Treatments that relieve cold and sinus pressure include nasal irrigation, warm facial compresses and using a humidifier, according to WebMD. Keeping the head elevated during sleep and increasing fluid intake can further ease cold and sinus pressure.
Colds cause sinus pressure when the membranes lining the nasal passages become inflamed, notes WebMD. The membranes swell and increase mucus production in order to remove the virus causing the irritation.
Medications, such as decongestants and nasal steroids lessen the cold and sinus pressure, according to the Cleveland Clinic. At-home treatments relieve cold and sinus pressure by keeping the nasal passages moist and allowing them to drain.
Flushing out nasal passages with an irrigator, such as the Neti Pot, helps, advises the Mayo Clinic. Irrigators work by pouring water or warm saline solution into one nostril and allowing it to drain out through the other. This removes mucus, germs and other debris while keeping the passages moist. To keep passages moist throughout the day, one can use a nasal saline spray.
Running a vaporizer or humidifier to improve the humidity in the environment also relieves pressure, recommends WebMD. One can also breathe in the steam from a hot shower or from a bowl of boiling water.
