What harm does "not sitting on a stone in winter and not sitting on a tree in summer" do to people's health and how to adjust their diet?

As the saying goes, "Don't sit on a stone in winter and a tree in summer." After the slight summer heat, the temperature is high and the humidity is high. Wood placed in the open air for a long time, such as chairs and stools, is exposed to rain, contains more water, and the surface looks dry. But when it is exposed to the sun and the temperature rises, it will emit moisture. Sitting on it for a long time will induce hemorrhoids, rheumatism, arthritis and other diseases. Therefore, especially middle-aged and elderly people, we must be careful not to sit on the wood placed in the open air for a long time. Sleeping outdoors is also a bad habit for young people. Because, after people fall asleep, the sweat glands on their bodies still secrete sweat outward, and their bodies are in a relaxed state, and their resistance drops. After the temperature drops at night, the temperature difference gradually increases, which easily leads to headache, abdominal pain, joint discomfort, indigestion, diarrhea and so on.
