Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
