    Stand Up For Your Health -- Physiologists And Microbiologists Find Link Between Sitting And Poor Health

    Physiologists And Microbiologists Find Link Between Sitting And Poor Health
    June 1, 2008 Physiologists analyzing obesity, heart disease, and diabetes found that the act of sitting shuts down the circulation of a fat-absorbing enzyme called lipase. They found that standing up engages muscles and promotes the distribution of lipase, which prompts the body to process fat and cholesterol, independent of the amount of time spent exercising. They also found that standing up uses blood glucose and may discourage the development of diabetes.
    You're probably sitting down right now. Well, by the time you're done reading this, you may see sitting in a whole new way!
    "Chair time is an insidious hazard because people haven't been told it's a hazard," Marc Hamilton, Ph.D., a professor of biomedical sciences at the University of Missouri in Columbia, told Ivanhoe.
    That's right -- the time you sit in your chair could be keeping your body's fat burning in park! More than 47 million adults in the United States have metabolic syndrome, which causes obesity, diabetes and heart disease. Biomedical researchers from the say the reason so many of us have the condition is because we sit too much!
    "The existing data, by numerous studies, are starting to show that the rates of heart disease and diabetes and obesity are doubled or sometimes even tripled in people who sit a lot," Dr. Hamilton explains. One reason, he says, is an enzyme called lipase. When it's on, fat is absorbed into the muscles, but when we sit down, lipase virtually shuts off.
    "Instead, the fat will recirculate in the blood stream and go and be stored as body fat or it can clog arteries and cause diseases," Dr. Hamilton says. And it's not a small amount of fat. Plasma samples were taken from the same person after eating the same meal. When they ate sitting down, the sample was cloudy, but when they ate while standing up, it was clear.
    "If you can perform a behavior while sitting or standing, I would choose standing," Dr. Hamilton says. That's why he swapped his desk chair for a treadmill. Not ready for that step? "You can have just as much fun watching your kids play if you're standing by the fence, next to a friend who pulls out that aluminum lawn chair and is sitting there," Dr. Hamilton advises.
    You can also limit chair time by taking frequent breaks at work to stand and walk around. Stand up while talking on the phone or even while watching TV.
    Standing also helps shrink your waistline! The average person can burn an extra 60 calories an hour just by standing! "But just avoid the chair is the simple recommendation, as much as you can," Dr. Hamilton says. That's advice worth a standing ovation!
    Another benefit to standing -- it improves your HDL or good cholesterol levels. People who sat reduced their good cholesterol levels by 22 percent!
    ABOUT TYPE I DIABETES: This is known as an autoimmune disease, because the body destroys its own cells: those that produce insulin. When all those cells have been destroyed, the symptoms of Type I diabetes appear. These include unexplained weight loss; vision problems; more frequent urination; and feeling very hungry, thirsty or tired. Among other long-term complications, Type I diabetes means there is an increased risk of kidney failure, nerve damage, heart disease and blindness.
    WHAT IS ARTERY PLAQUE: Plaque doesn't just grow on your teeth. It can also form inside your arteries -- the blood vessels that carry oxygen and blood to the heart, brain and other parts of the body. Arteries have an inner layer of muscle. When it is damaged, plaque can form, sometimes leading to a bulge in the wall of the artery. The bulges can grow big enough to cause the inner lining to rupture. The body responds by sending clotting fibers to the damaged site.
    Minerals, especially calcium, can become trapped in the net of fibers, and so can fats like cholesterol. The minerals and fats build up over time, causing the arteries to narrow. Blood can't flow so easily through the restricted arteries. The arteries can also become clogged, stopping blood flow completely.

    I agree with this... though it's like saying sugar causes cavities, sort of common sense or it should be.

      I decided to stand at work and at home as a way of upping my muscle use last week. good information here

        Ha, the article title pleases me .

        I'm one who loves to sit. Even if I have good energy and am tapping my feet and whatnot I still like to sit. But I am making an effort to stand for at least 30 minutes after eating and to get up and stretch and do some exercises once an hour if I'm sitting for long periods. Sometimes I don't always do it like if I'm deep in concentration, but it's certainly more frequent.

          Cooking is like the best activity for not sitting. Volunteer to cook 3 different dishes, and if you have a split second in between, drink water and go to the bathroom or clean! I've spent 5 hours standing without even realizing...then I sit down at the end and I feel like I just worked out!

              I wouldn't just brush this article off so easily. It is always assumed that the extent of the issue is that when people are sitting they aren't walking around and getting more exercise and thus not enabling their bodies to expend the energy that they want, but this takes it one step further suggesting impaired glucose metabolism and implications for heart disease. That's some serious shiznit.

                I didn't really see anything shocking linking sitting too much with increased heart disease. I'm sure we all agree that we aren't designed to sit all day. I would think there are other sources that inflict diabetes and heart disease (grains, sugars, PUFA's) more than this sitting too much.

                  Indeed, but anything that contributes to pathology is worth emphasizing.

                      That's it. I'm building myself a standing desk. No more f**king around.

                        Totally agree that cooking is a great way to stay on your feet (and just a great thing to do, period).

                        I had a similar reaction to Arikara6 when I read this - I spend a lot of my sitting time at a desk, so a standing desk might just be the way to go (especially since I've heard they're good for improving back pain). I think I'm going to try it out on my kitchen island for a while...

                        Also, how transgressive do you think it would be to use a standing desk at the office? I work for a large university. The office is nominally "business casual" but people wear everything from jeans to full suits. I'm a designer, so I'm allowed to be relatively eccentric, and I have plenty of really weird coworkers. But no one is "standing desk" weird. And I'm angling for a promotion...thoughts?

                          I think only a very odd person would not promote someone because she prefers to stand up at her desk.

                            Anyone catch that delightful bit of bullshit? Yes, there's fat in your bloodstream, but not big greasy chunks of it. And yes, cholesterol can accumulate in damaged arterial walls, but let's forget what causes that damage in the first place (inflammation from high blood sugar) and hint that we should reduce the healthy things that get caught there.

                              If I am 5' 11" how high should my keyboard be? I know the monitor should be at eye level without neck strain, but from you guys' experience what is the best ergonomic angle and height for typing and mouse use.
