Keeping the nasal passages moist by showering, using a humidifier or vaporizer, breathing in steam from a pot of hot water, using saline sprays and drops, and flushing the nasal passages with salt water using a neti pot or syringe are some home remedies for nasal congestion, states WebMD. Drinking plain water, juice, clear broths and warm lemon water with honey all loosen congestion, states the Mayo Clinic.
Inflammation of the blood vessels in the sinuses causes nasal congestion, according to Healthline, so chicken soup's anti-inflammatory properties may relieve congestion while increasing the movement of mucous, notes the Mayo Clinic. The menthol in peppermint tea, according to the Dr. Oz Show, can open nasal passages and thin mucous, while the steam from the tea and simply drinking warm liquid can increase the rate the mucous is cleared. WebMD explains that a small dab of menthol applied beneath the nose also works to open nasal passages. Keeping the head propped up on several pillows at night and applying warm compresses to the face can open up nasal passages and ease the discomfort of congestion, notes WebMD. The site also suggests the use of over-the-counter medications, such as decongestants, antihistamines and pain relievers.
