Your Pruney Fingers After After a Bath Always Wrinkle the Same Way, Study Reveals

Pruney fingers and toes after a long time in the pool or the bathtub are one of those things we all expect but couldn’t explain scientifically until recently. In 2023, Binghamton University biomedical engineer Guy German and colleagues found that this happens because the blood vessels in our digits contract when we spend too much time in water. Then a kid asked a brilliant question that triggered a whole new research project. “A student asked, ‘Yeah, but do the wrinkles always form in the same way?’ And I thought: I haven’t the foggiest clue!” German explained in a Binghamton University statement. “So it led to this research to find out.” German and Rachel Laytin, a former graduate researcher at the university’s Biological Soft Matter Mechanics Laboratory, revealed that the answer is, simply put, yes: pruney fingers always seem to wrinkle along the same patterns. They detailed their work in a study published in February in the Journal of the Mechanical Behavior of Biomedical Material ... Read full article.
