Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
