The Causes of Nasal Congestion Revealed: Why Is Only One Side Blocked?
The nose is a very important organ in our respiratory system. It not only plays a key role in breathing but also protects us and gives us our sense of smell. However, nasal congestion is a problem many people face — especially congestion on one side. What causes one-sided nasal congestion, and how can it be solved? Let's explore.
Causes of and solutions for one-sided nasal congestion
There are many causes of one-sided nasal congestion, including a deviated septum, nasal polyps, fungal sinusitis, and foreign objects or tumours in the nose. These can all block one side of the nasal cavity and cause congestion.
For one-sided congestion, we can try the following methods to relieve it:
1. Working with the nasal cycle: the body has a "nasal cycle" mechanism that makes the two nostrils take turns becoming congested, causing one-sided congestion. This is a normal physiological phenomenon and usually improves on its own after a while. We can try massaging the Yingxiang and Shangyingxiang acupoints to stimulate the sympathetic nerves of the nose, making the nasal lining and blood vessels contract and relieving congestion.
2. Armpit pressure: pressing under the armpit can improve congestion on the other side by stimulating the connected sympathetic nerves. This method is simple and effective and needs no tools — just gently press under the armpit with your hand or an object for 30 seconds to 1 minute.
3. Inhale peppermint essential oil: peppermint oil has a cooling nature that can contract the nasal lining and blood vessels, relieving congestion. You can gently apply peppermint oil around the nostrils or use a peppermint nasal inhaler. But be careful not to overuse it, or it may have the opposite effect.
The many causes of nasal congestion
Besides the common causes of one-sided congestion above, the factors that cause nasal congestion are actually quite wide-ranging. Besides common conditions such as colds and allergic rhinitis, systemic diseases such as autoimmune diseases and blood disorders, and habits such as smoking and drinking, can also cause congestion.
Structural abnormalities of the nasal cavity and sinuses, such as a deviated septum and nasal polyps, can also cause congestion. In some rare cases, nasal tumours or nasopharyngeal cancer may also present as one-sided congestion.

Risk factors for nasal congestion
Although most cases of nasal congestion aren't very serious, some situations need special attention. For example, long-term one-sided congestion may suggest an underlying condition such as a fungal infection or a nasal tumour. And symptoms such as nosebleeds or an unusual smell may also be signs of disease.
In addition, people with weaker immune function, such as those with diabetes or blood disorders, need to be especially careful when they have unusual congestion, as there may be serious complications.
Diagnosing and treating one-sided nasal congestion
When faced with one-sided congestion, we first need to understand the cause. Doctors usually perform an endoscopy to examine the nasal cavity and sinuses carefully. If structural abnormalities or tumours are found, further treatment such as surgery may be needed.
For more common causes of congestion, such as colds and allergic rhinitis, doctors prescribe medication according to the condition. They also advise patients to adjust their habits, such as avoiding allergens and quitting smoking.
Ways to relieve nasal congestion
Besides the diagnosis and treatment above, we can also try some simple ways to find relief:
1. Warm compress: applying a warm towel to the nose improves blood circulation and relieves congestion.
2. Steam inhalation: use a steamer or boiling water for steam inhalation to help moisturise the nasal lining.
3. Drink plenty of water: staying well hydrated helps keep the nasal lining lubricated.
4. Acupoint massage: massaging Yingxiang and Shangyingxiang stimulates the sympathetic nerves and improves congestion.
In short, although nasal congestion is common, its causes are varied. We need to pay special attention to one-sided congestion in case it hides a serious condition. With timely diagnosis and treatment, combined with some simple and effective relief methods, we believe you can improve nasal congestion and restore good breathing.
Here's a table of ways to improve nasal congestion:
Method | Description |
Warm compress on the nose | Gently place a warm towel on your nose. The warmth helps the nasal lining shrink and makes breathing easier. |
Humidify the air | Use a humidifier to increase air humidity, or apply a warm towel of suitable temperature to your nose to increase moisture inside the nose and ease inflammation of the lining. |
Clear out dried mucus | If you can't blow out mucus when congested, place a cup of hot water in front of your nose. The steam thins nasal secretions and increases airway moisture, helping you clear mucus. |
Acupoint massage | Massage acupoints such as Baihui and Dazhui to reduce triggers of congestion and sneezing, helping regulate the body internally to achieve a therapeutic effect. |
Deep breathing | Do deep breathing exercises to help ease congestion and improve nasal airflow. |
Use a nasal spray | Steroid nasal sprays effectively relieve nasal allergy symptoms. They need to be used regularly and take effect after 3–4 days or more. |
Antihistamines | Antihistamines reduce the production of immune-system chemicals in allergic reactions, relieving itching, sneezing and a runny nose. |
Decongestants | Decongestants such as the blue 歐治鼻 quickly help clear breathing and are very suitable for emergencies. |
Keep the airway moist | Use a humidifier or warm towel on the nose in moderation to ease inflammation of the nasal lining. |
Clear mucus | Use steam to thin mucus so it's easier to clear. |
Improve your sleep environment | Keep indoor air circulating and use a humidifier to reduce congestion during sleep. |
Breathing exercises | Exercises such as deep breathing and qigong breathing improve nasal airflow. |
Keep the nose clean | Rinse the nose with saline to remove secretions and dirt that have built up inside. |
Improve your living environment | Reduce contact with allergens and keep your home clean. |
Adjust your diet | Appropriately increase your intake of nutrients that help boost immunity, such as vitamin C and zinc. |
Regular check-ups | People with long-term congestion are advised to have regular professional ENT check-ups to determine the cause and get an appropriate treatment plan. |
