7. Jacket

Okay, so you’re washing your hands properly now, but how about the “second-skin” of your outer layer of clothes? That’s the word Tracey Evans, PhD, a medical researcher and science writer for Fitness Savvy uses to describe one’s coat or jacket.

She points out that a jacket often touches all sorts of germ-packed surfaces such as elevator walls and countertops, where they “will pick up respiratory droplets, transfer from microorganisms from a till to a sleeve, etc.” Evans recommends always getting rid of these “second-skins” upon arriving home, and washing them more often than you might otherwise.
