legs are so quivery it's an issue to walk much, so I like to lessen how far I have to walk immediately after a workout. I don't really think this is a problem, although I'm sure some people do it out of laziness as you suggest.

    My mother exercised very little and sits most of the day. She will turn 90 in October. I wonder how many more years would have been added to her life if she had been more active?

      My mother is turning 91 and has spent most of her life sitting. Her sisters - same story. My mother smoked filterless cigarettes, ate red meat about 5 times a week and weighed too much until very recently. She is mentally sharp as a tack but I consider hers a wasted life - no adventure, no fun, no friends, no participation in social organizaitons or charities. Perfect health, she even has all her teeth, but all she ever does is sit and watch TV A totally vicarious life. No kind of mother to me or grandmother to my kid at all. Oh well, the luck of the draw.

    Was this written by an eighth grader? Is this what passes for medical news at CNN?

    "Prolonged time sitting suppresses your immune system, which may increase the risk of cancer and other diseases." Really? Perhaps we should prescribe long periods of sitting for organ transplant recipients, rather than costly immunosuppressant drugs. I challenge the author to present a single randomized controlled study that investigated the effects of sitting on immune system function.

    "And your blood isn’t circulating as it should when you’re sedentary for long periods of time. When blood doesn’t flow thru your veins up to your heart, it could lead to dangerous blood clot." How is it that the blood isn't circulating as it should? Is the sitting individual still breathing? Are they maintaining their body temperature? Are they still metabolically active? If they're alive, the blood is flowing "as it should". If the blood isn't flowing "thru" the veins, where does the author propose it has gone?

    It is possible to explain physiology in lay terms without oversimplification to the point of inaccuracy.

      Abe: You are so confident that there is no physiologic explanation for a correlation that has just been proven. You scoff at the statement that slow flowing blood could increase the risk of cancer. Well let me explain it to you, although I already did elsewhere in this blog, your utter defiant arrogance tempts me to repeat myself. 1. when blood loses it's motion, especially in veins, which often have valves, it causes "platelet activation" which is an extremely complex cascade of chemical events involving numerous cell lines and cytokines as well as vascular permeability factors which are helpful in wound healing 2. the cytokines from platelets, most notably IL-2, IL-12 and adhesion molecules such as CD-40 (Avandia) are able to modulate the immune response to down regulate, or conversely, upregulate via low levels the important effector systems used in killing cancer. These systems are known as the TH-2 or TH-1 immune arms. 3. The relative proportions of these arms determine the cytotoxic strength necessary for the cancer killing function 4. Modern research on cancer therapy have tried immunization modalities attempting to enhance this but have failed because of the lack of "co-expressed" molecules necessary for this immune induction. 5. Yes, activated platelets when given in transfusion cause immunosuppression and promotion of the very cancer for which the platelets are given as treatment of (chemo causes thrombocytopenia). This is a tremendously unrecognized problem in platelet manufacturing, but could be used experimentally to treat graft rejecction. 6. In fact, it is very easy to do a literature search and find that many diseases (risk of stroke and MI, multiple sclerosis, Crohn's disease, IBD) have as a presenting laboratory finding, circulating activated platelets (measured by CD antigen expression). This is NOT a routine laboratory test but if a manual differential is done on a CBC, you will see "platelet clumps" in many cases. SO THERE IS THE RESEARCH DELIVERED RIGHT TO YOU. FROM NOW ON YOU SHOULD PROBABLY HIT THE JOURNALS SINCE YOU ARE SO KNOWLEDGEABLE ABOUT THE CURRENT STATE OF MEDICAL RESEARCH.

    I visited a physician at a medical clinic which is part of a large group health organization. Before my consultation with him, I overheard he and a colleague vehemently agree that the 'new money saving tactic' put forth by the administration/owners
    was absurd. I questioned him about what I had overheard. He mentioned that all the physicians in this small clinic were now required to wear pedometers (for a designated amount of time) to see how many steps could be eliminated in their rounds. He said some physicians had to move/trade their offices a few feet down the hall after the pedometer results. So much for 'I like to move it move it...I like to move it move it...I like to move it...move it!!

      Right! It's our philosophy that is killing us. We avoid stairs. We avoid bending over, making an "extra" trip down the hall, or an extra visit next door. We think economy as if we would melt to do something physical. We hire people do pull the weeds and scoops the snow. What we need to change is our thinking. When I shovel the garden, yes it's work, but I say to myself, "it's good for my heart that I shovel this dirt". And then, we wear shoes to work than no earthly soul could walk in. Those shoes cause more than bad feet, they cause bad health from inactivity. YAY, to the doctors at your clinic who saw the fatal flaw in the company productivity plan. They see the writing on the wall.

      As a foreign language teacher, I know that communication is the goal of speaking and that the world will not fall apart if a kid makes a grammatical or spelling error. I do, however, have to point out that our disdain for grammar and proper writing are troubling. It's not the bad grammer, per se, it's the lack of caring. People do not take time write anything well, much less edit what they have written. Language is like an ax. If we let the ax become dull, we will have to work twice as hard to achieve the same effect. While the country may not fall apart because of it, the culture will still suffer. Where are the Hemmingways of this generation, who revolutionize the art? They don't exist. Innovation in literature today means nothing more than proving that you can smut.

    Oh who cares. No study can pull everyone of the population into the same sample to determine anything of value. I highly doubt that this study, while it may have some merit, is worthless. Look at history and people have been sitting for extended hours for thousands of years. This study is but one of thousands of possibilities in which there could be thousands of different possibilities affecting an outcome. If anyone believes this crap, then you need a life.

      You think this article is stupid because you lack the ability to perform basic math (that I learned in kindergarten). Work 8 hours. Commute 2 hours. Sleep 8 hours. That is 18 hours, leaving 6 hours of leisure time. It is, as the article (that you did not read) states: LEISURE TIME. The point of the article is to tell you about how your decisions impact your health. You should expect your parents, your therapist, or your babysitter to map out your daily to-do list, not CNN.

    The more medical news I read, the more depressed I get. Much of the advice that comes down the pipe is inapplicable to the lifestyle that many of us have been living for most of our lives. This particular piece is an example of a behavior that I cannot possible change without going into an entire different field of work, as I currently sit at a desk in front of a computer for much of the day. My employer is unlikely to change the way that they operate in the near future, so, as it is, I am rather stuck in (forgive the pun). This piece follows on a spate of articles (in different mainstream publication) that I have recently read that address the hazards of certain behaviors, most of which are "uniquely" American. An example might be; "Why the French live longer and are happier" or "The key to a long life is an Asian diet and spiritual outlook", or "Dark winters are bad for your psychology". I am not questioning the validity nor the benefits of these studies or these behaviors, but rather how realistic they are for the lions share of the people who are exposed to this particular or to other general health advice columns. Perhaps it is a good reason to be depressed, but I would prefer some advice that I could really use.
