Why Do I Wake Up With A Morning Sinus Or Blocked Nose?
Many of us have at some point woken up in the morning with a runny or blocked nose, and constant sneezing. Fortunately for some of us, these episodes can go away moments after waking up. However, for others, they can last throughout the day. If you do wake up with a runny nose or blocked nose, and you don’t have the flu, you might be dealing with allergic rhinitis or an allergic reaction to one or more allergens in your home1.
Before you conclude that you have a medical condition stemming from these symptoms, eliminate this list of common particles2 that are present in most bedrooms.
Most common reasons for allergy in bedrooms
Dust is one of the most common and most overlooked allergens. Most homes have dust mites that create dust regularly. However, most people notice it only when the particles accumulate on a plain surface.
Pollen is a common allergen even in countries like Singapore where humid conditions last all-year long. These particles usually enter your home from your air conditioning system or open windows. If your home employs a central air conditioner, you may notice these allergy symptoms even if you clean your home regularly. Pollen counts are highest in the morning, and therefore, you may see an increase in your morning sinus.
Having a furry friend with you at home can cause you to experience an allergic reaction. Some of the symptoms include a runny nose, and itchy or watery eyes. It would be good to note that this type of allergy is not caused by the fur itself, but rather the proteins found in the animal dander, saliva or urine. These allergy-causing particles usually stick onto pet fur, exposing us to allergens when we touch them. Additionally, they are light in weight and can be easily transported in the air, and onto your clothes and hair.
Pollens on pets
If you own a pet that is regularly exposed to the outdoor air, there is a chance that they may be carrying pollen. In such situations, even an air purifier won’t be able to remove these pollen allergens. If your pet often cuddles with you or sleeps in the same room, your morning sinus may be exacerbated.
Mold allergies are triggered by microscopic mold spores that float in the air, much like pollen. Indoor mold usually releases spores throughout the year and can be mostly found in damp areas of the home. These include bathrooms, laundry rooms, refrigerator and windowsills. In a country like Singapore which experiences humid conditions all-year round along with rainfalls, mold will be able to thrive easily. Morning sinus caused by mold allergies can be more rampant during the monsoon seasons too.
Frequent use of candles, air freshers or strong perfumes can introduce chemicals and irritants to your home. You may be sensitive to these irritants that accumulate in the air, triggering allergy symptoms like sneezing. Unlike tree pollen or dander, perfumes and scents are not considered allergens, but irritants.
What to do with persistent morning sinus
If you experience allergy symptoms in the morning like runny, itchy nose or sneezing constantly, an antihistamine like Clarityn® helps to relieve these symptoms. For blocked sinuses, oral decongestants such as Clarityn-D®* can help clear a stuffy nose4 so that you can wake up and embrace each brand new day.
