'Sniffing 4 kinds of aromas twice a day' is effective for regaining the sense of smell lost in the new corona.
'Olfactory disorder' has been reported as one of the initial symptoms of the new coronavirus infection (COVID-19). Even after recovering from COVID-19, it is said that it takes a very long time for some people to regain their lost sense of smell. It has been reported that aroma rehabilitation is effective for such COVID-19-derived olfactory disorders.

Doctors Identify The Best Treatment For COVID-19 Smell Loss, And It's Not Steroids

The report was made by a research team consisting of doctors from multiple countries such as Belgium, the United Kingdom, Turkey, Denmark, Canada and Switzerland. 'The high proportion of patients who experience the mental or physical strain caused by the loss of olfaction creates an unprecedented demand for the treatment of olfactory disorders,' the research team said.
Loss of smell and taste is said to be a symptom that can predict infection with the new coronavirus with high probability. The mechanism by which COVID-19 causes the loss of olfaction is unknown at the time of writing the article, but one theory is that 'the function of the olfactory nerve may be inhibited by damage to the supporting cells of the olfactory cells around the nerve.' It has been pointed out.

Corticosteroids (corticosteroids) may be prescribed for COVID-induced olfactory dysfunction. However, the research team decided to prescribe corticosteroids because 'the evidence supporting the usefulness of corticosteroids is weak,' 'the spontaneous recovery rate of olfactory dysfunction is slow,' and 'corticosteroids have relatively strong side effects.' He pointed out that he needs to be careful.
To treat this olfactory disorder, the research team recommends aroma-based olfactory rehabilitation.
In a study of 1363 COVID-19 patients complaining of olfactory dysfunction, published in January 2021, 95% of patients who underwent olfactory rehabilitation to smell aroma twice daily regained olfaction six months later. It has been reported. The aromas used were at least four types: cloves, roses, lemons, and eucalyptus.
It seems that rehabilitation needs to be done for several months in some cases, but it can be expected to recover from olfactory dysfunction without side effects. The research team said, 'Focus on familiar scents such as perfume, lemon zest, vanilla, coffee, and look back on your memories while sniffing them.' 'For best results, smell every 12 weeks. It needs to be changed. '
'Olfactory rehabilitation can be expected as a cheap, simple and side-effect-free treatment for olfactory disorders, including COVID-19,' said Carl Philpott of the University of East Anglia, one of the research teams. Aims to support neuroplastic recovery, the ability of the brain to self-repair to compensate for changes and injuries. '
