The shocking truth about human heat tolerance

We can stand the heat up to 160 degrees C. Do you believe it?

North and South Vietnam are experiencing extremely opposite weather patterns. While the North continued to sink in the wet, drizzling drizzle, the South people were facing hot heat. High temperatures not only cause discomfort for humans but also cause many kinds of unpredictable diseases. Let's explore the hot weather in a scientific perspective as well as some simple but effective tips to cool the body .

From interesting facts about human heat tolerance .

Not many of us know about our hot tolerance limits . To Saint Petersburg, many people felt suffocated and uncomfortable with the heat of only 24 degrees Celsius.

But in Asian countries, Africa near the equator, the highest temperature in the summer can reach 50 degrees Celsius, yet the people there still live very well. In fact, humans can live well in temperatures above 100 degrees Celsius - the boiling temperature of water.

If I went to Saint Petersburg, many people felt suffocated and uncomfortable with the heat of only 24 degrees C .

To test this possibility, two British physicists had to slip into the toaster oven for a few hours . The results were amazing, they were still "wrinkled" . The conclusion is that in ideal conditions, the environment is dry, people can withstand temperatures as high as 160 degrees C. Why is that?

Humans have 4 heat escape mechanisms : radiation, conduction, convection and sweating . But when it is hot, 3 ways: radiation, conduction, convection will only increase your body temperature . Then, according to experts, the key is to stay in sweat .

. in the African deserts, 50 degrees is still not enough to defeat the people here

We often consider them obnoxious to create body odor but rarely see sweat as a 'natural air conditioner'. When sweat evaporates, they suck in the heat in the air area around the skin, causing this zone to have a temperature lowered below the body's temperature.

In dry conditions, perspiration quickly evaporates or like turning on a fan when sweating will make us feel cooler as well. On the contrary, the higher the humidity, the more hot it is, the more harmful it is to human health.

According to scientists, in conditions of 60 degrees Celsius and very high humidity, after about 10 minutes, all of us will . die. The reason is that when the sweat is unable to evaporate and our body temperature keeps increasing, gradually increasing until it exceeds the tolerance limit.

The question is how to overcome the hot heat with relatively high humidity in a country like Vietnam. Discover and verify the following great science tips:

Firstly, when going to the street, wear loose, cool clothes and absorb sweat well. The color of the clothes should be chosen to be dark red or blue, while helping to avoid heat, preventing harmful UV rays in the sun. This is the result of some scientists' research published in the Industrial & Engineering Chemistry Research magazine.

Second, moderate eating and limiting overeating are also a good way to cool the body. Nutritious foods, especially fat, protein and powdered sugar, stimulate metabolic processes, resulting in more heat released by the body.

That just makes you . more warm in the hot day. Also, you should not use drinks such as beer, wine because they lose water in the body and make you hotter.

Third, you should choose to drink plenty of water (should drink warm water) , eat fruits and especially eat lots of spicy dishes that sweating like chili . This may sound paradoxical but it is completely grounded.

Peppers contain ingredients capsaicin - a substance that feels spicy but does not cause heat in humans. These foods will make your body sweat a lot, which makes us feel cooler. That is the reason that peppers are extremely popular in Mexico, India or Thailand - countries with extremely hot weather.

Fourth, find ways to stay under the ground or the first floor of the house for as long as possible. The reason is that the hot air in the convection flow often moves upward, so the higher the weather, the hotter and hotter the weather, while the weather near the ground will be more comfortable and a little more comfortable.
