Know that the heat index computations account for shaded terrains and slight winds. 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 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
