The increase in temperature in our country and throughout the world; began to worry not only the elderly or those with health problems, but also healthy youth and adults.
Scientists were alarmed about the increased temperature extremes combined with high humidity and sought the upper temperature limit for human safety. Unfortunately, this temperature is much lower than we thought.
Research on the upper temperature limit has raised concerns.
In a study conducted in 2010, it was said that the upper limit for the human body at 100% humidity, 35°C or 50% humidity, is 46.1°C, beyond which the body can no longer cool itself by evaporating sweat to maintain temperature.
This limit, recently tested on humans in laboratory settings, has raised even greater concern.
To investigate the upper temperature limit for our safety, the subjects were placed in a room where they could do their daily work. Healthy adults who come to the Noll Lab at Penn State University; He could move enough to simulate daily activities such as showering, cooking, eating.
Researchers; In hundreds of separate experiments, they slowly increased the temperature or humidity in the room and observed that the subject’s temperature began to rise.
Once the critical perimeter is crossed, dangers begin to appear.
The combination of temperature and humidity at which our internal temperature begins to rise continuously is called the ‘critical environmental limit’. Below this limit, the body can maintain a relatively constant core temperature for extended periods of time. Above this limit, the temperature rises continuously and the risk of heat-related illness increases with prolonged exposure.
When the body is overheated, the heart has to work harder to pump blood flow to the skin to dissipate heat, and also reduces bodily fluids when we sweat.
As a result of this research, it was seen that the upper environmental limit was even lower than 35 degrees.
New research suggests the upper limit is 31°C at 100% humidity or 38°C at 60% humidity. As a result, we need to be more careful than we anticipated in hot weather.
After their latest research, experts now want to test older men and women to see what the upper limits of safety are. The upper temperature limit for the elderly will likely be much lower due to the increased risk of heart disease and respiratory problems.
Together we will see the effects of the increase in air temperatures on us.
This research is very important because as the Earth’s average temperature continues to increase, heat waves will become both stronger and more intense, and we don’t yet know exactly how this will affect human health.
