Because stimulants, including coffee and tea, contribute to body odor by increasing the activity of apocrine sweat glands, try eliminating these beverages and any others containing caffeine. Splash rubbing alcohol in the armpits to reduce bacteria on the skin.
Coffee. There's a reason why "coffee breath" is a marketing tool: Furthermore, the diuretic nature of coffee dries out the mouth, which harbors the growth of bacteria and creates an universally unpleasant smell. According to Andrew Weil, MD, this can extend to your body odor as well.
Caffeine has been demonstrated to enhance olfactory function in rodents, but to date, the sparse research in humans has not shown any equivalent effects.
Causes of body odour
hormonal changes. being overweight. having a condition like diabetes, kidney disease or liver disease. certain types of medicine, such as antidepressants.
Coffee beans are roasted to bring out the aroma and flavor locked inside of them. This roasting process causes sulfur-containing aroma compounds to form. These sulfuric compounds and the acid in coffee can cause bad breath. Additionally, drinking coffee causes dry mouth.
If you have diabetes, a change in body odor could be a sign of diabetes-related ketoacidosis. High ketone levels cause your blood to become acidic and your body odor to be fruity. In the case of liver or kidney disease, your odor may give off a bleach-like smell due to toxin buildup in your body.
Hormone imbalances and body odor often go together. Dips in estrogen can trigger hot flashes and night sweats, meaning you simply sweat more, which in turn can result in more odor.
When the bacteria break down the sweat they form products called thioalcohols, which have scents comparable to sulfur, onions or meat. "They're very very pungent," says Bawdon.
If your body is dehydrated, you are unable to release these toxins (bacteria), which when accumulated leads to an unpleasant body odor, especially in the armpits, feet, and groin area.
Apocrine glands are found in areas where you have hair, such as your armpits and groin. These glands release a milky fluid when you're stressed. This fluid is odorless until it combines with bacteria on your skin.
Nasal or sinus congestion (swelling) during the early stages of a COVID-19 illness also prevents smell molecules from getting where they need to be—the narrowest point in the nasal cavity— to be sensed. By the time the swelling caused by congestion goes down, the damage to the olfactory nerves may be done.
Pending on the type of coffee you buy (light roast vs medium roast vs dark roast), there's a good chance that oils have built up within your grinder and are causing the rancid, fishy smell.
Skin conditions
Internal health issues may result in unpleasant body odors (BO), as well, such as liver and kidney disease and hyperthyroidism, which can lead to excessive sweat and increased BO. Stagg recommends talking with your doctor if you notice a strong smell from your skin.
What you eat affects your body odor. Foods that tend to make you sweat more, such as hot peppers or other spicy foods, might also lead to body odor. And the aroma of foods like onions or garlic can be carried in your sweat. Drinks with caffeine or alcohol may also make you sweat more.
Bromhidrosis is a disease that occurs when the bacteria on your skin breaks down sweat and produces an abnormally offensive smell similar to onions or sulfur. Bromhidrosis body odor is more pungent and persistent than ordinary B.O. There are two types of bromhidrosis: apocrine and eccrine.
Despite our best efforts to keep them clean, towels often develop a less-than-fresh smell. One of the main causes of this is detergent build-up. Over time, soap residue accumulates in the fibres of the towels, stopping them from absorbing as much water as possible, and from drying as well as they could.
The menopausal drop in estrogen also leaves our bodies with relatively higher levels of testosterone — produced by our ovaries in small amounts — than before. This can attract more bacteria to sweat, making it smell funkier.
Thyroid problems.
Occasionally, an overactive thyroid can also cause body odor. This is because the patient tends to sweat excessively due to the hyper-functioning thyroid gland. This condition can also be ruled out by physical examination and blood studies.
Different hormones, different aromas
During menopause, your hormonal balance shifts. This shift can also lead to stronger body odor. Estrogen and progesterone levels fall relative to your testosterone, while cortisol tends to increase.
Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. It's also called "fish odour syndrome". Sometimes it's caused by faulty genes that a person inherits from their parents, but this isn't always the case. There's currently no cure, but there are things that can help.
Olfactory reference syndrome (ORS), also known as olfactory reference disorder, is an underrecognized and often severe condition that has similarities to obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD). People with ORS think they smell bad, but in reality they don't.
You're sweating more than usual.
"When we sweat, natural bacteria on our skin breaks down the perspiration into thioalcohols, [so] the body odor we notice is thanks to bacteria interacting with our sweat," explains Shein.
