It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
