Note: The heat index, also known as 'real feel' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
