Summer health, clearing away dryness and reducing fever are the key to summer health, and nourishing the heart is the most important. Summer is the season with the most abundant yang, and the climate is hot, which is a period of metabolism. When yang is emitted and yin is hidden, blood circulation is correspondingly vigorous and active on the body surface. Pay attention to nourishing the heart. Summer is the high incidence of heart disease. Chinese medicine believes that "the heart is connected with summer qi", and the yang of the heart is the most vigorous in summer, so more attention should be paid to the health care of the heart in summer. Summer health care focuses on mental adjustment, maintaining a happy and stable mood, and avoiding great sadness and joy, so as not to add fuel to the fire. Calm people and cool themselves, which can achieve the purpose of health preservation.
