Olfactory training is helpful for all with persistent COVID-19–related parosmia or hyposmia because this therapy has low cost and negligible adverse effects. Anosmia can also greatly decrease your quality of life, leading to depression. Add ½ teaspoon of salt and ½ teaspoon of baking soda to the water.

Parosmia can usually be traced back to an infection or brain trauma. When parosmia is triggered by medication, chemical exposure, or smoking, it usually subsides once the trigger is removed. You’ll need to speak with your doctor to find out the best treatment for you.

These all have the ability to change your perception of smell. Loss of smell can occur due to problems in the nose, brain, or nervous system. The impairment is usually a distorted sense of smell. Age, gender, and how good your sense of smell was to begin with all play a part in the long-term prognosis for people with parosmia. Phototherapy treatment results in DNA damage but does not appear to predispose to carcinogenesis.
As we previously mentioned, it can be one specific smell or the smell of everything that triggers the disorder. For example, a piece of toast may smell like rotting meat to the person suffering from parosmia. In addition to the transformation of smells, due to the very close connection between your senses of smell and taste, the latter can also be altered. So when eating food, the food might also taste terrible.

In one case study from 2006, this side effect led to weight loss and malnutrition due to food aversions connected to parosmia. If you continue to experience parosmia and it’s impacting your appetite and weight, you may consider olfactory training therapy. Also known as “smell training,” this type of therapy involves intentionally sniffing four different types of odors up to 15 seconds at a time each. The process is completed twice daily for several months. From the vast spectrum of symptoms that can be present in a COVID-19 patient, loss of smell and taste has now been included as a part of the diagnostic criteria of COVID-19. A COVID-19 patient who is otherwise minimally symptomatic or asymptomatic can have a loss of sense of smell and taste as the only symptom.
For example, something that once smelled pleasant may smell bad or rotten to a person with parosmia. Additionally, some people may also experience parosmia after having COVID-19. Parosmia is a smell disorder where odors become distorted. At the same time, parosmia as part of your COVID-19 recovery can be difficult, as it may change your enjoyment of and desire for certain foods.
Why COVID-19 vaccines don’t cause parosmia
These nerves help to identify smells, and can be negatively affected by bacterial or viral respiratory infections, like sinusitis, the common cold or COVID-19. If loss of smell and taste was one of your acute COVID-19 symptoms, you may be at increased risk of parosmia. In many cases, people with parosmia also experienced loss of smell and taste while they were sick with COVID-19. The symptoms of parosmia are fairly easy to understand. The disorder causes certai to smell different, usually terribly.
A May 2021 study found that participants reported parosmia that lasted anywhere between 9 days and 6 months. Such cases point to parosmia as a possible long-term complication of COVID-19. One cause of parosmia symptoms is olfactory damage from a cold or virus. Upper respiratory infections can damage the olfactory neurons.
Although it can help with recovering your sense of smell, more scientific studies are needed to prove the efficacy of this therapy. Although it is rare, parosmia can emerge about 1 to 2 months after the initial infection of the coronavirus, and it can persist for 8 or more months. Many people experience constant foul odors, like rotten meat, which can affect your quality of life. This abnormality occurs due to damage to olfactory nerves that send signals to the brain.
They’ll give you a physical exam to check for a virus, allergies, or sinus infection. Smell training may be most effective if you work on the same four odors each day, rather than alternating. It’s also recommended that you concentrate on the scent fully, giving it your full attention, for the entire 20 seconds.

However, it may take weeks or months to see an improvement. The same study found that half of these people reported a sudden onset of parosmia, while the other half reported a gradual onset. Researchers are still trying to determine how common parosmia after COVID-19 actually is. One June 2021 survey found that out of the 1,299 survey respondents, 140 of them (10.8 percent) reported having parosmia after COVID-19. One study involving 268 people with parosmia after COVID-19 found that 70.1 percent of them were age 30 or younger, and 73.5 percent were female. Less often, parosmia is caused by a sinus polyp, a brain tumor, or is an early sign of certain neurological conditions.
More than 190 million people have developed COVID-19. Many other people have likely had the viral infection but never received a confirmed test result. Eat foods that are cold or at room temperature, as heat can enhance scents. It’s estimated that humans have 350 types of smell receptors. Additionally, our brain identifies individual odors based off of a combination of different signals from these receptors. Generally speaking, parosmia after COVID-19 can gradually fade with time.
