Note: The heat index, also known as 'feels like' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
