Growing evidence shows that dancing can boost brain health and help manage neurocognitive (神经认知的) disorders. So what is it about dance that's different from other regular exercises?
Helena Blumen, a cognitive (认知的) scientist at Albert Einstein College of Medicine, says the complex (复杂的) mental multitasking that dance requires involves various parts of the brain at the same time. Basically, dancing requires more brain power than simpler repetitive (重复的) exercises.
While scientists are still learning how the mechanisms of dancing work in the brain, a clearer picture is beginning to appear. Researchers at Otto von Guericke University in Magdeburg, Germany, did MRI scans of older adults who had participated in one of two programs over a six -month period. One group practiced dance and the other did a traditional exercise program with cycling and strength training. While both groups improved their level of physical fitness, the dancers grew more white and gray matter in the parts of the brain responsible for cognitive processes. Both white and gray matter typically decline as we get older, making communication in the brain slow.
Imagine your brain is a city with loads of roads. The researchers assume the changes brought by dancing contribute to brain plasticity, which is like the city's ability to build new roads, repair old ones or even change the direction of traffic based on how often the routes are used and what the city needs.
In addition to the physical and neurological (神经学的) benefits, dance can also help people accept what their bodies can and can't do. Dawnia Baynes, 44, developed multiple sclerosis (MS) after her body lose all feeling from the chest down. She recently joined an online dance program for people with MS. Not only has it improved her range of motion, it has also helped her overcome her fear of being judged for how she moves.
"To see other people moving is like I'm moving," she says, "and knowing that I don't have to be professional and super technical in my dancing makes me comfortable with where I am right now."
