Most often, they are the result of small, easily ignored habits that gradually accumulate over time.
Below, we present eight common but often overlooked habits that can contribute to unwanted body odor in older women, as well as practical and simple ways to address them.
1. Wearing synthetic fabrics too often
Many modern clothes are made of polyester or blended fabrics that are wrinkle-resistant and last longer. However, these materials tend to trap heat and moisture, creating the perfect environment for odor-causing bacteria to grow, especially as sweat changes as we age.
Why is this important:
As estrogen levels decrease, sweat becomes more concentrated and has a strong odor, making the use of breathable fabrics increasingly important.
What helps:
Choose natural fibers such as cotton, linen, bamboo or modal, especially for underwear, bras and tops worn directly against the skin.
2. Wearing bras or underwear for too long
Bras, shapewear, and similar garments absorb sweat, oil, and bacteria, even if they don’t look dirty. Wearing them for several days in a row leads to the gradual and unnoticeable development of an unpleasant odor.
Why is this important:
The area under the breasts is particularly prone to moisture and bacterial growth, which can cause a sour or musty odor.
What helps:
Change your bras every day and wash them after one or two wears. Make sure they are completely dry before wearing them again.
3. Not drying yourself enough after bathing
Moisture trapped in skin folds – such as under the breasts, between the toes, around the groin, or behind the knees – can quickly promote the growth of bacteria or fungi.
Why is this important:
Aging skin is thinner and more delicate, making it more prone to irritation and odor when it is wet.
What helps:
Gently pat your skin dry. A cool blow dryer or fan can help get to hard-to-reach areas. Some women also find unscented or antifungal body powders helpful.
4. Using perfume to mask odors instead of removing them
Applying perfume over existing body odor often intensifies the odor rather than improving it.
Why is this important:
Perfumes can chemically react with sweat and bacteria, which can sometimes cause a stronger or more acidic odor.
What helps:
Preventing unpleasant odors is a priority. Perfume should only be applied to clean, dry skin and with caution.
5. Changes in oral health and dry mouth
Aging, menopause, and some medications can reduce saliva production, which can lead to chronic bad breath, even with regular tooth brushing.
Why is this important:
Saliva helps naturally get rid of odor-causing bacteria. When saliva production decreases, odors last longer.
What helps:
Brush your tongue daily, clean your dentures thoroughly, stay hydrated, and see your dentist regularly. Sugar-free lozenges can also help stimulate saliva production.
6. Wearing shoes that don’t dry completely
As you age, changes in blood circulation can increase foot sweating. Frequent wearing of closed shoes without drying them out leads to moisture retention and unpleasant odor.
Why is this important:
Bad foot odor can spread to your socks, the floor, and even the surrounding area of your home.
What helps:
Change your shoes daily, air them out completely, use moisture-wicking insoles, and choose breathable shoes whenever possible.
7. Hormonal changes that affect body odor
Menopause can change the smell of sweat, even if sweating itself decreases.
Why is this important:
Hormonal changes alter the bacterial flora of the skin and the composition of sweat, sometimes leading to a stronger or unusual odor.
What helps:
Use a gentle antibacterial soap on odor-prone areas, such as the armpits, groin, and feet. Avoid harsh rubbing, which can irritate the skin.
8. Infrequent washing of towels, bed linens, and clothes
Even freshly washed leather can quickly absorb odors from fabrics that are not cleaned frequently enough.
Why is this important:
Bacteria and grease accumulate in towels and bedding and are transferred back into the body.
What helps:
Wash towels every second or third time and bed linens at least once a week, using hot water if possible.
The last word
Changes in body odor are a normal part of aging and are related to hormones, skin changes, medications, and lifestyle, not to personal flaws. In most cases, odor problems are resolved with small, intentional changes rather than drastic measures.
If the odor persists despite good hygiene, it is a good idea to see a doctor. Sometimes infections, metabolic changes, or side effects of medications can play a role.
Aging with dignity means understanding your body, not blaming it.
