Heat index

During September, the heat index is evaluated at a very hot 38°C (100.4°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
