Note: The heat index, also known as 'feels like' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 primarily vital for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
