Discovering a cure for the common cold remains even more elusive than growing hair on bald heads. So like all cold-fearing people, we practice good “respiratory etiquette” to avoid catching and spreading the bugs. First, even little kids now know to cough and sneeze into the crook of the elbow (“vampire style”). Second, “Wash your hands before eating” is now “Wash your hands every chance you get, especially after being in public places” (offices, groceries, buses, schools). Carry hand sanitizer for emergency germ-bashing.
But there’s one cold preventer we bet you don’t know about: staying physically active. In study after study, it was shown to boost the body’s ability to combat nasty cold bugs.
