Note: The heat index, also known as 'real feel' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
