The following is a selection of summer heatstroke prevention and cooling knowledge (10). Welcome to read!

Knowledge of heatstroke prevention and cooling in summer 1

1. Self heatstroke

In the scorching sun, if you feel dizziness, nausea, palpitation and other corresponding symptoms, it is probably heatstroke. At this point, you should immediately stop what you are doing and find a cool place to sit down and rest; At the same time, it is necessary to replenish water in time, but don't drink it in big gulps, and drink it slowly in small sips so as not to increase the burden on the heart; Untie neckline, tie, belt and other accessories to keep the body ventilated; Apply or drink summer medicine; After a period of rest, if the symptoms do not decrease but increase, you should seek help and medical treatment in time.

2. Others have heatstroke.

Once someone around you has symptoms of heatstroke, you should immediately move the patient to the shade and keep the surrounding ventilation; Untie your clothes and help your body dissipate heat in various ways; Help to eat summer medicine; Pressing acupoints such as Renzhong and Hukou can help to restore consciousness. If the symptoms are not relieved, you should call the police for help immediately.

Dietary taboos after heatstroke

The weather is hot in summer, especially after entering the midsummer, the humidity increases obviously, the air circulation is poor, and it is even more sultry. People who often work outdoors or have low resistance are prone to heatstroke. In addition to timely treatment after heatstroke, there are four major taboos to pay attention to in diet.

1. Avoid drinking plenty of water.

People suffering from heatstroke should drink a small amount of water many times, and it is advisable to drink no more than 300 ml each time. Never drink too much. Because drinking plenty of water will not only dilute gastric juice, affect digestive function, but also cause hyperreflexia and sweating. In this way, a lot of water and salt in the body will be lost, which can promote thermal spasm in severe cases.

2. Avoid eating a lot of cold fruits and vegetables.

Most people suffering from heatstroke belong to spleen and stomach weakness. If you eat a lot of cold fruits and cold food, it will damage the yang of the spleen and stomach, make the spleen and stomach weak, and the cold and dampness will stagnate. In severe cases, there will be symptoms such as diarrhea and abdominal pain.

3. Avoid eating too much greasy food

Eat less greasy food after heatstroke to adapt to the digestive function of gastrointestinal tract in summer. If you eat a lot of greasy food, it will increase the burden on the gastrointestinal tract, so that a large amount of blood will stay in the gastrointestinal tract, and the blood delivered to the brain will be relatively reduced, and the human body will feel tired and more likely to cause indigestion.

4. Avoid simple tonic

After heatstroke, the heat is still there. Although they have shortcomings, they can't simply take supplements. It is a big mistake to think that you are weak and in urgent need of tonic. Because if you take supplements too early, it will make the summer heat difficult to subside, or the summer heat that has gradually subsided will come back, and it will not be worth the candle.

1. Replenish water in time, but drink less drinks. Juice, cola, sprite, soda and other drinks contain more saccharin and electrolyte. Drinking too much will cause bad stimulation to the gastrointestinal tract and affect digestion and appetite. So drink more boiled water or light salt (sugar) boiled water in summer.

2. It is not advisable to binge drink after being thirsty. It is not advisable to drink a lot of white water after sweating a lot during labor and exercise. Add some light salt (sugar) water appropriately, because too much salt is lost in the body after sweating a lot. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder.

3. The strongest time of solar short-wave radiation is around 10- 15. Try to avoid going out during this time, and apply some sunscreen skin care products to your skin. It is best to wear light clothes in summer.

4. It is not advisable to drink too much alcohol. In summer, the human body is prone to accumulate damp heat due to the influence of temperature. Excessive damp heat is the cause of skin sores and swelling. Drinking too much helps to clear away heat and promote diuresis, which is tantamount to adding fuel to the fire. After waking up, I feel uncomfortable and more sleepy.

5. The diet should not be too light. In summer, people spend a lot of time sweating and consume a lot. They should eat nutritious food, such as chicken, duck, lean meat and fish, to meet the metabolic needs of the human body.

6, the nap time should not be too long, the nap time is too long, the central nervous system will deepen the inhibition, the cerebral blood flow will be relatively reduced, and the metabolic process will slow down, leading to discomfort after waking up and more sleepiness.

7. Avoid "rapid cooling" after heating. In hot 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, but the heat in the body is difficult to dissipate, and it will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which makes people dizzy.

8. The temperature difference between indoor and outdoor air conditioners should not be too large. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees.

9, unfavorable wear metal jewelry. Some metals in metal ornaments are stained with sweat, and the skin will be red or itchy when worn, which may easily lead to contact dermatitis.

There are many ways to prevent heatstroke and cool down. The following are some commonly used heatstroke prevention and cooling items.

tea boiled water

Potassium is an important trace element in human body, which can maintain the normal function of nerves and muscles, especially the normal movement of myocardium. Scientific analysis shows that tea contains more potassium, accounting for about 1.5% of its proportion. Potassium is easily excreted with sweat, so tea with suitable temperature should be the first choice in summer.

bitter gourd

Bitter gourd is fragrant and delicious because of its bitter taste, and it is regarded as a rare dietotherapy product. China folks have had the experience of "bitter can clear away heat" and "bitter can strengthen the stomach" since ancient times. Chinese medicine believes that bitter gourd tastes bitter and cold, and can clear away heat and purge fire. Bitter taste of bitter gourd can stimulate the secretion of saliva and gastric juice, increase appetite, clear away heat and prevent heatstroke, so it is appropriate to eat bitter gourd in summer.

mature vinegar

When people drink more water in summer, their stomach acid decreases correspondingly and their appetite decreases. Proper amount of vinegar can increase the concentration of gastric acid, stimulate appetite and help digestion. Adding vinegar when cooking can increase stomach acid and increase appetite. Summer is the epidemic season of intestinal infectious diseases, and jealousy can also improve the bactericidal effect of gastrointestinal tract. In addition, if you add a few drops of vinegar during cooking, it will also reduce the loss of vitamin C in vegetables and help people absorb iron in food.

Salty water

Traditional Chinese medicine calls boiled water "the king of all medicines". Drinking boiled water should choose fresh cold boiled water (20℃ to 25℃) that is naturally cooled after boiling. This kind of boiled water has specific biological activity, and it is easy to enter cells through the cell membrane and be quickly absorbed and utilized. You'd better add some salt when drinking boiled water. In summer, the temperature is high, sweating is much, the salt in the body is reduced, and the osmotic pressure in the body will lose stability, leading to heatstroke. Drinking salty boiled water or salty tea can supplement the salt lost in the body, thus achieving the effect of heatstroke prevention and cooling.

People's diet in midsummer is very important, because people work in a hot environment, and obvious changes have taken place in body temperature regulation, water and salt metabolism, circulation, digestion, nervous system, endocrine system and urinary system, which will lead to an increase in nutrient consumption and a large amount of water and nutrients will be lost due to sweating.

People's loss of appetite in summer will also limit the absorption of nutrients. Expert advice: pay attention to supplement some nutrition. To supplement enough protein, fish, meat, eggs, milk and beans are better.

Vitamin additive

Fresh vegetables and fruits, such as tomatoes, watermelons, bayberry, melons, peaches and plums. Rich in vitamin c; Vitamin B is abundant in cereals, beans, animal livers, lean meat and eggs.

Supplementing water and inorganic salts

Edible foods with high potassium content, such as fruits, vegetables, beans or bean products, kelp, eggs, etc. Eat more foods that clear away heat and promote diuresis: watermelon, bitter gourd, peach, dark plum, strawberry, tomato, cucumber, mung bean and so on.

In addition, drinking porridge in summer is also of great benefit. Red bean porridge has the function of tonifying kidney and eliminating edema, and people with poor renal function had better eat more. Broad bean porridge is good for chronic edema and nephritis. Lotus leaf porridge can relieve summer heat, clear stomach and moisten intestines, quench thirst and detoxify. Lotus porridge can strengthen the spleen and replenish qi, and is good for diarrhea, insomnia, nocturnal emission and leucorrhea.

Lily porridge can moisten the lungs and relieve cough, nourish the heart and soothe the nerves, and is suitable for the elderly with insufficient lung yin. Winter melon porridge has the effects of diuresis, detumescence, quenching thirst, promoting fluid production and lowering blood pressure. Auricularia auricula porridge can promote fluid production and moisten lung, nourish yin and moisten lung, and can treat hypertension and chronic bronchitis. Astragalus porridge can treat edema caused by spleen deficiency.

In hot summer, the temperature remains high, and many people are reluctant to go out under air conditioning. Nevertheless, there are still many people who suffer from heatstroke unfortunately, so how to prevent heatstroke and cool down in this hot summer? What are the methods of heatstroke prevention and cooling? Let me introduce you.

Causes of heatstroke

Working in high temperature (generally room temperature exceeds 35℃) or working in the hot summer sun for a certain period of time, and there are not enough heatstroke prevention and cooling measures, it is often prone to heatstroke. Sometimes, although the temperature can't reach high temperature, heatstroke can also occur due to high humidity and poor ventilation. Common inducing factors are:

1. Environmental factors

It is an essential factor, including high temperature, high humidity and poor ventilation, which leads to increased heat gain and heat dissipation obstacles.

2. Thermal adaptation disorder

Chronic diseases, obesity, malnutrition, old age and infirmity, pregnant women, excessive clothing, excessive fatigue, lack of physical exercise, lack of sleep, drinking and dehydration will all interfere with the body's thermal adaptation.

3. The body produces more heat.

Engage in heavy manual labor. Hypermetabolism such as infection, fever, hyperthyroidism, etc.

4. Body heat dissipation disorder

Mainly seen in sweat gland dysfunction, such as congenital sweat gland deficiency, sweat gland injury, large area skin injury (large area burn, scleroderma, etc.). ), allergic diseases and anticholinergic drugs such as atropine; In the environment with high humidity and poor ventilation, it is also prone to heat dissipation obstacles; The slow response of cardiovascular regulation in patients with cardiovascular diseases can affect the heat dissipation mechanism.

1, use heatstroke prevention and cooling tools.

Using air conditioners, fans, sleeping mats, sun hats and water are good tools for heatstroke prevention and cooling, so it is necessary to ensure that these sunscreen products can be used normally when summer comes.

2. Replenish water in time

Drink more warm water in summer, or light salt water, honey water and tea are all good choices. But drink less drinks, especially cola, sprite and soda, which contain a lot of saccharin and electrolyte, and are not suitable for drinking more. Drinking more can not only relieve summer heat, but also affect appetite.

Step 3 wear the right clothes

You sweat a lot in summer, so you should pay attention to choosing clothes with good sweat absorption effect, and never choose chemical fiber clothes, because chemical fiber clothes absorb sweat the worst. At the same time, don't choose dark clothes, because black clothes easily absorb the wavelength of the sun and make you hotter. On the contrary, some light-colored clothes are a good choice. Some studies say that wearing red clothes in summer is the best protection against heat, so you can try more. Summer clothes should be thin, but not too short, because the skin has no self-cooling function, so wearing too short may make you hotter.

Of course, in order to ensure normal metabolism, we should also eat lean meat, fish and other foods with rich nutrition but low calorie content.

8. Don't bring metal ornaments.

Because summer itself is easy to sweat, and metal packaging can easily cause contact dermatitis if it is stained with sweat.

9. Pay more attention to rest

Therefore, we should form the habit of going to bed early and getting up early, and pay attention to preventing excessive fatigue. You can take a nap at noon, but the nap time should not be too long, and it is advisable to keep it for about half an hour. Sleeping too long will affect the central nervous system and slow down a person's metabolism, which is not conducive to health.

Newborns and babies have poor thermoregulation and heat dissipation functions, especially for those newborns, many parents have misunderstandings about heatstroke prevention of newborns and babies. For example, some parents are worried that their baby will catch cold, and they should also wrap their baby with cotton in summer. In fact, the newborn's package should be comfortable, not too thick, and the baby's hands and feet are neither cold nor hot. Other parents like to shave their babies' heads to avoid prickly heat. In fact, this will make the baby's scalp completely exposed to the sun, which is easy to damage hair follicles. So baby's hair can be cut short in summer, and there is no need to shave it.

Baby heatstroke prevention and cooling methods:

First, you can take a bath or swim to cool down. Nowadays, many places have professional baby swimming pools, so that babies can swim a few times more, which is safe and can cool down.

Second, air conditioners or fans can be used moderately. Turn on the air conditioner in the bedroom before the baby goes to bed, and then turn it off when the baby goes to bed. However, parents should never point the air conditioner or fan at their baby. The indoor temperature should be kept at about 26℃. In order to prevent dryness, parents can also put a pot of cold water in the house.

If the baby is found to have symptoms such as sweating, elevated body temperature, redness, dry skin and fever, parents should quickly move the baby to a cool and ventilated place, unbutton the clothes, wipe the baby's body with a wet towel, or fill the cold water bag to put the baby on the pillow. After the baby's body temperature drops, these measures should be lifted to avoid overcorrection.

In hot summer, it is affordable for adults, but it may cause many health problems for babies. Therefore, parents must do a good job in the baby's heatstroke prevention and cooling.

1. It is not advisable to binge drink after thirst.

After sweating a lot in labor and exercise, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be added appropriately, because too much salt is lost in the body after sweating a lot. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder.

It is not advisable to drink too much.

In summer, human body is easily affected by temperature, and excessive damp heat is the cause of skin sores, carbuncle and toxic swelling. If you drink a lot of white wine, it will contribute to dryness and dampness, which is tantamount to adding fuel to the fire.

3. Standing heatstroke prevention drugs

Summer heat, high temperature and dryness often make people eat tasteless, sleep badly, and are prone to dizziness, headache, fatigue and even nausea and vomiting. In order to spend the summer safely, families should prepare some heatstroke prevention drugs. Common medicines and foods are: ten drops of water, Huoxiang Zhengqi water, cool oil, honeysuckle, chrysanthemum, lotus leaf and watermelon.

4. Learn to have a good sleep

In summer, the days are long and the nights are short, the weather is sultry, the sleep time is short, and the sleep quality is poor. If you can take a nap in the afternoon, it is just like charging your brain, which is beneficial to your body's recovery.

5. Humidity exercise

"Life lies in exercise", but those who are old and weak and usually lack exercise should never exercise vigorously, otherwise it will be harmful and useless. It is known all over the world that the best exercise is walking.

6. Hot tea is better than cold drink.

Medical research shows that hot tea is better than cold drink in heatstroke prevention and cooling, and it lasts longer. Tea is rich in potassium. Increased sweating in summer often leads to excessive loss of potassium ions. Potassium and sodium maintain normal osmotic pressure and acid-base balance inside and outside cells, which has an important influence on nerve and muscle function, especially the normal movement of myocardium. When potassium is insufficient in the body, people often feel tired and weak, lose appetite, reduce heat resistance, and even lead to heatstroke. Drinking tea every day in summer can supplement potassium, improve heat resistance and effectively prevent heatstroke.

7. The indoor and outdoor temperature difference of air conditioner should not be too large.

The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees.

8. Wear a hat when you go out

Wear a hat when going out in summer to slow down the heat absorption of the head and neck.

9. Eat more bitter vegetables

Conducive to relieving summer heat and dampness. Bitter gourd, bitter herbs, kudingcha and bitter bamboo shoots are all excellent food for heatstroke prevention in summer.
