It’s a lovely, clear fall day in southern Wisconsin, today. Seasonal temperatures, sunshine, and trees outside our windows here at work are turning shades of yellow, plum and red.
While the weather has been mild, even above average for September (today is October 1), cold season struck early here. In our work group, all suffered mild to strong symptoms: sore throat, congestion, fever, and time away from work, ‘sleeping it off’.
While there is no cure for the common cold, we all employ a therapy or two for easing the pain of symptoms. Growing up in small town Midwest, during the 1970s, the single remedy most often prescribed by our head nurse, Mom, was gargling with warm salt water.
This treatment was not only to alleviate cold symptoms, but dispensed in an effort to ward off kids that might think they needed a day in bed instead of in school. A complaint of “my throat hurts” was met with the command, “Have you gargled with warm salt water?!”
This of course was not the sympathetic ear a child hopes for. But in The New York Times this past week, a note that, as you already know:
Mom was right.
The New York Times article highlighted research published in 2005, in the American Journal of Preventive Medicine, which proved that gargling with water goes beyond soothing symptoms; it can in fact help prevent upper respiratory tract infections.
For this study, 387 healthy volunteers between ages 18 and 65 participated for 60 days, during the winter cold and flu season. There were two gargling groups: one that gargled with water, the other a dilute povidone-iodine solution. Both groups were asked to gargle at least three times daily. The control group followed their usual routine.
Some of the study participants did contract upper respiratory tract infections, but the infection rate for those gargling with water was nearly 40% less than for the control group. The povidone-iodine group also saw a lower rate of infection, though not as impressive as that of the water gargling group.
Use of the salt water gargle is directly supported in a new book from the Mayo Clinic, to be released this month, “The Mayo Clinic Book of Home Remedies: What to Do For The Most Common Health Problems” (October 2010).
Their online resource provides this recipe for a salt water gargling solution:
“A saltwater gargle — 1/4 to 1/2 teaspoon (1.2 milliliters to 2.5 milliliters) salt dissolved in an 8-ounce (237 milliliters) glass of warm water”—to temporarily relieve the symptoms of a sore throat.
Mom would add that the water should be “as warm as you can stand it”. You’ve heard the expression, “Tough love.”
The science behind the gargle remedy is pretty basic. Your throat is sore, and warmth of the solution gargle soothes the sore tissue. Using salt water may actually help draw some fluid out of the swollen, sore throat lining, easing inflammation and lessening pain.
Mayo Clinic goes on to note that those seeking a more palatable remedy (and who eschew spitting) can try warm water with lemon and honey. It’s ok to swallow this mixture.
While I’m neither nurse nor medical professional, may I add one new-agey twist to Mom’s favorite remedy? Bear with me, I’m a total whimp when a cold strikes. Parents and loved ones everywhere will benefit from one little phrase, delivered before the warm salt water gargle.
Try this first: “I’m sorry that your throat is so sore. “
Then, lay Mom’s remedy on them—“Have you gargled with warm salt water?”
