Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses. Take caution! The UV rays from the Sun gain strength from sand and water reflections.
