What is Parosmia?

Parosmia is a condition where the normal perception of smells has changed. For many people affected by it, pleasant smells can become unpleasant and even overwhelming.¹

Parosmia has been shown to be one possible symptom from Covid-19. Many Covid-19 patients first experienced the loss of taste and smell, but most of them recover from this condition. However, new data from studies performed on post-covid patients suggests that Parosmia is an additional long-term symptom.¹

Many with parosmia struggle daily with “normal” smells like coffee, flowers, or food. The altered smell of these things have been reported to have changed so drastically that they are now perceived unpleasant. The altered smells can now be rotten eggs, garbage- or ammonia. Parosmia existed before Covid and can be caused by other things, such as respiratory infections, seizures or brain tumors. Even though Parosmia is not seen as an urgent symptom of Covid-19 in relation to symptoms like heart problems or respiratory illness, it is still problematic and causes suffering for those affected.²

How does parosmia affect people?

Smell is important to enjoy food and to reawaken memories and feelings. For example, the smell of your grandma’s perfume, Christmas Eve, or your pet.²

Smell is also one of the special senses that monitor our environment by sensing danger, to help us escape from dangerous situations.³

Parosmia can affect the quality of life of those affected in more ways than one. Parosmia has been shown to cause frustration, and in some cases anxiety depending on the severity.²

What can you do about parosmia?

Parosmia is often resolved on its own with time, but there are things you could do to help your sense of smell. One of them is Smell training, also called olfactory training. The training should include a schedule of sniffing a group of different scents, 20 seconds per scent, twice a day, for at least 3 months. Use the same scents for a longer period of time during the training.When choosing scents, try to include many different qualities such as fruity, spicy, flowery, and resinous. A tip is to choose scents that you used to enjoy or that used to bring back memories.4

Besides training, patients with Parosmia can also feel the need to address the unpleasant odors when they occur in their everyday life.

There are several ways to block odors around you, but one effective and discreet way is to use NOSA menthol plugs. The menthol fragrance blocks the unpleasant odor in your environment, and instead fills your nose with a refreshing menthol fragrance. Additionally, the little plug is easy to breathe through and is almost invisible to your environment.

NOSA has gotten positive feedback from several customers that suffer from Parosmia, stating that NOSA menthol plugs have helped them immensely.

Here are some of the reviews:

“I want to thank you for the incredible product. I’ve been suffering from Parosmia and needed something to help with everyday smells. You have greatly improved my quality of life. Thank you! <3” – Kendel, US

“I want to thank you greatly for the Odor Protection product. I am suffering from parosmia after my COVID infection last fall, and there are a ton of common smells that are very offensive to me. I recently purchased two 7x packages of the NOSA odor protection plugs, and they’ve really given me back a lot of freedom. I can just slip a pair in whenever there’s an unpleasant smell, and I can mostly continue with my day! So THANK YOU!” – Barrette, Canada
