Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This hallucination 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.
Smell disorders can result in the inability to detect environmental dangers such as gas leaks, toxins, or smoke. In addition to safety, nutritional and eating habits can also be affected. There is a loss of appetite because of unpleasant flavor and fear of failing to recognize and consuming spoiled food.
Hyperosmia is an increased olfactory acuity (heightened sense of smell), usually caused by a lower threshold for odor. [1] This perceptual disorder arises when there is an abnormally increased signal at any point between the olfactory receptors and the olfactory cortex.
Example ORS behaviors include: repetitive showering and other grooming behaviors, [9] excessive tooth brushing, [9] or tongue scraping (a treatment for halitosis), repeated smelling of oneself to check for any odor, [5] over-frequent bathroom use, [1] attempts to mask the odor, [5] with excessive use of deodorants, perfumes, mouthwash, mint ...
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...

Past research has highlighted the importance of a male's scent to females, such that smell was rated significantly more important for women than men. Furthermore, smell and body odour were rated as the most important physical factor for females, compared to looks for males. [60] Further studies have aimed to understand these sex differences.
Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor.For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
