Science in the second year of junior high school how to prevent heat stroke .

Prevention of heat stroke In summer, the temperature is high and sweating is prohibitive, and heat stroke is most likely to occur when traveling. So, how can you prevent heat stroke when traveling in the summer?

Wear light-colored clothes When traveling in summer, you should wear white, light-colored or plain clothes, because white, light-colored or plain-colored clothes absorb heat slowly, wear cool, and are not easy to heat stroke.

The raw materials of the textile straw hat are mostly hollow, and a certain amount of air is stored in it, and the air is a poor conductor of heat. In addition, the straw hat also has a certain refractive effect on sunlight.

Rest at noon: The morning air is fresh and the climate is cool. Therefore, when traveling in summer, you should start early, rest at noon, and travel after three or four o'clock in the afternoon.

Drink more salt boiled water in summerHigh temperature, excessive sweating, and reduced salt in the body, and drinking some salt boiled water appropriately can replenish the lost salt in the body, so as to prevent heat stroke. When drinking salt water, it is necessary to drink it in small amounts and many times to prevent heat stroke.

Bring heatstroke medicine when you travel in the summer, you should bring some heatstroke medicine. Such as Ren Dan, cool oil, panacea oil, wind oil essence, ten drops of water, etc.

In the event of heat stroke, the patient should be lifted to a cool and ventilated place to lie down and rest, then unbutton the patient's clothes and apply a cold towel to the patient's head and neck. And have the patient take some rendan, or ten drops of water. If the patient faints, you can use your fingers to pinch the patient's central acupoint or acupuncture the Shixuan acupuncture points on the tips of the ten fingers of both hands.

When the patient improves, they are sent to a nearby hospital**.

To prevent heat stroke, the following should be done:

1.Pay attention to your body to cool down, don't stay outside for too long, and use an umbrella when you go out.

2.People who work outdoors, such as police officers, must find a cool place to avoid prolonged exposure to ultraviolet rays.

3.To pay attention to hydration, you can put a little salt in the water.

4.Drink more herbal tea, and you can carry a panacea and carminative oil with you in case you need it.

If you don't have such a place, wear sunscreen before you go and bring a UV umbrella to avoid strong sunlight.

Choose the shade of a tree when resting and not expose yourself to the sun.

First, drink plenty of water. In hot weather, increase fluid intake regardless of the amount of exercise you do, and don't wait until you're thirsty. For some patients who need to limit fluid intake, the amount of water they drink during high temperatures should be as directed.

Second, pay attention to salt and mineral supplementation. Alcoholic beverages and high-sugar beverages can cause the body to lose more water and should not be consumed at high temperatures. At the same time, avoid drinking frozen drinks that are too cold to avoid stomach cramps.

Third, eat less high-fat foods to reduce calorie intake.

Fourth, wear lightweight, loose, and light-colored clothing.

Fifth, try to be indoors as much as possible. If possible, the air conditioner should be turned on.

Sixth, when you go out, you should wear a UVA UVB sunscreen with an SPF value of 15 or higher, wear a wide-brimmed hat and sunglasses, or use a parasol.

Seventh, travel should be avoided around noon as much as possible, and outdoor activities should be carried out in the shade as much as possible.

Eighth, outdoor exercise should be reduced during high temperatures. If outdoor exercise is necessary, drink two to four non-alcoholic cold beverages every hour. Sports drinks can help replenish salt and minerals lost through sweat.

Ninth, if you are driving in hot weather, do not leave children and pets in the car when leaving the parking lot.

Tenth, while all populations can be affected by heat stroke, infants and young children, the elderly over 65 years of age, people with mental illness, and chronic diseases such as heart disease and hypertension are more at risk and should be of particular concern. For these high-risk groups, special attention should be paid in hot weather and timely observation for signs of heat stroke.

Heat stroke is a disorder of body temperature regulation and imbalance of water and electrolytes caused by heavy physical labor in an environment with high temperature and high humidity. In the hot summer, it is easy to have the symptoms of heat stroke, if it can not be treated in time after heat stroke, it is likely to bring great harm to the patient, so what are the first aid measures for heat stroke in summer? Let's learn about it with us!

First aid measures for heat stroke in summer

1. Immediately move the patient to a ventilated and cool place to untie his clothes and make him lie flat.

2. Apply a towel with cold water to the patient's head, and wipe the patient's body with a cool towel or fan the phoenix to help the patient cool down quickly.

3. For those with severe heat stroke, in addition to cooling down with the above methods, ice cubes can also be used to apply ice cubes to their heads, armpits and groin, etc., and if necessary, the patient can also be naked with alcohol to bathe or wrapped in sheets, and sprayed with ice water or cold water.

4. While cooling the patient, the limbs and trunk should be massaged to promote blood flow and prevent blood vessels from constricting.

5. Patients can be given drugs such as Rendan, ten drops of water or Huoxiang Zhengqi water.

6. For patients who are prostrated and unconscious, they can press or acupuncture acupuncture points such as Renzhong, Shixuan, and Shuibojianagou, and send them to the hospital for rescue in time.

How to prevent heat stroke in summer

1. When entering an air-conditioned room with a very low room temperature from a very hot environment, heat stroke is very likely to occur, so it is necessary to ensure that the temperature difference between indoor and outdoor is not too large. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees, and even if the weather is hot, the indoor temperature of air conditioners should not be below 24 degrees. Don't blow the air conditioner at yourself.

2. When you sit in a car or plane for a long time, do not replenish water in time, and the ventilation and cooling conditions are not good, it is easy to cause heat stroke, so you should prepare enough water and maintain the ventilation conditions of the environment.

3. When going out, pay attention to the use of sun umbrellas, sun hats, sunglasses and other items, and apply some sunscreen skin care products on ** to avoid direct sunlight.

4. Drink more water, and people who sweat a lot can drink light salt water. When drinking salt water, it is necessary to drink it in small amounts and many times to prevent heat stroke.

5. Wear loose clothes, cotton fabrics, and lighter colors.

6. Eat more pears, watermelons and other fruits.

7. Take sufficient rest and do not drive at night so as not to reduce the body's resistance.

What causes heat stroke

Objective reasons

Carrying out outdoor work or activities when the temperature exceeds 35 degrees Celsius without adequate heat prevention and cooling measures. In addition, although the temperature does not exceed 35 degrees Celsius, the humidity in the air is high or the ventilation is not good, which slows down the body's heat dissipation, which can also lead to heat stroke.

Subjective reasons

Frequent lack of exercise, poor physical fitness, obesity, congenital sweat gland deficiency, etc., are prone to heat stroke. Factors such as extreme fatigue, lack of sleep, loss of water and salt, wearing breathable clothing, and hunger can also cause heat stroke in healthy people. People who live in air-conditioned rooms for a long time have weak body temperature regulation and relatively poor adaptability to the outdoors.

Less exposure to people with high temperatures, high humidity, poor ventilation, or activities in the scorching sun.

In the hot summer, the temperature will gradually increase, and students will feel sweaty during indoor and outdoor classes. As a teacher, you can teach students to prevent heat stroke if you have a good knowledge of this aspect The normal body temperature of a person is generally about 36.5 degrees Celsius to 37 degrees Celsius, and this constancy of body temperature is due to the fact that the human body has a function of regulating temperature, and this function is maintained by the balance of heat dissipation and heat production If the weather is too hot, the temperature in the body is not easy to dissipate; Or exercise for a long time, the heat produced by the body increases sharply, and the body cannot release heat in time, which may cause the body temperature to rise significantly, which will cause the entire function of the body, especially the function of the brain, to be disordered, which may cause heat stroke The common symptoms of heat stroke are headache, dizziness, black eyes, palpitation, heartbeat, wheezing, thirst, nausea, ** fever, cramps, severe coma and fainting, unconscious How to prevent heat stroke? , educate students not to do physical activities at noon because the temperature at noon is high, the temperature can reach 60 degrees Celsius to 70 degrees Celsius under the sun in the open air, if students have to travel far away in hot weather or participate in sports, labor, you can wear a sunhat, wear white cotton clothes, let students increase the number of breaks during sports or in a cool place, students in the summer physical exercise, sweat a lot, the water and salt in the body will be discharged with sweat, Therefore, give students a small amount of cold boiled water with salt during the break, and students take a bath with warm water in time after exercise, which can also avoid heat stroke After mastering some sports health care knowledge, it can reduce some potential safety hazards in teaching and improve the quality of teaching

How to prevent heat stroke in summer In the high incidence season of heat stroke in the summer of the year, many people will have the phenomenon of heat stroke, in fact, as long as we usually pay attention to prevention, it will not be easy to have heat stroke. So, how can we prevent heat stroke during the hot summer months? In fact, there are many people who are worried about unnecessary, and you may not be a high-risk group of heat stroke.

1. Replenish water in time and supplement sugar for better effect

Even if you do not exercise in a hot and humid room or in a car, you will lose a lot of water and salt in your body due to heavy sweating and body temperature, which can lead to heat stroke symptoms such as cramps and coma. Everyone should pay attention to replenishing the water lost due to heavy sweating in time, and at the same time replenish sugar, the effect is better.

It is best to drink more lightly salted boiled water, mung bean soup, etc. If you need to do physical work or strenuous exercise in a hot environment, drink at least 2 4 glasses of water (500 1 000 ml) every hour. The water temperature should not be too high, and drinking water should be small and many times.

2. Pay attention to sun protection when going out in hot weather

When the temperature reaches 32, try not to go out, and if you do, arrange to go out in the morning or evening. You must bring a parasol, sunglasses, etc., and wear sunscreen with an sun protection factor (SPF) of 15 or higher (UVA UVB protection) when you go out.

3. Drink plenty of soup

In the summer, we often boil a lot of soup, such as sour plum soup, hawthorn soup, honeysuckle soup, etc., because the human body has been sweating, it will consume a lot of body fluids, resulting in a lack of water in the body, but drinking water can only replenish water, but can not replenish energy, then, drinking these soups can replenish energy at the same time, it is a good choice.

4. Use heat-insulated curtains

Insulated curtains use some special materials of fabric with special weaving technology, which can reflect light and heat, thereby reducing the temperature of the room. Moreover, the heat-insulating curtain is not see-through, and the outside cannot see the inside of the house, which is conducive to isolating heat and adjusting light, improving the effect of cold or warm room, and contributing to energy conservation and environmental protection.

5. Ventilation in the living room

The most important thing to prevent heat stroke is indoor ventilation, and never keep doors and windows closed. It is best to open the windows and ventilate in the morning or evening, and turn on the air conditioner or fan when it is hot at noon, and reduce the room temperature to about 26°C as much as possible to avoid heat stroke.

6. You can't go shirtless on a hot day

You should wear light clothing that is sweaty and breathable, rather than shirtless, because blowing directly after sweating will cause the pores to shrink rapidly, and moisture and heat will be stuffed in the body and cannot be discharged. Boys always like to be shirtless in the scorching heat, but according to the view of traditional Chinese medicine, shirtless blowing is easy to get cold, and the pores shrink rapidly, which makes the dampness and heat stuffy in the body, making it easier to suffer from heat stroke. When you feel very hot, you can gently pat the inside of your wrist with cold water to lower the blood temperature, or wipe your body with a damp towel instead of ice or shirtless.

Drink plenty of water with low salt, try to go out as much as possible in hot weather, be sure to open windows for ventilation when you are at home, and don't do some strenuous exercise.

1. Huoxiang Zhengqi water is always available at home, and you can have a can if you feel uncomfortable.

2. Mung bean soup has the effect of clearing heat and relieving heat.

3. Keep indoor air circulation.

4. Avoid going out at 2 p.m. when the sun is at its highest.

First, do not be active in the sun for a long time, and then you can take Huoxiang Zhengqi Water orally, which can effectively avoid heat stroke. Finally, you should drink plenty of water in the summer to keep your body hydrated.

Heat stroke is a dysfunction of body temperature regulation under the influence of high temperatures, often caused by exposure to the scorching sun or heavy physical labor in a hot environment.

Prevention of heat stroke should be done:

1. Pay attention to the choice of clothing. Summer clothing should be simple, thin and breathable.

2. Replenish water in time. Thirst indicates that the body is already dehydrated, so don't wait until you're thirsty to start drinking. When sweating a lot, you can appropriately supplement some light salt water.

You can also drink a little drink to prevent heat stroke, the clear and clear clear of Kang Caien solid drink is very good, usually drink a few packs, and you are not afraid of heat stroke in summer.

3. Pay attention to dietary regulation. Eat more nutritious, water-rich fruits and vegetables, such as cucumbers, tomatoes, peaches, watermelons, etc.

4. Avoid scorching sun exposure. Try not to go out between 10 a.m. and 4 p.m. on hot weather.

5. Get enough sleep. Due to the long days and short nights in summer, and the high temperature, the human body has a strong metabolism and is more likely to feel fatigue. Adequate sleep relaxes the brain and body systems, which is not only conducive to work and study, but also an important measure to prevent heat stroke.
