What is the relationship between exercise and immunity?

We all know that spring is a season when all things grow, which can help us dispel the cold and boost yang, so many of our friends will do some physical exercises. However, some experts say that excessive exercise in spring will lead to a decrease in our body’s immunity. This makes many friends puzzled, because general exercise can help us improve our immunity, so what is the relationship between exercise and immunity?

Expert: Nowadays, staying up late has become a lifestyle for some white-collar workers. From a health perspective, staying up late has many harmful effects. Staying up late can cause many kinds of damage to the body, such as fatigue and decreased immunity. Colds, gastrointestinal infections, allergen attacks, autonomic nervous system disorders, etc. will all "come knocking on your door."

11pm to 3am is the body's "beauty and leisure" time, which is the period when the body's meridians run to the gallbladder and liver. If these two organs do not get enough rest, they will show up on the skin, causing roughness, yellowish complexion, dark spots, acne, etc. For those who are not used to going to bed early, they should enter deep sleep at the latest at 1 a.m., the liver-nourishing time. It should be noted that staying up late for a long time will gradually cause people to develop neurological and mental symptoms such as insomnia, forgetfulness, irritability, anxiety, etc.

In addition, excessive exercise in spring can also reduce immunity. Foreign studies have shown that aerobic exercise three times a week is more appropriate. Too high intensity and intensive exercise will actually reduce immunity. The University of Toronto tested inactive people aged 19 to 29, asking them to do 40 minutes of aerobic exercise three or five times a week for 12 weeks. Blood tests found that the number of immune cells in those who exercised five times a week decreased by 33%, while there was no change in those who exercised three times a week. Experts believe that persistent aerobic exercise three times a week for 30 minutes each time can achieve health benefits.

The above is an introduction to the relationship between exercise and immunity. Many people prefer to do some fitness exercises when the spring comes. In fact, exercise is feasible and can help us exercise our bodies, but we must remember to do it within our ability when exercising, because excessive exercise will lead to a decrease in immunity.
