00:00 The podcast episode discusses the topic of human hygiene and the hosts share personal anecdotes about their showering habits.

05:15 The history of human hygiene dates back to unicellular life and the impulse to rid oneself of parasites and pathogens, although the reasons for bathing have varied throughout history.

10:42 Prehistoric people cut their hair and body hair to combat lice, and combing hair was a way to care for it before the invention of shampoo.

16:01 People throughout history have had different views on body hair, with some cultures plucking hair while others embrace it, and the practice of removing pubic hair dates back to ancient Egypt.

21:26 Bathing has been practiced for a long time, with early forms of bathing involving submerging oneself in water or using a small amount of it, and it was often a social activity rather than for cleaning purposes. Bath houses were prevalent in various civilizations, including the Indus civilization and the Roman Empire, with estimates suggesting that Baghdad had around 60,000 bath houses in the Middle East around 1000 CE.

26:57 Bath houses were typically separated by gender, but there were some co-ed bath houses, such as a traditional Turkish bath, where people would bathe together, often wearing swimsuits, and it was a relaxing and enjoyable experience.

32:36 Humans have always had the impulse to groom themselves, and as plumbing improved and germ theory emerged, people began to prioritize cleanliness and hygiene for the sake of their health.

38:08 In ancient Egypt, instead of bathing and washing, people would just cake perfumes and smells onto everything to mask body odor, which would have been unpleasant.

43:41 The use of deodorant and antiperspirant to counter body odor is a relatively new invention, dating back to the 20th century.

49:11 The invention of antiperspirant, specifically Odorono, was initially unsuccessful until advertising and marketing campaigns targeted women's fears and self-consciousness about body odor, resulting in a significant increase in sales.

54:42 People have been trying to combat bad breath for a long time, using plants, twigs, and powders, but they also discovered that abrasive tooth powders and toothbrushes made with hog bristles could damage teeth and gums.

01:00:04 The hosts discuss their personal experiences with skincare products and the effects they had on their skin.
