Remaining seated at a place for extended periods is as bad for health as smoking or over exposure to the sun, say scientists.
London, November 9 : Remaining seated at a place for extended periods is as bad for health as smoking or over exposure to the sun, say scientists.
Professor Marc Hamilton of the University of Missouri says that people who have to remain seated at their desks for hours in their workplaces, and then place themselves in front of the television after reaching home, are increasing their chances of heart disease, Type 2 diabetes and obesity.
"The dire concern for the future may rest with growing numbers unaware of the potential insidious dangers of sitting too much. These studies demonstrate a significant impact of inactivity on a par with smoking," the Daily Mail quoted him as writing in the medical journal Diabetes.
"I view exposure to sitting...like an oncologist views exposure to unnecessary sunlight," he wrote in the journal.
In another study, conducted at the International Diabetes Institute in Melbourne, it has been found that even two hours of exercise a day will not compensate for "spending 22 hours sitting on your rear end".
"People who break up their sitting time - walking to a colleague rather than emailing him, for instance - have a lower risk of diabetes," the newspaper quoted Professor David Dunstan as telling Australian Doctor magazine.
