How Did Humans Stay Clean Before Soap?

If you stopped showering today, you’d smell terrible by next Tuesday. But for 99% of human history, soap didn't exist, so why weren't our ancestors covered in filth and disease? In this video, we explore the fascinating (and slightly gross) science of ancient hygiene. From "peacekeeper" bacteria that eat sweat to the Roman's genius method of cleaning with oil and metal scrapers, we reveal how our ancestors stayed "functionally clean" without a single bar of soap. We also dive into the Hygiene Hypothesis: Is our modern obsession with sterilization actually the cause of acne, eczema, and severe allergies? Discover the "living shield" on your skin that modern chemistry is trying to destroy.
