The reason I ask is because our bodies as human beings have an amazing immune system and unless you have an autoimmune disease, naturally our bodies can heal ourselves from sickness.
I’m speaking primarily on the common cold, Influenza or anything similar like it, including even COVID.
Do you prefer natural insulation against the cold over clothes?
One is immune the other is thermal regulation but nice attempt at “related comparison”
“One is one thing and one is a different thing” is your rebuttal? Nice.
