Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels.

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 primarily vital for children. 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
