What is the normal internal body temperature that the skin helps to regulate?

The normal internal body temperature that the skin helps to regulate is commonly recognized as 98.6°F. This temperature is averaged from various studies and represents a healthy body's metabolic state. The skin plays a crucial role in maintaining this temperature through processes such as sweating to cool down or constricting blood vessels to retain heat, thus ensuring that the internal environment remains stable despite external changes. This regulation is vital for optimal function of the body's systems, making 98.6°F a significant benchmark in human physiology and health assessments.
