“Old People Smell” is a Real Phenomenon—Here is What Causes it and How to Prevent it
“Old people smell,” often described as musty and mildly sweet, isn’t just a stereotype but a scientific phenomenon that occurs as people age, which can be addressed through certain helpful practices.
What Causes That “Old People Smell”?
Known colloquially as “old people smell,” this aroma stems primarily from the compound 2-nonenal. This compound emerges from the breakdown of fatty acids in the skin and tends to accumulate as we grow older (especially after the age of 40).
Your Body’s Chemical Changes with Age
The process behind the production of nonenal, which is often associated with the characteristic “old people smell,” is thought to be linked to hormonal imbalances that occur with aging. As we age, the balance of hormones shifts, leading to increased production of lipid acid in the skin.
Concurrently, the natural antioxidant defenses in our skin diminish, allowing more lipid acid to oxidize, which then forms nonenal.
Why Do Aging Bodies Smell Differently?
The exact reasons behind these biological changes remain largely enigmatic. However, the presence of nonenal becomes more noticeable in environments like senior living communities where many older individuals reside, amplifying the collective scent.
Age-Related Scents in Nature
Interestingly, this phenomenon isn’t confined to humans alone—it’s a pattern seen across several species, suggesting a biological role, perhaps in signaling age through scent.
The Secrets of 2-Nonenal
The transformation in body odor as we age, particularly attributed to the compound 2-nonenal, raises intriguing questions about its origins and purpose. While the exact reasons for this change remain a topic of research, the prevailing theory among scientists suggests an evolutionary function.
Newborns’ Unique Scent
For newborns, their distinctive fresh scent sets the stage, gradually morphing through adolescence, which is particularly evident in the sharp turn in aroma during the teen years among boys.
Distinctive Smells and Survival
These unique smells are not random but are thought to play critical roles in the survival and propagation of humans. For instance, the delightful scent of babies is believed to enhance maternal bonding—crucial for a newborn’s survival.
Beyond 2-Nonenal
Research highlights that while 2-nonenal is a key player, the overall scent change in elderly people involves more than only this compound.
The interactions between gland secretions and skin bacteria, along with the types of bacteria present, can also influence how someone smells as they age.
Myths About Aging Scents
This aroma is not necessarily indicative of poor hygiene—it’s a natural part of the aging process and can even be detected in impeccably clean environments like well-maintained senior residences.
Solutions for Aging Scents
With the identification of 2-nonenal, a significant factor in the change of body odor as people age, numerous personal care companies, particularly in Japan, have developed products aimed at masking this specific scent. However, research indicates that these products may not effectively target 2-nonenal itself.
How Society Actually Views the Smell of Old Age?
Interestingly, societal reactions to the scent associated with older individuals tend to be more accepting than often assumed. A notable study conducted in 2012 revealed that people generally find the odors of older individuals to be less intense and less unpleasant compared to those of younger age groups.
Scents Across Age Groups
This study involved 44 participants divided into three age groups—20 to 30, 45 to 55, and 75 to 90—who wore shirts with underarm pads designed to capture body odor over five days.
They avoided spicy foods to maintain the natural scent of their body odor.
A Noticeable (But Not a Bad) Smell
At the study’s conclusion, the underarm pads were analyzed by having other individuals smell them and guess the age and sex of the wearer. The results showed that while the scents of young and middle-aged individuals were similar and harder to distinguish, odors from the oldest group were distinct yet not necessarily off-putting.
These findings suggest that the unique smell attributed to older adults, though noticeable, is generally not viewed negatively.
How to Manage the Inevitable “Old People Smell”?
Despite its inevitability, there are strategies to manage and reduce the presence of this scent, ensuring comfort without stigma. This isn’t about masking who we are but understanding and adapting to the natural shifts that come with the passage of time.
Quit Smoking
Minimizing tobacco consumption is key in curtailing the evolution of the scent commonly referred to as the “old people smell.”
Tobacco affects the smoker’s scent and also embeds a lingering odor in environments and fabrics, exacerbating the aging smell that many find unpleasant.
Use Smell-Reducing Laundry Products
Incorporating detergrips and refreshers with special ingredients that break down the culprits behind the aging odors into regular laundry routines can be a game-changer.
Products such as detergents enhanced with odor-neutralizing properties and fabric sprays aimed specifically at odorous compounds are effective tools in maintaining a fresh scent and minimizing age-related body odors.
Wear Breathable Fabrics
Choosing the right materials for clothing can also play a significant role in managing nonenal odor. Opt for garments made from breathable fabrics like cotton or linen to allow better air circulation, which helps prevent excessive moisture and sweat on the skin.
Incorporating detergent additives designed to tackle grease and stains can further ensure that clothing remains fresh and less likely to harbor odors.
Keep Your Bed Clean
Maintaining cleanliness in bedding is also essential.
Regular laundering of sheets in hot water, airing out bedding between uses, and ensuring frequent changes can help mitigate the accumulation of odors.
Shower Frequently
Regular bathing is essential for managing body odors, and adopting the right techniques can enhance the effectiveness of your routine. Dermatologists advise showering in lukewarm or slightly warm water to protect skin integrity.
Additionally, using antibacterial soap can help in reducing the presence of bacteria on the skin that contributes to unpleasant smells. Regular shaving of body hair can also aid in maintaining cleanliness and reducing odor retention.
Exercise More Often
Engaging in regular physical activity is good for overall health and also plays a significant role in maintaining skin vitality. Improved blood flow from consistent exercise boosts body functions and skin health, potentially reducing the buildup of odors.
Regular sweating can help flush out toxins from the body, aiding in decreasing the presence of substances that contribute to specific aging-related odors like nonenal.
Stay Hydrated
Hydration is essential for preserving skin health and overall vitality. Drinking ample water helps flush out toxins that could enhance the presence of nonenal.
Consuming a diet rich in antioxidants, such as spinach, kale, bell peppers, and berries, supports the body in combating oxidative stress.
Keep Air Moving
To minimize the impact of nonenal odor, regular ventilation is key. Keeping living spaces open to air flow can significantly reduce the buildup of this scent, particularly in warmer, stuffier environments.
Relax
Employing relaxation techniques such as yoga, tai chi, meditation, and deep breathing can effectively reduce stress levels. These practices manage cortisol, a stress hormone, which can influence body functions including how odors are generated.
Socialize
Cultivating a robust social network and engaging in enjoyable activities like painting or gardening can provide significant stress relief, fostering a healthier body chemistry and reducing the potential for unpleasant body odors.
