Immunity can also be called "righteousness". As the saying goes, "healthy qi exists inside, and evil cannot be done." The so-called "healthy qi" refers to the resistance to pathogenic microorganisms and their own adaptive ability, and "evil" refers to various pathogenic factors. Therefore, with the arrival of the immune epidemic, we should actively "strengthen the body's resistance" and improve the body's immunity.
Immunity is also a "good medicine" for preventing and treating diseases. It is like an army stationed in the body, shouldering the heavy responsibility of defense. When the human body is attacked by "enemies" such as bacteria and viruses, the immune system will immediately "fight".
When immunity declines, the human body is more vulnerable to viruses, bacteria and so on. And there will be more colds, slower wound healing, endocrine disorders, insomnia and other symptoms. Human immunity is not composed of one factor, but consists of five aspects: physical barrier of respiratory tract, complement system in blood, lung epithelial cells, natural immune defense system and acquired immune system.
Staying up late is a common problem of many people, which makes people form the habit of staying up late at work and staying up late on rest days. It seems that staying up late will not bring danger to health, but staying up late, like smoking, requires people to accumulate bit by bit.
Middle-aged and elderly people should learn to consciously control their diet, reduce the intake of salt, sugar and oil, eat less greasy food and change bad eating habits. At the same time, they should also maintain the intake of nutrients and timely supplement high-quality protein, vitamins and minerals. The following kinds of meat are good choices for the elderly.
The sleep quality of many elderly people will decline, and those who sleep deeply will spend less and less time. Sleep is very important to our health. When people go to sleep, they will produce sleep factors, which can increase the number of white blood cells, thus enhancing the detoxification function of the liver and eliminating bacteria entering the human body. The elderly have good sleep quality, which is a healthy and effective way to improve immunity.
Sleep can not only eliminate fatigue and make people energetic, but also improve immune function and disease resistance. Generally speaking, normal adults should ensure 7~9 hours of sleep, and the elderly should not be less than 6 hours. But the specific situation varies from person to person, and it is advisable to wake up energetic the next day.
