Australia, a study found that in front of the television to spend 1 hour each time may cause an increased risk of cancer by 9%, risk of death from cardiovascular disease 18%. The researchers conducted a six-year follow-up investigation of the 8800 adults with television viewing habits and found that 4 hours a day watching television people the risk of suffering from heart disease is 80% higher than people watching TV less than two hours a day.

Some people in order to avoid a bad mood, afraid to face the problem so they watch television as outlet. However, after the television was turned off, the hypnotic state will be lifted, the original trouble reproduced, then people were more easily bored, unhappy, irritable, without vitality, and even unable to concentrate on the spirit. The University of Maryland scientists surveyed that the longer people watch television the less happy people are. While those with more frequent social activity will be happier. Swiss scientists have also found that people with less than 1.5 hours watching television every day, their life satisfaction is higher than others.
TV may also become sources of air pollution.
