In summer, because of the hot weather, cold drinks and other cold foods are very popular. In hot summer, if the gastrointestinal tract is stimulated by a large number of cold foods, it will accelerate peristalsis, shorten the residence time of food in the small intestine, and affect the absorption of food nutrition by the human body. At the same time, due to the high temperature in summer, the heat in the body is not easy to dissipate, and the temperature of the gastrointestinal tract is also high. If you are suddenly stimulated by cold, it will lead to gastrointestinal spasm and abdominal pain.

Don't turn on the air conditioner too much.

We also need to pay attention to the essential air conditioning in summer. It's best not to turn it too big, because it can bring people a comfortable environment. However, if the temperature difference between indoor and outdoor is too large, it is difficult for people to adapt to the indoor and outdoor temperature changes and it is easy to "catch a cold". Moreover, if the temperature difference between indoor and outdoor is too large and indoor ventilation is not paid attention to, the indoor air will be turbid, leading to the breeding of various pathogenic microorganisms. If a person's body resistance is reduced, it is easy to get sick.
