Causes of Nasal Congestion

Who hasn’t had a runny or blocked nose before? The tissues pile up around you and the thought of trying to cook dinner or read a bedtime story to your child with your nose dripping like a tap isn’t exactly what you had in mind for your evening.

So, let’s talk about your nose and what’s happening. Within your nose, you have the nasal airway and is surrounded by sinuses (air filled cavities), as well as blood vessels (veins and arteries).

A blocked nose, also known as nasal congestion, happens when the blood vessels in your nose become dilated or swollen due to irritation. What happens is that these vessels and tissues in the nose can swell and block the nose, causing that blocked, “bunged up” stuffy feeling, while nasal congestion may also result in a runny nose!1,2

Often nasal congestion can also come with sinus pain. Sinus pain can happen when changes in air pressure affect the sinuses and blood flow.1,2 That’s why you often get both a blocked nose and a sore face (sinus pain) when you have a cold or the flu.

Nasal Congestion Relief

As a busy parent you don’t have time to blow your nose every few minutes, or deal with feeling like your head is about to explode when you’re helping your kid do their homework.

To help relieve the symptoms of nasal congestion, try to keep your nasal passages and sinuses moist. Using a humidifier or vapouriser may help. Reducing the swelling of blood vessels and tissues in your sinuses can also help temporarily relieve nasal congestion. There are products available as either tablets, sprays or vapourisers that have ingredients designed to help open your sinuses and reduce swelling in the nose. These can offer temporary relief from a blocked nose and help reduce pain due to inflamed sinuses.1,3

So you can focus on the bedtime story, and not your nose, explore the DEMAZIN® range for relief to see what products are best to relieve your nasal congestion symptoms.
