Don’t sit too long in front of the TV
Watching TV for too long puts people at just as much risk of suffering deadly blood clots as a long-haul flight, according to new research. Sitting in front of the TV for an average five or more hours a day leads to twice the risk of fatal pulmonary embolism – blood clots to the lungs – as watching under two and a half hours a day.
Researchers from Osaka University in Japan, who studied 86,000 people over 18 years, said TV viewers should stand up occasionally and drink water to avoid blood clots. A pulmonary embolism is a blockage in the pulmonary artery, which is the blood vessel that carries blood from the heart to the lungs. Up to 60,000 people die from the condition every year in Britain.
The research, presented at the European Society of Cardiology conference in London, warns that people should take the same precaution when watching television as they do when catching long-haul flights.
The rise of streaming services like Netflix and the boom in downloading entire television series – such as Breaking Bad and Game of Thrones – could add to the danger. The study found that people who watch television for more than five hours a day more than double the risk of fatal pulmonary embolism. The risk is even higher for people aged between 40 and 59, the Independent on Sunday reported.
Dr. Toru Shirakawa, who led the research by the Department of Social Medicine at Osaka University, said: ‘This is the first time a direct link between prolonged television watching and fatal pulmonary embolism has been shown.’ He said that long-haul flights were a well-known cause of the condition, but pointed out that people were more likely to regularly watch lots of television than fly.
The academic added: To prevent the occurrence of pulmonary embolism, we recommend the same preventive behaviour used against economy-class syndrome. That is, take a break, stand up, and walk around during the television viewing. Drinking water for preventing dehydration is also important.’
Pensioners watch more TV than any other age group with an average of five hours and 40 minutes a day, putting them at more risk. Professor Jeremy Pearson, associate medical director at the British Heart Foundation, said: ‘While we wouldn’t advocate a public health warning for watching television, people who spend many hours in front of the TV should consider how this might be impacting their heart health.’
Pulmonary embolism: Warning signs of a blood clot
A pulmonary embolism is a blockage in the pulmonary artery, which is the blood vessel that carries blood from the heart to the lungs. This blockage – usually a blood clot – is potentially life threatening, as it can prevent blood from reaching the lungs.
The symptoms of a pulmonary embolism can sometimes be difficult to recognise because they can vary between individuals.
But the main symptoms include:
Chest pain – a sharp, stabbing pain that may be worse when you breathe in
Shortness of breath – this can come on suddenly or develop gradually
Coughing – this is usually dry, but may include coughing up blood or mucus that contains blood
Feeling faint, dizzy or passing out
See your doctor as soon as possible if you have a combination of these symptoms.
If symptoms are particularly severe, call for an ambulance.
