Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
