Nowadays, with the development of modern society, the human health is greatly affected by the busy activities. People are always busy with their jobs. "24-hour society" has appeared all over the world. At the beginning, 24-hour society meant the rapid development of the modern society. Recently, 24-hour society has been used to mean the busy life of people in big cities.
People in big cities are always puzzled by many health problems caused by the busy life. Because of excessive activities and jobs, people can not get adequate rest in time. The functions of the brain have been hurt seriously. According to the medical research, the flow rate of blood in the brain can be increased when people are sleeping. Thus, the demand of brain cells to blood oxygen can be met and the discharge of wastes in the brain can be accelerated. In addition, adequate sleep can also enhance the memory and improve the intelligence for people. If people always stay up late, chronic dysfunction of brain can be caused. In addition, it is also easy for people to get cardiovascular diseases if people always stay up late. When people stay up late, the normal functions of the human organs and the normal standard of blood-fat can be disturbed. It can hurt the angiocarpy and cause coronary heart disease seriously. In addition, the high pressure of life and jobs can increase the blood pressure to cause high blood pressure and cerebral apoplexy. It has been proved that inadequate rest of the brain is an important reason to cause cardiovascular diseases. 24-hour society can also accelerate the aging of the human body and decrease the human immunity.
In order to keep healthy and avoid serious consequences caused by 24-hour society, it is important for people to form healthy habits in everyday life. For example, people should avoid staying up late and get adequate rest as far as possible. The night activities like staying in a bar should be reduced. It is also important for people to supplement essential nutrients like vitamin C, iron, zinc and calcium in time. In addition, people should take aerobic exercises in a right amount so as to improve the physical conditions. People can choose suitable kinds of sports like jogging and swimming according to their own physical conditions. Bad habits in everyday life can seriously endanger the human health. Therefore, bad habits like drinking coffee before going to bed should be thrown away.
