Note: The heat index, also known as 'apparent temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
