Body odor (BO) that persists after showering is usually caused by deodorant buildup on the skin, trapped bacteria in body hair, or lingering odor molecules stuck in the fabric of your clothes.
Your clothes smell like B.O. after washing because trapped bacteria and oily antiperspirant residue are reacting with your body heat. This is especially common with synthetic fabrics like polyester, which act like magnets for oils and odors.
Fortunately, getting rid of bacteria-induced odor can be as easy as switching your body wash or soap. “Use it daily or twice daily, without scrubbing,” Dr. Goldstein says. Also, wear moisture-wicking clothing and dry off your armpits completely after showering.
Body odor is caused by a mix of bacteria and sweat on your skin. Your body odor can change due to hormones, the food you eat, infection, medications or underlying conditions like diabetes. Prescription-strength antiperspirants or medications may help.
To quickly eliminate persistent body odor, wash daily with an antibacterial soap, apply a clinical-strength antiperspirant at night, and wear loose-fitting natural fabrics like cotton. Sweat itself is odorless; body odor occurs when bacteria on your skin break down the sweat.
To naturally deodorize your armpits, focus on neutralizing odor-causing bacteria rather than blocking sweat. Try these safe, highly effective methods:
Take a daily shower (or two, if you're in a hot, humid area), and pay extra attention to the regions with the apocrine glands. Use antibacterial soaps or cleansers designed to kill bacteria, like a benzoyl peroxide. Use antiperspirants with a higher percentage of active ingredients, or a prescription-strength option.
Persistent armpit odor happens when naturally occurring bacteria break down sweat on your skin. If it won't stop, you might have stubborn bacteria trapped in your pores or fabrics, be using the wrong product, or experiencing shifts in diet, hormones, or underlying health.
Body odor can be directly influenced by specific vitamin and mineral deficiencies. Correcting these nutritional gaps may help neutralize unpleasant scents.
Diabetic sweat typically smells sweet, fruity, or similar to acetone (nail polish remover). This distinct odor is caused by a buildup of ketones, which occurs when the body burns fat for energy instead of glucose.
Why do my armpits still smell even after antibacterial soap? Antibacterial soap can reduce surface bacteria, but it can't eliminate it all. Bacteria can multiply quickly, especially in warm areas like your underarms. That's why odor can come back soon after showering.
Antiperspirants or deodorizing sprays can help you manage body odor in the armpits. If these don't work, a doctor might recommend Botox injections, laser therapy, or even surgery. Good hygiene, loose-fitting clothes, reducing stress, and possibly shaving or waxing the area might help prevent or reduce body odor.
Armpit odor usually isn't caused by sweat itself, but by bacteria on your skin breaking that sweat down. If deodorants aren’t working, you might be dealing with excess moisture, trapped odor in your clothes, or a need to switch to an antiperspirant.
The characteristic "old age smell" is scientifically known as nonenal (or 2-nonenal). It is a chemical compound produced when the skin's natural oils and fatty acids break down and oxidize as we age.
'Removing clothes within 30 minutes (or even sooner) is a good habit to get into, as it helps prevent that stale odour from forming. Leaving damp laundry in the machine for several hours can undo lots of the freshness you've just achieved with detergent and fabric softener, meaning you may need to rewash the load. '
Certain foods cause body odor when their volatile compounds (often sulfur) are absorbed into your bloodstream and released through your pores. Others stimulate your sweat glands or slow down digestion, allowing naturally occurring skin bacteria to break down the resulting sweat into foul-smelling acids.
High blood sugar (hyperglycemia) occurs when your body doesn't produce enough insulin or can't use it effectively. Five common warning signs include:
Persistent bad body odor (bromhidrosis) can be a symptom of an underlying medical condition. While typical odor comes from bacteria breaking down sweat, specific health conditions can alter your natural scent in distinct ways.
A dark patch (or band) of velvety skin on your neck, armpit, groin, or elsewhere could be a sign of pre-diabetes. The medical name for the condition that causes this velvety skin is acanthosis nigricans.
When your vitamin B12 is low, you most commonly crave meat, fish, and eggs. Because your body is trying to self-correct, it instinctively signals a desire for nutrient-dense animal products that naturally contain the highest amounts of B12.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
When your body is in ketosis, your urine typically smells sweet, fruity, or like nail polish remover (acetone). This happens because excess ketones (specifically acetoacetate and acetone) are produced as your body burns fat for fuel and excretes the overflow.
Wash daily with a mild soap
Using warm water and anti-bacterial soap will help kill off bacteria that lives off your sweat. It may mean taking more than one shower a day, or just a quick clean at the sink with soap, a wash cloth, and warm water.
Low estrogen, common during perimenopause and menopause, typically causes body odor to become more intense, musky, or sour due to shifts in sweat composition and vaginal pH. Vaginal scent may change to become more alkaline, sometimes described as slightly sweet, bready, or yeasty. Other common smells include a sharper, stronger, or onion-like scent underarms or in the groin.
Body odor (BO) is technically odorless on its own. It occurs when bacteria on your skin break down the sweat secreted by your apocrine glands. If you always smell like BO, it usually means something is causing an imbalance in your skin’s bacteria, your sweat production, or your internal body chemistry.
