Note: The heat index, also known as 'feels like' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
