If a person stays in the same position for a long time, his or her hands and feet become "numb". This is because "inactivity = no stretching of the muscles", so the lymphatic circulation can't work properly. Therefore, proper exercise is very important for lymphatic circulation. So is exercise good for your health? Research has shown that different exercise loads have different effects on immune function. Moderate exercise loads improve immune function and reduce the risk of infectious diseases, while heavy exercise training has a suppressive effect on immune function.
Through the study of exercise immunology, we have found that moderate exercise increases neutrophilic leukocytes, macrophages, and NK cells. The activity of NK cells, which process cancerous cells, increases depending on the intensity of exercise and decreases after stopping exercise. However, the activity of NK cells decreases after intense exercise or exercise lasting more than 2 hours. When they stop exercising, their function goes down all at once.
Also, although intense exercise elevates the gluttony of macrophages, antigen-presenting capacity and the acquired immune function of T cells are reduced. Studies have concluded that every moderate-load exercise provides a boost to the body's immune surveillance function and appears to reduce the body's risk of infection over a longer period of time. What is moderate-load exercise? Strictly speaking, everyone's physical, lifestyle, and mental energies are different, so you can't generalize.
Basically speaking, as long as one breathes smoothly during exercise and allows the body to reach the point of sweating slightly, another indicator is that the heart rate index is controlled at about 90-120 beats per minute. Fitness qigong has inherited the idea of moderation of exercise from ancient health care practitioners, and selected fitness qigong that has been experimentally proved to belong to low-intensity and moderate-intensity exercise. Low-intensity and moderate-intensity exercises are conducive to improving human immunity. Therefore, it can be said that fitness qigong exercise is conducive to improving human immunity.2 The relationship between relaxation and tranquility and immunityThe internationally renowned immunologist, Prof. Toru Atsushi of Japan, has discovered that autonomic nerve (also known as phytoneurotic nerve) disorders can affect the balance of lymphocytes and granulocytes in the leukocytes and lower the immunity of the human body, thus leading to the occurrence of diseases, which he called "the law of autonomic innervation of the leukocytes". of autoregulation".
The autonomic nerves are sympathetic and parasympathetic, and each is not static. Rather, when one side is dominant, the other's function is reduced, in a mutually antagonistic relationship. The more intense this fluctuation, the worse a person's health will be. If the state of favoring one side or the other persists for a long period of time, a person's body temperature will drop and his immunity will be lowered, which will lead to the development of diseases. The sympathetic nerve is the nerve that acts during the day, when we are engaged in activity or in a state of arousal. It speeds up the beating of the heart and breathing, delivers oxygen to the body, raises blood pressure, increases blood flow and constricts blood vessels.
Excessive stress due to things like hard work, worry and worrying can cause the sympathetic nerves to dominate, at which point the adrenal glands secrete a large amount of a hormone called adrenaline, which constricts the blood vessels so that there is an obstruction to blood flow throughout the body, cells do not get the necessary oxygen and nutrients etc. The parasympathetic nerves are the ones that act at night, while sleeping, eating, and laughing.
It relaxes the nerves, slows down the activity of the heart, dilates the blood vessels, and blood flows in large quantities. Fitness qigong emphasizes relaxation and stillness, and the movements are simple and easy to learn, so the practitioner can quickly enter a state of relaxation and stillness, and by maintaining this state of relaxation and stillness, the parasympathetic nerves are prioritized, thus relieving stress and causing the body's immunity to rise.
