At present, many people take it for granted that they are healthy if their doctors don't diagnose a-
ny disease in them. Consequently, it is not necessary for them to worry about their health as long
as they have no illness. However, most people are not conscious that they are on the verge of poor
health, and that they are in the state of sub-health due to unbearable pressure from their work and
life.
In fact, the situation has become so serious that everyone should be aware of it and take immediate
actions. Usually the symptoms of sub-health are as follows. Above all, people tend to feel tired and
suffer from sleeplessness. What's more, people are more vulnerable to diseases and often lose their
temper easily. Thirdly, they are often overwhelmed by a strong sense of helplessness and void.
We should take urgent measures to improve the situation. On the one hand, it is important that peop-
le should resort to all kinds of leisure activities to relieve themselves of the great pressure. On
the other hand, they should remember that a balanced diet and regular living pattern are both benef-
icial for health. Last but not least, it is also necessary for people to take physical exercise on a
daily basis.
