A sweeping meta-analysis of 30 randomized controlled trials suggests that high-intensity yoga may be the most effective exercise for improving sleep quality. Researchers from Harbin Sport University examined data from over 2,500 participants across the globe with sleep disturbances. They found that practicing high-intensity yoga for less than 30 minutes, twice a week, led to the biggest sleep improvements—outperforming walking, resistance training, aerobic workouts, and traditional Chinese exercises like tai chi. While walking and resistance training also showed positive results, yoga’s unique blend of muscle work, heart rate elevation, and breath control may help activate the parasympathetic nervous system, encouraging rest and deeper sleep. The study authors caution that individual results may vary, and more research comparing specific exercises is needed.
