What Causes the So-Called “Old Person Smell” – and Simple Ways to Manage It
As we age, our bodies naturally change. Most people expect shifts in energy, skin texture, or metabolism—but fewer realize that scent can change too.
What’s often referred to as the “old person smell” isn’t a sign of poor hygiene or neglect. In fact, it’s a normal biological process that scientists understand quite well.
Why body scent changes with age
Over time, the skin becomes thinner and renews itself more slowly. Hormonal changes also affect how oils are produced.
One specific compound, known as 2-nonenal, increases with age when skin oils oxidize. When this compound interacts with natural skin bacteria, it can create a mild, sometimes musty or grassy scent.
Importantly, this happens regardless of cleanliness. Many older adults shower regularly and maintain excellent hygiene, yet still notice changes.
It’s not about doing something wrong; it’s about the body working differently.
The good news: small habits make a big difference
Managing age-related body odor doesn’t require harsh products or drastic routines. In fact, gentler care often works better. Here are a few everyday bathroom habits that can unintentionally make odor more noticeable—and how to adjust them.
Over-cleansing sensitive areas
Using scented soaps or wipes in intimate areas can disrupt the skin’s natural balance, sometimes making odors stronger rather than fresher.
What helps: warm water or a mild, fragrance-free cleanser used externally only, followed by thorough drying.
Reusing damp towels
Towels trap moisture, skin cells, and bacteria—especially in humid bathrooms.
What helps: wash towels regularly and let them dry completely between uses.
Skipping foot care
Feet are enclosed for hours and naturally sweat more.
What helps: wash daily, dry well between toes, change socks daily, and exfoliate weekly.
Flushing with the lid open
This can release microscopic particles into the air that settle on nearby surfaces.
What helps: close the lid before flushing and clean bathroom surfaces often.
Sleeping in worn underwear
Even if you don’t feel sweaty, fabric holds moisture and bacteria.
What helps: change into fresh underwear before bed or choose breathable fabrics.
Ignoring the bathroom trash bin
Used tissues and hygiene products can slowly create lingering odors.
What helps: empty it frequently and clean it weekly.
Wearing an unwashed bathrobe
Bathrobes absorb moisture just like towels.
What helps: wash weekly and allow them to air-dry fully.
Not rinsing underarms well after shaving
Residue from hair, deodorant, and dead skin can linger.
What helps: rinse thoroughly and let skin dry before applying deodorant.
It’s not unpleasant—bias plays a role
Interestingly, research suggests that age-related body scent is not widely perceived as offensive.
A 2012 study found that people were generally neutral or unbothered by it.
What influenced reactions most was knowing the scent came from an older person—highlighting how age bias shapes perception more than the smell itself.
A natural part of aging, not something to fear
Aging comes with changes, and scent is just one of them. With a few mindful adjustments and a gentler approach to self-care, most people can feel comfortable and confident, without trying to “fight” nature.
Growing older isn’t about losing freshness; it’s about learning how your body evolves and caring for it with understanding rather than judgment.
