I hope my answer will help you. As we all know, the benefits of milk are abundant, and it is a good tonic for the old, the weak, the sick and the pregnant. However, many people think that drinking milk in winter is good in absorption and great in effect, while in summer, the climate is hot and people sweat a lot, so drinking milk is easy to get angry. Therefore, it is considered inappropriate to drink milk in summer. In fact, there is no scientific reason for this statement. Traditional Chinese medicine believes that milk is sweet in taste and slightly cold in nature, which is melted by the blood of cattle, and has the effects of moistening lung and stomach, promoting fluid production, relaxing bowels, tonifying deficiency and detoxifying.

Milk contains about 78% water, and protein and fat in milk are easily digested and absorbed by human body. Therefore, drinking milk in summer can not only replenish the water lost by the body, but also increase the nutrients, which is extremely beneficial to maintaining good health.

Of course, drinking milk in summer should pay special attention to hygiene to prevent milk from going bad. Because of its high nutrition and multi-components, milk can easily become a culture medium for bacteria to multiply in summer. Therefore, after the fresh milk is retrieved, it should be boiled and drunk, and it is best to cook and drink it now. The remaining milk should be stored in the refrigerator at a low temperature, preferably at 4℃, but it should not be frozen, otherwise the nutrients will be destroyed. In addition, don't add water to fresh milk that you can't drink for a while, otherwise it will go bad easily. In the final analysis, there are many benefits to drinking milk in summer, especially for the elderly. Children should also drink more milk drinks.
