Heat index guidelines indicate values are for light wind scenarios and shaded regions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear. Note! The Sun's UV radiation gets intensified with the reflection from sand and water.
