Nasal congestion is a common condition that can be caused by a variety of factors, including infections, allergies, structural abnormalities, dry air, cold temperatures, bright lights, cluster headaches, hormonal changes, medications, thyroid problems, spicy foods, tobacco smoke, and stress.
Treatment:
Home remedies are usually effective in treating nasal congestion. Decongestants and antihistamines can provide quick relief, but should only be used for a few days. Saline nasal sprays and a humidifier can help to moisten the air and keep nasal passages from drying out. Drinking lots of fluids, especially hot tea, broth, or chicken soup, can also help.
For infants and younger children, a stuffy nose can be dangerous. Use a nasal bulb aspirator to remove mucus from the nose and have your child lie on their stomach to help mucus drain. You can also try saline nose drops.
If your nasal congestion is severe or does not respond to home remedies, see a doctor. They may prescribe additional medications or recommend other treatments.
