 The immune system is only trying to help, of course. When we get cut a cut or wound, immune cells rush to the area to fend¹ off foreign particles that might cause infection. And some inflammation is inevitable². But too much inflammation is bad–it can cause diseases like rheumatoid arthritis³. So according to the study, skin bacteria dampen the immune cells’ activity enough to prevent excessive inflammation without hampering⁴ the immune system’s ability to fight infection. This doesn’t prove the hygiene⁵ hypothesis, exactly. But it does show that bacteria on, and maybe in, our bodies help the immune system do its job without going out of control.
