The heat each year is becoming an increasing problem for the whole world. The human body suffered, but it could not withstand hot weather could not be overcome. So what is the temperature – the most acceptable for our body? The livescience.com gate has found a question.
According to the results of the scientific work, since 2020, published in the journal Science Advances, everything is quite simple – a person who can withstand temperatures up to +35 degrees Celsius, according to damp thermometer. But the emphasis here is exactly at the end, because the temperature in the wet thermometer is not the same described in the weather forecast.
A similar temperature measured by a thermometer is covered in a damp cloth, so freezing is taking into account both heat and humidity, which is very important. The more water in the air, the more difficult it is to evaporate the sweat from the human body and cool the body.
At low humidity, but high temperatures, and vice versa, the temperature in the moist thermometer probably does not come close to the maximum for humans. But if both parameters are high, this index may be dangerous for health.
For example, at the air temperature at +46.1 degrees Celsius, humidity 30%, the temperature in the wet thermometer will be only +30.5 degrees. But when the air warms up +38.9 at 77%humidity, the wet thermometer will show about +35 degrees – a dangerous number for the body.
The reason why heat and high humidity is very dangerous is simple – a person who loses his ability to adjust the internal temperature. If the temperature through the wet thermometer exceeds the maximum permitted level, we can still sweat, but this will not help cool the body to the necessary state for the normal functioning of physiological functions.
Therefore, a person who is too hot will withstand a temperature of a temperature at 40 degrees, which can lead to an increase in pulse, confusion, delirium, skin itching, loss of consciousness and coma.
But it is worth clarifying that the temperature is too high in the wet thermometer that does not destroy immediately. For a deadly result, it is likely that it will have to spend about three hours. There is no more accurate time frame: Some researchers have tried to estimate this number, but to expose people who live in such a risk for experimental purposes – ethical violations.
For the same reason, there is no evidence that 35 degrees are the exact value of the remaining temperature. According to experts, the actual figure is somewhere between +34 to +36.5 degrees C.
Air conditioner can save from deadly heat, but not everyone has access to them. And even in the areas where they are popular, the grid may be unstable. For example, Pakistan's Jacobabad city, often called the hottest on the planet, exceeded 35 degrees at least four times. In Mexico, Australia and UAE also have cities where the temperature almost reaches the limit.
Finally, some researchers believe that the threshold of 35 degrees in reality underestimates the negative impact of high temperatures to the human body. According to some experts, this figure does not take into account nuances, such as a person's age, his physical condition, the history of the disease. These factors can reduce the body's resistance to heat even at such high temperatures.
Heat is also capable of complicating existing medical problems, such as high blood pressure and heart disease. People with kidney disease are at risk, because heat affects the water level in the body, and it must be strictly monitored.
