Limit TV time to 2 hours says researchers

According to a study by scientists at Glasgow University restricting TV watching time for adults could increase longevity. Analysis of information from 500,000 Britons aged from 37 to 73 over seven years showed that 6 per cent of all-deaths and 8 per cent of cardiovascular related deaths could be associated with too much TV watching. The study findings pointed to too much time spent watching TV resulting in less exercise and poor diet.

Dr Hamish Foster from the University of Glasgow’s Institute of Health and Wellbeing, who led the study, said: “This study adds more weight to the evidence that more time spent watching TV is likely to be detrimental to health.

“Our study suggests limiting TV time could delay or prevent a lot of adverse health. However, there is still more work to be done before we can make firm TV time recommendations. TV time is just one of a number of potentially sedentary behaviours, which also includes screen time watching videos on your phone, which may all contribute to adverse health outcomes. Also, there are many other contributory factors, such as unhealthy snacking and lower socioeconomic status, that are also strongly associated with both TV time and poor health outcomes. Further research is needed to understand all these factors and inform future advice and guidelines.”
