Can cold drinks quench your thirst in summer 1

Drinking cold drinks is the best way to quench your thirst?

Most people always think that a cold drink can completely cool off the heat. But in fact, after drinking cold drinks, the surfaces of the mouth, esophagus and stomach will become cold rapidly, and then the microvascular walls of these parts will shrink due to the temperature drop, thus reducing the blood flow through them, thus reducing the ability to absorb water, and also making the water in human cells penetrate into the gaps, thus causing the phenomenon of "drinking too much and thirsty"!

Especially when a person quickly drinks a glass of ice water or eats a large glass of ice cream, the temperature in his stomach will drop rapidly from 37 degrees Celsius to below 20 degrees Celsius, so his stomach will "shrink" immediately, just like the car engine is broken, and he can't move any more! Therefore, if the stomach does not peristalsis, the digestive function of the gastrointestinal tract will stop. It takes about 30 minutes (or even longer) for the stomach to return to a warm state and the digestive function to gradually return to normal. Therefore, if you eat ice products at the same time, it will delay the transportation of food from the stomach to the small intestine, causing abdominal distension and indigestion.

Don't drink cold drinks for breakfast.

The human body always likes a warm environment. When the body is warm, the microcirculation will be normal, and the transportation of oxygen, nutrition and waste will be smooth.

So don't drink fruit and vegetable juice, iced coffee, iced juice, iced black tea, mung bean paste, iced milk, etc. At breakfast. You may not feel uncomfortable for a short time, but it will actually make your body weak. Why?

You should eat "hot food" for breakfast to protect your stomach. In fact, stomach qi in TCM theory is generalized, not simply referring to "stomach", but including the digestion and absorption ability of spleen and stomach, acquired immunity, muscle function and so on.

Because in the morning and at night, Yin Qi has not moved away, and the temperature of the earth has not risen. The muscles, nerves and blood vessels in the body are still contracting. If you eat cold food and drink cold food again at this time, all systems of the body will contract more and the blood flow will be worse.

Avoid eating too many cold drinks.

Eating too much will dilute gastric juice, affect digestion, stimulate the intestine, make peristalsis hyperactive, shorten the time of food staying in the small intestine, and affect the absorption of nutrients in food. In particular, people with acute and chronic gastrointestinal diseases should eat less or not. Avoid eating a lot of cold drinks after strenuous exercise, which will lead to an increase in body temperature and congestion in the throat. At this time, if the gastrointestinal tract and pharynx are suddenly stimulated by a large number of cold drinks, there will be abdominal pain, diarrhea or sore throat, hoarseness, cough and other diseases.

Avoid eating unsanitary cold drinks

Because Escherichia coli, Salmonella typhi and Staphylococcus pyogenes can survive at a low temperature of-170 degrees Celsius. Therefore, eating unclean cold drinks will harm your health, so you can't eat soda or popsicles without brands. Too many cold drinks will not only cause gastrointestinal digestive dysfunction, but also induce more serious diseases. Especially for the frail elderly, it is best to ban cold drinks.

Avoid eating stale cold drinks.

It is best to eat a cold drink with "clear color and fresh taste". We should carefully check whether the cold drinks are hygienic and fresh. Generally, juice drinks should not precipitate, bottled drinks should not leak, and they should be fragrant after opening. Fresh milk is milky white, the milk liquid is even, there is no precipitation, clots and impurities, and it has milky white smell. The surface of the iron drum for canned drinks should not rust, leak air or liquid, and the lid should not swell. If there is a drum sound when the canned drink is knocked, it means that the bacteria have multiplied and cannot be eaten.
