Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
