For clarity, heat index numbers account for light winds and areas under shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Execute all crucial precautions. Warding off sun exposure is non-negotiable. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. A sunscreen boasting a minimum SPF of 30 should be generously applied and reapplied even on cloudy days, post swim or outdoor exercise. Take note! The UV strength of the Sun elevates when reflected off water and sand.
