May cause joy: The full-spectrum health benefits of dance
When musician David Byrne, the founder of , performed at the sold-out Dolby Theatre in Los Angeles last fall, the entire crowd was on its feet for almost the entire show. They danced enthusiastically for nearly two hours straight, feeling a kind of unfiltered joy that鈥檚 rare to access in everyday life.
The experience was a reminder of a long-dormant love of dance. The following month brought a sign-up for 鈥淕roove Therapy鈥 with local dance teacher . The youngest in our group is 16, the oldest over 70. Every Saturday, the class plays out a verb each participant brings to class 鈥 release, gather, resist, invite 鈥 translating abstract intentions into motion. It sounds faintly ridiculous. It is also disarmingly effective. Within minutes, something shifts. Stress loosens. Then for the next hour, the group learns hip-hop shuffles and swings their hips to Kool & the Gang or Beyonc茅. The class ends with the same feeling each time: exhausted and exhilarated.
The dance classes provoked such a profound shift in mood as well as in the body that it was worth finding out if there was more to it.
is now increasingly suggesting that dance is medicine, a deeply effective intervention for physical, cognitive, and emotional health.鈥 Behind the feel-good performance lies hard science. On a purely physical level, dance improves cardiovascular fitness, strength, and coordination. In a longitudinal , seniors who took part in regular dance training fell less often and were described as 鈥減hysically better off and mentally fitter鈥 than those in the control group.
Though the body benefits are impressive, the neurological ones are what make scientists lean forward. Dancing activates a wide network: auditory pathways, visual and motor cortex, the amygdala, and, above all, the somatosensory cortex and networks that keep track of where your body is in space. Each change in rhythm or melody is processed in milliseconds and translated into new steps, adjustments, and expressions, a form of real-time 鈥渕ultitasking鈥 that pushes the brain harder than many other sports.鈥
Nobody understands this better than the dozen people who gather for David Leventhal鈥檚 class at a dance studio in Brooklyn. Though it鈥檚 cold outside, Leventhal is conjuring a beach. 鈥淰isualize what that warmth feels like,鈥 he says, brushing his hands over his arms as if applying sunscreen. 鈥淐an we take those waves in different directions, just like they do in the ocean?鈥 Around him, a dozen bodies begin to ripple to the tune of the pianist in the room. Arms slice, float and curl through the air. For a moment, the bare white room is less clinic than coastline.
Leventhal, who danced for 13 years with the Mark Morris Dance Group, has spent the last quarter century leading a different kind of choreography: Dance for PD, a program for people living with Parkinson鈥檚 disease.
What began in Brooklyn in 2001 now reaches more than 30 countries and roughly 500 communities. Across the room, people who arrived with their shoulders slightly caved inward now stand taller. They trace arcs through space, step through a tango phrase, and turn what might otherwise register as tremor into jazz hands.
Participants in the , which was created by the Mark Morris Dance Group and the Brooklyn Parkinson Group, routinely report better balance, more confidence walking, and a renewed sense of self. But just as often, they mention something less clinical and more essential: joy.
鈥淚 sometimes cannot walk, but I can dance,鈥 participant Cyndy Gilbertson said in the documentary . 鈥淭he music leads, in other words; it鈥檚 not my brain telling me to take a step.鈥
You don鈥檛 need a severe diagnosis to benefit from dance. 鈥淒ance has been part of our human culture for millennia,鈥 Leventhal points out. 鈥淚t鈥檚 how we communicate, how we express emotion, how we find each other, how we build community.鈥 Across cultures, from Indigenous North American traditions to M膩ori and Pacific Islander practices, dance has also long been intertwined with healing.
Over time, this seems to change the brain鈥檚 structure. A that followed older adults in a dance program for more than a year reported increases in gray matter volume and synaptic density in regions important for memory and executive function, along with preserved over five years of follow-up. The researchers found that dancing appeared to build 鈥渃ognitive reserve鈥 and was 鈥渢he best prevention鈥 against age-related cognitive decline in their cohort, with dancers showing a statistically lower risk of dementia than nondancers.鈥
Those findings dovetail with a widely cited observational study: People who danced more than once a week had a risk of developing dementia than those who danced less often, an association reported as stronger than that seen with many popular 鈥渂rain games.鈥
鈥淚t鈥檚 a full-spectrum activity,鈥 Leventhal explains. 鈥淚t engages the body, cognition, emotion, and social connection 鈥 all supported by music.鈥
The real power, he argues, lies in the overlap. 鈥淭he benefits come from the synergy among those domains.鈥
That synergy matters especially for Parkinson鈥檚, which affects motor control, cognition, emotional expression and social engagement. Many people withdraw from public life as symptoms progress. 鈥淭he beauty of this art form,鈥 Leventhal says, 鈥渋s that it鈥檚 a full-spectrum intervention for a full-spectrum condition.鈥
In a large of 55 randomized controlled trials in Parkinson鈥檚 disease, dance emerged as the most effective of nine exercise interventions for improving balance in that analysis, outperforming even advanced rehabilitation technologies. Styles like tango, waltz and foxtrot have been shown to improve gait speed and reduce falls.
While there is no cure for Parkinson鈥檚, some early research suggests that dance can slow down the for some people. 鈥淚t鈥檚 early evidence,鈥 Leventhal says carefully. 鈥淏ut exercise may be one of the only disease-modifying approaches we have.鈥
鈥淥ur auditory cortex synchronizes with the motor cortex,鈥 Leventhal explains 鈥 a mechanism particularly relevant in Parkinson鈥檚, where internal rhythm is disrupted by dopamine loss. External rhythm can step in as a kind of substitute metronome. 鈥淚t creates a roadmap,鈥 Leventhal says. 鈥淪omeone described it as a red carpet rolling out in front of them.鈥 For people who struggle to initiate movement, that cue can be transformative, enhancing neuroplasticity 鈥 the brain鈥檚 ability to form new connections.
鈥淣ovelty is huge,鈥 Leventhal says. 鈥淣ew patterns, new music, new movement.鈥 But novelty alone isn鈥檛 enough. 鈥淲hen something is also meaningful to you 鈥 when it connects emotionally, that鈥檚 when the brain is really activated.鈥
Another, more practical advantage: People keep coming back. Some participants have been dancing with Leventhal for over 16 years. People are welcome at all stages of Parkinson鈥檚. Some arrive in a wheelchair, others have recently been diagnosed. 鈥淚f people can get to class, they stay,鈥 Leventhal says.
That kind of adherence is rare in exercise programs, especially for chronic conditions. The reason, again, circles back to neuroscience. Motivation is tied to dopamine, the very neurotransmitter depleted in Parkinson鈥檚. Apathy is common. Getting on a treadmill can feel like scaling a wall. Dance, by contrast, lowers the barrier.
鈥淭he combination of music, social interaction, and movement is highly motivating,鈥 Leventhal says. 鈥淪ome people come to see their friends and stay for the movement. Some come for the music.鈥
And one more factor he considers crucial: 鈥淲e don鈥檛 treat people as patients,鈥 he says. 鈥淵ou鈥檙e a dancer. You鈥檙e learning a craft.鈥
When we move rhythmically, stress hormones like adrenaline and cortisol decline while the brain鈥檚 own reward chemicals 鈥 endorphins, dopamine, serotonin 鈥 surge, a set of 鈥減leasure cycles鈥 documented by researchers at who studied how music and synchronized movement generate feelings of social bonding and euphoria.
For people living with , anxiety or trauma, dance offers something more subtle: a way back into the body. According to a , dance can be more effective in alleviating depressive symptoms than any other form of exercise. Where distress constricts expression, expands it.
Plenty of workouts happen with headphones and in isolation. Dance, by contrast, almost always involves connecting with others. Social neuroscientists have shown that moving in synchrony with others increases liking, trust, and willingness to help. 鈥淲e entrain to each other,鈥 Leventhal says. 鈥淎nd that raises empathy, connection.鈥
For people with Parkinson鈥檚, the stakes are higher than mood or fitness. The disease is the fastest-growing neurodegenerative condition in the world. By the time it is diagnosed, estimates suggest that roughly 70% of dopamine-producing cells are already lost.
Which makes timing critical. 鈥淲e want people to start earlier,鈥 Leventhal says 鈥 not just to maintain function, but to build skills and resilience before symptoms advance.
At the end of Leventhal鈥檚 class, the participants play an imaginary volleyball game, batting an invisible ball through the air. 鈥淲e won, you won, we all won!鈥 Leventhal cheers, and all arms lift in victory.
