Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 highly critical to babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
