Many people think they have physical reactions to odor when in fact their reaction is emotional or psychological. Unfamiliar odors often cause people to worry about possible chemical hazards, and worry can lead to a variety of effects. However, the human nose is a very sensitive detector of airborne chemicals and can often detect chemicals that are present in such low concentrations that they cannot cause any kind of direct effect. While some people are allergic to complex molecules that may be airborne, some of which cause odors, many odorous materials have simple structures that do not trigger human allergy. Certain vapors may cause effects like anesthesia (diethyl ether, chloroform), direct tissue damage (phosgene) or even death (hydrogen cyanide).
