Today it is recognized as one of the indisputable symptoms of the coronavirus and also as one of the main sequelae among those who have experienced the disease.
Anosmia, or loss of smell, is not a serious consequence, but it is very uncomfortable and sometimes dangerous, since it can prevent us from recognizing when a food is out of date, or when we have a gas leak at home, among many other things.
And as if that were not enough, in some cases the recovery of the sense of smell begins to be almost worse, and what in medicine is known as ‘parosmia’, which is that all smells become almost nauseating.
Hate coffee because it smells like manure, or the favorite cologne that now looks like sewer water … or there are even those who say that their loved ones have gone to have a repulsive smell, which makes them suffer.
And so we meet thousands and thousands of people in the world trying to regain their sense of smell.
As many as one in five people still do not regain their sense of smell months after recovering from illness.
Medications can have side effects
The treatment that until now the doctors were applying are the medicines known as corticosteroids, which reduce inflammation in the body and are already used to treat conditions such as asthma.
But some specialists assure that there is little scientific evidence that these treatments are effective and, on the contrary, they have the risk of side effects potentials such as fluid retention, increased blood pressure, and even problems with mood swings.
As Professor Carl Philpott of the University of East Anglia Norwich School of Medicine says, “There is very little data to suggest that corticosteroids will remedy loss of smell.”
Workout 2 times a day
So in the search for a solution with less risk and that can help the many people affected by this ailment, a group of scientists recommends a olfactory training that can give good results, but without risks and at little cost.
It is a cheap and simple process that involves sniffing out different smells over a period of months to train the brain to recognize different smells again.
The training has been proposed by a team of researchers in an article published in the journal InternationalForum of Allergy & Rhinology.
You have to do it 2 times a day for several months, and it is so easy that it consists of smelling four things that have a distinctly different smell and at the same time easily identifiable and familiar to each person.
For example, we spend some time in the morning sniffing with deep breaths one after another and alternating, one orange, a few cloves of garlic, a few coffee beans and mint. And at night we repeat the operation.
According to the scientific article, research shows that 90% of people fully regain their sense of smell after six months.
As the researchers say, the goal of this training is a helps recovery based on neuroplasticityThat is, in the brain’s ability to reorganize itself to compensate for a change or injury. ‘
Fortunately, most people who experience loss of smell as a result of Covid-19 will regain their sense of smell spontaneously.
But we must not forget that, according to a study by the Pennsylvania State University, between 44% and 77% of Covid patients experienced a complete loss of smell during the acute stage of their disease. And one in five kept it for months. And that’s millions of people.
