Do you sit too much?
In an editorial published in the January 2010 publication of the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences said that authorities need to highlight the dangers of sitting. ”After four hours of sitting, the body starts to send harmful signals because the genes that regulate the amount of glucose and fat in the body start to shut down.”
Tim Armstrong, a physical activity expert at the World Health Organization said that people who exercise every day—but still spend a lot of time sitting—might get more benefit if that exercise were spread across the day, rather than in a single session.
A new Australian study by Melbourne-based Baker IDI Heart and Diabetes Institute, in conjunction with health insurer Medibank Private, has alarming findings about the simple act of sitting down: It’s dangerous, particularly at work and watching TV.
The study was published in the American Heart Association Rapid Access Journal Report in January of this year. They said that the theory of sedentary lifestyle being bad for you isn’t new, but that the findings in this study are alarming.
Australian researchers tracked the lifestyle habits of 8,800 adults and found that each hour spent in front of the television daily was associated with:
An 11 percent increased risk of death from all causes.
A 9 percent increased risk of cancer death.
An 18 percent increased risk of cardiovascular disease (CVD)-related death.
Compared with people who watched less than two hours of television daily, those who watched more than four hours a day had a 46 percent higher risk of death from all causes and an 80 percent increased risk for CVD-related death.
This association held regardless of other independent and common cardiovascular disease risk factors, including smoking, high blood pressure, high blood cholesterol, unhealthy diet, excessive waist circumference, and leisure-time exercises.
Len stands—all day. There are stand-up desks. And there are pub tables. As you can see in the final photo, Len’s preference is the latter. A good choice, as he burns an extra several hundred calories per day just by taking a stand!
