Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. A broad-spectrum sunscreen of SPF 30+ should be used liberally and reapplied every two hours or post an outdoor workout or swim. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
