What Causes Body Odor in Older Adults?

causes of body odor in seniors

 

Aging brings many changes, and one of them is a change in body odor. Whether caused by hormonal shifts, lifestyle factors, or the natural aging process itself, body odor in older adults can be managed effectively. Here’s how caregivers can help their loved ones stay fresh, confident, and comfortable.

Caregivers may sometimes notice a grassy or greasy scent on their aging care recipients. Commonly referred to as “old person smell,” this distinct odor, known medically as nonenal, is a normal part of aging that typically begins around age 40 and becomes more noticeable over time.

Nonenal forms when the natural oils in aging skin break down. Specifically, omega-7 unsaturated fatty acids oxidize, producing a compound called 2-nonenal. Around middle age, the body’s natural antioxidant defenses begin to decline, allowing this process to occur more readily. A study published in the Journal of Investigative Dermatology confirmed that 2-nonenal is a key contributor to age-related body odor, detectable in individuals aged 40 and older (PubMed).

Because 2-nonenal is not water-soluble, it can linger on the skin even after bathing. As a result, the “old person smell” can persist on the body as well as on fabrics like clothing, bedding, and upholstery, even in clean environments.

Common Causes of Body Odor in Older Adults

Hormonal Changes

Aside from the naturally occurring chemical compound, nonenal, other changes contribute to body odor in older adults. Hormonal changes lead to an increase in lipid production, which oxidize and form nonenal. Research in Free Radical Biology and Medicine indicates that oxidative degradation of omega-7 fatty acids in skin lipids produces 2-nonenal, reinforcing how age and hormonal shifts combine to create body odor (PMC).

Menopause is an event during which women experience major hormonal shifts. Women of menopausal age may develop higher body temperatures and sweat as a result of hot flashes. Estrogen levels decline during menopause, causing the composition of sweat to become more odorous.

A higher level of testosterone develops in the sweat as a result of decreased estrogen in menopausal women, which can attract bacteria and produce body odor. Stress and anxiety increase at this stage, too, and trigger sweating from odor-producing apocrine glands.

Dietary Changes

What a senior eats also affects how they smell. The familiar culprits, garlic, onions and spices, are known to release sulfurous compounds that are excreted through sweat and pores. Foods loaded with spices cause the elderly to perspire more, which produces more body odor.

Similarly, processed foods cause body odor. Foods containing sugar, salt, and additives are processed quickly by the body but affect gut bacteria, causing an overgrowth of odor-producing compounds. Processed foods high in fat slow digestion or break down into odorous substances.

Health Conditions

Certain illnesses, like diabetes and kidney disease, are common among the aging population. Diseases like these can change how the body smells. When the aging body breaks down fat instead of glucose in cases of uncontrolled diabetes, ketones build up and cause a fruity smell in the breath and sweat.

Kidney disease causes damage to the kidneys. As a result, the damaged organs are unable to properly filter waste from the blood. The buildup of waste in the body is released through the breath and skin as an ammonia-like or fishy smell.

Infections, particularly bacterial and fungal, can produce a foul odor on the skin. A healthy balance of bacteria is normally present on the skin. However, infections cause bacteria to multiply, especially in moist areas, like skin folds. Bacterial waste produces strong, offensive smells.

How Do Seniors Manage Body Odor?

While a change in body odor is expected as people age, it can be minimized by following a healthy lifestyle. Hydration is key to reducing body odor as it supports the body’s detox process. By drinking water throughout the day, seniors flush out toxins from the body and decrease odors.

Eating a clean diet is also helpful in reducing odors. Limit foods, such as garlic, onions and processed foods, that are known to affect body odor. Instead, promote a healthy internal balance by consuming more fruits and vegetables, which are rich in antioxidants that aid the natural detoxification process.

Water-rich foods, like watermelon and cucumber, dilute the fatty acids that contribute to body odor. Leafy greens high in chlorophyll also help neutralize body odor. Citrus contains compounds that neutralize the effect of odor-causing foods, like those rich in sulfur.

Minimize body odors by wearing breathable fabrics. Clothing made of cotton or linen absorbs moisture and allows sweat to evaporate more readily, preventing odor-causing bacteria from thriving. Polyester and other synthetic fabrics, on the other hand, trap sweat and allow bacteria to multiply.

Seniors should take regular baths or showers to clean sweat from their bodies. Exfoliate the skin occasionally to remove dead skin cells that can contribute to odors. Change into clean clothes daily, and especially after exercising, to reduce unwanted body odor.

Stair Safety for Seniors: 8 Ways to Prevent Falls at Home

If your senior loved one hopes to age safely in their own home, ensuring a secure living environment is essential. One of the most important areas to focus on is the stairs—whether they lead to a basement, a second-floor bedroom, or even a backyard. Stairs can pose a significant risk of falls, so taking steps to make them safer is a crucial part of protecting your loved one’s independence and well-being.

For families in Weston and the surrounding Broward County communities, many homes are multistory. That makes stair safety especially important for older adults who want to remain in the comfort of their own home.

How Stairs Can Be Dangerous for Seniors

In the United States, more than 1 million people are injured on stairs each year, an average of about 3,000 injuries per day, or one every 30 seconds. The risk of stair-related injuries increases as we age, due to decreased coordination, reduced strength, and changes in vision, all of which can make navigating stairs more challenging.

Research shows that adults aged 60 and older are at a higher risk of hospitalization from stair-related injuries. Certain health conditions can further increase this risk. For example, osteoporosis can make bones more fragile, while anticoagulant medications can lead to serious complications such as intracranial bleeding if a fall occurs.

Falls can also be triggered by a variety of underlying issues—balance problems, medication effects, chronic pain, or neurological changes. To better understand the most common reasons seniors experience falls, you can read our resource on Why Seniors Keep Falling.

Stairs are common in American homes, with more than half of all houses containing them. In some regions, like New England and the Middle Atlantic, more than 90 percent of homes are multistory, making stair safety an important concern for older adults.

Quick Ways to Make Stairs Safer for Seniors

If you are worried about your loved one’s safety on the stairs, here are some simple changes that can have a big impact:

  • Add non-slip treads or low-pile, tightly fitted carpet
  • Improve lighting at the top and bottom of the staircase
  • Install sturdy handrails on both sides of the stairs
  • Mark the edge of each step with contrasting or reflective tape
  • Remove clutter, loose rugs, and decorative objects
  • Consider a stair lift if your loved one frequently avoids the stairs

These changes, combined with regular supervision and support, can greatly reduce the risk of stair-related falls.

How to Make Stairs Safer for Seniors at Home

Falls can have serious consequences for older adults, which is why it’s so important to be proactive in reducing the risk. One of the most effective ways to do this is by making thoughtful design and environmental changes in the home. Here are some practical strategies to make stairs safer for seniors:

Add Traction to the Stairs

Most stair-related injuries occur from slipping rather than tripping, which makes reducing slipperiness a top priority. If your stairs are made of wood or tile, consider adding materials that increase traction, such as:

  • Rubber or abrasive stair treads
  • Anti-slip tape
  • Skid-resistant floor treatments

Low pile carpeting that is tightly fitted and securely attached can also help prevent slips. Additionally, encourage your senior loved one to wear proper footwear with a firm, rubber sole when using the stairs to further reduce the risk of falls.

Light Up the Stairs

Poorly lit stairs significantly increase the risk of slips and injuries, and in many homes, stairwells are more dim than other areas. Installing bright, even lighting makes it easier for your senior loved one to see each step, especially at the top and bottom, where most falls occur. Ideally, there should be a light switch at both the top and bottom of the staircase, or one can be installed if it’s not already in place. For added safety, consider wall-mounted, wireless motion-sensing night-lights positioned at foot and ankle level to guide each step in low-light conditions.

Increase Visual Cues

If your senior loved one has difficulty distinguishing individual steps, especially when the stairs are all the same color, adding reflective or colored tape to the edge of each step can help them see where one step ends and the next begins. Another option is to paint the vertical portion of wooden steps (the risers) white or a contrasting color, which clearly separates the tread, the part of the step meant for stepping, from the riser and makes each step easier to navigate.

Ensure Consistent Height and Depth

To help prevent tripping, it’s important that both the horizontal (tread) and vertical (riser) surfaces of each step are uniform in size. Stairs with inconsistent widths or varying heights can easily cause missteps, especially for seniors who may have reduced coordination or depth perception. Ensuring that every step is the same size and shape creates a predictable, safe surface that makes navigating the stairs much easier and reduces the risk of falls.

Get Rid of the Bottom-Step Illusion

In some older homes, the bottom step can blend in with the landing, creating a potential hazard. An elderly person may mistakenly think they are stepping onto a flat surface, increasing the risk of a fall. To prevent accidents, it’s important to clearly distinguish the bottom step from the rest of the landing. This can be done by adding a rubber tread or anti-slip tape, or by upgrading the step to match the design and color of the other stairs, making it easier to see and safely navigate.

Make Upgrades to the Handrails

Handrails are a crucial safety feature in any home, as they provide support, improve balance, and help prevent falls on stairs. Unfortunately, in many homes, they are more decorative than functional. For maximum safety, handrails should be rounded so that a hand can fully grasp and encircle them. Consider installing rails on both sides of the staircase, running the full length of the stairs, and positioned 30 to 36 inches above the floor. Properly installed handrails give seniors the stability they need to navigate stairs safely.

Remove Clutter

It’s important to keep stairways completely clear of clutter to eliminate any risk of tripping or falling. Items such as shoes, books, or decorative objects should never be left on the stairs, and any throw rugs should be removed, as they can easily slip or bunch up underfoot. Maintaining a clean, unobstructed pathway ensures that your senior loved one can navigate the stairs safely and with confidence.

Install a Stair Lift If Needed

If your senior loved one has significant difficulty navigating stairs, a motorized stair lift may be a practical solution. These lifts typically cost between $2,000 and $10,000, and in some cases, you may be able to claim part of the expense through insurance. Installation is usually completed in a single day, but it’s important to ensure that the stairway is wide enough to accommodate the chair while still allowing others to use the stairs safely. The lift can also be easily removed if you decide to sell the home, making it a flexible option for improving stair safety.
