People have been gargling with salt water for ages. It cleans the mouth, soothes the throat, and may prevent upper respiratory infections. Maybe your mother suggested it as one of her sore throat remedies. Turns out it was good advice. Now there is scientific evidence that a saline solution can help ease discomfort in your dry, scratchy throat. Even the Mayo Clinic recommends a salt solution gargle as a way to treat the symptoms of a sore throat. So gargle salt water every morning to get that fresh, clean feeling and take on the day.
