Scientific research shows that in the process of meditation, people's heartbeat and heart rate decrease, breathing slows down, brain waves relax, muscles relax, the basic metabolic rate of the human body decreases obviously, oxygen consumption decreases, blood lactate decreases, stress hormones such as adrenaline decrease, white blood cells and red blood cells slow down, pressure is reduced, and immune function is obviously enhanced. Physiologists in the United States and Germany once selected people to carry out experiments in groups. After a period of time, the sit-ins take some time out for a walk every day, and then sit still and relax. Two or three months later, experts made a detailed inspection of them. These people's saliva immunoglobulin a.

Significantly increased. Meditation can reduce energy consumption more than sleeping. In reducing oxygen consumption, twenty minutes of meditation is worth six or seven hours of sleep. The energy consumption of ordinary people during sleep is about 16% lower than that during waking, and even 34% lower if they can sit still. We sit quietly every day, and it's easy to calm ourselves down. Because we are calm, our blood vessels are unobstructed, and we are not prone to diseases. On the contrary, if the mood is often troubled by anger, fear, sadness, depression and other emotions, it will easily lead to qi and blood imbalance, which will lead to many diseases over time. Therefore, from the perspective of Chinese medicine, long-term meditation can greatly replenish vitality and eliminate all diseases. The effect of meditation is more important in adjusting the heart. People's body and mind are inherently related. It has been reported that when people sit still, their brain waves are mostly alpha waves, and their oscillation frequency is between 8hz ~ 14hz. When brain waves are at this frequency, people's brains are awake, relaxed and focused, so they are easy to concentrate, not easy to be disturbed by other external things, and their brains are not easy to get tired. Their mental state is quiet, relaxed, happy and focused. When the brain waves are alpha waves, the human body is relaxed but conscious. Because in this state, the physical and mental energy consumption is the least, and the energy obtained by the brain is relatively high, the activities of the brain will be smooth, and people will become intuitive and easily inspired. Alpha wave is closely related to human spiritual comfort, in which "relaxation" and "concentration" are two conditions of alpha wave. Therefore, modern science actively advocates that alpha wave is the best brain wave state for people to learn and think. People are born with/kloc-0.4 billion brain cells, of which only about 25% are working, and 50% of people who sit still can move. Japanese research shows that when the brain is irradiated by alpha waves, the body will secrete more beta-endorphins, which have the functions of relieving pain, relieving mental stress, enhancing memory, improving immunity, preventing aging and being happy. Therefore, meditation is beneficial to human body and mind, not harmful.
