What causes Aging changes in the senses?
Last updated September 7, 2026.
**Aging changes your senses because sensory tissues and nerves gradually change how they detect and transmit information.** Your eye lenses become less flexible, making close focusing harder, while changes in your inner ear can reduce hearing. Changes in taste buds, smell receptors, and nerve function can affect flavor and touch. Your genes, noise exposure, smoking, medicines, and conditions such as diabetes also influence these changes. Hearing protection, better lighting, and eye and hearing exams help you protect function and identify treatable problems.
What to do
- **Get changes checked:** Ask a clinician to assess persistent changes that affect your daily activities.
- **Review medicines:** Ask your clinician or pharmacist whether your medicines affect your senses before making any changes.
- **Protect your hearing:** Use earplugs or earmuffs around loud equipment and lower headphone volume.
- **Improve lighting:** Add lighting for reading and walking while reducing glare.
- **Check water temperature:** Keep your water heater at no higher than 120°F to reduce burns when temperature sensation is reduced.
- **Act on sudden loss:** Seek immediate medical care if you suddenly lose hearing or vision.
