Note: The heat index, also known as 'felt air temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
