If a person were to work outdoors, what would happen to his body?
How long can he last in 40 degrees Celsius?
If he's lucky, he'll be able to hold out for a few hours, and if he's unlucky, he'll die of heat in a while.
What if this happens?
What if there is no emergency ambulance on site?
Changes that occur in a person in a high-temperature environment.
From the perspective of human physiology, the human body maintains body temperature through metabolism, so what changes will occur when people are under the ring of high temperature?
Changes in the environment of people in high temperatures.
The normal body temperature of a person is determined by whether the process of metabolism is normal, so when a person is in a high temperature environment, the body will speed up the metabolism.
In the process of metabolism, a lot of heat is produced, and in order to lower the body temperature, the person sweats.
Sweating can lead to water loss in the body, and if not replenished in time, it can lead to dehydration, which is a dangerous sign of occurrence.
However, dehydration can be maintained by replenishing water in time to maintain a normal physical state, and when dehydration becomes more and more severe, it will cause heat stroke.
Of course, heat stroke is not only caused by dehydration, but also by high body temperature.
There are three types of heat stroke, namely heat cramps, heat stroke and heat stroke, and the severity of this is progressively worse.
The symptoms of heat cramps are shortness of breath, a weak, rapid pulse, accompanied by dry skin.
Symptoms of heat stroke are irritability, migraine and nausea.
Heat stroke, on the other hand, can cause severe dehydration, accompanied by mental trance, and even coma.
Hyperthermia can cause complications, with a gradual weakening of consciousness and even coma.
In a comatose state, it is dangerous for one's life.
In addition to this, hyperthermia can also cause a variety of diseases.
How to take care of yourself.
When people reach the summer, they will begin to pay attention to heatstroke prevention and cooling, and carry out corresponding maintenance for themselves, and the same is true for children.
So how to prevent heatstroke and cool down for yourself?
1. Replenish water.
Because the number of sweats in summer is more, the daily water loss will be relatively fast, and at this time, it is necessary to properly replenish water indoors.
Usually drink six or seven glasses of water a day, but when the body's metabolism accelerates, it needs to be replenished with more water, otherwise it will lead to dehydration.
In addition, it is necessary to bring some water when going out, otherwise some people will break out in a cold sweat when they are nervous, and at this time you can wash it with water, which will make people feel cool and not so nervous.
2. Cool indoor air-conditioned environment.
When the outside temperature is high, it is still recommended to go out as little as possible, and indoor ventilation is also a good choice, but without air conditioning, air conditioning is the coolest to turn on, so it is important to stay in the room as much as possible and keep it cool.
3. Eat less spicy food.
When the body's metabolism accelerates, the appetite will be better, but for people with a good appetite, they must also pay attention to the food they eat, otherwise it will lead to physical discomfort.
Eat less spicy food in summer, pepper, pepper, cumin and other foods will affect the normal work of the digestive system and cause people to feel unwell.
4. Pay attention to safety when sleeping.
Some families may turn on the air conditioner until night, but the night is also the time for the body to recover energy, so many people will wake up in the morning and feel that their brains are not awake.
In this case, it means that the air conditioner is turned on to a very low temperature, so remember to turn down the temperature of the air conditioner before going to bed to ensure the quality of your sleep.
epilogue
Although the body structure of people is basically the same from person to person, everyone's tolerance is different.
Some people will suffer from heat stroke due to hyperthermia caused by excessive metabolism, but some people can persist for a long time with their own endurance, but we still have to be vigilant and not to have such a situation.
