Matters needing attention in rainwater health care

Don't cut your coat too early.

Pay special attention to the phenomenon of "late spring cold" during rainfall. After the rain, the moisture in the air increases, which makes the temperature not only low, but also humid in the cold. This wet and cold climate has certain influence on human internal organs and joints. "Dry and cold meat, wet and cold." Because of the surge of air in spring, hot people want to reduce their coats. The leakage of body heat and the exchange of wet and cold in the bones are easy to hurt the muscles and bones and cause diseases.

Old and infirm people should not use cold water.

According to China's theory of five elements, water corresponds to kidney, and kidney governs bone. In the rainy season, old and weak people wash their faces and hands with cold water. Dampness and cold easily invade joints, and yang is not enough to drive away cold. Wet and cold in their hands means that they are prone to soreness and deformation. Wet and cold stay in the head, and the head is prone to pain.

Don't wash your hair or blow dry it.

After washing your hair, dry it with a hot air blower in time. Otherwise, the wet water stays in the hairline and cools down, and the "seeking common ground" makes the wet cold gather in the head and penetrate into the skull from the outside to the inside, leading to headache. If the hair is not dry and is blown by the cold wind, it is easy to have the symptoms of "partial wind".

Don't eat hot and dry food.

"Spring cold" is easy to block the internal organs, and it is not easy to eat hot and dry food to "add fuel to the fire". Heat depression makes people "greedy for cold", and if they eat too much cold, they will "seek common ground", which will hurt the viscera and cause imbalance symptoms such as stomach cold, stomach cold and diarrhea. Therefore, the diet should be moderate, hot meals and hot dishes should be eaten, but it is appropriate to eat warm foods such as peppers carefully and drink less white wine.
