Huangdi Neijing ~ Diseases and Seasons

There are four seasons and five elements in the sky to grow and collect, resulting in hot and cold weather and dry and wet winds. People have five internal organs and five qi, which leads to emotions and fears. Therefore, anger hurts the spirit, and cold and heat hurt the shape; Anger hurts yin, and sudden joy hurts yang. Syncope ascending, pulse deformation. Irregular mood, excessive cold and heat, and unstable life. Therefore, heavy yin will be yang, and double ninth will be yin. So: winter cold is painful, and spring cold is hot; Spring is wind injury, summer is diarrhea; Summer hurts in summer and malaria in autumn; Dampness in autumn and cough in winter.

The changes of four seasons and five elements in nature have formed the law of growth and collection, resulting in a climate of hot, cold, dry and humid winds. People have five internal organs, which produce five qi and five emotions: anger, sadness and fear. Therefore, being too happy and angry will hurt the spirit, and the attack of cold and heat will hurt the body; Great anger will hurt Yin Qi, and great joy will hurt Yang Qi. If you go against the qi and the blood vessels are blocked, you will float over and leave your body. Therefore, if you don't control your emotions and adapt to cold and hot, your life will not be stable. Too grand will turn into yang, too strong will turn into yin. Therefore, if it feels too cold in winter, it is easy to have fever in spring; I feel too much atmosphere in spring, and it is easy to have diarrhea in summer; It feels too hot in summer, and it is easy to get malaria in autumn; I feel too much humidity in autumn and cough easily in winter. -Theory of Yin and Yang Images in Huangdi Neijing.
