The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
