Many people have already known quite well about the concept of sub-health. Have you heard about “sub-happiness”? In fact, most of us have experienced sub-happiness in our daily life. 

Maybe in others' eyes, you are a rather happy person with a respectable job, a lovely family and a breezy personality. You always smile to your colleagues, to your boss and to your clients. Many other people may have expressed their envy and admiration to you. However, you are probably not happy at all. You have to pretend to be happy. In fact, such a kind of seemingly happy mood is sub-happiness. Many reasons can result in sub-happiness.

The first reason which has been puzzling many people is the difficulty of dealing with the complex interpersonal relation. Many people in workplaces have experienced that some colleagues praise you before you but slander you behind your back. Nowadays, the competition is becoming more and more severe, and personal interests cause people to be catty in workplaces. It is rather difficult for people to solve the complex problems of interpersonal relation. The feeling of losing control of life is the second reason which causes people to become sub-happy. In order to maintain a nice job and get a chance of promotion, many people have to stay up late at night. They must reduce the sleeping time and disarrange their everyday diet. One day, people suddenly find that they are unable to control their own life. What they can do is just to be controlled by the reality. Marriage problem, family problem and even the education problem of the kids are also puzzling many people. Too much energy is invested in the work, which forces people to leave the family out of consideration.

In order to maintain mental health, it is important to for people improve this kind of sub-happiness. People can look for some hobbies for themselves. When they do what they really like to do, the sorrows of work can be transferred. At the same time, it is also important to make several good friends. Good friends can bring the sense of security to us and can also provide some information and help for us when we are in need. To let the sorrows out in time is beneficial to the mental health. People can let the sorrows out by talking with good friends or taking some aerobic exercises. With enough oxygen inside the body, people can keep the heart safe and sound.
