The odors stemming from bodies that had begun to behave as if they were sick were found to smell more aversive, proving that disease smells. The odors were sniffed by a panel of 40, who described their intensity and pleasantness.

Body odors were then collected from the armpits of t-shirts worn by volunteers, ready for inspection by a panel of judges whose noses were trained for the occasion. The team injected human volunteers with lipopolysaccaharide, a compound known to activate the innate immune system and inflammatory responses in humans as if they were fighting bacteria.īy injecting eight volunteers with either the compound or a placebo, bodies were made to behave either as if they were sick or healthy. “People should be able to detect when someone is contagious,” said Olsson, who sniffed out the truth in a recent study. The process is thought to be evolutionary among humans who sense the change and steer clear – to stay healthy. Olsson’s team set out on a more general challenge: to explore how odors can reveal when someone is sick, or recently infected. Preti has been studying body odor for more than 30 years.”I ride public transport a lot, and every now and then, I come across someone emanating a strong odor, and it’s obvious,” Preti said. The change is subtle, however, and more easily picked up by a trained nose, such as that of George Preti, an organic chemist at the Monell Chemical Senses Center. ![]() Several diseases have been discovered to harbor signature scents on the body in recent studies, including people with typhoid fever reported to smell like baked bread, people with yellow fever smelling like a butcher’s shop and the glandular disease scrofula leaving people smelling like stale beer – subtle scents picked up most likely by a trained nose.Ī more common disease with a trademark odor is diabetes, which is described as having notes of rotten apples, caused by low concentrations of acetone released on the breath. “On average, people smell more aversive when they’re sick,” Olsson said. “Some diseases result in a characteristic odor emanating from different sources on the body of a sick individual,” said Mats Olsson, an experimental psychologist at the Karolinska Institute in Sweden.Ī person’s smell escapes not just from their skin but their breath, blood and urine and subtle differences reveal just how healthy they are. The smells pouring out from various parts of the body are unique to an individual, made up of select compounds that vary depending on age, diet, sex, metabolism … and health. ![]()
