Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
