Researchers at the University of Chicago found 39% of subjects who failed olfactory sense tests died within a five-year period, compared with 19% of subjects with moderate smell loss and just 10% who retained a healthy sense of smell. This mean the loss or degradation of the olfactory sense may serve effectively as an “early warning” signal that something has gone very wrong inside the body, says the study published in the journal _PLOS One_ on Wednesday. “We think loss of the sense of smell is like the canary in the coal mine,” said the study’s lead author Dr. Jayant Pinto. “Our findings could provide a useful clinical test, a quick and inexpensive way to identify patients most at risk.” The research was conducted in two waves over the course of more than five years and surveyed approximately 3,000 adults. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3455141/study-sense-of-smell-death/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3455141/study-sense-of-smell-death/"},"headline":"How Your Sense of Smell Is Linked to Your Lifespan","datePublished":"2014-10-02T08:10:56.000Z","dateModified":"2026-02-21T10:32:18.002Z","description":"Older adults who suffer an impaired olfactory sense are more likely to die within five years, say researchers","url":"https://time.com/3455141/study-sense-of-smell-death/","keywords":["Research","Death","study","health"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdf3f90fdcd2b2043/6986a6b61eebf79ddc37303d/smell-life.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"David Stout","jobTitle":null,"url":"https://time.com/author/david-stout/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltdf3f90fdcd2b2043/6986a6b61eebf79ddc37303d/smell-life.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Womans jaw, low angle","caption":"Womans jaw, low angle","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/research/","name":"Research"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3455141/study-sense-of-smell-death/","name":"How Your Sense of Smell Is Linked to Your Lifespan"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"A 100-Year-Old Sex Therapist on Having Good Sex, Then and Now","description":"A practicing sex therapist in New York City, Dr. Shirley Zussman has witnessed everything from the legalization of the contraceptive birth control pill to the AIDs epidemic in the 1980s to the rise of internet porn in the new millenium.","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/uJFYIrvP/poster.jpg?width=720","uploadDate":"2014-08-20T13:40:15.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/uJFYIrvP.m3u8","embedUrl":"https://time.com/3455141/study-sense-of-smell-death/","duration":"PT3M13S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/3455141/study-sense-of-smell-death/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
