People with a poor sense of smell are 50% more likely to be hospitalized for pneumonia than those with a good sense of smell.
A simple smell test could help doctors to identify which patients in a vegetative state will recover. 100% of patients in a vegetative state who reacted to the sniff test went on to regain consciousness. 91% of those were still alive three years post-injury.
Damaged olfactory neurons as a result of air pollution may contribute to altered cerebrospinal fluid flow and turnover, acting as a potential mechanism for the development of neurodegenerative diseases.
Researchers have been able to map odor molecules based on how often they occur in nature with the help of mathematical modeling.
According to a new study, your sense of smell could be responsible for weight gain. Using mice, researchers noticed that those who lost their sense of smell also lost weight, while those mice with a super sense of smell gained more weight on a high fat diet than mice with a regular sense of smell. Findings suggest odor may play an important role in calorie burning processes; if you can't smell your food, you may burn it rather than store it.
