Up to what temperature can a human live, how does the body keep itself cool in the scorching heat

Tolerable Temperature: Every year in the summer season, information comes from different parts of the country that some people died due to heatstroke or heatwave. The mercury rose rapidly in February 2023 in the country’s capital Delhi. Then due to unseasonal rains, a drop in temperature was recorded. On Friday i.e. 26 May, a temperature of 36 degree Celsius was recorded in Delhi. Have you ever wondered what is the maximum temperature a human being can tolerate and what does the body do to keep itself cool against the scorching heat?

Most of us know and must have also experienced that high temperature is harmful for both our body and health. Sometimes high temperature also proves fatal for some people. However, most people’s body tolerates the scorching heat and shivering cold. In the summer season, the temperature reaches 50 degree Celsius in many parts of the country. After all, how does a person stay alive in this heat? At what temperature can a crisis situation arise for humans?

how much temperature can be tolerated
According to scientists, the normal temperature of the human body is 98.6 degrees Fahrenheit. This is equal to 37 degree Celsius of the outside temperature. Science says that humans can easily live up to a maximum temperature of 42.3 degree Celsius. According to some studies, humans are warm blooded mammals. Human beings are protected by a special system ‘homeostasis’. Through this process, the human brain is auto-controlled by the hypothalamus to maintain the body temperature within the limits of survival.

The human body tolerates the maximum temperature of 35 to 37 degrees without any problem.

too much heat
According to the report of the London School of Hygiene, there will be a 257 percent increase in deaths due to heat in Britain by 2050. According to scientists, the human body tolerates the maximum temperature of 35 to 37 degrees without any problem. At the same time, when the temperature starts to exceed 40 degrees, then humans start having problems. According to studies, it becomes difficult for humans to tolerate the maximum temperature of 50 degrees. At the same time, a temperature higher than this poses a risk to life for a normal person. According to the report of the medical journal Lancet, there was an outbreak of severe heat in India during 8 years between 2000-04 and 2017-21. During this, a 55 percent increase in the cases of death due to heat was registered in India.

how to tolerate temperature
The hypothalamus gets energy from the expansion of human blood vessels, sweating from the body, breathing through the mouth, going to open places for fresh air. With this energy, the hypothalamus controls the temperature of the human body. That’s why a human remains alive by tolerating it even when the temperature is high. However, in places where the weather is not uniform, the temperature above 45 degree Celsius is considered dangerous for humans. However, so far no concrete answer has been found as to what is the maximum temperature at which humans can survive? There are different types of environments on our earth and bodies with different capabilities. Still it is better to take precaution in high temperature.

when heat kills
Doctors and researchers often use the term ‘heat stress’ while talking about the effect of rising temperature on the human body. When our body is in extreme heat, it tries to maintain its core temperature. The extent to which the body tries to maintain its core temperature depends on the environment and physiological conditions. In this we feel tired. Health experts say that low blood pressure due to complaints like fainting, dizziness or nervousness are common complaints if the mercury is 45 degrees. On the other hand, if you stay for too long in a temperature of 48 to 50 degrees or more, then the muscles can respond completely and death can also occur.

how the body keeps itself cool
According to clinical researches, the body reacts in a special way when the external temperature rises. Actually, more than 70 percent of the body is made of water. In other words, the water present in our body fights the heat to keep the core temperature of the body constant in the rising outside temperature. We sweat in the process. This keeps the body cool. But, if the body goes through this process for a long time, then there is a shortage of water. Some people feel dizzy due to lack of water and some have headache. Some people may even faint. Actually lack of water affects the process of breathing. In such a situation, there is more pressure on the heart and lungs to maintain blood flow. This affects the blood pressure.
