In summer, many people like to drink iced drinks and eat iced watermelons, which is very bad for their health. Why?

1. Gastrointestinal injury. Drinking cold beer in hot summer can quench thirst, relieve summer heat and make people feel more happy. For ordinary people, it's okay to drink a little cold beer, but drinking too much is harmful to your health. Because cold beer is cold after all, people's bodies were in a very hot state at that time, and suddenly pouring cold beer into the intestines and stomach can easily cause harm to the intestines and stomach, because the intestines and stomach can't stand such stimulation. After a long time, it is easy to cause gastrointestinal diseases and is likely to affect gastrointestinal digestion.

2. It is easy to cause diarrhea. I drank a lot of cold beer last night, and many friends had diarrhea easily the next day, and some people felt very painful. In fact, this is the disadvantage of drinking too much cold beer. People used to say that you can't eat things that are too cold, or you will have diarrhea easily, but cold beer is not only cold, but also very cold. Drinking too much ice water in your stomach is easy to hurt your stomach, leading to stomach problems and eventually abdominal pain and diarrhea.

Easy to catch a cold. Drinking too many cold things can easily reduce your body's resistance and make you catch a cold. Cold beer itself is a particularly refreshing thing, and it can also reduce the body's resistance.

In short, it is not good to eat frozen food often. For example, people put something with a temperature equal to or lower than 0℃ into their stomachs, but the urine discharged is hot, and the temperature of urine is about 37℃. So who turned cold things into urine at 37℃? The answer is spleen and stomach. When the spleen and stomach can't stand drinking, you must take out the essence (vitality) in the human kidney and convert it into heat energy, and cook these cold things to 37℃, so the old tune will weaken your kidney.
