It's too hot. How can we dissipate heat? It has a great influence on our body and mind. Generally, we will use air conditioning to cool the surrounding temperature, but we can't stay in such conditions for a long time. Here's how to dissipate heat when it's too hot.

How to dissipate heat when it's too hot? One trick: drink hot tea, eat hot food and soak your feet in hot water.

Summer heat is the main qi in summer. Summer heat is transformed from fiery qi. Excessive summer heat is harmful to the body and causes disease, which is summer evil.

Summer evil is often manifested as a series of symptoms of yang heat, such as high fever, upset, red face, irritability and heavy pulse, which is called summer injury (or summer heat).

Summer heat is yang evil, not yang. Therefore, the invasion of summer evil into human body is more direct and popular, which can lead to phlegm-heat sweating.

In summer, the climate is not only hot, but also often rainy and humid, with heat steaming and dampness, and damp heat permeates the space. Everything people touch and breathe cannot be separated from damp heat.

Summer is better than humidity, and there must be more feeling. Therefore, in this season, many people often feel sleepy, chest tightness and nausea, and even diarrhea, in addition to symptoms such as fever and polydipsia.

How to reasonably cool off the summer heat? People often think of cold drinks, cold showers, air conditioners and so on.

However, this antagonistic method of cooling off summer heat does not conform to the principle of health preservation.

Physiologically speaking, skin is the main channel for human body to dissipate heat. When the outside temperature is lower than the skin temperature, radiation, conduction and convection are the main ways to dissipate heat.

When the outside temperature is higher than the skin temperature (33℃), sweating becomes the main way to dissipate heat.

In summer, the temperature is often above 30℃, sometimes as high as 38℃, so sweating becomes the main or only way to dissipate heat.

At this time, if you suddenly encounter cold stimulation, the pores will close quickly and the blood vessels will suddenly contract, which will easily lead to a cold.

Or the accumulation of cold pathogens, the future onset, and even can induce serious cardiovascular and cerebrovascular diseases.

For the digestive system, eating cold suddenly hurts the spleen and stomach, leading to a decrease in appetite.

In addition, it leads to gastrointestinal dysfunction, abdominal pain and diarrhea, which is also the most common cause of gastrointestinal colds in summer.

Therefore, the method of cold heating is not desirable. Instead, it is necessary to properly maintain or increase sweating to achieve good heat dissipation, which is called "heating with heat".

Therefore, it is more appropriate to drink hot tea and eat hot food in summer.

In summer, the yang is floating outside, and the human body is weak inside and cold outside. There is also a folk proverb "eat radish in winter and ginger in summer".

Therefore, in summer, we should properly choose warm food and drink hot tea to provide enough energy for the human body, so that sweat glands and pores can fully sweat, so as to better dissipate heat.

Similarly, taking a hot bath and soaking feet with hot water can also promote sweat gland secretion, enhance metabolism and accelerate heat dissipation.

Tip 2: Exercise properly until you sweat.

Proper exercise can produce hot sweat, improve the function of body temperature regulation, enhance the heat resistance of human body, and also enhance physical fitness and prevent heatstroke.

Summer exercise should try to avoid hot noon, and choose morning or evening as appropriate. Fitness programs can choose swimming, walking, jogging, Tai Ji Chuan, Baduanjin and so on.

It should be noted that water should be replenished in time during exercise and sweat should be dried in time after exercise. Don't take a cold shower or blow air conditioning immediately after exercise.

Of course, the more sweat, the better. Everything is moderate. Traditional Chinese medicine pays attention to the concept of "too much is too late", and excessive sweating also has corresponding disadvantages.

"Sweat and blood are homologous", the summer climate is hot, a little exercise can lead to sweating, but excessive sweating often leads to a series of discomfort.

Hyperhidrosis damages body fluids, and fluid loss may lead to thirst, dry mouth and short urine. When sweating heavily, qi is often discharged with body fluid, leading to qi deficiency.

Therefore, people suffering from heatstroke often have shortness of breath and fatigue, and even suddenly faint and become unconscious.

Tip 3: slimming soup can prevent heatstroke.

Recommend several Chinese medicines or dietotherapy methods that can be properly matched in summer to relieve heat and heatstroke:

Plum syrup

It has the functions of promoting fluid production to quench thirst, stimulating appetite and promoting digestion, and is a good summer product.

Ingredients: ebony, hawthorn, licorice, rock sugar.

Shengmaiyin

A Chinese medicinal formula for relieving summer-heat, especially suitable for people with excessive sweating and thirst.

Ingredients: Radix Ophiopogonis, Fructus Schisandrae Chinensis, and Radix Codonopsis, which can replace tea. For those who sweat a lot and are prone to repeated colds, Radix Astragali and Radix Saposhnikoviae can be added as appropriate.

Huoxiang Zhengqi water

It is a common Chinese patent medicine. The hot and humid climate in summer often causes gastrointestinal colds. Huoxiang Zhengqi Water is a specific medicine for gastrointestinal cold in summer, and children can also use medicated bath.

In addition, lotus leaves, mung beans, watermelon and Cui Yi all have good summer-heat relieving effects, and when used in porridge or soup, they are a good summer-heat relieving dietotherapy method.

How to dissipate heat when it's too hot? Eight skills of cooling in hot weather.

First of all, mint leaves are summer artifacts.

In fact, in the heat, our bodies can also feel cool, and it is mint that makes this cool. What makes people feel "cool" in mint is a substance called menthol, which can directly activate the cold receptors on the skin and produce a feeling similar to that under low temperature conditions. In fact, the physical temperature of the body has not decreased at this time, and people just feel a comfortable "cool" meaning.

Mentha and other ingredients make people feel cool, generally superficial or partial, which is very suitable for those who are both "greedy for cold" and "afraid of cold".

Second, hug the melon to sleep

Holding wax gourd to enjoy the cool is a folk law that has been circulating for a long time to cool off the summer. Wax gourd is used to cool down, which makes sense. The principle is that its water content is as high as 96%. It is cold because of its high water content. Wax gourd has high water content, which is beneficial to cooling, just like cooling with a water pillow. The skin of winter melon is cool, which has the function of clearing away heat and relieving summer heat.

Ye, a famous doctor in Qing Dynasty, recorded in the book "Herbal Rejuvenation" that the skin of winter melon has the functions of "peeling, dehumidifying and chasing wind, invigorating spleen and purging fire". Winter melon is called "winter melon" because its skin has a layer of white powder, which looks like winter frost, so it is named, but literally, it also hides the meaning of coolness.

Although the method of cooling wax gourd is simple and practical, it is not suitable for everyone. If it is a hot constitution, cooling is no problem. If it is cold constitution, such as yang deficiency constitution, spleen and stomach weakness, pregnant women and the elderly, it is best not to use this method to cool down, so as not to be hurt by the cold of winter melon skin.

Third, drink a bowl of sour plum soup.

Sour plum soup is a traditional summer drink. In the hot season, it is feasible to drink chilled soup to eliminate blood stasis, promote fluid production to quench thirst, inhibit lung qi, eliminate troubles and soothe the nerves. In addition, sour plum contains a special kind of citric acid, which can effectively inhibit lactic acid. When you are tired in summer, drinking a cup of sour plum soup can play a good refreshing role and revitalize muscles and blood vessels.

The raw materials of sour plum soup are ebony, hawthorn, osmanthus, licorice and other materials. The ratio of enucleated ebony to hawthorn is 3: 2, and then a portion of licorice is prepared. After boiling water on high fire, turn to low fire and cook for about 40 minutes. Add appropriate amount of rock sugar to taste according to taste, and then take it out of the pot. Drinking it after cooling or refrigeration is very effective for relieving summer heat and stimulating appetite.

Fourth, the mentality is peaceful and natural.

Peace of mind is natural and cool. In order not to be impatient in the sultry summer, the key is to keep a calm heart, just as the poet Bai Juyi said, "How to get rid of the summer heat and sit in the hospital?" There is no length in front of you, and there is a breeze under the window. "Of course, there are still many ways to cool off the heat: have a cup of tea and watch the wind light and the clouds light; Find a touch of green and smell the birds and flowers; Immerse yourself in the fragrance of one room and enjoy the spring breeze of ten miles ... Let your leisure flow in your own world.

When the weather is sultry, you should take part in social activities such as large-scale parties as little as possible, and increase the time for a person to be alone or have a quiet rest, which can effectively reduce the chance of "emotional heatstroke". When it is hot, try not to talk about topics that stimulate others, and choose topics that are relatively relaxed and pleasant. We should also pay attention to guiding children not to be too serious, to be open-minded and tolerant of others.

Five, the fan gently shaking

Feather fan shaking is a wise man's choice to cool off the heat. Although the fan is an "antique", the fitness effect is unmatched by any cooling equipment. Shake the fan to exercise the limbs (shaking the fan with the left hand can activate the right brain, develop the potential of the right brain and prevent stroke accidents). At the same time, fans got the most comfortable wind.

Rocking fan is a kind of unilateral limb exercise, which can not only exercise the joint muscles of limbs, but also exercise the contraction and relaxation functions of cerebral vessels. The results showed that most stroke patients suffered from microvascular rupture and bleeding in the right hemisphere, while most middle-aged and elderly people suffered from brain atrophy in the left hemisphere. This is because most people are used to using their right hand for a long time, and their left hand exercises less, which leads to more exercise in the left hemisphere and less exercise in the right hemisphere.

Therefore, you should consciously shake your left hand in summer. By strengthening the left hand movement, the right brain can be activated, the flexibility of the left limb and the atrophy of the body can be improved, the elasticity of the blood vessels in the right hemisphere can be enhanced, and the occurrence of cerebrovascular diseases can be reduced.

6. Mung bean soup is summer soup.

Mung beans are sweet and cool, which can clear gallbladder and nourish stomach, relieve summer heat and quench thirst. In the hot summer, mung bean porridge is an ideal summer-heat agent. It is best to directly boil mung bean soup with pure water. If not, add half a spoonful of white vinegar or squeeze half a spoonful of lemon juice into the water, but be careful not to add too much.

The specific method is to boil water first, then add mung beans, cover and continue to cook for 8- 10 minutes. Pour out the clear soup, so that the boiled mung bean soup can remain green in the air for a long time, and the effect of relieving summer heat is good. The remaining beans can be boiled into green bean paste or cooked with rice into mung bean porridge.

What needs special reminder is that you must never use an iron pot to cook mung beans. Because iron can catalyze the oxidative decomposition of various vitamins, the tannin in mung bean skin reacts with iron at high temperature and becomes black iron tannin, which makes mung bean soup black and affects the detoxification effect of mung beans, which is harmful to human body. When cooking mung bean soup, you can use casserole, stainless steel pot or special saucepan.

daydream

It's too hot, you might as well sit and have a rest, close your eyes and take a nap. Studies have shown that one of the body's reactions to daydreaming is to lower the body temperature. Do you need me to teach you? Who doesn't want to go to an island with fantastic scenery for a holiday in the sultry summer? You can imagine yourself lying under a coconut tree on the beach, staring at the blue sea in a daze, or jumping into the cool sea to swim.

Eight, take a hot bath

It's best to take a hot bath in summer. When people soak in warm water, the pores will open quickly and the heat in the body will be released. Through repeated soaking, the sweltering heat in the body can be completely eliminated and the symptoms can be cured. On the contrary, if people soak in cold water directly, the stimulated pores will close immediately. Although the skin will feel cool, the heat in the body can't be completely discharged, and it will still feel very hot after a while, which can't really cool down.

How to prevent heatstroke and cool down in hot weather

First, diet: replenish water in time and avoid eating cold drinks.

The temperature is high in summer, and the human body volatilizes a lot of water. Everyone knows to replenish water in time, but thirsty people should avoid drinking too much water. Drinking water like this will make it difficult for the stomach to adapt and cause adverse consequences.

Summer is the season to eat cold drinks, but in fact, the colder you eat, the easier it is to get heatstroke. Because of the rapid drop of local temperature in human body, it will make human body unable to adapt to such rapid temperature change at once, and the digestive system will be affected, which will further affect the normal operation of various systems in the whole body and easily lead to heatstroke. Moreover, hot tea can help the human body to adjust the imbalance caused by high temperature, play the role of heating with heat, and is a good heatstroke prevention drink.

Eat more melons in summer, because most melons can clear away heat and promote diuresis, help eliminate toxins, and are good food for cooling and heatstroke prevention. For example: cucumber, towel gourd, bitter gourd, wax gourd and so on. They are foods with the highest water content, rich in minerals and vitamins, and can effectively replenish a lot of water lost in summer. At the same time, they contain almost no fat and have low energy, and most of them have the functions of lowering blood fat and blood sugar.

In addition to eating vegetables rich in vitamin C such as celery, lily, tomato and cucumber, you should also eat bitter food such as bitter gourd and turtle paste, which is helpful for diuresis, dampness elimination, anti-inflammation and fever reduction.

Second, heatstroke prevention and cooling: the protection work should be done, and the air conditioner should not be turned too low.

Pay attention to shading and cooling when going out, choose natural fabric clothes with good breathability and light texture, and don't go shirtless. It is best to wear loose long-sleeved trousers for a long time in the hot sun to avoid sunburn. Be prepared for sun protection when going out, wear sunglasses, a sun hat or use a sun umbrella.

Old people had better be accompanied by their families when they go out. 12 From noon to 2 pm, the sunshine is the most abundant, so try not to stay outdoors. Hot, sultry rooms and open spaces should try to avoid staying for a long time, which is easy to cause heatstroke.

When choosing sports, strenuous outdoor and daytime activities such as mountaineering are not recommended in summer, and sports activities such as swimming and jogging are recommended in the morning and evening. When exercising outdoors, you should prepare heatstroke prevention drugs, including: Huoxiang Zhengqi Water, Ten Drops of Water, Ren Dan, etc.

In addition, if you are in go on road trip, you must turn on the air conditioner and windows in the car before you leave, so that the air in the car can circulate, and then you can enter the car. Try not to close the window 3 minutes before you start walking, and give some time for the air in the car to come out.

Air conditioning is a good helper to cool down in summer, but don't set the air conditioning temperature too low. If the temperature difference between indoor and outdoor is too large, it will also lead to heatstroke. Keep the room and office ventilated, but don't turn on the air conditioner and fan. The air conditioner should be kept above 26℃ during the day and 28℃ when sleeping.

In summer, physical strength loss is relatively faster under high temperature, so we should pay attention to reasonable arrangement of work and rest time to ensure adequate sleep. At noon, citizens with conditions can choose to take a break to replenish their physical strength, be careful not to overwork physical labor, and pay attention to slowing down outdoor work.

Third, heatstroke: first cool down and send it to the doctor as soon as possible.

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 seek medical treatment in time.

For patients with heatstroke, the following four emergency measures can be taken:

1, quickly move the patient to a ventilated and cool place, let him lie flat, unbutton his clothes and raise his feet, which will help to increase blood supply to the patient's brain and play a role in heat dissipation.

2. Cover the patient's forehead with a cold towel, wipe the whole body with alcohol or cold water if possible, and then blow with a fan or electric fan to accelerate heat dissipation. However, we should pay attention to moderation. When the patient's body temperature drops below 38℃, forced cooling methods such as blowing and pouring cold water should be stopped.

3. Patients should add salt or baking soda to cool drinks, and don't drink coffee or alcoholic drinks. If the patient has lost consciousness, he can restore consciousness by pressing Renzhong and Hegu points.

4. Patients with severe heatstroke should be sent to hospital immediately for treatment.

Tips for heatstroke prevention and cooling

First, open doors and windows reasonably.

Many people think that when the temperature is high in summer, all doors and windows should be opened to cool down. In fact, this idea is wrong. For example, during the day, the outdoor temperature is much higher than the indoor temperature itself. At this time, if you open the doors and windows at home, it will let in the hot air outside, which is not conducive to cooling down.

Therefore, if you can choose to open the window in the morning and evening, it will not only help to circulate the air, but also help to "drive away" the hot air inside the house and let the cool wind outside come in. Therefore, it is best not to open the window during the day and close the curtains, which is more conducive to cooling down.

Second, greening.

If you can plant some plants in your yard, it will not only have high appreciation value, but also make the air fresher, especially some plants such as morning glory and grapes, which will play a role in cooling down.

Third, the fan.

Fans are good at cooling down. Keep a distance when blowing the fan, remember to be too close to the air outlet, and remember that the temperature is too low. If the indoor temperature is really too low, it is suggested that you put cold water in front of the fan, which will make the indoor water evaporate more easily, or wipe it clean with a wet rag before opening it, which will also make the temperature drop faster.

Fourth, the fan.

Fans are inexpensive, and hand-cranked cattail fans can also exercise the elderly.

Five, ice packs

Reusable ice pack is a good tool to reduce skin temperature, and the liquid pre-filled in it can cool down.

Sixth, choose a good pillow

A new type of liquid evaporative cooling pillow can provide a cool night.

Seven, cold water on the wrist

Wash the wrist with tap water for 5 seconds every few hours, because the wrist is where the arteries flow, which can lower the blood temperature.

Eight, massage Tianzhu point

Stick your thumb on Tianzhu point (at the hairline of the lateral edge of the neck muscle), stick your little finger and forefinger near the end of your eyes, then slowly tilt your head, press your thumb with the weight of your head and massage Tianzhu point. It can not only prevent heatstroke, but also improve heatstroke symptoms such as dizziness and tinnitus.

Nine, physical methods

① Wipe your body with a hot towel.

Take a bath with hot water and wash your feet with hot water. Many people think that cold water can cool down. In fact, although taking a bath with cold water can really make you comfortable for a while, you will find that your body will be hotter after a few minutes, because if you take a bath with hot water or wipe your body, you will sweat more, but it will help to open the fine blood vessels in your body and help your body to expel heat, thus cooling down regularly. Although taking a bath with hot water feels a little hot, it will help you cool down.

2 drink hot tea.

Drinking hot tea can stimulate the expansion of capillaries in the human body and obviously lower the body temperature. Don't eat too many cold drinks in summer, because most cold drinks are sweet, which can temporarily relieve the heat, but they don't last, and may even make you hotter after drinking, so this is not a good way to cool down.

How to dissipate heat when it's too hot? 3. How can the room dissipate heat quickly when it is too hot without air conditioning?

Ice water fan

1. Prepare a plastic bottle, add a spoonful of salt and fill it with two thirds of water. The freezing point of brine is lower than that of pure water, and the temperature of iced brine is also lower, which will absorb more heat and have a better cooling effect.

2. Then put the plastic bottle in the refrigerator for refrigeration or freezing. If you want to cool down faster, it is recommended to freeze in the freezer.

3. When the water temperature drops, put a tray in front of the fan and put an iced plastic bottle on it to generate cold air through the melting of ice cubes. Under the blowing of the fan, you can feel the cool breeze blowing head-on, as cool as blowing air conditioning.

Fan with toilet water

There is alcohol in the toilet water, which will make people feel cold after spraying. Turn on the fan and drop a few drops of toilet water on the fan blade. The toilet water will drift around under the drive of the fan blade, which will cool the surrounding air and also have the function of preventing mosquitoes and repelling mosquitoes.

Fan converted into air conditioner

1, prepare three plastic bottles, cut a knife along the plastic bottle body and divide it into two parts.

2, find a piece of hard plastic or cardboard, drill three holes, the size of the round hole is slightly smaller than the bottle body area.

3. Fix the bottle on the round hole with hot melt adhesive.

4. Wrap the hard board in front of the electric fan with the bottle mouth facing outwards.

5, turn on the fan, can produce air conditioning refrigeration effect, the principle is that the wind blows through the bottle mouth, pressure changes, pressure changes will make the air cool, just like blowing on the palm of your hand, blowing with your mouth open, the hot air will come out, and the rising mouth will blow, and the airflow will come out.

Self-made natural variable pressure air conditioner

Using the principle of variable pressure to generate air conditioning, you can also use plastic bottles as natural air conditioning, and you can enjoy cold air without spending a penny. Please don't worry about air conditioning when the room is too hot. The specific method is as follows:

1. Cut the old plastic bottle in half along the bottle body and remove the top of the bottle cap.

2. Find a piece of cardboard and drill a hole in it. The hole is the same size as the bottle mouth.

3. Fix the bottle on the cardboard.

4. Install the whole device on the window, with the bottle mouth facing the room, so that a steady stream of cold air can be blown into the room, which can reduce the temperature regardless of the cost.

How to let the room dissipate heat quickly

1. Mix medical alcohol and clean water according to the ratio of 1: 10, and spray it indoors with a watering can. This can not only reduce the temperature, but also have a certain disinfection and sterilization effect.

There is a kind of heat insulation paper in the market. Sticking to the glass window can effectively block ultraviolet rays and thermal radiation. When it's cool at night, opening the window for ventilation can avoid the sultry heat in the house during the day and dissipate heat quickly.

Hang a wet bath towel at the window. When the water evaporates, the wind blown into the room will be cooler, which can play a role in rapid heat dissipation. You can also mop the floor with a wet mop or directly sprinkle water on the floor to dissipate heat.
