Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
