Scientific health ▏ health knowledge; immunity is not the stronger the better, these five points are the best way to improve the body’s disease resistance

No matter take any medicine, must avoid smoking. Nicotine in tobacco can accelerate the degradation of drugs in the liver, resulting in the decrease of drug concentration in the blood, making it difficult to give full play to the drug efficacy. < / P > < p > when standing, do not always use two legs to support the weight of the whole body. You can focus on it and let the two legs alternate to rest. Can stand on tiptoe, let heel drop together activity, or do leg kicking movement. The above actions can cause strong contraction of calf muscles and reduce venous blood accumulation. Immunity, like the “guard army” of human health, is responsible for cleaning up the aging, damaged and denatured cells in the human body, and undertakes an important defense task. < / P > < p > the immune system protects human health from many aspects. If the ability of immune system is low, people are easy to get sick. How about your immunity? It’s better to do a simple test ~ < / P > < p > 1. Physical fatigue: often feel tired, even if sleep time is more than 9 hours a day, still feel sleepy, can’t lift the spirit of work, and easily distracted. Frequent colds: colds more than 3 times in a year, especially in the alternation of seasons and sudden changes in temperature. The course of disease is usually 7 days or more, and bronchitis or pneumonia may be caused by cold. < / P > < p > first of all, low immunity can easily lead to bacterial and viral infection. If you always feel unwell, mentally poor, tired, or physically uncomfortable recently, it may be a sign that your immunity has declined slightly. It reminds you to pay attention to your own immunity. < / P > < p > secondly, too strong immunity is not a good thing. It is easy to have allergic reactions, such as rhinitis, allergic asthma, urticaria, etc. And the immune response is too strong, the immune system is likely to be indiscriminate, its own cell tissue as the “enemy” to attack and destroy, may easily suffer from lupus erythematosus, rheumatoid and other autoimmune diseases. Therefore, the best state of human immunity should be in the middle balance position, which is neither weak nor strong, so as to better protect our health. < p > < p > stress can increase the hormone components that inhibit the immune system of the human body, thus reducing the function of the immune system. Therefore, keeping an optimistic attitude is very important for health. < p > < p > sleep is closely related to human immunity. Famous immunologists through the “self sleep” test found that good sleep can significantly increase the number of two kinds of lymphocytes in the body. However, lymphocytes can produce and carry antibodies and defend against virus infection. Aerobic exercise such as walking, jogging, dancing and cycling can improve the cardiopulmonary function, blood circulation, lymphatic circulation and immunity. < p > < p > experiments have shown that exercise for 30 to 45 minutes a day, five days a week. After 12 weeks, the number of immune cells in human body will increase, and the resistance will also be relatively enhanced. Fungus and algae food, such as mushroom, fungus, tremella fuciformis and Porphyra, are not only rich in nutrition, but also can improve the immune function of human body. In addition to a variety of vitamins and minerals in mushrooms, there are mushroom polysaccharides, lentinan, etc., which are helpful to improve immunity. Sun exposure is the main way for the body to synthesize vitamin D. Modern people are more homestead, less time in the sun, the body’s vitamin D synthesis is less, will cause the human body immunity is low, easy to get sick. It is better to bask in the sun at 10:11 a.m. at this time, the air is better and the ultraviolet light is low, which makes people feel warm and soft. It can be dried for half an hour. < / P > < p > original title: < A= target=_ blank>You can play with mobile phones during pregnancy, but these four methods of “hurting your fetus” are not advisable.
