But wait—there’s a sneaky way lemon actually helps. That sour, puckering sensation forces your mouth to produce a tidal wave of saliva. That saliva? It dribbles down your throat, thinning out the mucus that’s currently staging a coup in your sinuses. Think of it as a biological Slip ‘N Slide for your congestion.
Hot lemon water also inhales steam into your nasal passages, which is basically a free spa treatment for your infected face. The heat alone can soothe a sore throat better than a stern lecture from your mother. It’s not curing the virus, but it’s making the virus’s rental property—your nose—a lot less comfortable for it.
The Antiseptic Illusion
Some folks swear lemon kills bacteria because “it’s acidic!” Yes, pure lemon juice can destroy microbes on a cutting board. But your stomach is already a bathtub of hydrochloric acid—lemon’s a drop in that ocean. Applying it to a raw throat is like trying to put out a house fire with a squirt gun filled with Gatorade.
Lemon: Health Benefits, Nutritional Properties, and Precautions
Surprising fact: lemons contain citric acid, which is actually a preservative. You’re basically preserving your own illness in a tangy brine. At most, it might inhibit some bacteria in the mouth, but the flu virus doesn’t care about your fancy pH. It’s laughing at your garnish.
