Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
