*interesting healthcare fact* If you sit for more than 11 hours a day, theres a 50% chance youll die within the next 3 years For those of us who spend the majority of our working day in a desk chair, the news from health researchers is that the more time you spend sitting each day, the greater your chance of dying within the following 3 to 15 years (depending on which study you consult). In the latest study to support this claim, the sitting-equals-death threshold was 11 or more hours a day. For the age-group studied (45 years and older), those who sat 11 or more hours a day had a 40% greater chance of dying within three years, as compared to people who sat four or less hours a day. The reason sitting is dangerous involves a combination of factors. The first, and most obvious, is that the more we sit the less calories we burn and more of what we consume is stored as fat. Over time, as we’re all well aware, carrying around excess fat predisposes our bodies to a range of health problems including diabetes and heart disease. The less obvious reasons are more immediate, including a rapid drop in a circulating blood enzyme called lipase that is responsible for breaking down fat. One study puts this drop at 90% – a virtual shut down. In addition, electrical activity in our leg muscles radically decreases the longer we sit, and that means that our metabolic rate slows to a crawl, to about one calorie per minute. And one of the most dangerous outcomes of sitting for extended periods isthat our bodies become less sensitive to the insulin our pancreas is busy producing(24% less sensitive according to one study), and that skyrockets the risk of developing Type 2 diabetes. Bottom line: if your job requires sitting for long periods, you have twice the likelihood of developing cardiovascular disease than someone who doesn’t sit all day.You can offset that risk somewhat by exercising regularly, but the hours in your chair will still take a toll. Add to this that most of us also sit a fair amount when we aren’t at work, and the problem only gets worse. So what can we do about it? The most doable advice I’ve come across so far is by scheduling a “get up and walk” break every 15 to 30 minutes. Of course, this will only work if you have a job that allows you to leave your office that frequently. Even just getting up and walking around your office suite or taking a stroll to the lobby will help. This next suggestion will sound a bit odd, but another way to help offset the negatives of sitting is by fidgeting. Yes, fidgeting.Jiggling your legs, pacing while you’re on a call, getting up and circling your desk while thinking through a problem — all of these behaviors help over time. A final suggestion is a little harder to do, but if you can do it, do it — and that’s to work at a standing desk.
