It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. 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. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
