Watching too much TV could make you die earlier

Bad news, couch potatoes. 

A study has found that adults who watch three or more hours of TV a day may double their risk of early death. 

The study was conducted by the American Heart Association, who studied over 13,000 university graduates from Spain. 

These subjects were about 37 years old when the study started and researchers measured three different sedentary behaviours over eight years: TV-watching, computer time and driving time. 

Computer time and driving time did not have a significant impact on a person's risk of premature death. 

Although Time magazine noted the results are still preliminary, it did make the link between long periods of TV-watching and prolonged sitting, which has also been found to be very bad for health. 

The American Heart Association recommends at least 150 minutes of moderate intensity aerobic activity or 75 minutes of vigorous aerobic activity each week.
