As the weather turns colder, nasal congestion becomes common, often disrupting sleep. A viral post on Threads shares a unique trick to unblock a stuffy nose in just 20 seconds. While a doctor explained the science behind it, they caution that it's not a cure and offers only temporary relief.
A Threads user "_1ianc" shared that when experiencing a stuffy nose, this method can provide quick relief:
- If your right nostril is blocked: Make a fist with your right hand and tightly tuck it under your leftarmpit.
- If your left nostril is blocked: Make a fist with your left hand and tightly tuck it under your rightarmpit.
- Hold the fist tightly in the armpit for about 20 seconds or more, and your nose should clear.
Many users tested it and reported it worked. But what's the principle behind it?
Doctor Explains the '20-Second' Trick
Taiwanese otolaryngologist Dr. Zhang Jiahao commented, explaining it involves the body's autonomic nervous system:
- Key Mechanism: When skin in the armpit experiences pressure, it stimulates local sensory nerves. This triggers excitation of the contralateral (opposite side) sympathetic nervous system(known as the cutaneo-nasal reflex or axillary pressure reflex).
- Vasoconstriction: Nasal congestion is often caused by swollen blood vessels (congestion) in the nasal turbinates, narrowing the airway. Sympathetic excitation causes blood vessels to constrict. The blood vessels in the opposite-side nostril (from the pressed armpit) constrict, reducing swelling and opening up space, thus clearing the nose.
Zhang pointed out that while this method can be effective, it is not a fundamental cure. The relief is short-lived, and congestion may return shortly after the pressure is released.
Other users also shared various methods in the comments, such as "Lie on your side with the blocked nostril facing up. Keep your body still, lift your head forcefully to look at your feet" and "Maintain a normal breathing rhythm. When you finish inhaling and start exhaling, keep exhaling until you can't anymore, then slowly inhale through your nose—it will clear."
How to Use Nasal Irrigation for Congestion Relief?
For proper relief of nasal congestion, Hong Kong otolaryngologist Dr. Zhong Yaoji previously told Sing Tao Headline that nasal irrigation (using a saline rinse) can effectively alleviate symptoms but is not a cure for underlying nasal issues. It helps flush out mucus, bacteria, and allergens, reducing discomfort. However, for the root causes of congestion like colds or allergies, targeted treatment is also needed. He suggests nasal irrigation can be tried for: chronic sinusitis, allergic rhinitis, nasal infections, post-operative care, nasal deformities, or foreign objects.
Steps for Nasal Irrigation:
- Prepare saline or physiological saline solution.
- Tilt your head to one side so one nostril is higher.
- Using a neti pot or squeeze bottle, slowly pour the solution into the higher nostril, allowing it to flow out the other nostril or mouth.
- Repeat on the other side.
Besides nasal irrigation, he recommends these methods to relieve congestion:
- Avoid Allergens: If allergic to certain substances (e.g., pollen, dust mites, pet dander), minimize exposure to reduce allergy-triggered symptoms.
- Maintain Indoor Air Quality: Regularly clean your home and change bedding to reduce dust mites and mold, which can trigger allergic reactions.
- Dietary Adjustments: Drink plenty of warm water; gargle with warm salt water for a sore throat. Eat fruits rich in Vitamin C (e.g., kiwi, oranges). Avoid spicy, greasy foods.
- Maintain Healthy Habits: Exercise regularly to boost immunity. Avoid staying up late and improve sleep quality to help reduce the occurrence and severity of allergic reactions.
