Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
