There are many ways to clear a blocked nose, including using a vaporizer, taking a hot shower and using a saline solution. Drinking plenty of fluids can also help, as stated by WebMD.
Nasal congestion can occur when something irritates the tissue inside the nasal cavity. This can include allergies, infections, dry air and polyps, according to Mayo Clinic.
The treatment for clearing a blocked nose should not include drying out the sinuses, as this can cause further blockage. Other ways to clear the blockage is to use warm compresses over the nose and face or using over-the-counter products such as a Neti Pot.
