What Causes "Old People Smell" and How to Stay Odor-Free

​As we gracefully age, our bodies undergo numerous changes—some visible, others more subtle. One such subtle change is the emergence of a distinct scent, often referred to as "old person smell." This phenomenon, while entirely natural, can raise questions and concerns. Let's delve into the origins of this unique aroma and explore effective strategies to maintain a fresh and confident presence throughout the aging process.​

The term "old person smell" describes a particular odor commonly associated with the elderly.

In Japan, it's known as "kareishuu"—literally "the smell of gaining years," highlighting its recognition across cultures. This scent is typically characterized as musty, grassy, or slightly greasy. It's important to note that this odor isn't linked to poor hygiene. In fact, experts reveal that with aging, people tend to sweat less. Thus, kareishuu is a natural aspect of aging.

The primary contributor to this distinctive scent is a chemical compound.

As we get older, our skin goes through natural changes that also affect how we smell. One big reason for the so-called "old person smell" is a substance called 2-nonenal. This happens because our skin's ability to fight off certain chemical reactions weakens over time. As a result, natural oils on our skin break down differently, creating a slightly musty or grassy odor.

This process usually starts around 40 years and becomes more noticeable with age. On top of that, our skin produces oils differently as we age, and changes in hormones and metabolism can also play a role in how our body scent develops.

Maintaining personal hygiene is crucial in managing and reducing age-related body odor.

Here are some practical steps:

• Daily showers using mild, pH-balanced soaps can help remove sweat and bacteria, reducing odor.
• Focus on areas prone to sweat accumulation, such as underarms and feet, to prevent bacterial growth.​
• Opt for breathable fabrics like cotton and linen, which allow air circulation and reduce moisture buildup. Regularly washing clothes in hot water can eliminate trapped oils and odors. ​
• Drinking adequate water aids in flushing toxins from the body, potentially reducing the intensity of body odor. ​
• Ensure that living spaces are well-ventilated to prevent the accumulation of odors in the environment.

Diet plays a significant role in body odor. Certain foods can influence the scent our bodies emit.

• Red meat: When you eat red meat, your body releases odorless proteins through sweat. However, when these proteins interact with bacteria on your skin, they develop a stronger scent.
• Spicy foods: Contain sulfur compounds that can be excreted through sweat, contributing to body odor.​
• Processed foods: Often high in refined sugars and additives, which can alter body chemistry and odor.​

While age-related body odor is natural, certain changes may warrant medical attention:​

• Sudden changes: A rapid alteration in body odor could indicate underlying health issues, such as infections or metabolic disorders.​
• Persistent strong odor: If standard hygiene practices don't alleviate strong odors, it may be a sign of a medical condition requiring evaluation.​
• Accompanying symptoms: Symptoms like excessive sweating, unexplained weight loss, or skin abnormalities alongside body odor should be discussed with a healthcare provider.​

It's essential to approach these situations with sensitivity and consult healthcare professionals for proper guidance.​
