At first glance, it may seem offensive to someone to say that someone else has an “old smell.” There are also those who wonder: does this smell really exist? Yes, there are scientific studies indicating that wear odor does exist and it’s not something offensive or associated with poor hygiene — it may be related to a molecule produced in the skin. This smell can appear as early as 30 years old.
It’s an old topic, but it’s back in the social media spotlight thanks to radiologist Ina Mondragon’s TikTok video. “The smell of old people is present and can begin to appear from the age of 30,” the radiologist from Nicaragua says in the post. Next, he points out, this smell is not associated with poor hygiene and occurs from the age of 30 because that’s when the natural antioxidant capacity declines. “It’s a natural process for our body,” he asserts. A process associated with the non-renal molecule that is produced in the skin when fatty acids are naturally oxidized.
Scientific studies specifically point to the presence of a pungent odor. In one such work, it was concluded that, compared to people between the ages of 25 and 40, people aged 40 and over had higher levels of non-renal molecule 2 in their skin and sweat. In a 2012 article published in the journal Scientific American. The researchers pointed out that this chemical may be “a major cause of the deterioration of body odor that appears with age.”
And what is this smell? In the same post, he mentioned that there are people who associate this with the smell of cucumbers and stale beer, which is annoying to a lot of people. There are also people who say it smells like old books or even old people. This investigation has been published In the scientific journal Journal of Investigative Dermatology.
Another study, also from 2012, revealed that other humans were able to determine the age of other humans by differences in their body odor. In this work published in the scientific journal Plus oneIt was found that the participants were able to distinguish between three categories based on odors, one of which was the smell of the elderly. It was also found that the body odor of the older group (75 and 95 years old) was less intense and less irritating than the body odors of the young (20 to 30 years old) and middle-aged (45 to 55 years old). .
“Older people have an underarm odor that young people find completely neutral and not at all annoying,” says Johan Lundstrom, a scientist at the Monell Center in the US. in the current situation at the time of publication of the work. “These results were surprising given the popular perception that bad breath stinks.”
