Recently, I saw a piece of horrible news that a girl committed suicide, but none of her families had perceived the girls choice, because she was an active girl. Actually, many people have subhealth problems today, and most people havent realized this problem, thus the tragedy happens.The definition of a sick person is often believed to have illness in physical. But according to the health report, subhealth is the new type sickness that kills thousands of young people, because subhealth is not easy to be perceived and generally people dont consider that they have health issue. Subhealth is the potential illness. It may be the pressure you are suffering, or the bad emotions you are depressing. It is more of the mental illness.If subhealth is not treated in time, it will break out sooner or later. Some people will feel depressed and kill themselves, or some get sick badly after lacking of exercise for a long time. Taking regular exercises and keeping good mood are necessary ways to keep healthy. The proper adjustment can help us to stay away from subhealth.
