To what temperature can a human live, how does the body keep itself cool in scorching heat IG News

Tolerable Temperature: Every year in the summer season, there are reports from various parts of the country that some people have died due to heatstroke or heatwave. The mercury in the country’s capital Delhi rose sharply in February 2023. Then, due to unseasonal rains, the temperature dropped. On Friday i.e. on May 26, Delhi recorded a temperature of 36 degrees Celsius. Have you ever wondered, what is the maximum temperature a human can tolerate and what does the body do to keep cool against the heat?

As most of us know and have experienced, high temperatures are harmful to both our body and health. Sometimes high temperature even proves fatal for some people. However, most people’s bodies tolerate extreme heat and shivering cold. During the summer season, the temperature reaches 50 degrees Celsius in many parts of the country. After all, how does one stay alive in this heat? At what temperature can an emergency situation arise for humans?

How much temperature can be tolerated?

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

According to a report by the London School of Hygiene, heat-related deaths in Britain will increase by 257 percent by 2050. According to scientists, the human body tolerates a maximum temperature of 35 to 37 degrees without any problem. At the same time, when the temperature starts to cross 40 degrees, humans start having trouble. According to studies, maximum temperature of 50 degrees becomes difficult for humans to tolerate. At the same time, higher temperatures pose a threat to life for the common man. According to a report by the medical journal Lancet, India experienced extreme heat outbreaks during the eight years between 2000-04 and 2017-21. Meanwhile, 55 percent increase in deaths due to heat was reported in India.

How to tolerate temperature

The hypothalamus receives energy from dilation of human blood vessels, sweat from the body, breathing through the mouth, going to open places for fresh air. With this energy, the hypothalamus regulates the temperature of the human body. That is why even when the temperature is high, the human being survives by tolerating it. However, in places where the climate is not uniform, temperatures above 45 degrees Celsius are considered dangerous for humans. However, there is no concrete answer yet, what is the maximum temperature at which humans can live? There are different types of atmospheres on our planet, and bodies with different abilities. However, it is better to be careful in high temperatures.

When does heat die?

When talking about the effect of rising temperatures on the human body, doctors and researchers often use the term ‘heat stress’. When our body is overheated, it tries to maintain its core temperature. The extent to which the body tries to maintain its core temperature depends on environmental 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 temperature is 45 degrees. On the other hand, if you stay in temperatures of 48 to 50 degrees or higher for too long, the muscles can completely react and even die.

How the body keeps itself cool

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