Researchers studied older adults with mild cognitive impairment to see which exercise helps sleep. They used Oura Rings at a long-term care facility to record activity and sleep for two weeks. The team classified movement as light, moderate, or vigorous.
They found that vigorous, high-intensity exercise gave the largest improvement in sleep. Light activity helped a little, but moderate exercise did not show a clear effect in this small study. The authors said the sample was small and did not list exact activity types. They suggested simple programs like group walking clubs or swimming lessons to help these older adults.
