Sitting in front of the TV for two hours a day raises your risk of bowel cancer by 70%, scientists declare amid sharp rise in cases

  • Study looked at sedentary behaviours of nearly 90,000 US women  – Two hours a day was associated with a 70% increased risk compared to less – Findings were independent of participants weight and level of exercise

Sitting in front of the TV for as little as one hour a day can increase your risk of bowel cancer, a study has found.

Those who lazed in front of the TV for two hours a day or more had nearly a 70 per cent increased risk.

It’s the first time sedentary behaviour has been identified as a factor to explain the sharp rise in cases of bowel cancer among those under the age of 50.

International researchers said the findings stress the importance of keeping active, even though the associations were independent of a person’s weight or exercise level.

The study, led by Dr Long Nguyen at Massachusetts General Hospital and Harvard Medical School, analysed TV viewing times and other sedentary behaviours.
