One of the characteristics of television is to make time into perceptual fragments, and present information through a large number of short-term fragments, fast actions, lens switching, gradual strengthening and gradual concealment. But children love watching TV, but watching TV over time damages their health, and watch its “ten sins”!

Dr. arique Sigman, a partner of the British Psychological Association, suggested on Tuesday that children under three should not watch TV, and that older children should also be limited in the amount of time they watch TV every day. “Television is the biggest unrecognized health threat of our time and poses many health risks to children who are reluctant to go out all day long,” he said


Overtime watching TV is harmful to children’s health

Dr. Sigman analyzed and reviewed 35 academic studies on the health risks of television to children. He said the results showed a range of health risks that had not been anticipated before. Speaking at a meeting of the British Parliament, Dr. Sigman urged ministers of government departments to introduce more measures to limit the time children spend watching TV every day, so as to stop a series of health problems ranging from obesity, myopia to precocious puberty. Professor Sigman believes that children under the age of three should not watch TV at all and that parents should not put TV in their bedrooms.

Dr. Sigman’s research shows that the average British person watches TV longer than any other country in Europe, and teenagers in the UK face up to 7.5 hours of TV every day. In contrast, the British spend less time reading than any other country in Europe. Moreover, the number of obese children in the UK is also the highest in Europe.


Children of different ages have different restrictions on watching TV

Dr. Sigman recently proposed to lawmakers that a “daily intake recommendation” system similar to salt intake guidance should be set up to properly control the time of watching TV:

The time of watching TV should be limited to 30 minutes to 1 hour for children aged 3 to 7, and one hour for children aged 7 to 12;

Children between 12 and 15 years old should be limited to one and a half hours of watching TV every day;

Teenagers over 16 should be limited to two hours a day.


TV “ten crimes”

-Hormone secretion disturbed

The light from TV suppresses the production of melatonin, an important hormone.

-Decreased immune function

The decrease of melatonin may increase the chance of DNA mutation and lead to cancer.

– early maturity

Girls are now entering puberty earlier than they were in the 1950s because of their weight gain, but it may also be related to the decrease in melatonin that they often watch TV.

-Sleep disorders

Over stimulation of the sensory organs is easy to cause insomnia.

-Prone to autism

This is related to the decrease in social time caused by watching TV.

– obesity

This is because children watching TV are less active. The secretion of some hormones is affected, resulting in increased fat and appetite.

-Increased risk of heart disease

Because the rise of cholesterol and the change of hormone will affect the quality of sleep and reduce the immune ability.


Attention span is shorter and ADHD is more likely to occur.

-Affect brain development

Watching TV is different from reading. Reading can stimulate the brain, promote brain development, and promote children’s analytical thinking ability. Watching TV is a passive behavior, without such a function.

-Affect academic performance

By the age of 26, the education level of people who watch more TV is generally lower than that of people who seldom watch TV.

The negative effects of TV on children’s academic development, both physical and psychological, will inevitably affect learning. Therefore, we should strictly control the time of children’s watching TV, guide them correctly, and prevent the adverse consequences of TV.
