First, drinking water is not thirsty. Water is an important substance to maintain the normal operation of human life activities and prevent diseases and keep fit. Insufficient water intake not only leads to listlessness, dry mouth and general weakness, but also leads to the decline of liver and kidney function, which makes toxic substances accumulate in the body and makes diseases take advantage of it. People feel thirsty, which means there is no water in their bodies. The new concept of health preservation holds that it is beneficial to health to replenish water in small quantities and drink warm water, light tea, juice or milk before feeling thirsty.

Second, smile more when there is no happy event. Modern people live and work nervously and have fierce competition. Usually, few happy events can make people laugh. But as long as you keep an optimistic attitude towards life and face life with a smile, you can keep fit.

Keep your body and mind happy, and smile more when you are free. Middle-aged people are now under more pressure, whether they are children or young people. How long has it been since you laughed? Are you out of breath because of a lot of trouble? Relaxation and smiling are good for your health.

Third, don't be tired and have a rest. After working and studying for a period of time, although there is no sense of fatigue, if you can take a break, you will accumulate metabolic wastes (such as lactic acid and carbon dioxide). ) will be excreted in time, which is beneficial to anti-fatigue and health. You don't have to lie down and rest. You can close your eyes and sit still for a while, or stretch your arms, bend over, or have fun.

Many people around me work during the day and work part-time at night. She works 14 or 15 hours a day, and works 8 hours a day. You don't feel tired, but you think you can persist. In fact, you are wasting your body's ability. Work is important, but health is more important. It is good for your health to have a rest when you have nothing to do.

Fourth, painless physical examination. It is not a "patient's business" to go to the hospital regularly for a comprehensive physical examination every year. Regular physical examination is an effective measure for middle-aged and elderly people to find diseases early and prevent them in time.
