        According to a paper published in the European Journal of Preventive Cardiology on the 20th, people who watch TV for four or more hours a day have a 35 percent higher risk of developing blood clots。

      In this study, scientists investigated the relationship between watching TV and venous thromboembolism (VTE)。VTE includes pulmonary embolism and deep vein thrombosis。

      The researchers used meta-analyses to combine the results of studies relevant to the topic to reach more precise and reliable conclusions。The analysis included three studies with a total of 131,421 participants aged 40 years and older who did not have a pre-existing VTE。Using questionnaires to assess TV time, participants were divided into those who watched TV for a long time (at least 4 hours per day) and those who never or rarely watched TV (less than 2 hours per day).5小时)。

      The average follow-up time of the three studies ranged from 5.1年到19.8-year inequality。During that time, 964 of the participants developed VTE。The researchers found that people who watched TV for a long time were 1 percent more likely to develop VTE than people who never or rarely watched TV.35倍。

      Dr Seto Cunusor, lead author of the paper from the University of Bristol, said: "The findings suggest that prolonged TV viewing is a dangerous activity that can lead to the formation of blood clots, regardless of physical activity, body mass index, age and gender。If you want to watch TV for a long time, you need to learn to take breaks, such as standing every 30 minutes to stretch, you can also ride a spinning bike, and avoid eating unhealthy snacks while watching TV。
