Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Limit your exposure to direct sunlight during these hours. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Alert! Sand and water increase UV exposure due to their reflective properties.
