Tai chi for anxiety, depression and stress in college students: what 12 trials found

A 2026 review of 12 trials in 1,057 college students found tai chi eased depression and stress. Anxiety and sleep results were less certain.

Published October 2026

Short answer

Tai chi eased depression and stress in college students, with moderate-certainty evidence. Anxiety and sleep results were less reliable because trials varied widely. Evidence grade B (Moderate). Meta-analysis of randomised trials (8 trials, 734 students for depression); downgraded once for risk of bias, since tai chi trials cannot be blinded and many reported methods poorly.

Key takeaways

  • Across 8 trials with 734 students, tai chi reduced depression symptoms (SMD -0.67, 95% CI -0.90 to -0.43) compared with usual activity or conventional exercise, with moderate certainty [1].
  • Perceived stress fell too (SMD -0.40, 95% CI -0.65 to -0.14) across 3 trials with 342 students, with consistent results and moderate certainty [1].
  • Anxiety also fell (SMD -0.79, 95% CI -1.42 to -0.15), but results varied widely between 8 trials (I2 92%), so certainty was low [1].
  • Sleep quality improved in 3 trials, but certainty was very low because results differed so much (I2 97%) [1], and an earlier review found no significant sleep gain in normal college students [2].
  • A 2023 review of 23 studies (4,370 people) found smaller effects when tai chi was compared with other exercise: anxiety d 0.28 and depression d 0.20 [3].

What the study did

University is a stressful stage of life, and exercise-based approaches that are low-cost and easy to learn have drawn interest [1]. This 2026 systematic review searched eight English and Chinese databases up to 1 February 2026 for randomised trials of tai chi in college students. It found 12 trials with 1,057 students (554 doing tai chi, 503 in comparison groups), and pooled the results [1]. The tai chi styles were 24-form, Yang-style and Bafa Wubu, practised for 8 to 18 weeks, and comparison groups did conventional exercise or their usual activities [1].

What it found

Depression symptoms were lower after tai chi (SMD -0.67, 95% CI -0.90 to -0.43) in 8 trials with 734 students, with moderate certainty [1]. Perceived stress was lower (SMD -0.40, 95% CI -0.65 to -0.14) in 3 trials with 342 students, with consistent results [1]. Anxiety fell by SMD -0.79 (95% CI -1.42 to -0.15), but the 8 trials disagreed a lot (I2 92%), so the certainty was low [1]. Sleep scores improved by 2.14 points (95% CI -4.13 to -0.15) in 3 trials with very low certainty [1]. Subgroup analyses hinted that frequency and duration might matter, but the differences were not statistically significant, so no best dose could be identified [1].

How it fits

A 2023 review of 23 trials (4,370 people, mostly general populations) found that tai chi beat non-mindful exercise by a smaller margin: anxiety d 0.28 and depression d 0.20 [3]. Part of the gap may be the comparison: the student trials compared tai chi with conventional exercise or usual activities, not only with other exercise [1]. An older review of traditional Chinese exercise found it improved sleep in several groups, but not in normal college students [2]. See the Tai Chi page for the evidence on falls, knee pain and blood pressure.

Limits

Only 3 trials covered stress or sleep, and fewer than 10 trials were available for any outcome, so the authors could not test for publication bias [1]. Some trials gave too little detail on randomisation, allocation concealment and blinding, and tai chi programmes differed in style, frequency and length [1]. Students knew they were doing tai chi, so expectations may have shaped self-reported mood. The authors call for larger, better-run trials with long-term follow-up [1]. This is not medical advice: students with persistent low mood or anxiety should speak to a doctor or campus counselling service.
