Note: The heat index, also known as 'real feel' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

The reflection of sand and water notably intensifies UV rays from the Sun.
