Boddities | Episode 7 | Why do our fingers get wrinkly in water?

The video explores the scientific mystery behind pruney fingers, explaining how water permeates the skin, triggering the sympathetic nervous system to constrict blood vessels, leading to wrinkling. It discusses the unique properties of glabra skin on fingertips and suggests an evolutionary purpose for improved grip in wet conditions. The video concludes with practical implications of this phenomenon.
