The turbinates also go through a process which is known as the nasal cycle. This cycle is where one turbinate increases in size whilst the other decreases and then they swap over. This accounts for why people notice that they have a blocked nose on one side which then swaps to the other side.
This pattern happens when there is more blood flow to the structures inside the nose, such as the turbinates, which are the round masses that you may see if you look into the nostrils. Increased blood flow causes congestion in one nostril for about 3 to 6 hours before switching to the other side.
In many people, the nasal septum is off-center — or deviated — making one nasal passage smaller. When a deviated septum is severe, it can block one side of the nose and reduce airflow, causing difficulty breathing.
During the nasal cycle, unequal blood flow in the nostrils causes the tissue in one nostril to fill with blood and block that nostril, while the other remains open. Researchers believe 70–80% of adults have a regular nasal cycle.
When you've got a blocked nose, try sleeping on your back with your head elevated so gravity can then help to drain away congestion. Sleeping on your side can also help keep your airways open, so you can breathe more easily. If acid reflux is causing your blocked nose, sleeping on your left side is best.
It's common and usually clears up on its own within 2 to 3 weeks. But medicines can help if it's taking a long time to go away.
There's really nothing you can do to shut off the nasal cycle, says Dr. Roditi. It's likely that one nostril will always feel more stuffed up than the other when you're sick. Still, after about 90 minutes to 4 hours, your nose switches sides.
It is quite common for people to complain of having a blocked nose on one side. If this is caused by an infection or allergies, then it is quite common for the blocked nostril to switch sides. If caused by a deviated septum or obstruction, then the same nostril will always be affected.
When we have a cold, the blood vessels in the nose dilate as part of the body's immune response, and the nose also produces more mucus. Both of these changes cause congestion, but you'll feel more blocked in the nostril that's currently 'off duty'. The nostril with the full airflow might feel fine.
An untreated deviated septum can cause obstructive sleep apnea. When left untreated, sleep apnea can lead to high blood pressure, stroke, heart failure, heart attacks, diabetes, depression, worsening of ADHD and headaches.
According to Dr. Leann Poston of Invigor Medical, “Elevating your head before bed can increase drainage and decrease congestion.” That's why the best position to sleep with a stuffy nose is on your back with different types of pillows elevating your head and neck.
Both the swelling and extra mucus lead to nasal congestion. This is when the narrowed passages increase the effort of breathing through the nose. Clearing the mucus by blowing the nose should reduce this congestion somewhat. At the beginning of colds and for most of the time with hay fever, there's lots of runny mucus.
One of the main reasons why nasal congestion gets worse at night is because of gravity. When lying down, the blood vessels in your nasal passages dilate which leads to increased blood flow to the area. This causes the tissues to swell and become congested.
Blowing the nose can worsen the feeling of congestion due to pressure build-up within the nostrils, which may shoot up the mucus into the sinuses instead of ejection through the nose.
“Blowing your nose is useful, but if nothing is coming out, it generally means there's not a lot of mucus.” The three common culprits behind inflammation in your nose are infections, allergies, and nonallergic rhinitis, says Dr. Alexander.
Use a warm compress: applying a warm compress like a washcloth to your face and allowing it to sit for 10-15 minutes can also help break up the mucus and alleviate the pressure when you have a sinus infection.
If you have a severely deviated septum, your nose may look crooked from the front or sides. But for some people, their nose may look straight, and they could still have a deviated septum. The underside of your nose can be a better indicator of a deviated septum.
What is the difference between a broken nose and a deviated septum? While they are similar, a deviated septum and fractured nose are not the same things. A deviated septum refers to the deviation (or movement) of the wall that divides your two nasal passages.
