Take into consideration that the heat index values are calculated for shade and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes.

Boost your sun resistance with garments that are densely woven yet spacious.
