A new study suggests that listening to music regularly may help protect the brain as people age. Published in the International Journal of Geriatric Psychiatry, the observational study examined data from more than 10,000 older adults. Researchers looked at how music-related leisure activities affect cognitive function over time.
The study found that people who consistently listened to music had a 39% lower chance of developing dementia compared with those who rarely listened. The same group also showed 17% lower rates of cognitive impairment, a condition marked by a decline in thinking and memory that goes beyond normal aging but does not interfere with daily life. In addition, these individuals had higher overall cognitive scores and better episodic memory, which is the ability to recall everyday events such as conversations or appointments.
How music affects the brain
Earlier research has already linked music to improvements in mood, attention and memory. Listening to music has been shown to reduce stress hormones, lower anxiety and improve sleep quality, all of which contribute to long-term cognitive health. Familiar songs in particular activate memory centers in the brain and help strengthen neural connections.
Rhythmic music also improves coordination, gait and motor timing, which is why it is often used in physical rehabilitation. This physical engagement may add to the brain-protective effects. Music stimulates many parts of the brain at once, including areas involved in emotion, memory, attention and movement. This broad activation may help preserve neural flexibility, the brain’s ability to adapt and reorganize over time. That flexibility is considered a key part of healthy aging.
Simple ways to include music in daily life
The study focused on simply listening to music, not on playing an instrument or attending concerts. Researchers noted that people who made music a regular part of their daily routines saw the greatest cognitive benefits. Playing favorite songs during morning routines, while cooking, driving or walking were all linked to better outcomes.
Moderate volume is recommended. Chronic exposure to loud music can damage hearing, and hearing loss is a known risk factor for cognitive decline. A good rule is to keep the volume low enough to hold a conversation without raising the voice.
Active listening, such as singing along, tapping rhythms or dancing, adds sensory and motor involvement that may boost cognitive stimulation beyond passive listening. However, music is not a standalone solution. It works best alongside other brain-healthy habits such as good sleep, social connection, physical activity and a nutrient-rich diet.
While the study does not prove that music directly causes a lower risk of dementia, it adds to a growing body of evidence that small, consistent habits can shape well-being as people age.
