Note: The heat index, also known as 'apparent temperature' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
