High-intensity workouts offer the strongest sleep benefits for older adults with cognitive impairment

A Texas A&M study using Oura Rings found that both light and vigorous exercise reduce sleep disturbances in older adults with mild cognitive impairment, with high-intensity workouts providing the greatest benefit; moderate activity had little to no significant effect. The small 14-day study of seven participants suggests tailored group exercise could improve sleep and quality of life, though larger studies are needed.
