Bromhidrosis is foul-smelling body odor related to your sweat. Perspiration itself actually has no odor. It's only when sweat encounters bacteria on the skin that a smell can emerge. Other than body odor (BO), bromhidrosis is also known by other clinical terms, including osmidrosis and bromidrosis.
This is perfectly natural, even if it “stinks.” 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.
Baking soda: Make a paste using baking soda and water. Apply the paste to your armpits and let it dry. Baking soda balances the acid on your skin and reduces odors.
One of the by-products of their metabolism is a group of sulphur-containing chemicals called thioalcohols. The exact thioalcohols produced will depend on your unique menagerie of skin bacteria, but some thioalcohols do indeed smell strongly of onion.
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor.
Garlic, onions,egg, and cruciferous vegetables — such as broccoli and cauliflower — can cause odour,” Dr Anupam Dey, a Kolkata-based dietician says. So, if you are eating high levels of certain foods, foul-smelling compounds they contain may be excreted through your sweat glands to give an unpleasant odour.
Toothpaste and mouthwash can eliminate the sulfuric chemical compounds in onions that leave a lingering smell. Rub your hands together with toothpaste and mouthwash under running water for around thirty seconds.
What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.
If you want a much faster way of getting rid of that smell, skip the soap and rub your hands with a spoon. You can actually use any stainless stainless steel object: spoons, forks, your sink. Just hold your hands under cold running water while rubbing the object for 10 seconds. The smell slips off almost like magic.
Things like stress, hormonal changes, new medications, and different lifestyle factors (like harder workouts or shifts in the weather) can all impact how you sweat, and your go-to deodorant may not be able to stand up to the new situation.
Your environment, the things you eat, medications you take, shifts in hormone levels, or underlying disorders may all be behind a sudden change in body odor. Changes in body odor can be a normal part of development, such as when an adolescent is going through puberty.
A dry mouth allows bacteria to thrive. Bacteria that live in the mouth can make compounds that have sulfur. These compounds are especially stinky. They can smell like rotten eggs or onion, for example.
Onions are strong tasting and smelling because they contain a lot of sulfur derivates, like thiosulfinates and thiosulfonates.
"Perspiration levels are not as high compared to daytime and usually the 'deodorizing' is most important during the daytime. While using it occasionally at bedtime is not harmful, use of deodorants around the clock may be an additional source of unnecessary irritation to the skin."
Shower More Frequently. Infrequent showering can cause bacteria to build up on your skin. Shower at least once a day (or every morning and night) and scrub your extra-sweaty areas with a scent-free, antibacterial bath soap. Stay away from strongly scented soaps, which can make your armpits smell worse.
The best way to prevent smelly armpits is to wash daily and after sweating. Using antiperspirant or deodorant and shaving the armpits can also help. Avoiding alcohol and certain foods, such as onions and garlic, will also help prevent smelly armpits in some cases.
Baking Soda
You can take a small amount of baking soda and mix a little bit of water to form a semi-solid paste. Apply this paste to your armpits and allow it to dry. After it dries, wash it off. This might prove to be a good remedy for smelly armpits.
What to do: Mix 1 tablespoon of bentonite clay (I recommend the Aztec Secret Indian Healing Clay) with ½ tablespoon ACV until it becomes a paste. Apply onto clean armpits and leave on 15-20 minutes or until dry. Rinse off and pat dry.
If the deodorant doesn't work, consider another old-fashioned remedy you haven't tried: baking soda. It changes the pH of the armpit and helps to keep it dry, and both of those things help get rid of odor. Underarm odor is caused by bacteria that live on our skin; the sweat is odorless.
