Unveiling the science behind the 'senior scent' phenomenon
Older adults often emit a distinctive odour, which is mistakenly associated with poor hygiene. Scientists have discovered the true source of this scent.
Many elderly people emit an odour that can be described as musty or greasy. Contrary to common beliefs, this does not result from neglect of hygiene. Researchers have identified the chemical compound, 2-nonenal, as the main cause of this aroma. It is produced by the oxidation of fatty acids in the body. As we age, our skin becomes more susceptible to these processes, which intensifies the smell.
Why do older individuals emit a distinctive odour?
The team led by Dr. Shinichiro Haze demonstrated that 2-nonenal is responsible for the characteristic scent, which is not a sign of a lack of cleanliness in older adults. Because this compound does not dissolve in water, even frequent washing doesn't completely remove it - which is confirmed by research.
Dr. Haze also discovered that the scent of older individuals may have roots in genetic heritage. Ancestors used it to assess age or health status. Although today it's perceived negatively, it once played a very important informative role.
Not all elderly people smell the same
Research shows that not all elderly individuals emit this distinctive odour. Only half of the subjects had noticeable levels of 2-nonenal. Those who don't have it shouldn't worry, and those who do - also shouldn't feel ashamed.
Although it is not possible to completely eliminate the odour of seniors with standard hygiene methods, there are ways to reduce it. A healthy lifestyle plays a key role. Reducing stress, maintaining a healthy diet, engaging in regular physical activity, and avoiding stimulants such as cigarettes can help reduce the intensity of the odour.
It is also important to remember that the scent of older individuals, even though it is often perceived negatively, is part of our natural biology. It's not only a matter of physiology, but also a testament to evolutionary processes. Treating this odour as a normal aspect of aging can lead to, among other things, a better understanding of the needs of seniors.
