Precautions for drinking water:
1, it is best to drink warm water.
On the one hand, the intake of cold drinks will make the gastrointestinal mucosa suddenly catch cold, make the originally unblocked capillaries contract, and make the smooth muscles spasm, which may cause gastrointestinal discomfort or colic or even diarrhea. On the contrary, some people like drinking boiled water. Overheated diet will damage esophageal mucosa and stimulate mucosal hyperplasia, which has been the conclusion of medical circles. Therefore, the temperature of drinking water should not be too hot or too cold. The optimum temperature is 10-30℃.
Step 2 drink light but not sweet
Sweating in summer will not only lose water, but also lose minerals, vitamins and amino acids. So when it is hot, you should drink some light salt water to supplement sodium. Self-made mung bean soup and lemonade can not only cool down the summer heat, but also supplement vitamins and other nutrients.
It should be reminded that all kinds of sweet drinks are high in sugar content, high in energy and monotonous in nutrients. It is not recommended to drink in large quantities, nor can it be used to replace boiled water.
Drink slowly, but not too fast
When drinking water, many people are used to "binge drinking", but this way of drinking water is not good for their health. Drinking a lot of water quickly will dilute the blood quickly, increase the burden on the heart, and it is easy to swallow a lot of air together, which is easy to cause hiccups or bloating.
