How to prevent heatstroke in hot summer

I. Preventive measures

1, don't wait for thirst to drink water.

Don't wait for thirst to drink water, because thirst already shows that your body is short of water. Ideally, drink 1.5 to 2 liters of water every day according to the temperature. When sweating a lot, you can add some salt water appropriately to make up for the salt lost by sweating. In addition, the human body is prone to potassium deficiency in summer, which makes people feel tired and weak. Potassium tea is an excellent summer drink.

Seasonal vegetables in summer, such as lettuce, cucumber and tomato, have high water content. Fresh fruits, such as peaches, apricots, watermelons and melons, have a water content of 80-90% and can be used to replenish water. In addition, dairy products can not only replenish water, but also meet the nutritional needs of the body.

get enough sleep

In summer, the days are long and the nights are short, the temperature is high, the human body has a strong metabolism, consumes a lot, and is prone to fatigue. Adequate sleep can relax the brain and body system, which is not only beneficial to work and study, but also a measure to prevent heatstroke. The best time to sleep is from 22: 00 to 23: 00, and the best time to get up is from 5: 30 to 6: 30. Be careful not to lie under the air conditioning outlet and electric fan when sleeping, so as not to get air conditioning disease and catch a cold.

Travel to avoid the scorching sun

Remember to prepare sunscreen equipment when you go out in summer. 10- 16 It's best not to walk in the scorching sun, because the sun is strongest at this time, and the possibility of heatstroke is 10 times as usual! If you must go out at this time, you must take good protection, such as umbrella, sun hat and sunglasses, and if possible, it is best to apply sunscreen; Prepare plenty of water and drinks. In addition, in the hot summer, you can take heatstroke prevention and cooling drugs, such as ten drops of water, Ren Dan, essential oil, etc. It must be kept at hand in case of emergency. When going out, try to choose cotton, linen and silk fabrics, and wear less chemical fiber clothing to avoid heat dissipation in time when sweating a lot, resulting in heatstroke.

Second, several kinds of cool drinks

(1) Hot tea is a good drink in summer. What's good to drink in summer? Chinese medicine believes that only hot tea belongs to it.

Modern medical research shows that caffeine, theobromine, theophylline and aromatic substances dissolved in hot tea can excite the brain, which is beneficial to the regulation of body temperature center, and can strengthen the heart and diuresis, promote blood circulation, increase renal blood flow, accelerate metabolism, and make excess heat in the body excrete with urine. Drinking hot tea can promote blood flow to the body surface, open sweat pores, relax sweat glands, promote sweat discharge and emit heat. Some people have determined that drinking hot tea for 9 minutes can reduce the skin temperature 1℃-2℃, and the cooling can last for more than 15 minutes. Old people are thirsty because of lack of body fluids. Tea polyphenols, sugars, amino acids and various aromatic substances contained in tea can stimulate oral mucosa, promote saliva secretion, and play a role in promoting fluid production and quenching thirst. People suffering from obesity, hyperlipidemia, cardiovascular and cerebrovascular diseases and other chronic diseases are prone to heatstroke in hot summer. Tea polyphenols, vitamin C, ester polysaccharide and other components in tea have the functions of protecting cardiovascular health, reducing cholesterol and blood lipid, protecting hematopoietic function, increasing white blood cells and enhancing disease resistance. Therefore, drinking tea is very beneficial to keep fit and prevent heatstroke.

But drinking tea should be scientific, not excessive, and the tea should be light and moderate.

(2) Soymilk can relieve summer heat and reduce fire.

People sweat a lot in summer and consume a lot of energy, so most people will lose weight to varying degrees. On the one hand, it is important to relieve summer heat, on the other hand, it is also important to supplement nutrition. However, nutrients are lost too quickly in summer and are not easy to absorb; Moreover, tonic is easy to get angry, so summer tonic should be based on balanced nutrition, cooling down and removing fire, and it is not advisable to eat dry tonic. Do you know that a small cup of soybean milk can not only achieve the purpose of tonic, but also relieve summer heat?

Traditional Chinese medicine believes that soybean milk is flat and sweet, and has the effects of promoting fluid production and moistening dryness, "purging stomach fire to treat internal heat" and "benefiting underwater qi and controlling wind heat". As we all know, mung beans have the effect of relieving summer heat. The "two bean drinks for relieving summer heat" made of soybeans and mung beans has the effects of clearing away heat and relieving summer heat, moistening throat and quenching thirst. At the same time, it is rich in protein, vitamins, minerals and other nutrients. Regular drinking can balance human nutrition, regulate endocrine, reduce cholesterol, relieve arteriosclerosis, hypertension and protect liver.

Third, people who are prone to heatstroke.

1, the elderly are prone to heatstroke because of the atrophy of sweat glands on the skin and the decline of circulatory system function.

2, pregnant women because of pregnancy or postpartum physical exertion, weak body, if you stay in a room with poor ventilation and high temperature, it is easy to get heatstroke.

3. Infants and young children's systems are underdeveloped, with poor thermoregulation function and more subcutaneous fat, which is not conducive to heat dissipation.

4. Hot weather will excite the sympathetic nerves of patients with cardiovascular diseases and increase the cardiovascular load. Especially for people with heart failure, the heat in the body can not be distributed and accumulated in time, which is easy to suffer from heatstroke.

5. The body of diabetic patients is slow to respond to the temperature change of internal and external environment. Although heat has accumulated in the body, the patient's conscious symptoms appear late, which is easy to cause heatstroke.

6, some patients with infectious diseases, due to bacterial or viral infection can make the human body produce endogenous pyrogen, so that the body's heat production is accelerated. Inflammation can also cause the body to release some substances, causing vasospasm and contraction, which is not conducive to heat dissipation and is prone to heatstroke.

7. Malnourished people will lower their blood pressure due to lack of nutrition, which will lead to reflex vasoconstriction. They are also prone to recurrent diarrhea, leading to dehydration and electrolyte disorders and heatstroke.

8. People who take antihistamines, anticholinergic drugs, sleeping pills, etc. There will also be vasoconstriction, which will lead to disorder of thermoregulation center and easy heatstroke.

How to prevent heatstroke in hot weather? Heatstroke can be avoided if preventive work is done well.

In drinking water, we should first pay attention to replenishing water.

In summer, the human body volatilizes a lot of water, so you can't wait for thirst before drinking water. At this time, the body is already in a state of water shortage.

Sleep aspect

Hot weather also consumes a lot of physical strength and is easy to feel tired. Adequate sleep can relax the brain and body system and help prevent heatstroke. Be careful not to lie under the air conditioning outlet and electric fan when sleeping, so as not to get air conditioning disease and catch a cold.
