Olfactory training also may work for age-related smell issues, says Edward McCoul, MD, an otolaryngologist with Ochsner Medical Center in New Orleans who led the study analysis. “It’s hard to think of a treatment that is lower risk and frankly lower cost,” he says. But the technique has been shown to be less helpful for smell loss due to head trauma and Parkinson’s disease.
A number of medical centers offer OT, but you can also try it at home: Set aside a few minutes each morning and evening and use at least four essential oils (eucalyptus, rose, lemon, and clove have often been studied; search “aromatherapy” to buy online) or try other strong scents, such as coffee or a favorite shampoo. “Smells are tied to memories and other parts of the central nervous system,” McCoul says. “There may be some benefit for recovery if you use [scents] that are important to you.” Hold the scent about an inch from your nose and take short, gentle sniffs. As you do, focus on memories related to the aroma, says Pamela Dalton, PhD, an olfactory scientist at the Monell Chemical Senses Center in Philadelphia. Repeat two to three times, and rest a few minutes between scents.
Be patient: You’ll need to train for weeks or months to see results, McCoul says. In the 2020 analysis, the regimens tested lasted from three to 14 months.
