Why do people sniff harder when trying to determine a foul smell?

You want to find out where it is to eliminate it

scent is hard to quantify. \nUsually you have to figure out its components e.g by using gas chromatography or mass spectrography. Then you can figure out the amount of each substance present. \nAlternatively you can measure scent by the reaction of an organism to it, e.g. how much you drool if you smell your favorite food. But that also means the reaction of the organism depends a lot on the scent and organism chosen. For example a male moth will react to one molecule of the pheromone the female moth gives off. I don't know if humans can even smell that stuff.

you probably have some sort of fungus that produces the smell.  kill the fungus, stop the smell.

If there is an unpleasant odor it can be a sign of a yeast infection. I recommend you see your gynecologist and have them do a lab test to tell for sure. If there is a yeast infection a doctor can clear it up in no time.\n\nJust so you know, masking the odor with artificial fragrances will only make matters worse.

The people who thought you were stupid, would KNOW you are stupid if you do it.\n\nWish I knew the details of the effects to help you.  I'm pretty sure that it destroys brain cells and thus causing brain damage.\n\nI guess that means that if you weren't stupid before sniffing, you would be after sniffing.\n\nBest Wishes,\n\nSue

You are inhaling the molecules of the substance. They fit into receptor sites in the nose; are transmitted to the brain area responsible for receiving and decoding them and are interpreted as smell. This is simply put.

In some cultures, body odor is actually preferred to products that cover up or prevent the smell.  There is no hygienic reason to use it.

People can get used to their own smell and not realize that it's offensive to others.  So chances are that the "Something smells in here. Can you smell it too?" approach isn't going to work.  If they knew that they smelled they would (hopefull) do something about it.\n\nIn some cases, when someone doesn't just smell dank but is truly rancid I think it's a passive aggressive maneuver on their part. If the stench is that bad, others who are close to him/her must have mentioned it and the person is choosing to ignore their suggestion/request/plea and is therefore being passive aggressive.\n\nThe easiest way is to enlist a child to inform them of their problem. Kids are brutally honest and people seem to handle their criticism better than an adult's. One morning I hadn't brushed my teeth yet, and my wife's young cousin was sitting next to me on the couch, and I said something to her at close quarters and she scrunched up her face and said "Pew! Your breath stinks!" I laughed, apologized, and went to brush my teeth w/o any hurt feelings.  \n\nIf that isn't an option, the best way is to be direct, but not everyone can be that direct. Although if you can, I would suggest -not- being extremely apologetic, and don't mention that everyone has noticed it, and that it's been going on forever. Best case you say something as soon as possible because to me the real awkwardness comes when the person realizes s/he's been gagging people for weeks or months without realizing. Even if it's a lie you might say that you just noticed it, that way you avoid the "OMG how long has this been going on?" shame.\n\nSo if it were me I would not want, "You're a great person, and we respect you, and [...5 more minutes of buttering up...] but you have an odor problem, and we've all been suffering, and we've been trying to decide how to tell you for the last 6 months." Instead I'd rather get, "Hey, you probably don't realise it but you have a real odor thing going on and it would really help if you could try something different in your routine. I just thought you might want to know, no big deal."\n\nBe direct, be straight, be as concise as you can without sounding like a bastard. Most people try to add as much verbal padding as possible when they are trying to tell someone something that's bad news, embarrassing, etc. Just cut to the chase and get to the point, make the moment only as long as it needs to be.

The sense of smell can convey information about both desirable and undesirable things. If something smells bad and is an unfamiliar smell, you should assume the worst and try to avoid breathing it. You should try always to know what is in the air you breathe. Even if something smells good you should be wary. Manufacturers routinely add deodorants or masking scents (like pine, lemon, etc.) to products that contain solvents or other toxic materials, so knowledge of what they contain is essential.

Hmmm. . . are you sure that the "over 18s" actually have a better sense of smell or are they just better at identifying what they're smelling?

Certain foods can cause odors to be secreted from the body within sweat or other bodily fluids (ie: garlic, onions). \n\nBad breath can be caused by not doing a thourough cleaning of the tongue. Also, alchohol, including mouthwashes containing it, make bad breath worse.\n\nIt may not be the person themselves causing the odor. It could be the clothes they are wearing. Certain odors from the surrounding air/environment can embed themselves in clothes (ie: cigarette/cigar smoke odors). Also, if they are not washing there clothes in hot enough water bactera can still be present on them. We all know bacteria thrives in moist, dark areas so if the bacteria is present for example in the armpit of a shirt, if the individual wearing it perspires, this moisture combined with the darkness of the armpit area can cause the bacteria to thrive and produce an odor. \n\nWhen we think of "B.O." we think of the stink being screted by the individual themselves when in fact sweat dosn't stink at all. It is the bacteria that causes the smell.\n\nA natural way to rid the body of odor would be to wash frequently to prevent bacteria growth and to avoid foods with strong flavours and odors.

I was in a simular situation when I was a manager.  I had an employee that was offending customers.  I had no idea how to approach this person with fear that their reaction would be with anger and/or embarrassment.  It wasn't until someone in a higher position gave me this advice.....\n\nThe person who has the body odor doesn't understand the concept of cleanliness as you do.  So, approaching them you will notice that they may be oblivious to the situation.  My experience was that I was educating them on cleaniness.  Once achieved, this should favor both parties.  \n\nAlthough the person I delt with never changed their ways, probably because we weren't friends and that this person was a bad employee.  Your situation is different.  Still, it's worth the effort to educate....\n\nHope this helps you.\n\n:)\nPeace

If you are letting smelly ones you don't want people to know who passed it, so you slip it out quietly and wait to see who gets blamed.\n\nIf you KNOW it isn't a stinker you want to get credit for it so you push it out as loud as you can.\n\nThe inverse relationship becomes apparent when you fit a regression curve to experimental data. This gives us the equation...\n\n   loudness = ( distance_to_others / smelliness )^2

better than we can smell up here in the air. it's one of the main senses they use for finding food and evading danger.

Some peoples' natural pH levels cause them to have unpleasant odors coming from their nether-region. It's kind of like how some peoples' BO smells worse that others--it's a scent they naturally produce.
