Are you sitting comfortably? Well, you had better stand up. Sitting is the latest health hazard, according to a study published this week, showing that being sedentary for hours at a time increases your risk of diabetes, heart disease and premature death.
The research, from the University of Leicester and published in the journal Diabetologia, combined the results of 18 studies and nearly 800,000 people. It found that prolonged sitting doubled the risk of diabetes and heart disease, and that the risk wasn't eliminated for those people who took regular exercise. Sitting is a low energy activity and it may be risky because it makes our bodies think we are in energy storage mode. This makes our bodies resistant to insulin (which mops up glucose), increasing the level of glucose in the blood and reducing levels of good cholesterols while increasing levels of bad ones. All of these changes increase the risk of obesity, diabetes and heart disease.
