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. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
