“Alas, I am so tired!”—— The fatigue brought by modern life to people is not only physical “fatigue”, but also psychological “fatigue”, and even physical “disease”.
fatigue is divided into several types.
First, physical fatigue.
It is often seen in manual workers, which is caused by heavy manual labor or excessive sports. The performance is weakness of hands and feet, and the whole body can be significantly reduced.
Second, mental fatigue.
It is mainly seen in mental workers. Because of the long-term complex mental work, a large amount of energy is consumed, resulting in insufficient blood and oxygen supply to the brain, which weakens the normal function of brain cells. It is manifested as dizziness, memory decline, insomnia and dreaminess.
Third, psychological fatigue.
It is caused by the high-intensity tension and pressure in modern life. Because of the overload of mental burden, the psychology is in a state of confusion and restlessness, and the mood is depression, depression or anxiety.
Fourth, chronic fatigue.
If you are a working person, toiling all day, and often working overtime, you will feel tired all over after you go home and go to sleep. When I wake up, it’s another day’s sprint. Then you may be confused by “chronic fatigue”. Many years ago, the first case similar to cold symptoms was found in the United States. Later, it was officially named “chronic fatigue syndrome”. From a medical point of view, it is a disease of severe fatigue caused by overwork or exercise.
