TEDxObserver - Peter Lovatt - Psychologist and dancer

Summary

Peter Lovatt explores how dance may affect the body and mind, with particular attention to its potential benefits for people with Parkinson’s disease.

Parkinson’s disease and dance

Parkinson’s disease can affect balance, walking, mood, and anxiety. Lovatt describes earlier studies in which recreational dance was associated with improvements in balance and walking.

In two studies at the University of Hertfordshire, participants with Parkinson’s were assessed and then attended roughly a dozen dance classes. The classes included varied styles, such as contact improvisation, cheerleading, and Bollywood dance. One study used movement without a regular beat; the other emphasized dancing to the beat over ten weeks.

Reported outcomes

The studies found improvements in participants’ physical abilities, including balance and walking, as well as in quality of life and mood. Physical discomfort and anxiety decreased, while vigor increased. Lovatt says the research was still exploring why dance might produce these benefits.

Three elements of dance that may support health

1. Social interaction: Dance involves engaging with other people. Lovatt cites a study of about 5,000 people in which greater social engagement was associated with a lower likelihood of developing dementia during follow-up three to five years later. This is an association, not proof that social activity prevents dementia.

2. Physical activity: Lovatt describes a study of 120 people: one group exercised three times a week for a year, while another did stretching. The stretching group’s hippocampus continued to shrink, while the exercise group’s hippocampus reportedly grew by 1–2%, as measured by fMRI. The hippocampus is linked to memory, so the result suggests exercise may help support memory-related brain structures.

3. Cognitive challenge: Learning dance steps draws on memory, spatial awareness, and problem-solving. Lovatt says cognitive-training studies report improvements in problem-solving and increased brain activity during scans, possibly indicating that more brain areas support the task.

Overall point

Dance combines social, physical, and cognitive activity. Lovatt suggests that including all three—especially physical movement vigorous enough to raise the heart rate—may help explain dance’s potential health benefits.
