It's not safe to use VVR inside or around your nose. If you do, it could be absorbed into your body through the mucus membranes lining your nostrils. VVR contains camphor, which can have toxic effects inside your body.
For example, place your index fingers on both sides of your nose where the nose and cheek meet (with one finger on each side), and apply moderate pressure for 2 to 3 minutes. You can also use your index fingers to apply pressure on the bridge of your nose, right between your eyebrows; hold for 2 to 3 minutes.
In fact, putting Vicks VapoRub directly under the nose, as opposed to rubbing it on the chest, may actually make it harder to breathe, according to results from a study published in the journal Chest. In children under age 2, this could result in an increase in mucus and congestion.
When the vapour from Vicks vaporub is breathed in, the ingredients can help relieve a blocked nose. They also have mild cooling effects that can soothe irritation in the lining of the nose, thereby easing breathing and relieving cough.
But rest assured: Even if you have a stuffy nose and can't breathe through your nostrils, you almost certainly won't die in your sleep. While it may make your sinus issues worse, you will be able to breathe through your mouth.
It's down to what's known as the 'nasal cycle'. We might not realise it, but our bodies deliberately direct the airflow more through one nostril than the other, switching between nostrils every few hours.
How Long Does Nasal Congestion Last? If your nasal congestion is from a cold or flu, it will likely last as long your cold or flu (anywhere from five to 10 days) or even longer. If your nasal congestion is the result of allergies, it may last longer, depending on your exposure to that particular allergen.
It works because holding your breath can encourage the nasal passages to widen. You should try to breathe through your nose rather than your mouth to prevent the blockage from returning. Mouth breathing can increase mucus production and trigger constriction of the airways, which can make a blocked nose worse.
Nighttime congestion can be caused by excess mucus, swelling of the mucous membranes, or a combination of the two. Lying down for bed often makes it worse. Health conditions that contribute to a stuffy nose at night include acid reflux, indoor allergies, and pregnancy.
But it's important to pay attention to how you breathe. In general, it's healthier to breathe through your nose instead of your mouth. That's because nose breathing is more natural and helps your body effectively use the air you inhale.
Where does all the snot come from when you have a cold?
When you have a cold, your nose and sinuses are more vulnerable to a bacterial infection. A cold virus can trigger the body to release histamine, a chemical that inflames your nasal membranes and causes them to produce a lot of mucus.
If you're sleeping a lot when you have a cold, flu, or fever, it's because your body needs the rest. Sleeping more than usual is helping your body build up its immune system and fight off your illness.
There's no way to cure a cold—or sweat it out. Breathing in warm, moist air can help alleviate cold symptoms, like congestion. Light exercise can increase blood flow, which also might help with congestion.
At night, there is less cortisol in your blood. As a result, your white blood cells readily detect and fight infections in your body at this time, provoking the symptoms of the infection to surface, such as fever, congestion, chills, or sweating. Therefore, you feel sicker during the night.
