Tips for summer life

1) water. Generally, it is "boiled water". If the family conditions are good, I have no objection to mineral water, distilled water and the like. Carbonated drinks such as cola will feel sticky in hot summer days, and if left in the mouth, it will make people more thirsty. I don't recommend them, but I don't mind that some people are really happy. In short, you must replenish water, otherwise it is easy to get heatstroke.

Moisturizing spray. If your mouth quenches your thirst, you should also keep your face. It goes without saying that facial moisturizing is very important for children. Boys sweat more and have more salt. You can spray it on your face first, and then wipe it with a towel. It's refreshing and not sticky ~ ~ ~ But a poor man like me can't afford a moisturizing spray. You can also go to Watsons to buy an empty can (the nozzle is thinner), and then go home to decorate pure water, mineral water and the like, which can be reused.

Supplement: Brothers and sisters sitting in front of the computer, it is best to spray once an hour.

4) nose soothing, wind oil essence and the like. Needless to say, everyone knows what it does. It is a necessary tool to refresh your mind when you are crowded with buses.

5) Hat or umbrella. Friends who don't want to become squid fish must bring (unfortunately ...) If gay men are afraid of coming back with umbrellas to gossip, they can choose to wear hats (they don't have to wear suits, they can only admit that they are unlucky). Of course, there are many kinds of hats to choose from when wearing casual clothes.

Of course, MM who is afraid of the sun can also apply sunscreen and sunscreen oil before going out, and it will take effect half an hour in advance. All the above are my personal "small" opinions, welcome to add and suggest.

The climate in summer is hot, germs multiply and grow rapidly, and there are many factors that affect health. So, in order to spend the summer safely, the following ten "best" in summer life can help you.

1, the best condiment-vinegar: it is cool and hot in summer, sweating more, and being jealous can increase the concentration of gastric acid, help digestion and absorption, and promote appetite. Vinegar also has strong antibacterial ability, which can kill Staphylococcus pyogenes in a short time. It can prevent intestinal infectious diseases such as typhoid fever and dysentery. In summer, people are prone to fatigue, drowsiness and discomfort. Being jealous will quickly relieve fatigue and maintain abundant energy.

2, the best vegetable-bitter vegetables: high temperature and high humidity in summer often make people listless, tired and weak, chest tightness and dizziness, loss of appetite, body weight loss. At this time, it is of great benefit to eat hard food. Chinese medicine believes that the reason why people are unhappy in summer is because the summer heat is wet, which not only hurts kidney qi but also sleepy spleen and stomach. Bitter food can balance the body function through its functions of invigorating qi, strengthening kidney, strengthening spleen and drying dampness. Modern scientific research has also proved that Sophora alopecuroides is rich in alkaloids, amino acids, picroside, vitamins and minerals, and has the functions of relieving summer-heat, relieving fever, relieving restlessness, refreshing and invigorating the stomach. Bitter gourd, bitter vegetable, lettuce, celery, dandelion, lotus seed and lily are all good choices.

2. Tips for heatstroke prevention 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 electrolytes. Drinking too much will have adverse effects on 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. To prevent heatstroke, in addition to trying to avoid going out during the period of the strongest sunshine from 10 to 2 pm, 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. A good drink in summer is hot tea. What kind of drink is better? 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. In summer, people sweat a lot and consume a lot of energy. People generally lose weight to varying degrees. On the one hand, it is necessary to relieve summer heat, on the other hand, nutritional supplement is also very important. 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. There is also a kind of soybean milk: lily lotus seed pulp.

Materials: lily 10g, lotus seed meat 10g, tremella10g; 45g mung bean, crystal sugar or honey. Methods: dried lily and lotus seed meat were soaked in warm water until soft; White fungus is boiled with water, washed and picked into small flowers; Soak mung beans fully, wash them with lily, lotus seeds and tremella, put them into the net cover of soybean milk machine, inject appropriate amount of water into the cup, and install the machine in place.

Start the machine, and after ten minutes, the soybean milk with red dates and lotus seeds will be ready. You can add sugar or honey to the cup while it is hot according to your personal preference and stir it evenly.

The summer heat is coming. For special people, many people with poor resistance, such as infants, pregnant women, the elderly and the infirm, will suffer from heatstroke if they are not careful in a high temperature environment. If they are not rescued in time, it 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:

3. Tips for heatstroke prevention and cooling in summer

The summer climate is hot and there are few natural winds. Chickens have poor adaptability to high temperature because they are full of feathers and have no sweat glands. Relatively speaking, chicks can tolerate high temperature, while middle-aged chickens, especially large chickens, have low tolerance to high temperature. Pay attention when the indoor temperature reaches 32℃; If it exceeds 35℃, problems may occur. A little carelessness in summer will cause losses, so we should do a good job in heatstroke prevention and cooling. For details, please refer to the following measures:

(1) Reduce the radiation heat and reflection heat suffered by the henhouse: white paint can be painted outside the roof to increase the thermal reflection, which can generally reduce the temperature1~ 2℃; When the weather is very hot, you can also spray water on the roof, so that the temperature of the house will drop by about 3℃. Grass should be planted around the henhouse to prevent the ground from reducing heat reflection; At the same time, the grassland evaporates a lot of water vapor, which makes the air moist and plays a role in dust prevention and cooling.

(2) Increase the ventilation rate and airflow speed in the shed: all doors and windows should be opened in the open chicken coop, and electric fans can be installed when there is no natural wind to speed up the air flow in the shed. It is best to change the closed henhouse into longitudinal ventilation and adopt axial fan with low speed, low static pressure and large flow. Wet curtain cooling technology can be used to further reduce the indoor temperature where conditions permit.

(3) The henhouse building uses materials with good thermal insulation performance: materials with low solar heat absorption rate are selected for the roof surface, and generally speaking, black materials have high solar heat absorption rate. To design a good roof slope, the roof slope is closely related to solar radiation heat. Generally, the slope is 3∶ 10, but when designing plastic greenhouses, the slope should absorb solar radiation heat to the maximum extent, and vice versa.

(4) Adjustment of feeding management: The feeding density should be appropriately reduced in summer. To improve the level of protein in diet, it is necessary to use some high-quality raw materials, such as imported fish meal and amino acids. Eat at night and in the morning. Providing cool drinking water is very effective in lowering the body temperature of chickens. Vitamin C and other electrolytes can be added to drinking water when necessary to reduce the influence of heat stress.

4. Summer heatstroke prevention tips poem

First, eat more fruits and vegetables in summer.

1

Cucumber: Eating cucumber often helps to lose weight. Wash cucumber as a snack, eat more than 250 grams raw every day, and lose weight obviously; Cucumber can induce diuresis and eliminate edema. Eating cold food can increase appetite and reduce bloating. Cucumber can also quench thirst and heat.

Bitter gourd: Bitter gourd contains protein, fat, sugar, calcium, phosphorus, iron and other substances. In particular, momordicin has high medicinal value. It can secrete saliva and gastric juice, enhance appetite, lower blood sugar and eliminate polydipsia. It is a good product for relieving summer heat. Watermelon: It is rich in fruit juice, with a sugar content of over 95%. It can not only induce diuresis to quench thirst, but also clear away heat and relieve summer heat. Besides being rich in sugar, it also contains more organic matter, amino acids and inorganic salts than other melons. In hot summer, it is a good product for supplementing water and nutrition, lowering blood pressure and treating nephritis.

Wax gourd: contains a variety of trace elements necessary for human body, but does not contain fat. Contains propanedioic acid, which can inhibit the conversion of sugar into fat, prevent fat from accumulating in human body, and has the function of reducing fat and blood lipid. Once people suffer from heatstroke, fever and dizziness, 500 grams of wax gourd can be used to cook soup, three times a day, each time 1, a large bowl, and the effect is obvious. Wax gourd is cut into small pieces, and rubbing prickly heat is very effective. Wax gourd 1 000g, carp1boiled soup will be fine.

Second, the "Top Ten" of Summer Heatstroke Prevention

1, the best condiment-vinegar: In midsummer, people have a poor appetite. Being jealous can increase the concentration of gastric acid, help digestion and absorption, and promote appetite. In summer, people are prone to fatigue, drowsiness and discomfort. Being jealous will quickly relieve fatigue and maintain abundant energy.

2, the best vegetable-bitter vegetables: high temperature and high humidity in summer, often make people listless, tired and weak, loss of appetite. At this time, it is of great benefit to eat hard food. Bitter food can balance the body function through its functions of invigorating qi, strengthening kidney, strengthening spleen and drying dampness. Modern scientific research has also proved that Sophora alopecuroides is rich in alkaloids, amino acids, picroside, vitamins and minerals, and has the functions of relieving summer-heat, relieving fever, relieving restlessness, refreshing and invigorating the stomach. Bitter gourd, lettuce and celery are all good products.

3, the best soup-tomato soup: drink more tomato soup in summer to get nutrition, but also replenish water, kill two birds with one stone.

5. Common sense of summer life

With the approach of summer heat, the number of patients with cold, fever, headache, gastrointestinal discomfort and upper respiratory tract infection in hospitals has gradually increased, and some elderly people have also induced cardiovascular and cerebrovascular diseases.

Heatstroke is a common acute disease in summer. Generally speaking, there are three reasons for heatstroke: first, the room is too stuffy, and the elderly and patients are more prone to heatstroke; Second, they stay in the hot sun for too long, such as some outdoor workers; Third, people who work in high temperature environment. First aid: First, take the heatstroke victim to a ventilated and cool place, let him lie flat, unbutton his clothes, apply a cold towel on his head to cool down, and if possible, feed him some salty drinks or Ren Dan, essential balm and other summer medicines.

If you are indoors, immediately open the window for ventilation, or blow it with an electric fan. Those who still can't get better should be sent to the hospital.

How to prevent heatstroke and cool down? In this hospital, experts provide some summer heatstroke prevention tips to help you spend the summer: First, strenuous outdoor and daytime activities such as mountain climbing are not recommended in summer, and sports activities such as swimming and jogging are recommended in the morning and evening. Second, drink more boiled water and drink water regularly. Don't wait until you are thirsty. It is not advisable to binge drink after thirst.

Drink less fruit juice, soda and other drinks, which contain more saccharin and electrolyte. Drinking too much will have an adverse effect on the gastrointestinal tract, affecting digestion and appetite. Third, 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. Fourth, 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, fish and eggs to meet the needs of human metabolism. 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.

Fifth, 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.

Sixth, 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.

Seven, 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.

Eight, should not wear metal jewelry. Some metals in metal ornaments are contaminated by sweat, and the skin may be red or itchy, which may easily lead to contact dermatitis.

9. Remember to prepare sunscreen equipment when you go out in summer. It is best not to walk in the hot sun from 10 to 4 pm. If you must go out at this time, you must take good protection, such as umbrella, sun hat and sunglasses, and it is best to apply sunscreen.

Ten, daily life should be regular, do not often stay up late, to ensure adequate sleep is also an effective measure to prevent heatstroke. Be careful not to lie under the air conditioner outlet and electric fan when sleeping.

Eleven, go out to carry heatstroke prevention and cooling drugs, such as ten drops of water, Ren Dan, essential oil, etc. In case of emergency. The efficacy and pharmacology of Huoxiang Zhengqi Pill (water and powder) for heatstroke prevention in summer are basically the same.

The main ingredients are Radix Angelicae Dahuricae, Pericarpium Citri Tangerinae, Rhizoma Pinelliae, Cortex Magnolia Officinalis, Poria and Pericarpium Arecae. Atractylodes macrocephala, Platycodon grandiflorum and Glycyrrhiza uralensis Fisch. The aqua contains Folium Perillae, Radix Glycyrrhizae extract and Rhizoma Atractylodis. It has analgesic, antibacterial and antiseptic effects.

In summer, patients with exogenous wind-cold benefit most from this medicine. Second, the main components of Ren Dan are mint water, talc, catechu, clove, woody incense, fennel, Amomum villosum, dried tangerine peel, etc.

It has the effects of clearing away heat, relieving summer heat, removing filth and stopping vomiting, and is a commonly used medicine for heatstroke prevention in summer. Mainly used for headache, dizziness, nausea, abdominal pain, acclimatization and other symptoms caused by high temperature.

This medicine can promote intestinal peristalsis and relieve intestinal spasm. Heat stroke, acute gastroenteritis, and cough with excessive phlegm should be reused.

Three, ten drops of water are mainly composed of camphor, rhubarb, ginger, clove, pepper, dried tangerine peel and so on. Has the effects of dispelling summer heat, dispelling cold and invigorating stomach.

Modern medical research believes that it is mainly used to treat various symptoms caused by heatstroke. At the same time, it can also be used externally to treat miliaria or mild skin injury.

Fourth, Liuyi Powder is composed of two kinds of drugs, namely talc and incense. It has the effect of clearing away summer heat and benefiting the stomach.

It has a good curative effect on people who are upset and thirsty, have short yellow urine or vomit and diarrhea, but it is contraindicated for people with yin deficiency and no damp-heat and pregnant women. Knowledge of heatstroke prevention and health care measures: 1, to provide necessary salty or sour drinks for producers engaged in livestock and poultry breeding in summer; 2, timely distribution of Ren Dan, ten drops of water, essential balm and other heatstroke prevention drugs.

Second, the symptoms of heatstroke and first aid methods A, symptoms of heatstroke 1, threatened heatstroke: a lot of sweating, thirst, dizziness, tinnitus, chest tightness, palpitations, nausea, elevated body temperature, general weakness. 2. Mild heatstroke: In addition to the above symptoms, the body temperature is above 38 degrees, facial flushing, chest tightness, pale face, nausea, vomiting, sweating, cold skin, blood pressure drop and other early symptoms of respiratory and circulatory failure.

3. Severe heatstroke: In addition to the above symptoms, there are also symptoms such as syncope and spasm, dry skin and no sweat, and body temperature above 40 degrees. B, emergency measures after heatstroke 1, quickly transplant heatstroke patients to a cool and ventilated place; 2. Take off or loosen the clothes and let the patient rest on his back; 3. Give patients cold drinks containing salt or cold boiled water containing 0. 1%-0.3% salt; 4. Wipe your body with cold boiled water or alcohol; 5. People suffering from severe heatstroke should be sent to hospital immediately for rescue.

6. Safety knowledge in summer

In summer, stored rice noodles are easily affected by insects. You can use two handfuls of pepper and fennel, wrap them in gauze and put them in a jar full of rice. Cover the cylinder head tightly, and the stored rice noodles will not be easily eaten by insects. In summer, the raw meat bought back can be wrapped in a wet cloth dipped in vinegar, which can keep fresh for a day and a night. In summer, soy sauce goes bad easily. Peel a few cloves of raw garlic and put them in a bottle. Soy sauce is neither moldy nor smelly. When cooking lard in summer, cut raw radish into two or three pieces and put it in an oil container before putting the oil, so that there will be no strange smell. In summer, putting food in a porcelain bowl and then cooking it in a pressure cooker can keep it unchanged for 3-4 days. In summer, if the bought tofu turns sour, soak it in 50% hot alkaline water for 20-30 minutes, and then rinse it with clear water to remove the sour taste. In summer, if you buy vegetables with bugs, you can soak them in salt water for a while, then rinse them with clear water to wash them all off. When cooking in summer, vinegar is added to 1.5 kg rice according to the ratio of 2-3 ml, and the cooked rice is not easy to deteriorate and has no vinegar taste. Tea leaves are moldy in summer, so it is forbidden to bask in the sun. Bake in a pot for about 10 minutes, and the taste will be restored. But the pot should be clean, and the fire should not be too big. In summer, white underwear tends to turn yellow after washing. You can take a basin of clear water, drop 2-3 drops of blue ink, soak the washed underwear for another quarter of an hour, and dry it in the sun without wringing it out, so that the washed clothes are white and clean. New vests and undershirts bought in summer are washed with boiling water before wearing, which is wear-resistant and does not fade; But chemical fiber fabrics should not be scalded with water. Foam sandals newly bought in summer are not easy to crack and wear after being soaked in salt water for a long time and dried. Using loofah as insole can remove moisture from rubber-soled shoes. Put a few pickled sweet and sour garlic under the bed in summer to drive away bedbugs. The climate in summer is hot, the germs multiply and grow rapidly, and there are many factors that affect health. So, in order to spend the summer safely, the following ten "best" in summer life can help you.

Heatstroke is one of the common diseases in summer, mainly due to the imbalance of body temperature regulation in high temperature environment, which makes the body store a lot of heat, causing water and salt metabolism disorder, thus causing heatstroke. The normal body temperature of the human body is maintained at 36℃-37℃, which is because the human body has the ability to automatically adjust the body temperature, so that heat generation and heat dissipation are always in a balanced state. The temperature is high, the humidity is high, and there is no ventilation, so the accumulated heat in the body is not easy to dissipate, so the accumulated heat in the body is more and more; Coupled with excessive sweating, a large number of water loss and salt loss, resulting in imbalance of human regulatory function, will lead to heatstroke. Some people are too tired because of lack of sleep and improper rest arrangements in summer; As well as old age, infirmity, excessive drinking and other factors, can make the human body unable to adapt to the external high-temperature climate, create obstacles in the kinetic energy of body temperature regulation, and make the body temperature rise continuously, thus leading to the occurrence of the disease. Heatstroke is generally divided into three types: threatened heatstroke, mild heatstroke and severe heatstroke. Symptoms of threatened heatstroke include increased sweating, dry mouth, general fatigue, dizziness, palpitation, chest tightness, nausea and inattention. Mild heatstroke is more serious than threatened heatstroke. In addition to the symptoms of threatened heatstroke, there are also symptoms such as elevated body temperature, burning skin, flushing, sweating, nausea and vomiting, slight drop in blood pressure, dizziness and so on. Severe heatstroke shows as follows: the body temperature rises obviously, reaching 40℃ or even higher, suddenly fainting and falling to the ground, and being unconscious; Hand-foot spasm, dry skin or sweating, and sudden drop in blood pressure are often life-threatening if not rescued in time. So once you find heatstroke, you should take timely measures and actively treat it. For patients with threatened heatstroke and mild heatstroke, first help them to a cool and ventilated place, unbutton their clothes, put a cold wet towel on their heads, and let them drink more salty and cold drinks. People with dizziness, nausea and vomiting can take ten drops of water, Ren Dan or Huoxiang Zhengqi water. Patients with severe heatstroke should be taken to the shade as soon as possible for on-site rescue, and should be sent to the hospital immediately without delay. Pay attention to prevent heatstroke. Personnel working in the open air or high temperature environment must take protective measures to reduce direct thermal radiation and strengthen ventilation; Arrange daily life scientifically, pay attention to the combination of work and rest, and ensure adequate sleep. At the same time, pay attention to nutrition, eat more vegetables and fruits, prepare enough cool drinks such as cold boiled water, mung bean soup and sour plum soup, as well as ten drops of water, cool oil and essential oil. Once you have symptoms of heatstroke, you should take it in time.

7. Popular science knowledge should be as simple as 100 words.

1 Weather refers to meteorological phenomena that occur in a short time (from several minutes to several days), such as thunderstorm, hail, typhoon, cold wave and strong wind.

2. What is climate climate refers to the long-term average of various meteorological elements in a long period (month, season, year, year, even hundreds of years, etc.). It is a comprehensive reflection of the basic characteristics of cold, warm, dry and wet weather conditions in a region.

3. Climate resources Climate resources refer to natural substances and energy widely existing in the atmosphere, such as light energy, heat energy, precipitation and wind energy. , can be directly or indirectly used by people, forming wealth, with use value. It is a very precious renewable natural resource and the basic condition for the survival and development of human society, and has been widely used in all aspects of the national economy and people's livelihood.

4. Microclimate Microclimate is a unique climate in local areas under the same climate background, which is caused by the inconsistency of terrain orientation, soil conditions and vegetation. The characteristics of microclimate are mainly manifested in the drastic changes of individual meteorological elements and the differences of individual weather phenomena.

Urban climate is a local climate or microclimate formed under the macro-climate or regional climate background due to the influence of urbanization. The urban climate is characterized by five islands, namely, heat island, wet island, dry island, rainy island and mud island.

6. Heat island effect Heat island is a comprehensive phenomenon of microclimate change caused by people changing the urban surface, and it is one of the most obvious characteristics of urban climate. Due to the acceleration of urbanization, dense urban buildings, asphalt roads and cement pavements have greater heat capacity and heat absorption rate than the soil and vegetation in the suburbs, which makes the urban area store more heat and radiate it to the surrounding areas and the atmosphere, resulting in the temperature in the urban area being generally higher than that in the surrounding suburbs at the same time. The high-temperature urban area is surrounded by low-temperature suburbs, just like an island in the sea of Wang Yang. This phenomenon is called urban heat island effect.

7. Why the air pressure in winter is higher than that in summer refers to the pressure produced by the air column per unit area on the earth. The air pressure in a place often changes. When the air pressure drops, it is rainy, the weather rises and the weather turns fine. There are many reasons for the change of air pressure. The change of temperature is a very important reason for the change of pressure. When the air is cooled, the air contracts, the density increases, the weight of air column per unit area increases, and the air pressure also increases. Therefore, the arrival of cold air is always accompanied by the increase of air pressure; When warm air comes, the air pressure tends to drop. Winter is a world of cold air and summer is a world of warm air, so obviously, the air pressure is high in winter and low in summer.

8. Encyclopedia of scientific knowledge (30 words)

Scientific common sense in life:

1. Why does sorbet get angry?

The reason why sorbet bubbles is because there is a lot of invisible water vapor in the outside air. When it comes to cold sorbet, it will liquefy into droplets when it is cold. It seems that the sorbet is bubbling.

2. Why do sunflowers always face the sun?

Sunflower stems contain a wonderful auxin. This auxin is very afraid of light. When it is illuminated, it will go to the backlight side, and the cells on the backlight side will multiply rapidly. Therefore, the backlit side will grow faster than the bright side, which will bend the sunflower to light.

3. Why do cicadas shed their skin?

Cicada's shell (exoskeleton) is hard and can't expand with the growth of cicada. When the cicada grows to a certain stage, the cicada's exoskeleton restricts its growth, and the cicada loses its original exoskeleton, which is cicada slough.

4. How do bees make honey?

Bees spit the collected sweet flower juice into an empty beehive. At night, they suck sweet juice into their honey stomachs to make it, and then spit it out and swallow it. It takes 65,438+000 ~ 240 times to make sweet honey.

5, hanging on the wall of the quartz clock, when the battery runs out and stops, its second hand often stops at the "9" position on the dial. This is because the second hand is most hindered by the large torque at the "9" position. Scientific common sense

6. Sometimes, when tap water flows from the adjacent faucet, it occasionally makes bursts of noise. This is because the water pipe vibrates when the water rushes out of the tap.

7. When taking pictures on TV, turn off the camera flash and indoor lighting to make the picture clearer. Because the reflected light of the flash lamp and the illuminating lamp on the TV screen will interfere with the transmitted light of the TV picture.

8. At the same temperature, frozen meat thaws faster in water than in air. At the same temperature, hot nails cool faster in water than in air. A cup filled with boiling water cools faster when immersed in water than when immersed in air at the same temperature. All these phenomena show that water has better heat transfer performance than air,

9. When there is cold water in the pot, the water droplets attached to the outer surface of the pot bottom can only be dried up after a long time on the flame, and will only boil when it is dried up. This is because the water droplets, the pot and the water in the pot keep heat conduction, and the temperature is almost the same.
