Many people notice a peculiar odor when they visit an elderly person’s home or are around older adults. This scent, often described as “old person smell,” is real, even though the elderly themselves might not notice it. Let’s explore the reasons behind this phenomenon and what can be done about it.

”Old Person Smell” Is Real

Research indicates that as we age, our bodies emit certain volatile compounds, one of which is 2-nonenal. This compound is only detectable on the skin of individuals over 40 and smells like stale clothing or musty grass. The odor tends to intensify with age due to the increased production of omega-7 unsaturated fatty acids, which break down into smelly 2-nonenal.

In addition to 2-nonenal, dietary habits, lifestyle choices, and chronic diseases can also contribute to a stronger body odor in older adults. For instance, diabetes can produce a rotting apple scent due to ketones, and chronic kidney disease can cause a fishy odor from nitrogenous waste products. Dental issues, such as cavities or gum disease, can result in a foul-smelling breath due to bacterial overgrowth.

Even healthy individuals who smoke, drink excessively, or have poor hygiene can develop strong body odors. This explains why some younger people also have noticeable body smells.

Why Can’t Elderly People Smell Themselves?

It’s not that elderly people are unaware of their odor; they genuinely might not smell it. This is due to a higher “odor threshold” in older adults, meaning they need a stronger concentration of a scent to detect it. Studies show that seniors’ odor thresholds are 2-15 times higher than those of younger people. Aging naturally dulls the sense of smell, and conditions like Alzheimer’s and Parkinson’s can exacerbate this loss.

Moreover, our sense of smell adapts to persistent odors. So, even if older individuals initially notice the smell, prolonged exposure can desensitize them to it.

Can “Old Person Smell” Be Eliminated?

While it may not be possible to completely eliminate age-related odors, there are ways to minimize them:

1. Maintain Hygiene

• Encourage regular bathing (at least every two days) and changing clothes frequently. Fresh clothes should be worn immediately after bathing.
• Ensure proper ventilation in living spaces by opening windows regularly.

2. Encourage Physical Activity

Regular exercise helps reduce the risk of chronic diseases and maintains healthy organ function, which can reduce body odor. Seniors should aim for at least 150 minutes of moderate-intensity aerobic activity (like brisk walking or gardening) or 75 minutes of vigorous-intensity activity (like running or hiking) per week.

3. Healthy Lifestyle Choices

Managing weight is crucial as obesity increases the risk of diabetes, which can contribute to body odor. A balanced diet and avoiding high-calorie fried foods are important. Promoting good lifestyle habits can significantly impact overall health and body scent.

Final Thoughts

The scent often associated with older adults can be unpleasant, but it’s usually beyond their control and often linked to health issues. Instead of shunning or criticizing them, we should show understanding and compassion. Remember, we all age, and one day, we might find ourselves in the same situation. Let’s treat our elders with the love and respect they deserve.
