Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
