Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
