The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
