The science behind ‘old people smell’ and why showers aren’t enough

The so-called “old people smell” has been a topic of discussion on social media, with many people describing it as a faintly musty or greasy scent associated with older adults. While some may see this as a stigma, experts say that there is more science behind this phenomenon than meets the eye.

Dr. Dan Wesson, a professor at the University of Florida College of Medicine, explained that as we age, the skin undergoes significant changes that can contribute to changes in body odor. While sweat, bacteria, and dead skin are usually the culprits behind body odor in younger individuals, aging skin produces different compounds that can result in a more complex scent.

One key compound that emerges from aging skin is 2-nonenal, which has a greasy, cardboard-like odor. This compound is not easily washed off with regular hygiene practices, making managing this body odor more challenging. Wesson suggests taking a holistic approach by incorporating antioxidant-rich foods into your diet, staying hydrated, and using antioxidant skincare products to help combat this unique odor.

In addition to changes in skin composition, certain medications and hormonal fluctuations can also impact body odor. Medications for conditions such as high cholesterol, ADHD, or depression may affect how much we sweat, while declining estrogen levels in post-menopausal women can lead to changes in skin and scent.

However, it’s important to note that not all changes in body odor are normal. A sudden shift in body odor could be a red flag for an underlying health issue, such as cancer or dementia. If you or your loved ones notice a sudden change in body odor, it’s essential to consult with a doctor to rule out any potential health concerns.

Furthermore, some individuals may experience distorted senses of smell, such as parosmia or olfactory hallucinations, where unpleasant smells are perceived even when they are not present. It’s crucial to differentiate between real odors and changes in perception to address any concerns effectively.

By understanding the biology behind age-related odor and taking a proactive approach to health and skincare, managing this condition is possible. It’s essential to prioritize overall health and wellness to address any changes in body odor effectively.
