Television knows no night, but people should control their screen time. As enjoyable asare a variety of programs from dramatic series to news cycles, too much television viewingtime may have adverse consequences that rival those of lack of physical activity, obesity andsmoking. Despite the advantages of television programs being transmitted around the clock, apublic health case may be made that adults as well as children need to reduce the time spent infront of the 'box'.
If used wisely, television benefits people daily. It has proved to be the most important andcherished medium for entertainment and information. For example, the 24-hour television ishelping to relieve feelings of depression during a hard day, and of loneliness during asleepless night. It is not only a powerful and effective learning tool for children but also isuseful for adults to understand the complex social aspects of communication. In a certainsense, any time wasted in enjoying TV is not actually wasted because it is exactly what is rightabout it. To tell the truth, what can be a better way to digest free time than watchingtelevision?
Sitting too long is a ubiquitous sedentary behavior, which doctors say may lead to healthrisks. According to a medical report, every hour viewed may shorten life by as much as 20 to25 minutes. If the report is reliable, anyone who spends six hours a day watching television isat risk of dying five years sooner than those who enjoy more active pastimes. The message isclear: children should limit viewing time to two hours, and adults to four hours, in order toavoid possible negative effects. That is to say, going beyond these limits is said to be harmfulto health. Even though the relationship between viewing time and life expectance is hard to becalculated, there are reasons to believe that addiction to the 24-hour television programs isanything but positive.
To conclude, the 24-hour television transmission is a positivedevelopment as long as people can be aware of possible health problems. In some countries, TV networks never sleep, but people need to rest and do physical exercises for good health.
