Note: The heat index, also known as 'felt air temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Tightly woven clothing, when worn loosely, shields effectively against the Sun.
