The 19th-century Danish author Hans Christian Andersen once wrote, “Where words fail, music speaks.” Today, science is backing that idea — showing music doesn’t just move us emotionally, but may also benefit brain health.

Mental health experts say music can influence mood, reduce stress, and even sharpen memory and cognitive function.

“Listening to your favorite music actually activates the natural opioid system in your brain,” Dr. Gary Small, director of behavioral health breakthrough therapies at Hackensack Meridian Health, told Newsmax’s “National Report.”

“That’s the area that controls feelings of pleasure and relieves pain sensations,” Small explained.

Music also stimulates the brain’s limbic system, which plays a key role in emotional regulation. That’s why a familiar song can instantly transport you back in time.

“It’s very powerful,” said Small, who is also editor of Dr. Gary Small’s Mind Health Report. “Often they’re fond memories, and it brings you right back there and it boosts your mood.”

Even when the memories aren’t entirely positive, the connection between music and recall highlights how deeply songs are tied to the brain’s memory centers.

Beyond nostalgia, music may also help keep the mind sharp — especially for older adults.

“Scientists have found that older individuals who practice playing a musical instrument actually improve their memory and cognitive function,” Small said. “It may be that reading music while you're playing an instrument develops the brain’s multitasking abilities and problem-solving skills.”

For those who don’t play an instrument, simply listening can still offer benefits. And variety may be key.

“We know our brains like variety,” Small noted. “Even if you have a favorite genre, think about changing it up. That could pique your interest.”

Music may also be a powerful learning tool. Many people find it easier to remember song lyrics than everyday information — a concept educators have used to help students retain material.

“That’s a clever way to integrate what kids need to learn and link it to their favorite music,” Small said.

As for whether older adults should try to keep up with newer music trends, Small says it’s optional — but potentially beneficial.

“It doesn’t really matter because if that’s not your thing, don’t push yourself,” he said. “However, I think it’s a good idea to give it a try. There may be some aspects of that genre that you really enjoy, and it can bring the generations closer together.”
