"Apple cider vinegar is a great natural underarm deodorant," says Georgianna Donadio, PhD. She suggests applying it directly to your armpits to kill body odor.
Pre-treat problem areas
White vinegar can help to neutralize and remove perspiration odor from clothes. Add one cup of white vinegar to a tub of warm, clean water, and soak garments for two or three hours before you wash them in the machine on their usual cycle.
White Vinegar
White vinegar is a powerful odor neutralizer and works wonders on underarm areas of fabrics.
As the sweat components break down, this can lead to unpleasant odors forming on your clothes. And, if you don't get rid of the sweat smell from your garments effectively, it can build up over time, resulting in a closet full of clothes that still smell of sweat even after washing.
While in the shower fill your hand with hydrogen peroxide and splash and rub it into each of your underarms. At the end of the shower you may rinse it off with water only (This will kill some of the bacteria and is effective) Shave or remove your underarm hair (this decreases sweat production)
When the sweat from your glands meets the bacteria on your skin, it breaks down into products called thioalcohols. The thioalcohols give off a strong, often sulfurous scent that can also be comparable to onions or meat. Genetics plays a role in how many thioalcohols your body produces.
Most of the time body odor isn't a problem and a shower will quickly wash it away. But if you notice a change in body odor or you're sweating much more than usual, it could be a sign of a medical condition that needs treatment.
Your skin has more time to absorb the compounds and work effectively. If you do experience additional underarm odor, try switching your deodorant or antiperspirant. You can try clinical-strength or prescription options, or natural deodorants.
Do older people have more body odor? It seems that seniors do stink more than younger people. Aren't we lucky? A Japanese study published in the Journal of Investigative Dermatology found that 2-Nonenal, a recently found substance in human body odor, tends to increase with aging.
Baking Soda
Baking soda helps in neutralising underarm odor by absorbing sweat, balancing the pH levels and suppressing bacterial growth. You can use baking soda as a talc. Pat it in your underarms and dust off the excess once dry.
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.
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.
Expect to Detox
If you've been using conventional deodorant or antiperspirant for years, it can take 2-4 weeks to detox and release all of the aluminum in your pits that's been preventing you from sweating.
“Lemons can temporarily decrease odor in the armpits, and the alpha-hydroxy acid in citric acid can kill odor-causing bacteria,” Dr. Geeta Yadav told Shape in an interview, but added that “antiperspirant and deodorant are a much better and safer way (than using lemons)” when it comes to diminishing body odor.
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.
Apple cider vinegar not only cuts fat but also removes dead cells as it contains mild acids that are natural cleansers. Mix two tablespoons each ACV with baking soda and apply this mixture on your armpits. Now leave it on for five minutes and rinse it with cold water when dry.
Sprinkle the mixture onto fabric surfaces, including carpeting, and let sit for 30 minutes or overnight. Vacuum up the baking soda mixture, and with it, those bad smells.
Trick your olfactory system
Try this: sniff coffee or charcoal for a full minute. Then go back and take a whiff of your underarm or other potentially offending area. In a pinch, you could even smell the crook of your elbow, which contains few sweat glands.
At about age 40, the body subtly changes the way omega-7 unsaturated fatty acids on the skin are degraded. These acids get exposed to the air and create a compound called “nonenal.” Nonenal most likely gets produced due to hormone imbalances.
