How do you see reactivity to house dust, air pollution, stuff like asbestos and adjacent construction materials etc. ? Then I'd assume the living ecosystem also shifted from mostly open air to indoor insects, i.e. "life finds a way"
We sure aren't exposed to the same things as 4 centuries ago, but I can't imagine we're living a what anyone would call a "clean" environment.
- ricardobeat 2y agoThose are not microorganisms, and don’t necessarily trigger your immune system in the same way.
- jnwatson 2y agoDust allergies are extremely common these days but you can't have an (IgE mediated) allergy to asbestos or smog. Generally the immune system reacts to biological substances. We're vastly more sterile from a germ perspective. The term "hygiene hypothesis" is apt.
- autoexec 2y agoWe're a very different kind of dirty. We've got microplastics in our organs, and pesticides, PFAS, and other pollutants in our blood. People in the olden days got their hands dirty chopping down trees and building solid wood tables while today we keep our hands clean by buying flat-pack furniture that out-gasses formaldehyde into our homes and our lungs. We're much dirtier than the people were a long time ago, only it's mostly on the inside. The filth in our bodies doesn't wash off with soap.
