Thermal sensation refers to the perception of temperature through the skin and other sensory receptors in the body. It allows individuals to detect whether an object or environment feels hot, cold, or neutral. This sensation is crucial for maintaining body temperature and avoiding harmful conditions, such as frostbite or burns. The sensation is primarily mediated by specialized nerve endings called thermoreceptors, which respond to changes in temperature. These receptors send signals to the brain, where the information is processed, allowing a person to react appropriately. Factors like humidity, airflow, and clothing can also influence thermal sensation.
