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.
After your shower or bath, apply an antiperspirant and deodorant. Most over-the-counter antiperspirants contain aluminum-based compounds that block your body's eccrine glands, preventing you from sweating. Deodorants repel the bacteria that cause odor, and may contain an additional fragrance.
Showering destroys these happy bacterial colonies; they're completely wiped out by all of our frequent rubbing and scrubbing. And when the bacteria washed off by soap repopulate, they tend to favour microbes which produce an odor – yes, too-frequent showering may actually make you smell more.
Baking Soda
This might be a pretty straightforward remedy to get rid of smelly armpits. 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.
If you're worried you're one of these people, one trick is to lick your wrist, wait ten seconds, then sniff the patch you licked: If it smells, chances are, so does your breath. An even more reliable method, of course, is simply to ask someone.
Groin sweat contains fatty acids and proteins which feed bacteria. As the bacteria break down the nutrients in groin sweat, foul-smelling acids are left behind.
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.
Ask to speak in private. Be direct (“I'm not sure if you're aware of this but you have a strong odor about you.”) Reserve judgment ( “I don't know if it's from your clothing or if it's a personal hygiene issue.”)
In fact, according to research published in Nature, your nose can detect about one trillion smells! But your own underarms could reek and you might not be able to tell: Humans are prone to what scientists call olfactory fatigue; our sense of smell just gets plain tired out by familiar odors and stops detecting them.
Parosmia is a distorted sense of smell. Things that used to smell pleasant now smell foul to people with parosmia. People get parosmia for many reasons, including infections, medications and trauma. You can't always prevent it, but in most cases, it's temporary.
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.
