Why does perceived pain intensity increase dramatically when a burn damages both epidermis and dermis?

💡 Explanation

Increased pain results from burn damage exposing and activating more temperature-sensitive Transient Receptor Potential (TRP) channels in the dermis. Because more nociceptors are triggered, leading to an amplified signal transmission to the brain, therefore the perceived pain is more intense, rather than being solely due to changes in inflammation or nerve conduction.
