Some people believe that when the temperature is low in winter, the human body's metabolism slows down and the essence is sealed, making it suitable for tonic. Therefore, drinking milk is easy to absorb and has great efficacy; in summer, the climate is hot and the human body sweats a lot, so drinking milk can easily produce heat. Therefore, milk is ordered in winter and returned in summer.

In fact, this view has no scientific basis. According to traditional Chinese medicine, milk is sweet in taste and slightly cold in nature, and has the functions of nourishing the lungs and stomach, moisturizing the intestines, laxative, and tonifying deficiency. Li Shizhen, a great medical expert in the Ming Dynasty, recorded in "Compendium of Materia Medica": Milk can cure nausea and heat, replenish strain, moisturize the large intestine, treat dysentery, and remove jaundice. This shows that drinking milk does not produce heat. The human body sweats more in summer. Milk not only contains about 78% water, but its protein and fat are also easily digested and absorbed by the human body. It can be seen that drinking milk in summer not only replenishes the water lost due to sweating, but also increases nutrition and is beneficial to the body.
