Children and watching TV

Watching television is a major activity that influence on children and adolescents. Children

in the United States average watch and three to four hours a day. By the time of high school

graduation, they will have spent more time watching television than they have in the classroom.

Children who watch a lot of television are likely to: have lower grades in school, read fewer books,

exercise less, be overweight. Time spent watching television takes away from important activities

such as reading, school work, playing, exercise, family interaction, and social development.

Children also learn information from television that may be inappropriate or incorrect. They often

cannot tell the difference between the fantasies presented on television and reality. They are

influenced by the thousands of commercials seen each year, many of which are for alcohol, junk

foods, and toys. Parents can help by doing the following: don’t allow children to watch long blocks

of TV, but help them select individual programs. Choose shows that meet the developmental needs

of your child. Children’s shows on public TV are appropriate. Set certain periods when the

television will be off. Study times are for learning, not for sitting in front of the TV. Make TV

viewing an active process for child and parents!
