Curious Kids: why do our toes and fingers get wrinkly in the bath?

Research output: Contribution to journalOnline ResourceEducation


[Extract] The truth is scientists aren’t exactly sure why our fingers and toes get wrinkly in the bath. Here’s what we do know:

it happens when we stay in the bath for more than about five minutes, but can happen faster if the water is hotter. In warm water (about 40 degrees Celsius), the skin on your hands and feet can wrinkle in only 3.5 minutes
it also happens to macaque monkeys
it only happens on our hands and feet. The rest of our skin doesn’t tend to wrinkle in this way.
