Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
