The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
