Nasal irrigations are a therapy that involves washing the nasal passages with a saline solution or clean water. This treatment is used to cleanse and moisturize the nasal passages, remove secretions, and clear any obstructions or allergens present. Nasal irrigations are particularly useful for the treatment of respiratory disorders such as allergic rhinitis, sinusitis, nasal congestion, and to promote better breathing. This therapy can be performed using a syringe, a pressurized device, or specific instruments.
