Note: The heat index, also known as 'felt air temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. 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. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
