Many people find death to be a strange and often scary subject. People have tried to understand and plan for the end of life for a very long time. Surprisingly, some scientific research says that our sense of smell may be the key to understanding what it means to be close to death. It seems that our noses can give us strange signs about when people may die. We can smell when someone else is about to die, and losing our sense of smell can tell us a lot about our own health in the future.
Getting the Smell of Death: A Sixth Sense?

One interesting thing about our sense of smell is that it can tell when someone is about to die. Many unconfirmed reports have been made public about people who said they smelled something before a loved one died. These events give us hints that there is a hidden sixth sense that is connected to our sense of smell.
A number of theories try to understand this event. One theory is that as the body gets closer to death, it releases chemicals or smells that most people can’t smell but some people with very good senses of smell can. Another idea is that our sense of smell might be connected to small changes in our emotions, which could help us tell when someone we love is going to die soon. We don’t really know that we are smelling death; our scent glands start to tell us that it is close. (1)
There isn’t a lot of scientific proof in this area, and there haven’t been many interesting studies done. Scientists at the University of Chicago found in one study that animals, like dogs and cats, can tell when someone has certain illnesses, like cancer. In the same way, people who have a strong sense of smell might also be able to tell when someone is about to die. It has been shown that animals that live in hospitals and long-term care facilities can almost always tell when a patient or resident is going to die. (2, 3)
Loss of Smell: A Sign of Poor Health in the Future
Along with being able to tell when someone is about to die by their smell, losing your own sense of smell may also be a sign of your future health. Several scientific studies have shown that a loss of the ability to smell may be linked to some health problems, such as neurological diseases like Alzheimer’s and Parkinson’s. It can also be a sign of trouble with the lungs or heart. (4)
Researchers have found that the sense of smell often gets worse before other signs of these diseases show up. This means that losing the ability to smell could be an early warning sign that helps people and medical workers spot possible health problems and act quickly.
A study in the Journal of the American Geriatrics Society actually found that older people who had trouble with their sense of smell were more likely to die within five years than older people who had a good sense of smell. This means that losing the ability to smell could be a good way to tell about your overall health and risk of death, giving us useful information and chances to help avoid illness.
The Future of Making Predictions Based on Smell

We are learning more about how different parts of the body work together and how they are connected as our knowledge of the body grows. People often don’t pay as much attention to their sense of smell as they do to their sight and hearing, but it seems to have a lot of promise when it comes to figuring out when someone is going to die and what will happen with their health in the future. These interesting results need to be confirmed by more study. Scientists are looking into the chemical changes that happen in the body before death and how problems with smell can affect health and the risk of death. If we learn more about this topic, we might be able to make testing tools that use the power of smell to help people get help quickly, which could save their lives.
Does the nose know?

It’s interesting to look into the idea that “the body knows when death is near, and it starts in your nose.” Being able to smell death in other people and losing your sense of smell as a sign of future health opens up new areas of study and research in medicine and human biology. By studying and using the power of our sense of smell, we might learn important things about life and death that will make our lives better in the long run.
