For every disease and condition, there are signs and symptoms that help you figure out that something is wrong. Apparently, a sign of early deaths is losing the sense of smell. A new research focused on people in their 40s and 50s who lost their sense of smell.
This study was conducted by a team of Swedish researchers. The scientists observed that people older than 40 who had a poor sense of smell were more likely to die in the next 10 years. The risk for these people was 20% bigger when compared to people the same age that had a normal sense of smell.
“The sense of smell seems to be a good indicator of aging brain health. We see smell function as the ‘canary in the coal mine,” mentioned Jonas Olofsson, co-author of the study
Despite the fact that dementia was linked to the loss of smell in previous studies, there is no link between dementia and early death. Researchers who conducted this new study mentioned that there must be another explanation for which the loss of smell might predict early death.
In order to conduct this study, researchers analyzed 1,800 people who were aged between 40 and 90. They monitored these people for more than a decade. The researchers carried out smell tests. They also tested their health conditions and mental decline.
The study showed a link between the loss of smell and early death. Unfortunately, scientists were not able to provide the reason for which these two are linked. They did not find a cause-and-effect correlation. The research showed the same link even after scientists took into consideration factors like health status, mental functioning, and education levels.
The way in which they tested the participants’ sense of smell was very interesting. There were 13 odors and people had to choose between 4 possible answers for each one. This is how the researchers figured out if the participants had a good or bad sense of smell.
The researchers mentioned that there is a way to improve your smell. Any sense can be “trained”. In order to regain this sense, you can smell odors at least twice a day. This way, your nose will start to get better at sniffing different odors.
