While mental exercises like puzzles and memory games get most of the attention for brain health, new research highlights an unexpected activity that outperforms nearly every other form of exercise in protecting against cognitive decline.
Dancing more than once a week reduced dementia risk by 76 percent compared to those who rarely danced or didn't dance at all, according to research published in the New England Journal of Medicine in 2003. The landmark study tracked 469 adults over age 75 for more than five years, examining how various leisure activities affected dementia risk.
Dr. Trisha Pasricha, an assistant professor of medicine at Harvard Medical School, recently highlighted these findings in a December 2025 video for The Washington Post. Dancing stood out as the only physical activity in the study that showed protective effects against dementia, while activities like swimming, cycling, and tennis showed no significant impact on cognitive decline.
The study found that mental activities like reading and playing board games also reduced dementia risk, but dancing uniquely combined both cognitive and physical benefits. The activity requires simultaneous coordination of movement, music, and often social interaction with a partner.
Why dancing works differently
The cognitive demands of dancing set it apart from other forms of exercise. Dancers must make constant split-second decisions about movement, synchronize steps with music rhythm, and coordinate with partners if dancing socially.
This combination activates multiple brain regions simultaneously. Unlike activities with repetitive movements or memorized sequences, freestyle social dancing forces the brain to process new information and make rapid adjustments continuously.
Research published in Frontiers in Psychology in January 2025 examined how dance interventions affect people with dementia and mild cognitive impairment. The study emphasized that dance serves as an "embodied prevention strategy" by activating motor, sensory, cognitive, and social processes simultaneously.
Additional health benefits beyond the brain
The cardiovascular advantages of dancing extend well beyond cognitive protection. Regular dancing strengthens the heart muscle and improves blood vessel function, according to research published in Heart and Mind in January 2025.
Cleveland Clinic physical therapist Kellie Grabfelder explained in April 2024 that dancing increases heart rate and blood flow while improving strength, mobility, flexibility, and balance. The activity can burn up to 300 calories per half-hour depending on intensity and body weight.
Dancing also releases endorphins that improve mood and reduce stress. A systematic review published in 2023 found that dance movement interventions showed large positive effects on social connectedness and integration among older adults, which may help combat social isolation.
What's next
The protective effect of dancing against dementia appears strongest for styles that require improvisation and partner coordination rather than memorized routines. Community centers, dance studios, and senior centers across the country offer beginner classes in styles ranging from ballroom and salsa to line dancing and swing.
For those preferring to dance at home, online video tutorials provide accessible options for getting started. The key is consistency, with researchers noting the greatest cognitive benefits came from dancing more than once per week rather than occasional participation.
