Understanding the Wrinkling Phenomenon after Water Immersion

This chapter delves into the misconception surrounding the wrinkling of fingertips and toes after water immersion, explaining that it is not due to dehydration but rather a phenomenon related to osmolarity. The speakers discuss a study that tested varying tonicity solutions on hands to demonstrate the relationship between tonicity and wrinkling, with no wrinkling observed in a 20% saline solution.
