Everyone has heard of addictions to drugs , cigarettes , alcohol , and even gambling. But can people become addicted to television？ If so , how can an addiction to television damage a person life？
B
It's very easy to understand how an addiction to cigarettes , drugs , or alcohol can be very damaging to a person life. Cigarettes can cause illnesses like cancer and emphysema ,a lung disease that makes it difficult to breathe. In addition to being bad for your health ,alcohol and drugs can impair your ability to think clearly and behave responsibly. These substances can cause your life to slowly fall apart. In the worst cases ,alcohol and drug addicts can lose their friends , families , jobs , and homes.
C
But how can watching too much television be harmful to your life and health？ One way is that it can start a cycle of bad feelings. According to one study , people who watch the most TV already suffer from anxiety or loneliness. Watching TV makes them feel relaxed and helps them forget about their feelings for a while. But the study found that while people did relax while watching television , the feelings of relaxation disappeared after they stopped watching , and the people felt worse than they did when they started watching TV. Therefore , they wanted to watch more television so they could continue to forget their bad feelings. All this TV watching kept them from doing things that could actually make them feel better , like exercising ,participating in hobbies , reading ,or spending time with friends and family.
D
Another way TV watching can be harmful is , like the addictions mentioned above , TV can cause you to neglect your life. The more you watch , the more you want to watch , and after a while , TV replaces real experiences. TV addicts stop talking to their families , don' t exercise , don' t see their friends , and don' t learn new things. Basically , TV addicts stop experiencing life.
E
The harmful effects of TV addiction may not be as obvious as those of cigarette ,drug ,or alcohol addiction ,but TV addiction can take a person' s life away. If you think that excessive TV watching is not harmful , keep track of how much TV you watch every day , and think about all the other things you could be doing during those wasted hours.
