Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity.

Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
