TV has now become a must-have casual "tool" for every household. Whether it is an adult or a child, as long as it is idle, it will inevitably turn on the TV and hold a remote control board to watch what you like and find interesting.
Especially children, the children's channel of all kinds of interesting programs and animation love to the extreme, as long as there are these programs, they can sit for almost a whole day.
Although we know that letting children watch TV for a long time is unfavorable for health (most importantly, fears affect the undeveloped eyes). But many times, many parents have to do their own thing because of their own, or think that these programs have a certain educational function. So I feel that letting children watch TV is not a bad thing.
However, in France, it is illegal to let children before the age of 3 watch TV. Because watching TV too early, there will be a series of health threats, especially to the brain, which will cause irreversible damage.
The threat of watching television too early and long
1
Sleep well, not long
Melatonin is closely related to the quality of sleep. It also has a non-negligible effect on adolescent development. As we all know, infants and young children are long in sleep. Studies have found that watching television for a long time can inhibit the secretion of melatonin. If you do not watch for 1 week, the melatonin level in your child can rise by 30%.
2
Restricted development of the brain and nervous system
Watching television is different from reading books. The latter can promote development and improve children's analytical thinking skills. Watching TV is a passive behavior that will hinder children from experiencing the real world and limit their imagination.
Before the age of 3, brain development should complete about 80%. Watching TV regularly slows brain development and this effect is irreversible.
3
More vulnerable to cardiovascular disease
A study published this summer by the University of Sydney, Australia, states that among the 290 15-year-old boys interviewed, children who watch TV or play computer for more than two hours each day have blood markers that indicate the risk of coronary heart disease. Greatly increased.
4
Impatient and difficult to make friends
Researchers have observed for a long time that children who watch TV regularly are more impatient and nervous. Watching television is very unfavorable for social communication and for people.
How to guide children properly to watch TV
1
Choose a program for kids
Each television program has its own relatively fixed audience, just as each book has its own readership. Not all shows are good for the child's growth. Not all shows are suitable for the child's age characteristics, just as not all books are good for writing.
Parents can try to select the program that suits their child's age characteristics so that they can see it. In this way, the child can achieve the greatest gain in the smallest unit of time. First of all, parents must look at every television program they like to watch for several times. Don't be too arbitrarily determined that cartoons are necessarily liked by children.
2
Control boot time
Children are generally nervous because of their homework. Only when they have dinner, they may have time to read news or sports and other programs. Next, they should silence or shut down the TV.
Before the age of seven, children should not watch television for more than half an hour.
Do not exceed 1 hour for children aged 7-9, and do not exceed 1.5 hours for children aged 10-12;
Students aged 13-15 should not exceed 2 hours.
3
Keep a healthy attitude while watching TV
Pay attention to eye health when watching TV
The angle and distance of the TV should be appropriate and should be kept at a certain distance from the TV. Normally 2 to 2 and a half meters are suitable. If the distance is too close, the burden of the ciliary muscle to adjust the lens in the eye will increase, and for a long time, it will cause myopia. Occurrence of the eye. Do not watch TV too long.
Watch seated posture while watching TV
When you watch TV, you should also pay attention to the posture of sitting: Watching TV on the sofa, or looking at the posture of the television when you are watching TV may cause bending of the spine.
Doing some minor activities after watching TV
After watching TV, it is best to do some minor activities and then wash and sleep.
