Complete manual of heatstroke prevention
heat stroke
heat stroke is an acute disease in which the central nervous system and the circulatory system are mainly caused by the disorder of the body temperature regulation in the high temperature environment. Besides high temperature and hot sun exposure, working intensity is too large, time is too long, lack of sleep and excessive fatigue are common causes.
according to the severity of clinical manifestations, heat stroke can be classified as threatened heat stroke, mild heat stroke and severe heatstroke, and their relationship is gradual.
symptoms of heatstroke symptom
under high temperature environment, the symptoms of headache, dizziness, thirst, hyperhidrosis, inability to acidification of limbs, concentration of attention, incoordination of movement and so on.
- normal or slightly elevated temperature.
- if transferred to a cool and ventilated place in time, replenish the water and salt, and it will be resumed in a short time.
mild heat stroke symptoms
temperature is usually above 38 degrees.
: dizziness, thirst, and thirst often have a facial flush, a lot of sweating, skin burning and other manifestations, or appear in the limbs of wet cold, pale face, blood pressure drop, pulse increase and other performance.

If not treated in time, they will be critically ill. This kind of heat stroke can be divided into four types: heat convulsion, heat exhaustion, sunstroke and heat stroke.
symptoms of heat spasm: most of them occur in a large number of sweating and thirst, with more water and less salt supplementation, when the concentration of sodium chloride in the blood is sharply reduced. This kind of heat stroke occurs when the muscle suddenly has the spasmodic pain.
symptoms of heat exhaustion: this kind of heat stroke often occurs in the elderly and temporarily unable to adapt to high temperatures. The main symptoms were dizziness, headache, palpitation, thirst, nausea, vomiting, cold skin, blood pressure, syncope or confusion. The body temperature is normal or slightly higher at this time.
symptoms of sunstroke: the heat of this kind of heat is just like its name, because the intense sunlight penetrates the head skin and skull to cause brain cells to cause damage to the head and skull in the sun, and cause the hyperemia and edema of the brain tissue. The discomfort is severe headache, nausea and vomiting, dysphoria, and then coma and convulsion.
symptoms of heat radiation sickness: there are some people who are engaged in physical labor in a high temperature environment for a long time, excessive heat in the body and lack of heat dissipation, resulting in a sharp increase in body temperature. In the early stage of the disease, there are a lot of cold sweat, then no sweat, shallow breathing, pulse speed, restlessness, blur, blood pressure drop, gradually to the coma with the limbs twitching development; serious people can produce brain edema, pulmonary edema, heart failure and so on.
Strategy:
how to do after heatstroke?
when you find yourself and others having symptoms of heatstroke and mild heat stroke, the first thing to do is to quickly evacuate the heat environment that causes heatstroke, choose a cool and ventilated place to rest, and drink some cool drinks containing salt. You can also apply cool oil and air essence in the forehead and temple, or take Chinese medicine such as Ren Dan, Shi Di Shui, Huo Xiang Zheng Qi Shui. If blood pressure falls and collapse, it should be supine immediately. In addition to the immediate transfer of heatstroke from the high temperature environment to the cool and ventilated place, the patients with severe heat stroke should be sent to the hospital quickly, and comprehensive measures should be taken for treatment.
protection:
travel to avoid the sun
summer to go out to remember to prepare sunscreen equipment, it is best not to walk in the sun from 10 to 16 o'clock, because the sunshine is the strongest in this time period, the possibility of heat stroke is 10 times as usual! If you have to go out at this time, be sure to do a good job of protection, such as sunshade, sunshade, sunglasses, and the best use of sunscreen; prepare enough water and drink. In addition, in the hot summer season, drugs for preventing and curing summer temperature, such as drops of water, Rendan and essential oils, must be kept around to prevent emergency use. When you go out, try to use fabrics like cotton, linen and silk. You should wear less chemical fabrics, so that you can not heat up in a large amount of sweat and cause heatstroke.
elderly, pregnant women, people with chronic diseases, especially those with cardiovascular diseases, should reduce their activities as much as possible during the hot season.
don't wait for thirst to drink water
don't wait for thirst before drinking water, because thirst has already indicated that the body is short of water. The best thing is to drink 1.5 to 2 litres of water a day according to the temperature. When sweating is more, we can add some saltwater to make up for the salt lost by human sweat. In addition, in summer, the body is prone to potassium deficiency, which makes people feel tired and tired. Potassium containing tea is an excellent summer refreshing drink. The water content of vegetables such as lettuce, cucumber and tomato in summer is high, and the water content of fresh fruit, such as peach, apricot, watermelon and melon, can be used to supplement water from 80 to 90%. In addition, dairy products can replenish water and meet the nutritional needs of the body.
keep enough sleep
short summer day, high temperature, strong metabolism and high consumption, easy to feel tired. Adequate sleep can relax the brain and body system, which is conducive to work and study as well as measures to prevent heatstroke. The best bedtime is from 22 to 23. The best time to get up is 5:30 to 6:30. When sleeping, be careful not to lie under the outlet and fan of the air conditioner, so as not to suffer from air conditioning diseases and hot colds.
