It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Guard oneself from overexposure. Defence against sun injury is vital. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration. Caution! The reflection of sand and water significantly increases the intensity of the Sun's UV radiation.
