Note: The heat index, also known as 'feels like' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
