What is the temperature cut off for death from heat stroke?

The threshold for death from heat stroke is about 41,42 degrees.

The detailed reasons are as follows:

As we all know, a person's body temperature is maintained at around 37, while ** is under normal circumstances.

33℃。The difference between these 4 allows the heat generated in the metabolic process in the body to be transferred to the body, and then the heat is transferred to the outside of the body through radiation, evaporation and air convection, so as to ensure that the body temperature is basically constant. Therefore, the ambient temperature should be below 33 for the human body to feel comfortable.

From the perspective of people's response to high temperatures, a temperature of about 30 is the temperature that the human body feels best, because at this temperature, the human body generally does not need to "work" sweat glands to dissipate heat, nor does it need to wear clothes to keep warm. In the case of clothing (referring to single clothing), the temperature is between 19 and 24 o'clock, and people feel moderately hot and cold, refreshing and comfortable. If the temperature exceeds 33, the body will feel hot, and this is when the body's sweat glands begin to "kick in" and dissipate the accumulated heat in the body by sweating slightly.

When the temperature reaches 35, the blood vessels of ** begin to expand, the heartbeat begins to accelerate, and the blood circulation also accelerates, resulting in the blood flow of ** increasing several times to increase the heat dissipation on the body surface. At this time, the room air conditioner must be activated, or other cooling measures must be taken. When the temperature reaches 35 or above, the amount of blood pumped by the heart increases by 50 to 70.

Therefore, it is not difficult to understand the reason why 35 is regarded as a warning temperature for high temperatures and heat stroke. When the temperature exceeds 38, multiple organs of the person participate in the cooling. When the temperature reaches 39, the sweat glands are already quite tired and tend to fail, and it is easy to have a sudden heart attack.

If the temperature rises above 40 in a summer heat wave, the high temperature will make people dizzy and unsteady on standing, and if the person's body temperature cannot drop to normal body temperature, it will not only damage the heart, but also cause permanent damage to the brain due to the overheating of the brain intracranial tissues, resulting in meningeal and cerebral congestion, hemorrhage and edema.

Therefore, the critical line of body temperature for death from heat stroke should be around 41,42 degrees.

A body temperature of more than 42 degrees Celsius can lead to death.

Heat stroke to death is a relatively long process, and no one dies as soon as they suffer from heat stroke. If heat stroke is properly handled, it will generally not die, unless the body is not good and complicated by other diseases. If heat stroke is not dealt with for a long time, no matter how good a person is, he will die.

It has nothing to do with temperature, and it is easy to suffer from heat stroke when working in a high-temperature, high-humidity, and unventilated environment. For example, sanitation workers, construction workers, or people in food and beverage establishments who work in closed environments are prone to heat stroke. In addition, the carriage is also a high-temperature, high-humidity, unventilated environment, and it is also prone to heat stroke.

A cold is usually an upper respiratory tract infection caused by a cold, while heat stroke is generally caused by a high temperature and high humidity environment. In Western medicine, the cold is considered to be a respiratory infection caused by pathogens such as bacteria or viruses that invade the body, and it is an infectious disease. Heat stroke is a physical and chemical disease and is a non-infectious disease.

1. Premonitory heat stroke.

In a high temperature environment, heat stroke patients have dizziness, dizziness, tinnitus, nausea, chest tightness, palpitations, weakness, thirst, sweating, lack of concentration, numbness in the limbs, at this time the body temperature is normal or slightly high, generally not exceeded. This is a precursor to heat stroke, and if timely measures are taken such as leaving the scene of the heat quickly, it can prevent the development of heat stroke.

2. Mild heat stroke.

In addition to the manifestations of premonitory heat stroke, there are also early manifestations of respiratory and circulatory failure such as flushing or paleness, nausea, vomiting, shortness of breath, sweating, hot or clammy cold, weak pulse, rapid heart rate, and decreased blood pressure.

3. Severe heat stroke.

In addition to the manifestations of premonitory heat stroke and mild heat stroke, it is accompanied by fainting, coma, convulsions or high fever.

4. Severe heat stroke can continue to be divided into:

Heat stroke and high fever, which is a large amount of heat accumulation in the body. People with heat stroke may experience drowsiness, coma, flushing, dry heat, no sweating, shortness of breath, increased heart rate, decreased blood pressure, high fever, and body temperature can exceed 40 degrees.

Heat exhaustion, i.e. the absence of a large amount of heat in the body. People with heat stroke may appear pale, clammy and cold, weak pulse, shallow and fast breathing, syncope, coma, and decreased blood pressure.

Heat stroke can be divided into three types according to the severity, precursor heat stroke, mild heat stroke and severe heat stroke.

Premonitory heat stroke: Symptoms such as thirst, fatigue, sweating, dizziness, dizziness, tinnitus, headache, nausea, chest tightness, and difficulty concentrating.

Heat stroke symptoms: The symptoms before the precursor heat stroke are aggravated, with nausea and vomiting, pale or flushed, sweating, dehydration, etc.

Severe heat stroke: high fever, convulsions, convulsions, shock, coma and other symptoms.

Analysis: Huang Yan, director of the emergency department of the Fourth Hospital of Changsha, said that the public needs to prevent severe heat stroke. If shock is caused by severe heat stroke, it can aggravate the damage and failure of human organ function.

Severe heat stroke can reach 41 degrees Celsius.

If you are hot or cold, you will be prone to heat stroke.

For example, if you are in an air-conditioned room with 26 degrees or lower, go out to 32 degrees or more, and the temperature difference between inside and outside is more than 6 degrees, and then return indoors, the temperature changes too quickly, and you are prone to heat stroke.

Or in the heat for a long time, and there is no protection!

Heat stroke is composed of a variety of factors, such as ambient temperature, relative humidity, and depending on the person's own situation, for example: in a closed environment, the humidity exceeds 40 percent, and the temperature exceeds 30 degrees.

If the air is flowing at a high temperature of 36 degrees, the human body can replenish water normally, and generally will not suffer from heat stroke!

The general air humidity in the air conditioner room is relatively small, which can ensure that the human body is not short of water, and it is generally recognized that there will be no heat stroke if it does not exceed 30 degrees!

With a high temperature of 30 degrees Celsius or more and a humidity of 73% or more, heat stroke is particularly susceptible.

Heat stroke is a common disease in summer, and its onset is extremely rapid and can cause damage to people instantly. The main causes of heat stroke are:

First, the ambient temperature is too high. A high-temperature and humid environment, or a blazing direct sunlight, can cause a person's body temperature to rise rapidly. Heat stroke occurs when the temperature exceeds body temperature and the relative humidity exceeds 85%;

Second, there is an increase in heat production. In the summer, when you engage in heavy physical work, or when you have a fever or use certain drugs due to physical discomfort, the body's own metabolism will be accelerated, causing the body temperature to rise. In addition, hyperthyroidism can also cause an increase in body temperature;

Heat stroke can occur above 30 degrees Celsius, especially if the relative humidity of the air is not reached, and the chance of heat stroke is high. If the relative humidity is too low and the temperature is high, there is a high risk of heat stroke if you are exposed to the sun all the time. Chest tightness, profuse sweating, and in severe cases, some fainting may occur.
