When referencing the heat index, its values are suitable for shady environments and light breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', determines the feeling of heat when you account for the relative humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. 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. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. 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. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
