Odor perception is a complex process involving the central nervous system and can evoke psychological and physiological responses. Because the olfactory signal terminates in or near the amygdala, odors are strongly linked to memories and can evoke emotions. The amygdala participates in the hedonic or emotional processing of olfactory stimuli. [49]
[1] The phobia generally occurs in chronic migraine sufferers who may have odor triggered migraines. [2] [3] Such migraines are most frequently triggered by foul odors, but the hypersensitivity may extend to all odors. One study found as many as 25% of migraine sufferers had some degree of osmophobia. [4]
In one review, 85% of reported cases had traumatic, smell-related experiences, and 17% of cases had stress factors unrelated to smell. [2] Reported smell-related experiences usually revolve around family members, friends, co-workers, peers or other people making comments about an odor from the person, which causes embarrassment and shame.

Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
When hosting a dinner party, lingering odors from long hours of cooking in the kitchen can be an issue. Cooking odors from fish, onion, garlic, burnt foods and fried foods can last especially long.

Approaches to improve bad breath may include physical or chemical means to decrease bacteria in the mouth, products to mask the smell, or chemicals to alter the odour creating molecules. [1] Many different interventions have been suggested and trialed such as toothpastes, mouthwashes, lasers, tongue scraping, and mouth rinses. [ 28 ]
