Matters needing attention in summer
1, although the temperature is high, we should still take care of the yang of the human body. Also known as "nourishing yang in spring and summer". Yang is the motive force of human beings, which fluctuates with the alternation of seasons and the sun and the moon. In summer, Yang is vigorous and often floats outside, but it is easy to be injured by external evils. If you sweat, you will die of Yang. In other words, in the hot summer, it is generally not appropriate to do a lot of exercise, and water and nutrients should be replenished in time after exercise.
2. After long summer, the northern hemisphere will get plenty of sunshine, the sunshine time will be prolonged, and the temperature will increase, so people's sleep will be reduced. People with sleep disorders are more likely to get worse, trouble sleeping, or restless at night. Chinese medicine says that it is appropriate to "lie down early and get up early" in summer to conform to the solar terms.
3. When entering the midsummer season, the temperature is high and the humidity is high, giving people a sultry feeling, which is what Chinese medicine calls long summer. Long summer belongs to the soil in the five elements, corresponding to the spleen of the five internal organs of traditional Chinese medicine, and the spleen hates dampness and likes dryness, so long summer often suffers from spleen and stomach diseases, and symptoms such as loss of appetite and diarrhea appear.
