Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for 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 that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
