A 45-day course of a standardized yoga routine changed how healthy adults scored on mood, sleep and short-term memory tests, and changed resting connectivity in several brain networks, in a randomized controlled trial published in Scientific Reports on November 9, 2026. The routine was the Common Yoga Protocol, the 45-minute sequence written for India's International Day of Yoga. A 30-minute home session built on its structure follows the findings.
What the trial measured
Researchers at a university in Pune, India, recruited 139 healthy, nonsmoking adults between 18 and 55 with no prior yoga practice and assigned them at random to 45 days of supervised group yoga (70 people) or to a waitlist (69 people) that received general advice to stay active and was offered the classes afterward. Sessions averaged 50 minutes. The study ran from October 2023 to January 2025 and was open label. Fourteen people dropped out, eleven from the yoga group. The primary outcome was mood on the Positive and Negative Affect Schedule. Secondary outcomes were a digit span test of short-term memory, the Digit Symbol Substitution Test of processing speed, the Pittsburgh Sleep Quality Index, and resting-state functional MRI in a subgroup of 50, of whom 43 completed both scans.
After 45 days the yoga group's positive affect score was about 4 points higher than the control group's and its negative affect score about 3.4 points lower, both after adjusting for baseline. Total digit span rose by about 1.1 points and forward digit span by about 0.84, while backward span and the symbol substitution test showed no difference between groups. Sleep quality scores improved by about 1.2 points on a scale where lower is better. In the imaging subgroup, connectivity shifted in the sensorimotor, cerebellar, language, salience and dorsal attention networks relative to controls. The work was funded by India's Central Council for Research in Yoga and Naturopathy, part of the Ministry of Ayush.
The authors name the limits. The control group did nothing comparable, so some of the gain may reflect joining a scheduled group activity rather than yoga itself. Participants knew their assignment, which can shape questionnaire answers. The imaging sample was small. Two serious adverse events occurred, both judged unrelated to the practice. The trial measured healthy adults over six and a half weeks; it did not test cognitive decline, dementia or how long any change lasts. One trial is one trial, and the connectivity findings describe a pattern, not a mechanism.
The structure the trial borrowed
The government protocol the trial followed allots its 45 minutes this way: a one-minute opening, 8 minutes of joint loosening (neck, shoulders, trunk, knees and ankles), 3 minutes of larger whole-body movements, 5 minutes of Surya Namaskar, 15 minutes of postures across standing, sitting, prone and supine groups, 1 optional minute of kapalabhati, 6 minutes of breathing practice (alternate-nostril, ujjayi and bhramari, three rounds each), 5 minutes of seated meditation and a one-minute close. The session below keeps that order and trims each block to 30 minutes. It is modeled on the kind of protocol the trial used; it is not the trial, and a shortened version has not been tested against the full one.
A 30-minute session on the same frame
Minutes 0 to 5, loosening. Standing. Neck: forward and back, side to side, half circle each way, 3 of each. Shoulder rolls, 5 each way. Trunk twists, 5 each side. Knee bends, 5. Ankle circles, 5 each foot. Nose breathing throughout.
Minutes 5 to 9, Surya Namaskar. Two slow rounds of the 12-position sequence, one leg leading each round, moving on the breath. Step out of any position that strains the wrists or low back.
Minutes 9 to 21, postures. Standing: Tadasana with arms overhead, 5 breaths; Katichakrasana (standing twist), 3 each side; Trikonasana, 5 breaths a side. Sitting: Bhadrasana (bound angle) 5 breaths; Vakrasana (seated twist) 5 breaths each side; Ushtrasana (camel) or a half version with hands on the low back, 3 to 5 breaths; Sasakasana (hare pose) 5 breaths. Prone: Bhujangasana (cobra) 3 rounds of 3 breaths; Makarasana (crocodile rest) 5 breaths; Dhanurasana (bow) or a single-leg version, 2 rounds of 3 breaths. Supine: Pavanamuktasana (knees to chest) 5 breaths; Matsyasana (fish) or a supported version on a folded blanket, 5 breaths; Viparita Karani (legs up with hips supported) 10 breaths in place of a shoulder stand; Shavasana 2 minutes.
Minutes 21 to 27, breathing. Sit tall. Kapalabhati is optional in the protocol and skipped here. Nadi shodhana (alternate-nostril breathing without breath holds), 6 rounds. Ujjayi, 6 slow breaths with a soft throat sound. Bhramari, 6 breaths with a hum on the exhale.
Minutes 27 to 30, meditation. Eyes closed, attention resting on the breath or on sounds as they come and go, the open-monitoring style the protocol uses. End with a quiet minute.
Where it sits against the guidelines
The federal Physical Activity Guidelines for Americans, second edition, ask adults for 150 to 300 minutes a week of moderate-intensity aerobic activity or 75 to 150 minutes of vigorous activity, plus muscle-strengthening activity on 2 or more days, and tell older adults to add balance training. They count minutes, not styles of practice, and a session of this kind is light to moderate work with a balance component, not a replacement for brisk walking or lifting. The trial's participants practiced for 45 days. To try this session on the same terms: five or six sessions a week for six weeks, at a fixed time, with a weekly note on how you sleep.
