Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
