It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 extremely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
