How to eliminate the “old person smell”

“Old person smell” refers to the unpleasant odor produced by the accumulation of dead skin cells due to slowed skin metabolism in older adults. Simply put, you can often smell a distinctive odor when you’re near an elderly person; this odor can be strong or faint. How is this smell produced, and how can it be eliminated? Here’s how:

◆How does the “old person smell” develop?

The “old person smell” commonly referred to mainly refers to the odor that may emanate from middle-aged and elderly people around 50 years old, similar to a distinctive body odor. This smell is primarily related to body metabolism, hormones, and personal hygiene.

As we age, our metabolism slows down, and changes occur in sebaceous gland secretion and hormones. Regarding sebaceous gland secretion, in most people, sweat and sebum produced after activity decompose and produce an odor, but this odor can be eliminated by washing. However, older adults experience reduced activity levels or illnesses affecting their metabolism, leading to less frequent washing. This results in a gradual accumulation of dead skin cells, which, when broken down by bacteria, produce an odor. This odor contains a component called “2-nonenal,” which is the main reason for the unpleasant “old person smell.”

◆ How to get rid of the “old person smell”?

To eliminate the “old person smell,” start with daily cleaning and maintenance. Older adults tend to be less active and bathe less frequently, leading to a buildup of dead skin cells. It’s recommended to increase the frequency of bathing to improve this.

When cleansing, pay special attention to areas where dead skin cells tend to accumulate, such as the neck, back, and underarms. Regular, moderate exfoliation is also recommended. After cleansing, apply a moisturizing lotion to help retain moisture and regulate oil-water secretion.

After washing, change your underwear as well, and if convenient, also wash the bed sheets in your dormitory. Choose soft, breathable cotton underwear.

Regularly ventilate the room to prevent odors from lingering.

◆ How to eat to reduce the “old person smell”?

Diet has a significant impact on body odor. Strong body odor is often associated with consuming pungent foods such as onions, garlic, leeks, and strongly flavored spices and meats. To reduce body odor, it’s best to avoid these types of foods.

In your daily diet, increase your intake of fruits and vegetables rich in vitamin C and vitamin E, which are beneficial for metabolism and antioxidation. For example, eat more tomatoes, bell peppers, red amaranth, oranges, and kiwis; and eat more nuts such as almonds, which are also very beneficial to your health.
