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. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
