How Did Ancient Humans Deal With Body Odor? | ink Decode

You lift your arm and take a breath. Sharp. Sour. Unmistakable. For roughly 300,000 years, no human ever touched deodorant, soap, or a hot shower. So what did your ancestors actually smell like, and did they even care? In this video, you'll see what's really behind body odor: two kinds of sweat glands and a garden of bacteria living under your arm. You'll learn how the famous sweaty T-shirt study showed that your nose can read someone's immune system, and why fear has a smell other people can pick up. Then you'll travel back in time to see how your ancestors managed their scent: bug-repelling leaf beds at Sibudu Cave, ash-lined bedding at Border Cave, woodsmoke, ochre paste, and the smoke baths still used by the Himba people today. Finally, you'll find out when body odor stopped being information and became something to be ashamed of, and why the answer has more to do with advertising than biology.
