For several days in a row, many people in the capital have been "knocked down" by the high temperature: don't blindly pursue "cool" to be "comfortable" in summer, and don't drink too cold to avoid damaging the gastrointestinal tract.

What are the dangers of summer greed

1. Easily lead to gastrointestinal disorders.

Frozen food and drinks are people's favorite in summer. However, although these things are cool and delicious to eat, they will affect appetite and adverse digestion. They will also cause local vasoconstriction due to excessive stimulation of gastrointestinal mucosa, resulting in gastrointestinal ischemia, hypoxia and gastrointestinal dysfunction. Moreover, if the person has chronic gastritis or gastric and duodenal ulcer, it is likely to cause acute attack, especially after eating air-containing cold drinks, it may lead to massive bleeding of gastric and duodenal perforation and endanger life.

2. It's easy to catch a cold.

In hot summer, many cities may be unstable if they don't have air conditioning. Even if they don't have air conditioning, people will blow the electric fan in hot summer before they can sleep. However, avoid excessive greed. Many people rely on the electric fan to cool all night. And blowing directly against the body. As a result, the electric fan blows the skin cold for a long time, resulting in a large loss of water in the body. When you wake up the next day, you will feel dizzy, depressed and loss of appetite. Sometimes, epistaxis or cold may occur due to too dry nasal cavity. If conditions permit, the air conditioner should be installed. Even if the electric fan is used, pay attention to avoid blowing directly against it, which is very easy to cause problems.

3. Induce female dysmenorrhea.

Cold drinks stimulate uterine contraction and increase pain. Therefore, if a female friend with dysmenorrhea must avoid drinking cold drinks or eating cold food during menstruation.

Staying up late in the cold does great harm

Some people have heatstroke symptoms such as dizziness and nausea due to staying up late to watch the ball and the heat of the day; On the bus and subway, many young passengers fainted due to heatstroke and hypoglycemia;

In the maternity ward of Beijing Shijitan Hospital, four pregnant women came in a day. One of them had a fever due to blowing the air conditioner all night, one had abdominal pain and diarrhea due to eating too many "cold drinks", and two felt that it was too hot and had too little activity, leading to thrombotic diseases.

The air-conditioned environment is relatively closed. Living in an environment with poor air circulation for a long time, the body's resistance decreases, and it is easy to be infected by bacteria or viruses. Pregnant women are likely to become the first infected because of the decline of immunity,

So don't blindly pursue "cool" and "comfortable" in summer, and don't drink too cold, so as not to damage the gastrointestinal tract.

In addition, when the weather is hot, the blood vessels of the human body dilate and the blood flow is slow, especially in the hypercoagulable state of pregnant women's blood and "too static", it is easy to have lower extremity venous thrombosis. Once the embolus falls off seriously, pulmonary embolism can occur, even life-threatening.

Therefore, pregnant women can't "be lazy" in hot weather. They can take a walk for at least 3 hours a day. If possible, they can swim, yoga, and even properly do some light upper limb strength exercises.
