Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical 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 are particularly meaningful for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
