Gargle, gargle, gargle
Grandma was right: Gargling can help, maybe even as a preventative. In a single study from Japan, some volunteers were asked to regularly gargle with water while others were not. After 60 days, the gargling group had a nearly 40 percent decrease in colds compared with the control group. To soothe a sore throat, the Mayo Clinic advises gargling with one quarter to one half of a teaspoon of salt mixed with eight ounces of warm water. (The salt will draw out excess fluids from your body.) These are silent signs that stress is making you sick.
The term “common cold” is a bit of a misnomer
Common implies that there’s a single ordinary pathogen to blame for your runny nose, coughing, and mild fatigue. Actually, there’s a huge array of viruses—more than 200 of them—that induce colds, each with its own means of evading your body’s defenses. For this reason alone, it’s unlikely that a catchall “cure for the common cold” will ever be found. These are crazy cold symptoms you probably never knew about.
