Here’s Why ‘Old Person Smell’ Is a Real Thing and How You Can Fix It

As we age, physical changes go beyond just appearance, and one noticeable change is the distinct body odor, often referred to as “old people smell.” This odor is caused by a compound called 2-nonenal, which is produced when hormones change and the body generates more fatty acids in the skin. As we age, antioxidant levels decrease, causing these fatty acids to oxidize and create nonenal, which can remain even after washing and often comes from the chest and back area.

Factors like dirty laundry, confined spaces, dehydration, illness, and medications can intensify the odor. However, there are steps to help reduce it: regular exercise, frequent washing of clothes, a healthy diet rich in antioxidants, staying hydrated, and good hygiene practices. Allowing fresh air into living spaces can also help. While aging is natural, showing respect and love for our elders remains timeless.
