To stop a runny nose in minutes, some quick and effective methods include:

• Blowing the nose thoroughly to clear out mucus temporarily.
• Using hot steam inhalation or placing your face above steam to loosen mucus.
• Drinking a hot beverage like tea to soothe nasal passages.
• Applying gentle pressure on specific points on the face (such as under the cheekbone) to open nasal passages, a technique shown to help relieve congestion quickly.
• Using saline nasal sprays or rinsing with a neti pot to clear nasal passages.

These methods can provide fast relief by clearing or thinning mucus, opening nasal passages, and soothing inflamed nasal tissues.
