British climatologist Tom middot; Matthews published an article on the 25th saying that the human body is' approaching the caloric limit '. When the wet bulb temperature reaches 35 ℃, the human body will lose the ability to adjust its own temperature and can only survive for a few hours. Morgan Stanley released a report that the number of people at risk of infectious diseases will increase by 1 billion in the next 50 years.
What happens if you lose the ability to regulate your temperature
Only a few hours
Human body limit
Human limit refers to the physiological limit that the body can withstand under various extreme environmental pressures. The infinite potential of the body is still being studied and developed.
Minimum body temperature limit
People's core temperature is 37 degrees Celsius. Generally speaking, the external temperature is about 20 degrees Celsius, which can cause hypothermia. Once the body temperature drops to 36 degrees Celsius, people's reaction and judgment will be weakened; It's difficult to walk when it's down to 35 degrees; When it drops to 33 degrees, people will lose their reason; At 30 degrees, people lose consciousness. When the core temperature reaches 24 degrees Celsius, the heartbeat stops. However, the world's lowest known temperature record is 13.7 degrees Celsius.
Maximum body temperature limit
This is also a result proved by examples. In 1980, the temperature in Atlanta, Georgia, USA was 32.2 ℃, and Willy & middot, 52; Jones was admitted to Grady Memorial Hospital in Atlanta because of heatstroke. At that time, his temperature reached a record of 46.5 ℃, and it was 24 days before he completely subsided.
It is suggested that the upper limit of axillary temperature in normal people is usually 37.4 ℃. If it is hot, the maximum temperature can not reach 42 ℃.
Ambient temperature limit
Ambient temperature limit: about 116 ℃
Answer: This is the temperature at which the human body can still breathe.
Scientists have experimented with the highest temperature that the human body can endure in a dry air environment: the human body can last for a whole hour at 71 ℃; At 82 ℃, it can last for 49 minutes; At 93 ℃, it can last for 33 minutes; At 104 ℃, it can last only 26 minutes. However, according to relevant literature, the limit temperature that the human body can tolerate seems to be higher.
Tip: relevant experiments have found that due to the inability to evaporate heat through perspiration, people's ability to withstand high temperature in water is significantly lower than that in dry air.
