The Link Between Smell and Death, and End – of – Life Care
Death is a complex and often discomforting topic. Interestingly, there’s some science suggesting our sense of smell might be linked to death. We may be able to smell when someone else is near death, and losing our own sense of smell could predict future health issues.
Smelling Death in Others
Some people claim to smell something before a loved one passes away. There are theories: as the body nears death, it might release chemicals some can detect, or our sense of smell could be tied to emotional shifts. Limited studies show animals can sense chemical changes in sick people, so humans with a sharp sense of smell might sense death too.
Loss of Smell and Future Health
Losing one’s sense of smell can signal health problems. Research indicates it may be related to neurodegenerative diseases like Parkinson’s and Alzheimer’s, as well as respiratory and cardiovascular issues. It can be an early warning sign, and a study found that elderly people with a poor sense of smell were more likely to die within five years.
The Future of Smell – Based Predictions
The olfactory system holds potential in predicting death and health. Scientists are researching chemical changes before death and how smell loss impacts health. This could lead to new diagnostic tools.
