Why Wednesday: Why Does Skin Wrinkle in Water?

It's been one of the sunniest Summers on record, and I'm here for it. Summer has certainly brought the heat, and of course, the questions! Inquiring preschool minds want to know.

  • Why does humidity make mommy's hair frizzy?

  • What does it mean to 'get a tan'?

  • How does chlorine keep pools clean?

  • Is the sun as hot everywhere in the world?

  • Why does our skin wrinkle if we're swimming in water too long?

All valid questions, and personally, I would love to get to the bottom of the first one! The question that has my 4 year-old feeling most intrigued is the last one: Why does our skin wrinkle in the water? Let's splash into the answer...

According to

"'s thought that when moisture is detected [on skin], your nervous system tells your blood vessels to contract, creating the bumpy surface. The theory goes that having creases on your fingers and toes makes it easier to pick things up in slippery wet conditions."

Sounds like an evolutionary trait? Our bodies do some pretty amazing things! If only our nervous system could tell our hair follicles not to frizz in humid conditions...I would save a lot of money on hair products. Am I right?

Until next time, keep those little minds active!
