Olfactory fatigue
Olfactory fatigue, also known as odor fatigue or olfactory adaptation, is a phenomenon characterized by the temporary, normal inability to distinguish a particular odor after a prolonged exposure to that airborne compound.
Causes[edit | edit source]
Olfactory fatigue is caused by a temporary inability to distinguish certain odors after a prolonged exposure. This can occur for several reasons, including:
- Prolonged exposure to the same odor, which can cause the olfactory receptors in the nose to become temporarily desensitized.
- Certain medical conditions, such as sinusitis or upper respiratory infection, can also cause olfactory fatigue.
- Some medications, such as antibiotics or antihistamines, can also affect the sense of smell and lead to olfactory fatigue.
Symptoms[edit | edit source]
The primary symptom of olfactory fatigue is an inability to distinguish certain odors. This can be particularly noticeable when the individual is in a situation where they are continuously exposed to the same odor. Other symptoms can include a reduced ability to taste foods, as the sense of smell is closely linked to the sense of taste.
Treatment[edit | edit source]
Treatment for olfactory fatigue often involves removing the source of the odor, if possible. If the condition is caused by a medical condition or medication, treating the underlying cause can often alleviate the symptoms. In some cases, a doctor may recommend olfactory training, which involves regularly smelling a variety of different odors to help retrain the olfactory receptors.
