Note: The heat index, also known as 'real feel' or 'feels like', quantifies the warmth felt when relative humidity is considered. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital 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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
