Tips for summer heatstroke prevention
1、 Replenish water in time but drink less.
Juice, cola, Sprite, soda and other drinks contain more saccharin and electrolytes. If you drink too much, it will cause adverse gastrointestinal stimulation and affect digestion and appetite. Therefore, we should drink more boiled water or light salt (sugar) boiled water in summer.
2、 Don't drink too much after you are thirsty.
After a lot of sweating in labor and sports, it is not suitable to drink a lot of white water, and some light salt (sugar) water should be added appropriately, because after a lot of sweating, the salt in the human body is lost too much, accounting for about 0.5% of the sweat. If the salt is not added in time, the proportion of water and salt in the body will be seriously out of balance, leading to metabolic disorder.
3、 The strongest time of solar short wave radiation is about 10:00-15:00.
Should try to avoid this period of time to go out, must go out, should be on the skin coated with some sunscreen skin care products, summer clothing to light color is good.
4、 Do not drink too much.
In summer, the human body is easily affected by the temperature to accumulate damp heat, and excessive damp heat is the cause of skin ulcers, carbuncle, swelling and toxin. If you drink a lot of white wine, it will help heat and damp, just like adding fuel to the fire.
5、 Diet should not be too light.
In summer, people have a long time of activity, sweat a lot and consume a lot. They should eat more nutritious food such as chicken, duck, lean meat, fish and eggs to meet the metabolic needs of human body.
6、 Nap time should not be too long.
If the nap time is too long, the central nervous system will be further inhibited, and the blood flow in the brain will be relatively reduced, which will slow down the metabolic process, resulting in discomfort and more sleepiness after waking up.
7、 Avoid 'fast cooling' after heating.
In summer, when people go out or come back from work, they like to either turn on the electric fan or take a cold bath immediately, which will make the pores of the whole body close quickly, and the heat in the body will be hard to emit, and the blood supply of the brain will be insufficient due to the rapid contraction of the blood vessels in the brain, making people dizzy.
8、 The indoor and outdoor temperature difference of air conditioner should not be too large.
The indoor and outdoor temperature difference of air conditioner should not be more than 5 degrees. Even if the weather is reheated, the indoor temperature of air conditioner should not be less than 24 degrees.
9、 Do not wear metal jewelry.
Some metals in metal ornaments are stained with sweat. When wearing, the skin may appear reddish or itchy, which is easy to cause contact dermatitis.
Six treasures of summer heat prevention
Salt boiling water:
Traditional Chinese medicine says "boiled water is the king of all medicines". From the point of view of nutrition, any beverage containing sugar is not as valuable as boiled water, because pure boiled water can be absorbed by the stomach quickly after entering the human body, enter the blood circulation to play the role of metabolism, regulate the body temperature and clean the internal environment of the human body.
To drink boiled water, we should choose the fresh boiled water (20 ℃ - 25 ℃) which is naturally cooled after boiling. This kind of boiled water has special biological activity, and it is easy to enter the cell through the cell membrane and be absorbed and utilized quickly. It's best to add some salt when drinking boiled water. In summer, with high temperature, excessive sweating and less salt in the body, the osmotic pressure in the body will lose stability, resulting in heatstroke. Drinking more salt boiled water or salt tea can supplement the salt lost in the body, so as to achieve the effect of heatstroke prevention.
Tea water:
Experienced health doctors often instruct people to supplement potassium by drinking tea. Potassium is an important trace element in human body. Potassium can maintain the normal function of nerves and muscles, especially the normal movement of myocardium. If lack of potassium, people will feel tired and lack of energy, and the ability of heat resistance is reduced. Severe potassium deficiency can lead to arrhythmia and general myasthenia. Tea contains more potassium, accounting for about 1.5% of its proportion. Potassium is easily excreted with sweat, and tea with appropriate temperature should be the first choice in summer.
Dan:
The main ingredients are mint ice, talc, catechu, clove, woody, fennel, Amomum, tangerine peel, etc. It has the effect of clearing away heat and relieving summer heat, avoiding pollution and stopping vomiting, and is a commonly used summer heatstroke medicine.

This medicine can promote peristalsis of intestinal tract and relieve spasm of intestine. Heat stroke, acute gastroenteritis, cough and phlegm are suitable for taking.
Mature vinegar:
In summer, people drink more water, and their stomach acid is correspondingly reduced, which makes their appetite decrease. Appropriate amount of vinegar can increase the concentration of gastric acid, promote the stomach and help digestion. If some vinegar is added in cooking, it can increase the concentration of gastric acid and increase appetite. Summer is the epidemic season of intestinal infectious diseases. Vinegar can also improve the bactericidal effect of gastrointestinal tract. In addition, if a few drops of vinegar are added during cooking, the loss of vitamin C in vegetables will be reduced, and the absorption of iron in food will be favorable.
Balsam pear:

The bitter taste of balsam pear can stimulate the secretion of human saliva and gastric juice, increase appetite, clear heat and prevent heatstroke. Therefore, it is appropriate to eat balsam pear in summer. Using fresh bitter gourd to pound the juice or decoct the soup, it is the best food therapy aid for the liver fire, the eyes red, the stomach hot and thirsty, the stomach ache and the damp heat dysentery.
