Has Covid-19 damaged your sense of smell? Smell training may help.
⋮
For the many Covid-19 patients who have lost all or some of their sense of smell, doctors recommend an olfactory version of physical therapy called smell training. Writing for the
New York Times, Christina Caron talks with multiple experts to demystify the (surprisingly tedious) process.
What is smell training?
According to Caron, a large proportion of people who contract Covid-19 report losing their sense of smell entirely or in part or experiencing parosmia, a disorder that causes previously normal odors to develop a new, often unpleasant aroma. In fact, at least one meta-analysis, published in September 2020, found that up to 77% of Covid-19 patients report some form of smell loss, she writes.

Sense of smell can be altered for 5 months or more after acute SARS-CoV-2 infection, Canadian researchers reported.
Nearly one in five healthcare workers who had a compromised sense of smell when they first were infected reported persistent olfactory changes 150 days later, said Johannes Frasnelli, MD, of the University of Quebec at Trois-Rivieres, and colleagues, in a preliminary report released in advance of the American Academy of Neurology annual meeting.
The findings are based on 813 Quebec healthcare workers who tested positive for SARS-CoV-and completed online questionnaires and home chemosensory tests an average of 5 months after diagnosis. Most participants (84%) were women.
