- A 2025 review from Beijing University of Chinese Medicine analyzed 22 trials and found that yoga, Tai Chi and walking/jogging can improve sleep quality as effectively as medication or therapy, without side effects like dependence or next-day drowsiness.
- Yoga added about 110 minutes of sleep per night, improved sleep efficiency by nearly 15%, reduced time to fall asleep by 30 minutes and decreased nighttime wakefulness—rivaling prescription medications without chemical dependency.
- Tai Chi improved all sleep outcomes (over 50 extra minutes of sleep, 25 minutes faster to fall asleep, fewer awakenings), with benefits persisting for up to two years, likely due to activating the parasympathetic nervous system and reducing physiological hyperarousal.
- These aerobic activities lowered insomnia severity scores by nearly 10 points, improved daytime functioning and mental clarity by increasing energy expenditure, lowering cortisol and boosting melatonin production.
- Strength training did not improve sleep in this analysis, challenging assumptions that all vigorous activity helps. However, nearly 70% of reviewed trials had design flaws, so experts recommend pairing gentle exercise with cognitive behavioral therapy for best results.
For millions of Americans who have spent sleepless nights watching the clock crawl toward dawn, a new scientific analysis offers hope that doesn't come in a pill bottle. A comprehensive review published in 2025 by researchers at the Beijing University of Chinese Medicine has found that certain forms of gentle exercise can improve sleep quality as effectively as medication or therapy for people with insomnia.
Led by researcher Zhijun Bu, the systematic review analyzed 22 randomized controlled trials involving 1,348 participants across multiple countries. The study compared seven different exercise interventions against usual care or lifestyle modifications to determine which activities most effectively combat insomnia. The findings, published in a peer-reviewed medical journal, identified three standout exercises: yoga, Tai Chi and walking or jogging.
"Insomnia is generally defined as having difficulty falling asleep or experiencing frequent or early awakening," said BrightU.AI's Enoch. "The three most common causes of insomnia are depression, anxiety and stress. Insomnia can be classified into three types: sleep-onset insomnia, sleep-maintenance insomnia and early-morning-awakening insomnia."
Why this research matters now
The significance of this study extends beyond its immediate findings. With an estimated 30% of adults worldwide experiencing some form of insomnia and prescription sleep medications carrying risks of dependence, next-day drowsiness and cognitive impairment, accessible non-pharmaceutical alternatives have become increasingly urgent. The opioid crisis and growing awareness of medication side effects have pushed both patients and physicians to seek safer long-term solutions.
Historically, exercise has been recommended for general health but rarely prescribed specifically for sleep disorders. This research changes that paradigm, offering evidence that the type of exercise matters more than simply staying active. The findings arrive at a time when digital screens, chronic stress and irregular schedules have made restorative sleep increasingly elusive for modern populations.
Yoga: Nearly two extra hours of sleep
According to the analysis, yoga added nearly two hours to total sleep time, with participants sleeping approximately 110 minutes longer on average. Sleep efficiency improved by nearly 15%, meaning individuals spent a greater proportion of their time in bed actually sleeping rather than lying awake.
The practice also reduced the time required to fall asleep by about 30 minutes and decreased wakefulness after initially drifting off. These improvements rival those seen with prescription sleep medications but without the chemical dependency or side effects.
The mechanisms behind yoga's effectiveness appear multifaceted. The combination of body awareness, controlled breathing and mindful focus helps calm the overactive brain activity that often prevents sleep onset. Regular practice reduces anxiety and physiological arousal, two primary drivers of chronic insomnia.
Walking or jogging: Daytime energy and mental clarity
For individuals whose insomnia manifests primarily as daytime fatigue, brain fog and poor concentration, walking or jogging proved most effective. These aerobic activities reduced insomnia severity scores by nearly 10 points on standardized measurement scales, a clinically meaningful improvement that translates into better daytime functioning.
The researchers noted that walking and jogging help by increasing energy expenditure, lowering stress hormones like cortisol, boosting melatonin production and encouraging deeper sleep stages. Unlike high-intensity workouts that can overstimulate the nervous system, moderate-paced walking or jogging appears to regulate the body's sleep-wake cycle without triggering the stress response that interferes with rest.
Tai chi: The star performer with lasting benefits
Tai Chi distinguished itself as the most consistently effective exercise across all measured sleep outcomes. This slow, meditative martial art improved sleep quality, duration and efficiency simultaneously. Participants experienced over 50 minutes of additional sleep per night, fell asleep about 25 minutes faster and experienced fewer nighttime awakenings.
The science behind Tai Chi's sleep benefits extends beyond simple relaxation. The practice activates the parasympathetic nervous system, often called the rest and digest system, directly counteracting the physiological hyperarousal that characterizes insomnia. Long-term practice may also reduce inflammation, boost brain-derived neurotrophic factor, a protein essential for neural health and support healthy circadian rhythms.
What didn't work: Strength training's surprising results
The finding challenges assumptions that any vigorous physical activity improves sleep and underscores the importance of matching exercise type to sleep problems.
For individuals who wake frequently during the night, yoga or Tai Chi may provide the greatest benefit. Those struggling with daytime fatigue and difficulty concentrating should consider adding walking or jogging to their routines.
For combined short-term and long-term insomnia relief, Tai Chi appears to offer the most comprehensive and durable improvements. The researchers emphasized that even 20 to 30 minutes of these activities several times per week could produce meaningful sleep benefits.
Cautions and considerations
Experts also recommend pairing regular moderate exercise with cognitive behavioral therapy for insomnia, which remains the gold standard non-pharmaceutical treatment. Individuals should avoid intense workouts within two hours of bedtime, as vigorous exercise can temporarily elevate heart rate and body temperature, interfering with sleep onset.
This research makes one thing clear: gentle, accessible forms of exercise can serve as powerful sleep medicine. Whether rolling out a yoga mat, joining a Tai Chi class in the park or adding brisk evening walks to the weekly routine, individuals struggling with insomnia have evidence-based alternatives to sleeping pills. The practice of moving the body with intention and awareness does more than improve fitness; it trains the body to rest.
