Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children.

Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat.

Rising body temperatures due to excess heat retention could signify impending heat disorders.
