Revealed: The true source of the "elderly smell" phenomenon
Older individuals often emit a specific odor that is mistakenly associated with poor hygiene. Scientists have discovered the true source of this scent.
Many elderly people emit an odor that can be described as musty or greasy. Contrary to popular belief, this does not result from neglecting hygiene. Researchers have identified the chemical compound 2-nonenal as the main cause of this aroma. It is produced through the oxidation of fatty acids in the body. As the skin becomes more susceptible to these processes with age, the odor intensifies.
Why do older people emit a specific odor?
A team led by Dr. Shinichiro Haze demonstrated that 2-nonenal is responsible for this characteristic aroma, which is not a sign of uncleanliness in older adults. Since this compound is not water-soluble, even frequent washing does not completely remove it, as confirmed by research.
Dr. Haze also discovered that the odor of older individuals may have roots in genetic heritage. Ancestors may have used it to assess age or health status. Although it is now viewed negatively, it once served a very important informative function.
Not all elderly people smell the same
Research shows that not all older individuals emit this specific odor. Only half of those studied had noticeable levels of 2-nonenal. Those who do not have it need not worry, and those who do should also have no reason to be ashamed.
While the scent of seniors cannot be completely eliminated with standard hygiene methods, there are ways to reduce it. A healthy lifestyle plays a crucial role. Reducing stress, maintaining a healthy diet, regular physical activity, and avoiding stimulants such as cigarettes can help reduce the intensity of the odor.
It is also important to remember that the smell of older people, although often perceived negatively, is part of our natural biology. It is not only a matter of physiology but also evidence of evolutionary processes. Treating this scent as a normal aspect of aging can lead, among other things, to a better understanding of the needs of seniors.
