In many countries around the world, including Pakistan, millions of people are currently experiencing higher than normal temperatures due to extreme heat and heat waves._x000D_
_x000D_
In fact, the intensity and duration of heat waves have increased significantly as a result of climate change._x000D_
_x000D_
This is why a question that many people ask is how much temperature can be considered too much for daily activities._x000D_
_x000D_
The answer to this question is not simple because along with temperature, the amount of humidity in the air also plays a role in this regard. A 2010 study reported that 35 degrees Celsius is the ultimate limit of protection for the human body in a high-humidity area._x000D_
_x000D_
At temperatures higher than this, the human body is unable to cool itself by evaporating sweat and the body temperature increases, which increases the risk of heat stroke._x000D_
_x000D_
But in recent years, global temperatures have increased significantly and the tolerance of the human body has also been affected._x000D_
_x000D_
This is why scientists are doing a lot of research on this. In 2023, a study by the University of Roehampton in the UK found that at a temperature of 40 degrees, the human body has difficulty controlling heat and has to struggle hard to keep itself cool._x000D_
_x000D_
In this study, 13 adults were made to rest for an hour in an environment with different temperatures and humidity._x000D_
_x000D_
During the study, experiments were conducted at temperatures ranging from 27 to 50 degrees Celsius._x000D_
_x000D_
The study found that when the temperature reaches 40 degrees Celsius, the metabolic rate increases, especially if the humidity in the air is very high. According to the researchers, the results indicate that at temperatures of 40 to 50 degrees Celsius, the human body has to struggle a lot to keep itself cool._x000D_
_x000D_
The study found that not only high temperatures are dangerous to human health, but high humidity, along with heat, also proves to be more dangerous for the body._x000D_
_x000D_
In a study conducted by Pennsylvania State University in the US in July 2023, it was reported that due to the combination of high humidity (more than 50%) and temperature, the human body fails to cool itself at 31 degrees Celsius instead of 35. Difference between dry and humid environments_x000D_
The American study showed that in dry and hot weather, our body is able to cool itself by evaporating sweat, but humans can only sweat to a certain extent, after which the body starts accumulating more heat._x000D_
_x000D_
But in such weather, the body performs daily tasks with caution and comfort even at 40 degrees Celsius._x000D_
_x000D_
In comparison, if the temperature is lower but the humidity is high, it increases the pressure on the heart and other bodily systems._x000D_
_x000D_
In such weather, when the temperature is above 30 degrees Celsius, it becomes difficult for the body to control its temperature._x000D_
_x000D_
Researchers will now conduct research on older people because aging reduces the human body’s ability to tolerate heat.
