A 2025 network meta-analysis from Harbin Sport University pooled 30 randomized trials involving 2,576 people with sleep disturbances and ranked yoga first for sleep quality, according to the report published in
Sleep and Biological Rhythms. The analysis assigned yoga a score of 82.1 on the surface under the cumulative ranking curve, or SUCRA, a statistical measure used to order treatments in network meta-analyses. Walking followed at 81.2 and resistance exercise at 66.3, researchers said.
The authors stated that the comparisons between yoga and walking, and between yoga and resistance exercise, were inconclusive. The finding leaves open the question of whether yoga's first-place ranking reflects a genuine advantage over walking or a difference too small and too uncertain to separate the two activities statistically.
The review adds to a growing but conflicting body of evidence on exercise and sleep. Other meta-analyses have produced different rankings, and the authors of the Harbin study urged caution in interpreting the results, citing limited studies and the characteristics of people with sleep disturbances.
Study Design and Main Findings
The analysis compared seven exercise types: yoga, walking, resistance exercise, combined aerobic and resistance training, dance, aerobic exercise, and traditional Chinese exercises such as tai chi and qigong, according to the
