Traditional Chinese medicine believes that nourishing yang in spring and summer can promote hair growth, while cold food has contractive effect, especially on the stomach and adjacent heart and arteries, leading to spasm. Therefore, eating cold food is not in line with seasonal health. Chinese medicine also believes that the best chance for the body to get rid of the cold all year round is the dog days, so you must not eat cold things at this time, otherwise it is easy to let more cold in and the original cold can not be discharged.

Frozen drinks and food satisfy the desire of the tongue, but not the stomach. Especially if you drink iced drinks or beer on an empty stomach, your stomach will be strongly stimulated. Drinking it may make you feel comfortable, but it will reduce the digestive ability of your stomach after a long time. Strictly speaking, cold drinks, popsicles, cold beer, etc. Spring, summer, autumn and winter are not suitable.
