Phantosmia (phantom smell), also called an olfactory hallucination or a phantom odor, [1] is smelling an odor that is not actually there. This hallucination is intrinsically suspicious as the formal evaluation and detection of relatively low levels of odour particles is itself a very tricky task in air epistemology.
Age is the strongest reason for olfactory decline in healthy adults, having even greater impact than does cigarette smoking. Age-related changes in smell function often go unnoticed and smell ability is rarely tested clinically unlike hearing and vision. 2% of people under 65 years of age have chronic smelling problems.
The olfactory epithelium plays a large role in why humans are attracted to persons biologically rather than physically; this relates directly to the sense of smell and not physical appearance. Olfactory communication is common in all animals and recent studies have shown that humans have this communication trait as well. This kind of ...
Boogers trap invading viruses and bacteria before they can enter your body, so eating boogers might expose your system to these pathogens. See more stories on Insider's business page . Following ...
Apparently, garlic—like all its cousins, including onions, leeks, scallions, chives, and shallots—contains a sulfur-based compound called Allicin that has powerful antioxidant health benefits ...
The major volatile compounds responsible for garlic breath are allyl methyl sulfide, allyl methyl disulfide, allyl mercaptan, diallyl disulfide, dimethyl disulfide and methyl mercaptan, along with minor amounts of dimethyl selenide. [1] [2] [3] Various other sulfur compounds are also produced when allicin in garlic is broken down in the stomach ...
Smell events are often sporadic and episodic in nature (based on diet over the previous 24 hours), making it often difficult to diagnose by smell alone. Some people with trimethylaminuria report having a strong odor all the time, but there has not been any evidence apart from self reported symptoms that this is the case. [citation needed]
For example, some animal species that feign death to survive (like opossums), in this state produce a strong body odor to deceive a predator that the prey animal has been dead for a long time and is already in the advanced stage of decomposing. Some animals with strong body odor are rarely attacked by most predators, although they can still be ...
