Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
