Is dirt bathing a thing? I noticed every mammal or bird on Earth likes to roll around in dirt occasionally except for us human saps. It's supposed to help manage parasites I think but I think it's more likely to do with increasing native phage exposure. Something like ten million phages in every gram of dirt which you wouldn't typically have access to unless you roll around in it for a bit.

same for skinny dipping. Hundreds of millions of phages in every millilitre of water which you get totally immersed in. When I was a kid it always amazed me how all the scuffs, scrapes and cuts would magically just heal after spending a hour or two in the sea.

Obviously take a shower afterwards or before you put your clothes back on. Can you also maybe buy special forest dirt you can rub yourself down with if you're in a city.
