Nasal irrigation, commonly performed with a neti pot or squeeze bottle using a saline solution, is one of the oldest home remedies for sinus and respiratory comfort, with roots in the Ayurvedic tradition. Research suggests that regular saline nasal rinsing can help relieve symptoms of chronic sinusitis, allergic rhinitis, and upper respiratory congestion by physically flushing mucus, allergens, and irritants from the nasal passages. Studies indicate that nasal irrigation may reduce the need for over-the-counter decongestants and improve overall quality of life for people dealing with recurring sinus issues. While generally considered safe when performed with properly prepared saline solution and distilled or previously boiled water, those with frequent ear infections or compromised immunity may want to consult a healthcare provider before starting regular use.
