What is the maximum degree of heat that humans can tolerate?
There is a huge fire around the world. Temperatures hit record highs in most countries. The United Nations says that the world is now in a boiling period, beyond the warming period. In such a situation, people are gasping. How much temperature might the human body at any point endure?
BBC radio presenter James
Gallagher took part in a study to test how much heat the human body could
withstand. He highlighted the experience of participating in this study led by
Professor Damien Bailey of the University of South Wales in a BBC report.
Professor Bailey took him to
an environmental chamber. It is a waterproof scientific system in the form of a
simple chamber to control temperature, humidity and oxygen levels.
At 21 degrees Celsius, the
temperature seems just right. Then Professor Bailey gave the first instructions
for "removing everything from the body". It will show how much James
sweats and how his weight changes.

Several experiments were performed with a
pause in temperature rise at 35 °C. James felt the warmth then. While sitting in
a chair is not uncomfortable, one would not want to work or exercise in this
temperature.
Some obvious changes can be
noticed in James' body. He looked rather red. Because the blood vessels on the
surface of his skin were opened to release the warm blood temperature into the
air.
James was sweating but not
sweating. This sweat was evaporating and giving him chills again. The temperature
was then raised to 40.3 °C. "I felt the force crush me all over," James
said.
Professor Bailey said: “5 degrees Celsius
seems very low. But physically it is quite difficult.
Bailey said the human body can work up to 37
degrees. At 40 degrees, our consciousness fades and the fear of fainting
increases. Body tissues are damaged by high core temperatures. Like heart
muscle and brain.
He said, "When the middle
temperature showed up at 41-42 degrees Celsius, we saw a troublesome issue. If
someone doesn't get emergency treatment, they can die from hyperthermia.
Some general tips for dealing with these high
temperatures are staying in the shade, wearing loose clothing, avoiding
alcohol, keeping your home cool, and avoiding exercise during the hottest part
of the day. Day of the match and drink plenty of water.
