- Olfactory or smell training may help restore a lost sense of smell particularly after a viral upper respiratory infection or head trauma where no physical nasal obstruction is present. Olfactory training is analogous to physical therapy used to help restore limb movement after a stroke or ear training for singers and musicians.
