Too much! Pupils spend four hours watching TV and surfing the Internet in summer vacation.

It is really "too much"! During the summer vacation, children and teenagers spend a lot of time watching TV and playing computer. According to the survey, children aged from1June 1998 to1/kloc-0 spend an average of about 2 hours watching TV and playing computer on weekdays, and twice as much on holidays, with an average of about 4 hours. Therefore, the National Health Bureau reminds parents to pay attention to let their children exercise more during the summer vacation to enhance their health and physique. Because proper physical activity can not only increase heart and lung health and muscle strength, enhance immunity, but also increase vitality and self-confidence, promote cognitive function and reduce depression.

Proper physical activity can not only increase heart and lung health and muscle strength, enhance immunity, but also increase vitality, self-confidence and promote cognitive function. Chen Yanfang, chief of the Community Health Department of the National Health Bureau, pointed out that the National Health Bureau conducted a national health interview survey in 1998, and investigated the health behaviors of students in senior high schools, vocational colleges and five universities in 100. The results of the survey on watching TV, playing computer or electronic games, and exercising time show that1June 1998-11year-old children spend about the average time watching TV and playing computer on weekdays.

In addition, in 100, 49.9% of high school students watch TV, play computer or play video games for more than two hours three days a week, and the proportion of boys is higher than that of girls. In 100, there are 7 1.7% high school students who don't exercise for 30 minutes a day and 3 days a week, and the proportion of girls is higher than that of boys.

In addition, the World Health Organization recommends that children and adolescents aged 5- 17 should have at least 60 minutes of moderate to intense physical activity every day, while the American Academy of Pediatrics recommends that children under 2 years old should not watch TV, and children over 2 years old should not watch screen for more than 1-2 hours every day. Studies abroad have also pointed out that the more physical activities children have every week, the less likely they are to spend more than 2 hours in front of the screen every day.

Chen Yanfang, the group leader, stressed that children and adolescents are in the growth stage. In order to maintain normal physical development, parents should encourage their children to participate in various activities, sports and housework during the summer vacation, keep enough physical activity every day, reduce the time spent watching TV, playing computers, mobile phones and playing electronic games, spend the summer vacation healthily and greet the arrival of the new semester with abundant vitality.
