“…This wrinkling was previously thought to be the result of osmotic swelling of the stratum corneum, the outermost layer of skin [1]. However, more recent evidence has shown that it is in fact due to a reduction in the volume of the fingertip pulp, caused by vasoconstriction, which in turn is controlled by the autonomic nervous system [2][3][4][5]. In combination with the mechanical properties of the glabrous finger skin, this reduction in pulp volume results in the typical pattern of ridges and valleys on the tips of fingers and toes [1].…”

Water-induced finger wrinkles improve handling of wet objects

Upon continued submersion in water, the glabrous skin on human hands and feet forms wrinkles. The formation of these wrinkles is known to be an active process, controlled by the autonomic nervous system. Such an active control suggests that these wrinkles may have an important function, but this function has not been clear. In this study, we show that submerged objects are handled more quickly with wrinkled fingers than with unwrinkled fingers, whereas wrinkles make no difference to manipulating dry objects. These findings support the hypothesis that water-induced finger wrinkles improve handling submerged objects and suggest that they may be an adaptation for handling objects in wet conditions.

“…The second explanation is that neural activity enhancement leads to vasoconstriction. In recent years, more and more evidence [13][14][15][16] shows that the phenomenon of the sympathetic autonomic nerves constricting blood vessels to lower finger volume is the main cause of wrinkles. The control of wrinkles by the sympathetic nervous system is considered to be a clinical indicator of autonomic function.…”

Grip Performance Affected by Water-Induced Wrinkling of Fingers

Gripping an object is one of the most common actions in our daily lives. The hairless human fingers and toes become wrinkled after interacting with water for a period of time. This wrinkling phenomenon affects finger grip performance and influences the safety and convenience of everyday life. In order to study the impact of wrinkled fingers on grip performance, the moisture of the finger was measured using a Corneometer Ò CM825; the real-time fingertip contact area on the moving surfaces was captured via the ink method and a high-speed camera; and the coefficient of friction between the fingertip and the contact surfaces in the dry, wet and water-submerged states was evaluated using a tribometer (UMT-2). In particular, a simple compressed spring grip experiment was designed to quantify and verify the relationship between the gripping force and the friction force of an unwrinkled/wrinkled fingertip and contact PET surfaces. The experimental results revealed that how finger wrinkles affect grip action.

“…This vasoconstriction appears to occur most readily at a temperature of around 40˚Celsius, or the temperature of a warm bath [2]. People with autonomic neurological conditions including Parkinson's, cystic fibrosis, congestive heart failure or diabetic neuropathy may show abnormal or asymmetric wrinkling in the affected parts of the body [3][4][5].…”

Water-immersion finger-wrinkling improves grip efficiency in handling wet objects

For most people, immersing their hands in water leads to wrinkling of the skin of the fingertips. This phenomenon is very striking, yet we know little about why it occurs. It has been proposed that the wrinkles act to distribute water away from the contact surfaces of the fingertip, meaning that wet objects can be grasped more readily. This study examined the coordination between the grip force used to hold an object and the load force exerted on it, when participants used dry or wrinkly fingers, or fingers that were wet but not wrinkly. The results showed that wrinkly fingers reduce the grip force needed to grip a wet object, bringing that force in line with what is needed for handling a dry object. The results suggest that enhancing grip force efficiency in watery environments is a possible adaptive reason for the development of wrinkly fingers.

Reduced water induced skin wrinkling in congestive heart failure

Abstract: Water immersion skin wrinkling (WISW) of the fingertips may reflect central autonomic function. We found lower WISW in 60 heart failure patients versus controls (1.6±0.67 vs. 2.5±1.1, p<0.001), linking a cardiovascular disorder to reduced WISW.
