How Did Ancient Humans Go to the Bathroom in Freezing Cold?

It's 3 a.m. in the Ice Age, it's far below freezing, and your body has made a decision you can't overrule. No door, no light, no toilet, no toilet paper. So what did ancient humans actually do? In this video: • Why the cold makes you need to pee more (cold diuresis), and why it also switches off your thirst • What happens the moment you open warm fur clothing in a freezing wind • Where ancient people could go, and why the drinking water mattered most • What people wiped with before toilet paper existed • Why waste doesn't disappear in deep cold, from frozen Ice Age camps to the glaciers of Denali • How 14,000-year-old poop from Paisley Caves, Oregon, became evidence in one of archaeology's biggest debates: when humans first reached the Americas CHAPTERS CHAPTERS 0:00 3 a.m. in the Ice Age 0:53 Why the cold makes you need to go 1:27 The hidden water trap 2:17 Leaving the warm hides 3:24 Where do you actually go? 4:44 What did they wipe with? 6:21 The cleanup crew that freezes 7:34 Paisley Caves: the poop that changed the timeline 9:15 The Neanderthal evidence 9:40 The answer 10:01 Back to the shelter Watch next: Why Didn't Predators Eat Sleeping Ancient Humans?
