Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
