One of the side effects of COVID-19 includes loss of smell and taste. For some, this can take months.

One of the most striking symptoms of COVID-19 is the temporary loss of odor and taste. For a subset of people, these symptoms can last for months, generating great stress and anxiety, however something called “smell therapy” helps them cope.

Also known as olfactory recycling or olfactory formation, research suggests that it is an affordable, non-invasive, and convenient way to treat olfactory loss.

Odor therapy is simple: it involves exposing the person to strong odors, such as eucalyptus, rose, lemon and cloves, for a period of 15 to 20 seconds, twice a day. These scents are supposed to evoke the four main scents: floral, fruity, aromatic, and resinous.

In a study published in the journal Laryngoscopes, The researchers found that after a 12-week period, participants reported better odor recognition compared to those who did not follow odor tests.

“It’s important for you to understand that, for example, it’s a rose scent that you’re supposed to smell,” said otolaryngologist Dr. Raj Sindwani. he said Jo. “The idea is to try to think about the smell and look of roses by combining visual images with stimulating aroma in isolation.”

Despite the research, the way the olfactory system works is not fully understood. In a normally functioning system, odor particles in the air indicate the receptors in the paranasal sinuses, which then send a signal to the olfactory area of ​​the brain. Viral diseases can harm these receptors.

Odor therapy is supposed to involve the brain in the act of smelling and attracting neuroplasticity, helping it to grow, reorganize, and create new pathways and bonds related to smell.

Although most people who suffer from COVID-19 and lose their sense of smell recover it in a couple of weeks, this is not the case for everyone. For some, their smell returns slowly and may never fully recover. Odor therapy can help speed up the recovery process, providing these people with a sense of control.
