Australia's Heart Foundation foresees guidelines on sitting less in addition to current physical activity suggestions. (CBC)Spending more time sitting in front of the TV increases the risk of an early death from heart disease, regardless of your weight, researchers in Australia suggest.
The team followed 3,846 men and 4,954 women, average age 50, who did not have a history of cardiovascular disease.
For about seven years, researchers monitored blood pressure, cholesterol levels and TV habits.
Each hour spent sitting in front of the TV per day raised a person's risk of death from cardiovascular disease by 18 per cent and the risk of dying for all causes by 11 per cent
, David Dunstan of the Baker Heart and Diabetes Institute in Victoria and his colleagues reported in Monday's online issue of the journal Circulation, published by the American Heart Association.
