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. 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 are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
