The latest research shows that 5 billion people will be exposed to dangerous high temperature in 2 100. This weather is very dangerous. First of all, hot weather can cause convulsions and fatigue. Secondly, hot weather can also lead to death from heatstroke. ?

The latest research results show that high temperature can kill people, and the best way to avoid the influence of extreme high temperature is to stop gas emission. By 20 1 1, the global average temperature will rise by 2. 1℃ to 4.3℃, and the high temperature index will reach 5 1℃. By that time, places like India and sub-Saharan Africa may be exposed to dangerous high temperatures for a long time every year. Overall, more than 5 billion people may be exposed to dangerous high temperature and humidity most of the time. When people are completely exposed to this weather, it is actually very dangerous.

First of all, hot weather can cause convulsions and fatigue. In high temperature weather, if people's body continuously evaporates water and can't replenish sugar water and salt water in time, then the water and salt in the body will be out of balance, which will cause dehydration. After dehydration, people's bodies can easily cause convulsions. Moreover, under extreme high temperature, if you keep this state of sweating, thirst and rising body temperature for a long time, people will have symptoms of chest tightness and asthma, and feel tired and tired.

Secondly, hot weather can also lead to death from heatstroke. Many people suffer from heatstroke in hot weather, which is well known, mainly because the temperature regulation system of the human body is disordered and cannot maintain the heat balance of the body. If there is a problem with body heat dissipation, excessive heat storage and excessive sweating, it will lead to disorder of body temperature regulation, resulting in symptoms of heatstroke. Some people will suffer from heat exhaustion and severe fainting due to extreme high temperature, especially some vulnerable people, such as children and the elderly, who may have some chronic diseases and die easily in such an environment.

In a word, it is still very dangerous in extremely hot weather.
