Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
