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. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are primarily vital for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
