Therefore, patients with liver disease should pay attention and try not to watch TV at home!
(1) the dangers of children often watching TV.
Hazard 1: Affect eyesight and hurt eyes.
Studies have shown that children's eyesight may temporarily drop by 30% after watching TV for about 5 hours. If the child's vision is impaired, it will cause irreparable loss to his future study.
Hazard 2: Affect appetite and hurt stomach.
Watching TV for too long will affect children's appetite and digestion and absorption of the stomach. When eating, the blood of the whole body is concentrated in the gastrointestinal digestive system. Watching TV at this time will make a lot of blood flow to the brain-this will reduce the gastrointestinal digestive function and even cause chronic gastrointestinal diseases due to the decrease of blood flow in the gastrointestinal area.
Hazard 3: It affects exercise and is slow to respond.
Active is a child's nature. If you sit in front of the TV all day, it will reduce your child's interest and activity opportunities and affect your child's health. Physical exercise will promote children's physical growth and development, and also make children full of keen reaction ability to the outside world. If they are inactive for a long time, they will be slow to respond.
② The harm of pregnant women watching TV.
Many people know that pregnant women should try not to watch TV because it is harmful to their babies, but what is the harm of pregnant women watching TV? Some women will spend more time watching TV to kill time because of less activity after pregnancy. In fact, this practice of pregnant women is very harmful to the fetus. RvT pregnant women network
According to the survey of nearly 700 pregnant women who are close to the screen for 20 hours a week, it is found that 20% of them have spontaneous abortion, and the survey results of pregnant women who are close to the screen for 40 hours a week show that the spontaneous abortion rate is higher.
When the TV is working, the picture tube constantly emits X-rays invisible to the naked eye. Some of these rays are emitted outward, and the impact on the fetus cannot be ignored. Pregnant women are often prone to miscarriage or premature delivery, and may also cause fetal malformation, especially the fetus of 1-3 months. If you want to watch TV sometimes, the distance between the fluorescent screens should be more than 2 meters. RvT pregnant women network

In addition, watching TV for a long time will affect the blood circulation of lower limbs, aggravate edema of lower limbs, and more easily lead to varicose veins of lower limbs; For pregnant women, the tense and thrilling scenes on TV can be called inferior sidelights, which hinder eugenics; Watching TV too late in bed hinders the sleep and rest of pregnant women, which is not good for pregnant women and fetuses.

Therefore, it is recommended that pregnant women watch less TV, otherwise it will delay the next generation for temporary entertainment, and it will be too late to regret abortion or premature birth of deformed children.
(3) excessive watching TV is harmful to one's health.
When the summer vacation comes, many primary and middle school students indulge in TV programs without restraint. However, ordinary parents only know that watching TV for a long time will affect their eyesight. In this issue, we invite experts to introduce the latest research results to readers. The purpose is to make parents understand the dangers of watching TV for a long time in order to limit their children.
Nowadays, as we all know, indulging in TV programs will affect children's learning; Watching TV at close range for a long time will reduce children's eyesight; Some violence, murder and other programs will have adverse consequences on children's physical and mental health. However, many parents still don't know the harmful consequences of watching TV excessively for their children's adulthood. Recently, a new research report in New Zealand pointed out that children and adolescents who watch TV for more than two hours every day are prone to some bad living habits, which increase the risk factors such as smoking, overweight and hypercholesterolemia and affect the health of adults.
From 197 1 to 1973, researchers studied more than 1000 children born in Dunedin, New Zealand, and followed them regularly until they were 26 years old. They made a scientific study of the follow-up records. The results show that children and adolescents watch TV for more than 2 hours every day, which is significantly related to health problems such as the increase of body mass index and cholesterol, the increase of smokers and poor cardiovascular health at the age of 26, but has nothing to do with blood pressure. After the researchers corrected for factors that might confuse these subjects in childhood, the correlation did not change.
Among all the 26-year-old adults surveyed, 65,438+07% smoked, 65,438+07% were overweight, 65,438+05% had elevated blood cholesterol, and 65,438+05% were in poor health, all of which were caused by watching TV for more than 2 hours every day in childhood.
This study has attracted the attention of relevant scholars, especially the issue that obesity is closely related to watching TV. Experts believe that although obesity is related to genetic, environmental and social psychological factors, the multifactorial nature of this problem should not be an excuse for people not to take measures to solve the problems caused by watching TV. Before the new generation will become obese, it is reasonable to restrict children from watching TV and prohibit children's food advertisements. Commenting on this study, Harvard Medical School scholars pointed out that the results of this study make the reasons for banning food advertisements to children more sufficient. In an era when the proportion of obese children has reached a critical point, food manufacturers have no right to guide children to consume high-calorie and low-quality fast food, drinks and snacks. All these will lead to excessive weight gain. Therefore, the American Academy of Pediatrics has issued a statement that direct advertising for children is deceptive in itself and only considers its own interests.
The conclusion of this study shows that watching too much TV by children and teenagers may have a far-reaching impact on their health as adults. Therefore, experts who study children's health issues advocate that parents should limit their children's time of watching TV every day to only 1-2 hours; And warned: reducing the time of watching TV should be people's priority health problem.
