Olfactory Training
In what is known as “classical olfactory training,” people inhale four intense odors twice a day. The approach has been reported to consistently improve scores in smell testing. Olfactory training appears to improve the nerve connections between the nose and the brain.
In the following method,
A. The training consists of smelling four different odors: rose, eucalyptus, lemon, and clove, twice a day and every day for three months.
Choose one odor and smell it for approximately 15 seconds, while trying to remember what it once smelled like.
Rest for about 10 seconds.
Smell the next odor for approximately 15 seconds.
Repeat until all 4 odors have been sampled.
B. After 3 months switch to a new set of odors: menthol, thyme, tangerine, and jasmine and train with them as described above.
C. After 3 months switch to another new set of odors: green tea, bergamot, rosemary, and gardenia and train with them again as described above.
