Wikipedia suggests a typical human has ~ one trillion bacteria on their skin. That’s orders of magnitude more than a cell phone and many many orders of magnitude more than a toilet seat. They typically don't cause disease and may offer benefits. It kind of bothers me that there’s this common belief that microbes are bad and the more sterile our skin is, the healthier we will be. There seems to be a push to reduce bacteria of all kinds on our skin. Here’s one example I know of regarding beneficial bacteria and acne. This is from Science: Maybe if you have acne, you should rub faces with someone with healthy skin. Preferably someone of the opposite sex. Anyway, I bet there are a lot of benefits to having the right bacteria on your body. Wikipedia states that most bacteria are in the epidermis or hair follicles so perhaps they are difficult to wash off. Hopefully the good bacteria don’t get destroyed by that anti-bacterial stuff in those dispensers, but I don’t know. Not too sure where I’m going with this but I’d be interested in comments, especially around the benefits these bacteria have on our skin and our health in general. What bacteria are they and what benefits can they provide?
