Note: The heat index, also known as 'feels like' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
