Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
