The Nose and Terminal Illness: A Curious Connection
Death is a puzzle, but studies suggest that our sense of smell may give subtle clues. Some people say they can smell a certain odor just before a person dies—perhaps related to chemical processes near the end of life. Animals can pick up on disease, and the same human abilities are being explored.

Loss of the sense of smell also predicts future illness, such as Parkinson’s, Alzheimer’s, and heart disease. Researchers discover that people with compromised odor are at increased risk of death.

As life fades in the later years, people experience fatigue, loss of appetite, confusion, and shortness of breath. Comforting interventions—light touch, soothing music, and tranquil environment—can support calm.

Caregivers must also take care of themselves. The psychological and physical toll is real, and assistance is required.

Ultimately, end-of-life caregiving is respecting dignity, showering with love, and creating moments of meaning that transcend loss.
