With the contemporary people's attention to physical health, more and more health preservation methods appear in people's field of vision. It is normal to soak Lycium barbarum in a thermos cup.

There are many seemingly incredible health preserving methods, which are favored by middle-aged and elderly people.

When you go for a walk in the park, you will always notice some old people. Their backs are against a big tree, their hips exert their strength, and they hit the tree with their backs to achieve the effect of fitness.

According to the old man, hitting a tree can dredge the tendons, promote blood circulation and remove blood stasis, and even achieve the effect of massage. However, as a young man, I personally tried it and found it really painful. I don't know how the old man's heart thumped. More importantly, there is no scientific basis for this method of hitting trees. Because it hits the back where the human spine is located, it is very dangerous to hurt yourself if you accidentally use too much force, ranging from scratch to fracture, and may even oppress the internal organs, resulting in damage to the internal organs.

Whether in summer or winter, we can always see one or several old people on a big stone. They especially like to sit on it and chat, because the smooth surface of the stone is not much more comfortable than sitting on a bench.

In summer, the warm touch of stones makes them feel that they can dispel dampness and detoxify and even promote blood circulation. However, the fact is that overheating of stones can lead to water loss and even burn the skin. In winter, although the stone is cold, it can't sit easily. Because there is a saying among the people? No stones in winter, no trees in summer? It means that the weather is very cold in winter, and the stone will absorb the cold air from outside. If people sit on a stone for a long time, it is easy for cold to enter the body, leading to metabolic disorder and affecting the kidneys.

Now that the internet is so developed, you must remember that Dochado has consulted professionals and don't follow suit when you see some wonderful health care methods. In pursuit of uniqueness, he backfired and hurt his health. We should keep healthy, but we must keep healthy.
