Use saline nasal spray or saline rinse (sterile/distilled water only)
Steam inhalation or a hot shower to loosen mucus
Stay well hydrated
Use a humidifier, especially at night
Try warm compresses over the nose and cheeks
Sleep with your head elevated
Blow your nose gently and often; avoid forceful blowing
Use a nasal decongestant spray (oxymetazoline) for up to 3 days only
Consider an oral decongestant if safe for you (avoid if you have uncontrolled high blood pressure, heart rhythm problems, or certain medical conditions)
If allergies are likely, use an antihistamine (e.g., cetirizine or loratadine) and/or an allergy nasal steroid (e.g., fluticasone or budesonide)
Avoid known triggers (dust, smoke, strong odors, cold air)
Keep indoor air clean; use HEPA filtration if available
Check for medication-related congestion (some decongestants can worsen rebound congestion if overused)
If symptoms are severe or you have sinus pain/pressure lasting more than 10 days, seek medical care
Seek urgent care if you have trouble breathing, chest pain, severe headache, swelling around the eyes, high fever, or symptoms of a serious infection
