Wake up with a blocked nose every morningAllergy is the most common cause for people to wake up with a blocked nose, or nasal congestion. If air pollution such as allergens in your bedroom is being inhaled, they are likely to cause an over-reaction of the immune system. In this response, antibodies are produced and cause the symptoms of congestion because they make the tiny capillary blood vessels in the nose leak fluid.  Your nose feels blocked up, it is hard to breathe and you wake up with a blocked nose, and often a headache.

But why do you wake up with a blocked nose every morning?

You might wake up with a blocked nose because air pollution is present in your bedroom environment. Such pollution might come from indoor, or outdoor sources. In this article, we will explain how you can best tackle them so that you do not wake up with a blocked nose anymore.

House dust mite
One of the most common allergen to cause blocked noses is the dust mite allergen.  The droppings of the house dust mite contain potent allergens and, since the droppings are only a few microns in size they easily become airborne and are inhaled. The dust mites favourite locations are carpets, bedding and mattresses. Therefore, night time is prime time for dust mite allergen.  Exposure to the allergen - especially over a longer period of time -  will wake up with a blocked nose in the morning as a result.

To properly control dust mite allergens in your home, you should use effective allergy friendly cleaning products to naturally destroy dust mite allergens on contact. Your bedding should be washed regularly with an allergy laundry detergent and dried thoroughly (mites flourish in even slightly damp conditions). You might also consider making a fresh start by buying a new mattress, pillows, and duvet. Hard flooring, rather than carpet, in the bedroom, is a plus and it helps to damp dust regularly and keep clutter - which collects dust - to an absolute minimum.

Traffic pollution
Traffic pollution is a very common cause in people waking up with a blocked nose as it causes perennial rhinitis. The main components of traffic pollution are ground-level ozone, particulate matter, and nitrogen oxides.  These pollutants tend to have an irritant effect on the respiratory tract and can enter a bedroom through cracks in the windows and walls or directly through the window when ventilating. You have less control over outdoor pollution, but you can effectively control air pollution in your home with an effective air purifier. An effective, leakage free air cleaner fitted with a High-Efficiency Particulate Air (HEPA) filter will capture and retain all the particulate pollution including pollen, mould spores, dust mite allergens and more.

If you wake up with a blocked nose only in spring, summer or autumn, then it is likely you have hay fever (also known as seasonal allergic rhinitis). You may be allergic to pollen from trees, grass or weeds. Pollen is very light and travels over great distances. So if you leave bedroom windows open, pollen is likely to drift in. It is also carried on clothes and hair. A good tip is to keep outdoor clothes out of the bedroom, change clothes when you come in from outdoors and wash your hair to remove pollen.

If your bedroom is even slightly damp, it could be that mould spores are causing you to wake up with a blocked nose in the morning. Check the windows do not have any cracks or leaks, and treat any damp patches on the wall or ceiling with Allersearche's Allermold Mould Spray. If you have an en-suite bathroom, it is a good idea to keep the door closed at all times and to open a window after bathing or showering, to prevent your adjoining bedroom from becoming too damp.

When you wake up with a blocked nose, this can also be treated with antihistamines or with steroids, preferably in the form of nasal drops. However, nasal decongestant sprays are not a good idea because their use leads to 'rebound' nasal congestion – so you risk your blocked nose getting worse.  It is important to point out, however, that medication will only tell your immune system to look the other way.  To effectively treat your blocked nose in the long term, you have to limit the day to day exposure to the allergy triggers in your home.

Pet Dander
Pet dander is found in the sweat and saliva of dogs and cats, which is shed as tiny lightweight particles that travel readily around your house. If you let a pet into your bedroom, then you may well wake up with a blocked nose due to an allergic reaction triggered by the pet dander. But pet dander can even end up in your bedroom if your pet never goes in there. Moreover, animal dander persists for many months after an animal has left the premises. If you have recently moved and have no pets yet still find you wake up with a blocked nose in the morning, then it may be that the previous owner had a pet.

Among the non-allergic causes that might make you wake up with a blocked nose, are sinusitis, colds and flu, nasal polyps and a condition called vasomotor rhinitis.
