How to pay attention to heatstroke prevention in hot weather?

Tips for heatstroke prevention and cooling in summer

Here are some common sense of life for your reference. Please take measures to prevent heatstroke and cool down, and pay attention to your health.

First, 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.

Second, it is not advisable to binge drink after being thirsty. After sweating a lot in labor and sports, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be supplemented appropriately, because after sweating a lot, too much salt is lost in the human body, accounting for about 0.5% of sweat. 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.

Fourth, 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.

Fifth, the diet should not be too light. In summer, people have long activities, sweat a lot and consume a lot. They should eat more nutritious foods such as chicken, duck, lean meat and fish eggs to meet the metabolic needs of the human body.

Sixth, the nap time should not be too long. If 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.

Eight, air conditioning indoor and outdoor temperature difference should not be too big. 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.

Nine, it is not appropriate to 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.

In order to prevent the occurrence of heatstroke, in addition to avoiding going out from the morning to 2 pm in the strongest sunshine 10, necessary protective measures should be taken: ① keep indoor ventilation and lower the room temperature, at least with electric fans; ② Working hours at high temperature should not be too long, and should not exceed 8 hours every day; (3) Reduce labor intensity, prepare heatstroke prevention and cooling drinks, and supplement brackish boiled water or salty drinks as much as possible; Ensure adequate sleep and eat more nutritious fruits and vegetables. ⑤ Try to penetrate the air-cooled cotton-padded jacket.

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.

Soybean milk 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.

Heat-proof sleeve for special people

With the coming of the summer heat, many people with poor resistance, such as infants, pregnant women, the old and the weak, will suffer from heatstroke if they are not careful in the high temperature environment, and failure to rescue them in time may lead to tragedy. Therefore, in hot weather, these special people should take measures to prevent heatstroke and cool down.

Infants and young children: wear thin cotton and light clothes. If you sweat, dry it immediately. Try not to use electric fans or air conditioners. Before going out to play with water, you should choose a sunscreen lotion with a sunscreen coefficient lower than 15 without essence. The indoor and outdoor temperature difference should not be too large and the room temperature should not be lower than 25℃. It is best to put a basin of water in the air-conditioned room to avoid dryness.

Pregnant women: clothes should be cool and spacious, and eat more fresh vegetables and fresh bean products; Always scrub with warm water instead of taking a bath; Don't catch a cold because you are too greedy, but ensure sleep.

Old and weak: ensure no less than 7 hours of sleep every day, adjust diet to protect the spleen and stomach, don't eat more spicy food, and often eat light food; Because it is hot and sweaty, it is very important to replenish water, and at least 2500 ml of water should be added every day.

Once heatstroke occurs, you must first move out of the high temperature environment. Wipe the whole body with 40% alcohol or warm water, and apply ice packs to the superficial parts of blood vessels such as forehead, armpit and groin. In case of high fever, coma, convulsion and other serious diseases, they should be sent to the hospital for emergency treatment in time.

Some Chinese medicines should be prepared at home.

Huoxiang Zhengqi Liquid (water, pills, capsules): It mainly has the functions of relieving summer heat, detoxicating, eliminating dampness and harmonizing. Clinically, it can be used for patients with exogenous wind-cold, internal injury and dampness stagnation, manifested as cold, vomiting and diarrhea.

Ten drops of water: mainly used for headache, dizziness, nausea, vomiting and gastrointestinal discomfort caused by heatstroke. The medicine can be used to prevent heatstroke when working in long-distance travel and high temperature environment.

Ren Dan: Mainly used for heatstroke, headache, acute gastroenteritis (vomiting, abdominal pain, diarrhea), summer cold and acclimatization caused by high temperature.

Summer sickness tablet: It has the effects of relieving summer heat, detoxicating, resolving phlegm, inducing resuscitation and regulating gastrointestinal tract. It is mostly used for the first aid of coma patients with heatstroke, and can be stopped after waking up. It is not suitable for pregnant women.

In addition, Xiasangju granules, Xiahuowang granules, antiviral granules, chrysanthemum, honeysuckle and other tea substitutes brewed with boiling water have a good effect on preventing and treating summer colds and heatstroke.

Three methods for external treatment of heatstroke

Acupoints for pricking blood therapy: Xuan Shi, Qu Ze, Dazhui, Weizhong, Jinjin and Yu Ye.

Operation method: After routine disinfection, puncture and bleed with triangular needle, or add cupping to Dazhui. Mild heatstroke, a few drops of blood are squeezed out after pricking blood, and the symptoms disappear in a short time. Patients with severe heatstroke can squeeze out 0.5- 1 ml of purple-black blood every day and give them cool drinks. After acupuncture, the patient was awake for about 10 minutes, then the fever subsided and the symptoms disappeared.

Acupoint massage can treat mild heatstroke. Choose Zusanli, Dazhui, Quchi, Hegu and Neiguan, and press the acupoints with one thumb or two fingers from light to heavy, slowly and repeatedly for 3-5 minutes, depending on the degree of local acid, numbness, pain and swelling.

For severe heatstroke, in addition to the above-mentioned acupoint massage, five acupoints, Renzhong, Xuan Shi, Weizhong, Yanglingquan and Shaochong, are added, with pinching as the main method, and each acupoint is pinched for 3-5 minutes. After the above treatment, if conditions permit, giving Liangxianyin or silver needle acupuncture at the above points can enhance the curative effect.

Rubbing medicine therapy takes a handful of salt and rubs eight places, such as wrist, foot, side, front and back heart, etc. After wiping out many red spots, patients feel relaxed and recover immediately, which is suitable for threatened heatstroke or mild heatstroke.

Scientific use of "two waters"

After the summer, Huoxiang Zhengqi water and ten drops of water have almost become the necessary emergency medicines for family heatstroke prevention. If these two drugs are used rashly, it will definitely cause adverse consequences.

Huoxiang Zhengqi Water has the efficacy of relieving exterior syndrome, regulating qi and regulating middle energizer, and is mainly used to treat headache, dizziness, abdominal distension and pain, vomiting and diarrhea caused by exogenous wind, cold and internal injury and dampness stagnation. Chinese medicine believes that although the climate is hot in summer, the sudden change of weather, untimely defense or low indoor air conditioning temperature will lead to the pathogenic wind and cold. Internal injury and dampness stagnation refer to abdominal distension and pain, nausea and vomiting, bowel sounds and diarrhea caused by dampness in summer. There are more rainy days in summer, which is the season with the highest humidity in a year. Moisture invades the spleen and stomach, affecting its function and causing diseases. Modern medical research has confirmed that Huoxiang Zhengqi Water can be used for diseases such as summer cold, gastrointestinal cold, acute gastroenteritis and dyspepsia. Clinical manifestations include aversion to cold, fever, fullness of chest and diaphragm, nausea and vomiting, bowel sounds and diarrhea.

Ten drops of water have the effect of invigorating stomach and expelling wind, and are mainly used for dizziness, nausea, gastrointestinal discomfort and abdominal pain caused by heatstroke. Chinese medicine believes that when the evil of summer heat invades the human body, it will cause dizziness or headache when steam is used to clear the orifices. If the damp heat in summer makes the spleen and stomach rise and fall abnormally, and symptoms such as nausea, gastrointestinal discomfort and abdominal pain appear, you can take ten drops of water urgently. Treating heatstroke with ten drops of water is a short-term acute disease. The course of the disease is only a few minutes or hours, and 2-5 ml can be taken at the onset. Need to be reminded that because the drug ingredients contained in ten drops of water have certain toxicity, it is not appropriate to take more.

In a word, Huoxiang Zhengqi Water is mainly good at treating diseases such as summer cold and gastroenteritis caused by pathogenic wind, cold and dampness in summer, with a wide range of treatment, and can be used to treat various colds, gastroenteritis in summer and autumn, as well as gastrointestinal discomfort caused by heatstroke. Ten drops of water are only used for heatstroke, that is, dizziness, coma and gastrointestinal discomfort caused by summer heat. One medicine is mainly used to treat diseases caused by wind, cold and dampness, and the other medicine is mainly used to treat diseases caused by damp heat in summer. The curative effects of the two drugs are completely different, so we should choose according to the symptoms.
