What temperature is it possible to get heat stroke, and how many degrees are people prone to heat st

If the human body is not able to sweat properly, it will cause heat stroke.

Heat stroke is a symptom characterized by heavy physical labor, imbalance of water and electrolytes, and dysfunction of cardiovascular and central nervous system in an environment with high temperature and high humidity. The condition is related to the health status and adaptability of the individual.

The external factors for heat stroke are mainly high temperature, high humidity and low wind speed.

It is easy to occur in high-temperature radiation working environment (dry heat environment) and high temperature and high humidity working environment (damp heat environment). According to research, the average temperature for three consecutive days exceeds 30 degrees Celsius and the relative humidity is greater than 73%, and heat stroke is most likely to occur.

At the same time, it should also be noted that although the temperature is not high and the humidity is not high, due to poor environmental ventilation, heat stroke is also prone to occur, such as in summer, people are prone to heat stroke in a closed working environment.

In the city, all kinds of tall buildings affect air circulation, the large-scale use of air conditioning in summer, the narrowness of the streets and the gradual increase of vehicles, the use of various instruments and equipment, the reduction of urban green area, etc., form a heat island effect, increase the temperature of the city. As well as the increase in global carbon dioxide emissions, the greenhouse effect, and the trend of rising temperatures, all of which have led to an increase in heat stroke.

Generally, heat stroke is more likely in the following two situations: one is high temperature and high radiation, which is commonly known as dry heat. Strong sun exposure and high temperature can easily lead to a large loss of water in the human body, and if the water is not replenished in time, it is very easy to suffer from heat stroke; The other is high temperature and high humidity, which is a common hot and humid day in summer, the human body can not sweat normally, and the increase in blood flow will also lead to heat stroke.

How do I know if I'm suffering from heat stroke?

Heat stroke can generally be divided into three categories, namely premonitory heat stroke, mild heat stroke, and severe heat stroke, with the following symptoms:

Patients with premonitory heat stroke are manifested by symptoms such as profuse sweating, dizziness, chest tightness, nausea, and weakness of limbs. Normal body temperature or slightly elevated, if you can leave the high fever environment in time, the symptoms can disappear after a short period of rest;

Patients with mild heat stroke have symptoms of premonitory heat stroke, accompanied by vomiting, clammy cold, and blood pressure drops. After mild heat stroke**, it can generally return to normal after four or five hours;

Most cases of severe heat stroke are sudden coma in a hot environment. Symptoms such as headache, numbness and tingling, dizziness, burning and crimson, and body temperature often above 40 are common.

If the landlord is satisfied, it is a satisfactory answer. Thank you.

Long-term exposure to high temperatures, exposure to the sun, etc., can cause heat stroke.

If the temperature is above 30 degrees Celsius and the humidity reaches 73% or more, it is particularly prone to heat stroke.

Professor Zhang Da of the Emergency Department of Beijing Chaoyang Hospital explained that colds are generally upper respiratory tract infections caused by colds, while heat stroke is generally caused by high temperature and high humidity. If the temperature is above 30 degrees Celsius and the humidity reaches 73% or more, it is particularly prone to heat stroke. Zhang Da reminded.

Zhang Da said that heat stroke is likely to occur 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.

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. When engaging in heavy physical labor in summer, or when the body is unwell and causes fever and uses some drugs, 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;

Third, heat dissipation obstacles. When the air humidity is too high, the body temperature cannot be lowered by sweating, and the heat will be retained in the body. Excessive obesity and poor air penetration of clothing can also cause heat dissipation obstacles.

40 degrees. Rest places shall meet the following conditions:

1) It is located in the work area or not far from the work site, and is isolated from the influence of high temperature and thermal radiation;

2) Equipped with basic heatstroke prevention and cooling facilities such as pergolas, seats, fans, etc., and prepared with cool drinks and commonly used heatstroke prevention medicines; Air conditioning, spray fans and shower facilities can be added;

c) Well-ventilated silver friends.

Measures for Labor Protection in Chongqing for High Temperature Weather

Article 23 Where an employer violates the provisions of these Measures by committing any of the following acts, and causes serious damage to the health of the worker or is extremely corrupt, the employer and its responsible person shall be investigated for corresponding responsibilities in accordance with the relevant provisions; where a crime is constituted, criminal responsibility is pursued in accordance with law

1) Arrange for workers to work for more than 6 hours in moderately high temperature weather or fail to suspend work during high temperature hours from 12 o'clock to 16 o'clock in accordance with the provisions of these Measures; Due to the requirements of the production process, the work during the high temperature period cannot be suspended, and the open air work during the high temperature period is not suspended in accordance with the provisions of these measures; Due to the requirements of the production process, it is necessary to work in the open air during the high temperature period, and the work and rest time is not reasonably adjusted in accordance with the provisions of these measures;

2) Cooling measures taken in high-temperature weather cannot reduce the temperature of the workplace to the standards specified in these measures, and the work is not stopped in accordance with the provisions of these measures; Due to the requirements of the production process, the work cannot be stopped, and the work during the high temperature period from 12 o'clock to 16 o'clock is not suspended in accordance with the provisions of these measures.

Biology defines 42 degrees as a lethal temperature. In other words, if you work in a 42-degree environment for a long time, you will suffer from heat stroke and may die.
