The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
