One effective remedy that helps people drain their sinuses is applying steam, according to Everyday Health. An individual can breathe in a sufficient amount of steam by taking a warm shower or leaning over a sink of hot water and placing a towel over her head, notes Healthline.
Steam helps drain the sinuses by thinning out the mucus in the nose and reducing redness, swelling and other signs of inflammation. Saline spray provides similar relief from sinus infections. Fluids such as water, tea, juice and sports drinks can help by keeping the body hydrated. Soup can also soothe the nasal passages and alleviate the pain of a sore throat, states Healthline.
