**New Study Shows Sweet Fragrance Improves Memory in Humans**
By TeeJay Small | Published 5 mins ago
Scientists have made a groundbreaking discovery in olfactory research, finding that a specific smell can significantly improve and repair memory in human beings. The study, conducted by the UCI Center for the Neurobiology of Learning & Memory and supported by Procter and Gamble, utilized a sweet fragrance that was wafted through the bedrooms of older adults over several months. The results were astonishing, with participants experiencing a staggering 226 percent increase in cognitive capacity.
For adults at risk of developing dementia, this discovery could have massive implications as it provides non-invasive techniques for strengthening memory. It has long been theorized that smells can impact memory due to the emotions associated with certain scents. In fact, some companies have already capitalized on this concept by selling candles with scents that evoke memories of specific locations for homesick travelers.
The connection between smell and memory has not only been observed in scientific studies but has even been referenced in popular culture. In the hit AMC series “Breaking Bad,” the main character, Walter White, explains how olfactory sensors connect to the emotional center of the brain, the hippocampus, to his business partner Gustavo Fring.
The study implemented the sweet fragrance through diffusers during the participants’ sleep, resulting in improved memory and better sleep quality. Interestingly, there is emerging evidence linking smell loss due to complications from COVID-19 with memory issues and cognitive decline, further highlighting the importance of scent in memory function.
Previous studies have already shown that exposing patients with moderate signs of dementia to various smells throughout the day can boost memory, language skills, and alleviate depression. This suggests that daily activities such as cooking, cleaning, and spending time outdoors can enhance receptors in the brain by exposing the nose to different odors.
While the study does not specifically identify which smells have the best impact on memory, further research is expected to provide more information on this topic. The ultimate goal is to develop a non-invasive treatment or even a cure for dementia and Alzheimer’s.
Unlike other senses, such as vision and hearing, there are currently few options available to assist with age-related declines in the sense of smell. Scientists conducting these studies hope to change that and are looking forward to a future where medicinal smells could be readily available in drug stores nationwide. With the promising results connecting smell and memory, it is hoped that greater funds and resources will be invested in this field to advance our understanding and potentially offer effective treatments in the near future.
