Warm diet should be the main way to raise yang in spring and summer, and all cold things should be carefully eaten. Especially in the early summer, when the sun rises, the cold diet will directly damage the human yang and greatly weaken the cold resistance of the human body, so it will not be cold in winter. Moreover, a cold diet will hurt the stomach, weaken the function of digestion and absorption, make the nutrition fail to keep up, and lead to greater energy consumption in Xia Zhishi. Besides, don't be too greedy. If you stay in an air-conditioned room for a long time, or sleep in the wind all night, it is very harmful to your health.

In summer, it usually dawns at 6 o'clock in the morning, so people should get up at the right time, stand on piles or practice, breathe and exhale, which will help to improve the yang. The intensity of exercise can be increased appropriately. The so-called movement generates yang, and kinetic energy can better nourish yang and strengthen the function of viscera. However, the yang is not strong in early summer, so it is not suitable for strenuous exercise to prevent excessive injury and sweating.

"Winter disease" refers to some diseases that are easy to attack or worsen in winter, such as bronchitis, asthma and rheumatoid arthritis. In summer, we should use it to relieve the disease, treat it according to syndrome differentiation, and take some prescriptions orally and externally appropriately to prevent the recurrence of old diseases in winter or alleviate their symptoms.
