One in 10 cases of heart disease could be avoided if the British watch less television, a study found.
Sticking to the TV prevents people from burning calories at dinner and making fun of fatty chips and chocolate.
A Cambridge University study estimated that 11 per cent of cases of cardiovascular disease can be prevented by limiting television to less than an hour a day.
But according to Ofcom, the British watched an average of 4.5 hours a day during the Covid 2020 crisis.
dr. Youngwon Kim, of the University of Hong Kong, said: “Limiting your time watching TV could be a relatively minor change in lifestyle that could help people.”
Dr. Cambridge. Katrien Wijndaele added: “Coronary artery disease is one of the leading causes of premature death, so it’s important to find ways to help people manage their risks.”
Heart disease leads to around 64,000 deaths a year in the UK.
One of the main risk factors is not getting enough exercise and spending too much time sitting.
Smoking, high blood pressure or cholesterol and diabetes can also damage blood vessels.
The survey of 370,000 people in the UK found that watching TV for four hours or more a day led to increased risk of illness.
Reducing it to less than an hour reduced the danger by 16 percent, while between two and four hours, a six percent reduction was achieved.
In the journal BMC Medicine, Dr. Kim wrote that watching TV after meals meant that fat and sugar from the meal entered the bloodstream instead of acclimating to energy.
Couch potatoes are also more likely to eat junk food.
Scientists find no higher risk of people spending free time on a computer and say they tend to get up and move more.
Chloe MacArthur, of the British Heart Foundation, said: “We know from decades of research that a sedentary lifestyle can lead to health problems later in life.
“If you are tempted to watch another episode, try getting up and stretching or going on an evening outing.
“Stopping evening snacks and making sure you eat a healthy, balanced diet can also boost your heart health.”
