Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
