Hurray! Maybe the fact that I am not the world's best at keeping our home clean is not such a bad thing after all.
Apparently the more you clean does not mean the less germy your house is.
In a new study in Nature Microbiology, Laura-Isobel McCall and her co-authors found that the fungal diversity was actually higher in urban homes, and it might be because of peoples' cleaning products and urban lifestyles.
"Maybe they're scrubbing away all the bacteria and now you have this big open surface for fungi to grow on; maybe [the fungi] are also becoming more resistant to the cleaning agents that we use," she says.
Many antibacterial cleaning solutions and sanitizers specifically target bacteria, which could clear space for other kinds of microbes to flourish. Fungi also have thick cell walls, which may make them harder to kill. And urban homes are designed to isolate people from the outside; they block out light and trap CO2, which could be creating hospitable environments for fungus to grow, McCall says.
Some of the bacteria we are getting rid of are probably helpful to humans, like the bacteria in our guts.
