About "heat stroke", this knowledge you should know earlier...

This year's "Grilling Mode" has officially opened! In persistently hot weather, heat stroke is very easy to occur. Heat stroke may seem like a minor problem, but it can be handled improperly and can lead to serious consequences. Therefore, you must know this knowledge earlier...

Who is more likely to suffer from heat stroke?

Humans are thermostatic animals, and the maintenance of body temperature benefits from the "intelligent" regulation of the human body's thermogenic and heat dissipation systems. When people stay in a high temperature environment for a long time, when the body's "intelligent" regulatory system "strikes", it will lead to damage to the function of organs such as the central nervous system and cardiovascular system, which is heat stroke.

Heat stroke can not only occur in high temperature environments, but also in environments with poor heat dissipation conditions, such as confinement to cover the quilt custom, cold cover quilt heat, work in protective clothing, stay in a poorly ventilated environment for a long time to engage in heavy physical labor can also occur heat stroke.

In addition, excessive work intensity, excessive time, lack of sleep, excessive fatigue; old age, maternal, frailty, malnutrition, obesity, hunger, heavy drinking, wearing tights and impermeable clothes and pants; hyperthyroidism, diabetes, cardiovascular and other chronic diseases, impaired sweating function (scleroderma, congenital sweat gland deficiency, scarring after extensive burns), taking drugs that affect body temperature regulation (anticholinergic drugs, antihistamines, antipsychotics, β receptor blockers, diuretics) and other people are more likely to develop heat stroke. These people should be more vigilant about the occurrence of heat stroke!

How to identify heat stroke?

Heat stroke has a process of occurrence and development, we should identify it as soon as possible, beware of the occurrence of severe heat stroke. Severe heat stroke includes heat cramps, heat exhaustion and heat stroke, and if you really get to the point of heat stroke, you are struggling on the death line!

Aura heat stroke: stay in a high temperature environment for a long time, thirst, limb weakness, sweating, dizziness, lack of concentration, etc., at this time the body temperature can be normal or high, generally not more than 38 ° C.

Mild heat stroke: In addition to the above manifestations, there are also red or pale faces, sweating, nausea, vomiting, palpitations and other manifestations, and the body temperature often exceeds 38 ° C.

Severe heat stroke: In addition to the above manifestations, there can also be "cramps", fainting, coma and other manifestations, and the body temperature can exceed 40 ° C.

What should I do if I have heat stroke?

Once we find signs of heat stroke, we should deal with it immediately and nip it in the bud, don't carry it hard!

1, where cool and where to stay

Immediately leave the hot environment, "where cool and where to stay", such as a fan or air conditioning place. Don't take a break to continue to go out, which will only further overdraft the energy and aggravate heat stroke.

2. Drink water

Drink light salt water or sports drinks in small amounts and times to replenish lost water in your body. Do not drink drinks that contain ethanol or are rich in sugar, which can cause the body to lose more body fluids. In addition, drinking too cold frozen drinks should also be avoided to avoid stomach cramps and cause stomach discomfort.

3. Cool down

Try to take off your clothes, which is conducive to the rapid dissipation of heat in your body; after taking off your clothes, sprinkle some cool water on your body to help dissipate heat. If possible, blow the air with a fan or electric fan, wipe the body with a wet and cool towel, rinse the whole body with water under the tap, or soak in a bathtub filled with cool water. It would be nice if there were ice packs or frozen drink bottles around. Ice packs or frozen beverage bottles can be wrapped in clothes or towels, placed on the forehead, the back of the head, the sides of the neck, the armpits on both sides, the base of the thighs, etc., so that the blood in these areas can be quickly cooled.

In addition, it should be emphasized that many people equate heat stroke with a cold and treat heat stroke with antipyretic drugs. In fact, the common cold is an upper respiratory tract infection caused by rhinovirus, coronavirus, etc., while heat stroke is the body's "too hot" due to impaired body temperature regulation. Therefore, the treatment of heat stroke is to make people "cool", rather than eating anti-fever drugs, eating anti-fever drugs will cause patients to sweat further, aggravate the loss of water electrolytes, and aggravate the disease.

The above is the treatment method of heat stroke with mild symptoms, once severe heat stroke occurs or does not get better after treatment by the above method, you should call the 120 emergency number in time.

How can I prevent heat stroke?

Indoors, try to keep cool and comfortable, if you turn on the air conditioner or fan, it is recommended that the air conditioning temperature be adjusted to about 26 ° C, too low will make people from indoor to outdoor when the temperature difference is too large, causing a burden on the body.

Outdoors, of course, it is best to avoid going out during the high noon heat. If you go out, you should take sun protection measures, bring a parasol, wear a sunhat, sunglasses, try to wear light, loose and light clothes, apply sunscreen, bring enough cool water with you, and move in a cool place.

In hot weather, everyone should drink more water. If you are doing manual labor or strenuous exercise in a hot environment, drink at least 2 to 4 glasses of cold water (500 to 1000 ml) per hour. It is best not to wait until you are thirsty to drink water, and you should drink a small amount of water several times according to your own schedule.

In addition, in the hot summer, anti-heat cooling drugs must be prepared around, such as wind oil essence, Huoxiang zhengqi water, etc., in case of emergency use. When going out, you should wear loose and breathable light-colored clothing, and appropriately supplement heat-proof drinks. For example, 1. soaking water: honeysuckle, chrysanthemum, monk fruit, goji berries; 2. various teas: lotus heart tea, lotus leaf tea, mint tea; 3. eat more melons in summer high temperature, eat more melons.

Finally, it's important to stress that never leave infants or children in a parked car. Even if there is a gap in the window, don't do it.

Say a thousand ways and ten thousand: heat stroke is not a trivial matter, it can really be fatal, cool is the key, necessary 120!
