What Triggers “Old People Smell” and How to Beat It

As we age, our bodies undergo a variety of changes, some visible, some more subtle. One of the more subtle transformations is the development of a unique scent, often referred to as the “old person smell.” Though this phenomenon is entirely natural, it can raise curiosity and questions. Let’s explore the origins of this distinct aroma and uncover ways to stay fresh and confident as we navigate the aging process.

The term “old person smell” refers to a specific odor often linked to older individuals.

In Japan, this phenomenon is called “kareishuu,” which translates to “the smell of aging,” a term that highlights how this scent is recognized worldwide. It’s typically described as musty, grassy, or faintly greasy. What’s key to remember is that this scent isn’t a sign of poor hygiene. Experts point out that, as we age, our bodies produce less sweat, and this scent is simply a natural part of growing older.

At the heart of this unique odor is a chemical compound.

As we get older, our skin undergoes changes that also impact how we smell. One of the main culprits behind the so-called “old person smell” is a substance called 2-nonenal. This occurs because, over time, our skin loses its ability to counteract certain chemical reactions, leading to a breakdown of natural oils that produce a faintly musty or grassy odor.

This shift typically begins around the age of 40 and becomes more noticeable as we continue to age. Additionally, our skin’s oil production changes, and fluctuations in hormones and metabolism can further influence how we smell.

Tips to maintain freshness and minimize age-related body odor:

• Take daily showers using mild, pH-balanced soaps to cleanse sweat and bacteria.
• Pay attention to areas prone to sweat, like underarms and feet, to prevent bacterial buildup.
• Choose breathable fabrics like cotton and linen, which allow air to circulate and help prevent moisture buildup. Regularly wash clothes in hot water to remove any trapped oils and odors.
• Drink plenty of water to help flush toxins from your body, which can reduce body odor intensity.
• Keep living spaces well-ventilated to avoid the accumulation of odors in your environment.

Diet can affect your body odor. Certain foods can impact the scent your body produces. Here’s how:

• Red meat: Eating red meat releases odorless proteins through sweat. When these proteins mix with bacteria on the skin, they create a stronger odor.
• Spicy foods: Foods with sulfur compounds can be excreted through sweat, contributing to body odor.
• Processed foods: High in refined sugars and additives, processed foods can alter body chemistry and, consequently, body odor.

Although body odor associated with aging is normal, there are times when a change in scent may require medical attention:

• Sudden changes: A noticeable, rapid change in body odor could signal an underlying health condition, such as an infection or metabolic disorder.
• Persistent strong odor: If regular hygiene doesn’t reduce the odor, it might be a sign of a medical issue that needs professional evaluation.
• Other symptoms: If you experience excessive sweating, unexpected weight loss, or skin issues along with changes in body odor, it’s important to consult a healthcare provider.

Approach these situations with care and seek medical guidance when necessary.

As we age, our skin goes through significant changes that impact its appearance and health. Based on expert insights, there are four distinct types of skin aging, each with its own set of needs. Let’s take a closer look at each one and find out how to tailor your routine to keep your skin looking its best.
