Discover the essential role of your five senses and how to preserve them as you age.

Our senses are our guides from birth to the end of life.

From the moment you wake up, your senses guide you: the light flooding the room, the smell of coffee, the beep of your alarm. Far more than “simple sensors,”

Your five senses are your allies for orientation, memory, safety, and pleasure. 

They fuel attention, support cognition, and weave your connection to the world—from birth to life’s end.

Key takeaway: caring for your senses also protects your memory, balance, and independence.

1) Hearing – Connect, understand, protect yourself

Key role: understanding speech, catching conversational nuances, enjoying music… and detecting danger (horns, alarms).

Warning signs with age: difficulty following group conversations, turning the TV volume up, fatigue after social exchanges.To preserve:

• Limit exposure to loud noise; take auditory breaks.

• Get regular hearing checks; consider assistive devices if needed.

• Practice active listening: close your eyes for 30 sec and identify 3 sounds.

Mini-exercise: the “sound scan” — notice one nearby sound, one mid-range, and one distant.

2) Touch – Ground, orient, feel

Key role: informing you about temperature, pain, textures; contributing to proprioception (body position).

Warning signs: reduced sensitivity in extremities, clumsiness, decreased motor ease.To preserve:

• Vary textures (gardening, bread dough, fabrics).

• Stimulate proprioception: walk barefoot at home for a few minutes; feel the pressure under your feet.

• Keep skin hydrated; check shoe fit.

Mini-exercise: “texture box” — describe an object with eyes closed (rough, smooth, warm…).

3) Vision – Orient, decode, remember

Key role: detecting contrast, colors, movement; supporting reading, navigation, face recognition.

Warning signs: needing more light, nighttime discomfort, glare sensitivity, trouble distinguishing contrasts.To preserve:

• Ensure adequate lighting (task lamps, nightlights in hallways).

• Up-to-date glasses; regular eye exams.

• Eat antioxidant-rich foods (leafy greens, colorful fruits).

Mini-exercise: the “mental photo” — gaze at a scene for 10 sec, then describe it (shapes, colors, landmarks).

4) Taste – Nourish, motivate, enjoy

Key role: guiding food choices, signaling spoilage, supporting appetite and the joy of eating.

Warning signs: decreased appetite, “flat” taste, less interest in meals.To preserve:

• Vary flavors/spices (umami, fresh herbs); play with textures.

• Stay well-hydrated; maintain good oral hygiene.

• Pair meals with social pleasure (share, tell a recipe story).

Mini-exercise: “5 tastes, 5 words” — during a meal, name: taste, texture, temperature, memory, emotion.

5) Smell – Remember, savor, protect

Key role: triggering emotional memories, enriching the flavor of food, signaling danger (smoke, gas).Warning signs: diminished perception of odors, muted flavors.To preserve:

• Create a “scent library”: citrus, coffee, spices, garden herbs.

• Air out rooms daily; walk outside to oxygenate and diversify smells.

• Check smoke/gas detectors (safety).

Mini-exercise: “olfactory memory” — smell a spice and tell the memory it evokes.

Bonus: Balance & movement (vestibular system & proprioception)

Key role: stability, fall prevention, focused attention.To do:

• Balance exercises (single-leg stance near a support, tai chi, mindful walking).

• Posture: align head-shoulders-pelvis; breathe slowly.

• Barefoot routine 2–3 min/day to “wake up” receptors in the soles.

Falls are often linked to reduced proprioceptive/vestibular input and scattered attention. Moving regularly and being aware of your base of support protects balance… and attention.

Cross-cutting habits that protect all senses

• Light & air: get daylight exposure; air out for 10 minutes.

• Sleep: keep regular hours; limit screens in the evening.

• Hydration & nutrition: water, herbal teas; colorful vegetables, fatty fish, nuts.

• Medications: have your prescriptions reviewed (some affect taste/smell/balance).

• Regular checkups: vision, hearing, oral health—and podiatry if needed.

• Social & joy: conversation, music, shared cooking — joy stimulates the brain.

3-minute sensory ritual

1. Breathe 6 slow cycles (in through the nose, out through the nose).

2. Choose one sense and activate it (listen for 3 sounds / notice 3 details / smell 1 scent).

3. Name one word for what you feel (calm, energized, curious…).

If a sense declines

The brain adapts—other senses take the lead. With tools (glasses, hearing aids, lighting, home modifications) and compassionate support, it’s possible to keep exploring and enjoying the world. For people living with neurocognitive disorders, the Snoezelen approach offers a gentle way to rediscover the senses (soft lights, music, textures, scents, reassuring touch).

Conclusion

Your senses aren’t just windows on the world—they are your guides.Protecting them preserves your attention, memory, balance—and your joy of living.Every small sensory gesture counts. Which one will you choose today?
