Why do fingernails grow faster than toenails? Science Short
Season 7
Episode 1656
Published 4 days, 17 hours ago
Description
It’s the world’s slowest race: fingernails versus toenails.
They’re made from the same tough stuff and grow in much the same way, so why do our fingernails race ahead while our toenails trail behind? Christie investigates the tiny nail factories hidden beneath our skin, discovers just how slowly nails really grow, and finds out how blood flow, warmth and all the work done by our busy fingers might give fingernails an unfair advantage.
