Why is it said that "you don't sit on wood in winter and you don't sit on rocks in summer"?
The correct statement on this issue should be "Don't sit on rocks in winter, and don't sit on trees in summer." We get tired when we are walking outside, and we often find a place to sit down and rest. But in winter, when the weather is particularly cold, it is not suitable to sit directly outside on stone benches or steps. No matter how thickly you wear your clothes, you cannot sit on a rock in winter.
Because stone has strong thermal conductivity. In winter, because of the lower temperatures, the stones will be particularly cold. When we sit on stone benches or steps, cold air will invade the body. If you develop this habit of doing it anywhere, it will seriously imbalance the body's metabolism. It will cause damage to the liver and kidneys. Because the intrusion of cold air will cause damage to the body's yang energy.
In the summer, because the weather is not stable enough, the sky is not sunny every day, and there are often cloudy and rainy days. Especially in southern cities. Because frequent rains will cause outdoor wooden chairs to absorb a lot of moisture and moisture. Although the weather cleared, we saw that the road outside had become very dry. In fact, the wooden chair is emitting moisture. When we are tired from walking outdoors, sitting on wooden chairs and stools for a long time can easily lead to moisture intrusion. It can even induce skin diseases and arthritis.
Many patients suffer from hemorrhoids because of bad living habits. Find a random place outside and sit down to rest, often for a long time. Therefore, when we usually choose a resting environment outside, we must pay attention to the material of the seat. Sit less often on wooden chairs and stone benches in the open air.
