Hot Weather In Summer Is Easy To Cause Heat Stroke. How To Prevent Danger?

- Jul 18, 2018-

Heatstroke is an acute disease characterized by central nervous system and circulatory system disorders caused by heat and heat absorption in the human body in the high temperature and high humidity environment. Heat stroke can make people feel headache, dizziness, thirst, and then the body temperature rises rapidly, and even coma.

The main causes of heat stroke are the following:

1. Is the outside temperature too high?

When the outside temperature is too high, it is easy for the body temperature to rise. This can easily happen, for example, when exposed to the sun or working in a hot workshop. At this time, the temperature of the body is greatly increased, and beyond the level that the human body can tolerate, it will cause heat stroke. This condition is also called heatstroke. ??

2. Is the ambient humidity high?

One of the main ways to dissipate heat is sweating. If the surrounding air is not dry enough, the sweat from the body cannot be turned into steam, and it is impossible to take away excess heat from the body. Heat stroke caused by this cause often occurs in high temperature workshops. 

3. Is the sodium salt lost?

Sodium salt is an indispensable substance in our body. When the body sweats, it will discharge sodium salt. If it is not replenished in time, it will cause muscle spasm. This is what we often call cramps, which are called heatstroke in medicine. 

4. Is the air flow poor?

In addition to the close relationship with the humidity and temperature of the surrounding environment, the flow of the surrounding air has a great relationship with heatstroke. If the air flows fast, it can accelerate the evaporation of sweat, the skin feels cool, and the body does not accumulate too much heat. If the heat dissipation of the skin is affected, the body temperature of the person will increase step by step, resulting in symptoms of heat stroke.

How to deal with the emergency:


The enthusiasm usually occurs after strenuous exercise and a lot of sweating, when the salt and water in the human body are lost along with the sweat. In addition, enthusiasm may also be a manifestation of heat exhaustion. 

How to identify: enthusiasm for muscle pain or convulsions. Usually occurs in the abdomen, arms or legs after strenuous activity. Often symmetrical, sometimes seizures, sometimes relieved. The patient is conscious and his body temperature is generally normal. 

What to do: If the situation is not serious enough to seek medical attention, stop all activities, sit in a cool place to rest, drink diluted, refreshing juice or sports drinks. If the patient has a history of heart disease, a low-salt diet, or if the enthusiasm does not resolve after 1 hour, seek professional medical treatment. ?

2.Heat exhaustion

Heat exhaustion is a disease in which high blood temperature or strong heat radiation causes peripheral blood vessels to dilate and a large amount of water loss, resulting in a decrease in circulating blood volume, causing vaginal discharge due to insufficient intracranial blood supply. Older people, hypertensive patients, people who perform heavy physical activity such as heavy physical labor or long-distance running in high-temperature environments are more prone to heat exhaustion.

How to identify: Heat exhaustion is rapid, and its symptoms include dizziness, headache, nausea or vomiting, excessive sweating, fainting and so on. People with heat exhaustion may be cold and damp. The patient's blood pressure drops, the pulse is fast and weak, and the body temperature is slightly higher or normal. At this time, if the patient has stomach, diarrhea or vomiting, it will lose more body fluids and the situation will continue to deteriorate, and even cause a fever. 

What to do: Drink a cool, non-alcoholic beverage, rest immediately, take a cool shower or wipe your body if possible, and turn on the air conditioner and replace it with loose clothing.

3.Heat sickness

When the body is unable to regulate its body temperature, a heat shot can occur. High temperatures cause the body temperature to regulate central dysfunction, causing the body temperature to rise rapidly. The body temperature can reach 40 degrees Celsius or more within 10 minutes to 15 minutes. If you do not receive an emergency ambulance, a fever can cause death or disability. 

How to identify: The performance of heat-induced diseases is diverse, mainly dizziness, nausea, high body temperature, blurred consciousness, and unclear articulation. ?

How to deal with it: If the patient has the above symptoms, he should promptly notify the emergency center and wait for the rescue. Move the patient to the cool and ventilated place to rest on his back. If conditions permit, scrub the patient with ice water or alcohol to help cool down. When the patient's muscles are involuntarily twitching, prevent the patient from harming himself. Don't put anything in the patient's mouth. If the patient has vomiting, flip the body to lie on his side to ensure that the breath is smooth. How do different people prevent heat stroke? ?

4.Pregnant women, children

Pregnant women and children are high-risk people in summer heatstroke, need to pay attention to ventilation and enhance physical fitness. Experts suggest that the rooms of pregnant women and children should pay attention to ventilation, and the clothing should not be too much in the summer, mainly for comfort, and the bedding should not be too thick. The electric fan, air conditioner, etc. can be used to adjust the indoor temperature to avoid convective wind. Drink more water and eat more fresh fruits. If you have fever, you should seek medical attention as soon as possible, and do not force sweating. Usually strengthen exercise, enhance physical fitness, to reduce the possibility of heat stroke. ?

5.High temperature operators

Most of the high temperature workers are young and middle-aged. Most of these people are construction workers and sanitation workers. High-temperature work is not suitable for everyone, and people who need good health and good physical strength can afford it. Therefore, before choosing high-temperature outdoor work, you must first assess whether you are “eaten”. 

People with high blood pressure, diabetes, tuberculosis, central nervous system diseases, and older, poorer people are not suitable for high temperature work.
