The research involved analyzing breathing data from 52 participants over 24 hours. The findings showed that those with a normal sense of smell exhibited small inhalations, or “sniffs,” that were absent in individuals with anosmia—either congenital or acquired, such as after a COVID-19 infection. The study indicates that nearly one in four people experience anosmia, a statistic likely underestimated by health professionals.
A 2023 report found that over 60% of COVID-19 patients experienced a loss of smell. While 72% regained their olfactory senses, approximately 4% did not recover. However, there is emerging hope, as some individuals have regained their sense of smell even three years post-infection. Treatments like smell training and stellate ganglion blocks may aid in recovery.
Lead author Lior Gorodisky, a Ph.D. candidate at the Weizmann Institute of Science, emphasized the broader implications of these findings. “The differences in breathing patterns between those who can smell and those who cannot are significant. We can now identify lifelong anosmia through respiratory patterns,” he explained.
The study highlights the unconscious nature of the sniff response, which plays a crucial role in how we experience and interact with our environment. For example, the delightful aroma of a bakery can prompt a deeper breath, enriching our sensory experience. However, the absence of smell can diminish memories tied to specific scents, reducing joy in daily activities like eating and socializing.
Previous research has also linked anosmia to a range of negative outcomes, from emotional dullness to shorter lifespans, potentially due to the inability to detect hazardous odors, such as smoke. Valentina Parma, assistant director at the Monell Chemical Senses Center, noted the study’s significance, stating, “This is a first step in emphasizing the need to prioritize the sense of smell.”
Despite its profound impact, anosmia remains underdiagnosed. Health providers often overlook it, despite its connections to serious conditions like Alzheimer’s and Parkinson’s diseases. Otolaryngologist Dr. Jonathan Overdevest stressed the need for increased awareness and testing for anosmia, stating, “The loss of smell could be an early indicator of broader health issues.”
The study calls for further research into how olfactory dysfunction may influence other aspects of health. As Dr. Benjamin tenOever from NYU Langone Medical Center pointed out, “Smell is intricately linked to many cognitive functions. Understanding this connection is vital for improving overall health outcomes.”
As the world continues to grapple with the lasting effects of COVID-19, this research sheds light on the critical need to address olfactory health, paving the way for future studies and treatments that may enhance quality of life for those affected.
