Have you ever wondered why wrinkles develop on fingers when they are soaked in water for an extended period? In reality, the culprit behind this phenomenon is the nervous system.
The process of developing wrinkles on fingers after prolonged immersion in water is referred to as ‘aquatic wrinkling’ in English. Initially, it was thought that wrinkles occurred due to the absorption of water by the skin, but recent studies have debunked this notion.
The actual reason for the formation of wrinkles on fingers in water is the activity of the nervous system. When submerged in water for an extended period, the nervous system brings about a slight change in the blood vessels in the upper layers of the skin. This change causes the skin to contract, resulting in the visible appearance of wrinkles.
It is believed that this reaction occurs to enhance grip in wet environments and assist in handling objects more effectively.
Furthermore, this process of developing wrinkles is governed by an autonomous nervous system. It does not occur in individuals with any sensory nerve impairment in their fingers. Nevertheless, it is a temporary and harmless response that occurs after the skin becomes dry.
