Note: The heat index, also known as 'apparent temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for 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.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. 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. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
