Heat index

During May, the heat index is appraised at a scorching 41°C (105.8°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Heat index determinations are made taking into account the shade and light air movements. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
