If you have a cold and your nose is blocked and not breathing well, here are some things you can do. Use a saline nasal spray to help moisten and clear the nasal passages. Inhale steam from a bowl of hot water or take a hot shower to loosen congestion. Place a warm compress over your nose and forehead. Elevate your head while sleeping to help drainage. Drink plenty of fluids to keep your body hydrated. Try over-the-counter decongestant medications if needed, but follow the instructions carefully. If the congestion persists or is accompanied by severe symptoms, consult a doctor. ????
