Note: The heat index, also known as 'felt air temperature' or 'feels like', is the result of factoring in humidity to the air temperature, indicating perceived warmth. 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 of high significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
