Summer is the peak of growth. Because the sunshine is long and the sun is full, everything grows on the sun, and man is the spirit of everything. Everything in the world grows according to the laws of nature in summer to meet the cold winter. If human beings don't know how to use this time to grow up and be healthy, it will really fail the gift of nature. Traditional Chinese medicine has the theory of "treating winter diseases in summer". Diseases that are prone to attack in winter, such as asthma, respiratory allergy, itchy skin, chilblain, etc., can strengthen the body and promote yang through conditioning in summer, and can resist the invasion of evil spirits in winter. If you don't keep healthy in time in the most prosperous season, you will miss the cat.
