What Kundalini yoga is
Kundalini yoga is a style that combines movement, breathing, meditation and chanting. A 2026 systematic review describes the practices in its studies as pranayama (breath practices), asana/kriya (movement sets), meditation and chanting. [1] It is one of several styles described on the yoga styles overview.The word kundalini comes from older Indian traditions. An encyclopedia summary describes kundalini in those traditions as an energy, often pictured as a serpent coiled at the base of the spine. [2] That is a traditional framework, not a measured part of anatomy. See chakras, nadis and the subtle body for how these ideas are used and what research does and does not say about them.
Where it comes from
The same encyclopedia page notes that many of the oldest sources on kundalini come through manuals of the tantric and hatha traditions. [2] The style most people meet in Western classes is a later form, "Kundalini Yoga as taught by Yogi Bhajan." He was born in the Punjab region in 1929 and moved to the United States in late 1968, according to Yoga Journal. [3]Historian Philip Deslippe, writing in 2012, concluded that in the early years of the organization Yogi Bhajan used the physical yoga of another teacher, Swami Dhirendra Brahmachari. [4] Deslippe's article is one scholarly account of where the style came from, and other accounts exist. See the history of yoga and cultural respect in yoga for wider context.
Controversy about the founder
In 2020 the organization that oversees Yogi Bhajan's estate commissioned an outside investigation by a group called An Olive Branch. Its report said that "much of the alleged conduct, more likely than not occurred." [3] The investigators interviewed or received statements from 299 people, and the scope covered sexual and spiritual abuse. [3] Of those, 140 refuted any allegations of wrongdoing, according to the same account. [3] We have not read the full report itself, only this magazine's account of it.This page does not tell you what to decide; it is information so you can.
What a class can involve
Classes vary a lot by teacher. Based on the review we read, programs combined breath practices, movement sets, meditation and chanting, and ran from 6 weeks to 12 months, most for 8 to 12 weeks. [1] In the anxiety trial below, classes were 120 minutes long, held for groups of four to six with two instructors, plus 20 minutes of daily homework. [5]The review lists chanting among the practices; for background see mantra, Om and chanting in yoga. You can choose to listen or sit out any part that does not feel right.
What research shows
| Question | What the source found | Label |
|---|---|---|
| Generalized anxiety disorder | In a trial of 226 adults, 54.2% of the Kundalini group responded versus 33.0% of stress education, but CBT reached 70.8% and Kundalini was not shown to be as effective as CBT [5] | promising but limited |
| Mild cognitive impairment | 81 older adults: memory improved in both Kundalini and memory training, but only Kundalini improved executive function [6] | promising but limited |
| Insomnia (sleep onset) | 20 people per group; self-reported sleep improved more than with a sleep hygiene program [7] | promising but limited |
| Broad claims across conditions | A review of 15 trials, approximately 1,370 people, found improvements in several areas; its authors call for larger, standardized trials [1] | promising but limited |
The anxiety trial is the largest. Only 68.6% of participants completed the final assessment, and the comparison group received stress education rather than a different movement practice. [5] NCCIH summarizes it this way: Kundalini yoga improved symptoms but was less helpful than cognitive behavioral therapy, an established first-line treatment. [8] The sleep study's authors say objective measures such as actigraphy and sleep studies are still needed. [7]
Yoga cannot be blinded, and most of these outcomes were self-reported. Treat the 2026 review's wide-ranging conclusions with care: we read only its abstract, and it says larger standardized trials with active comparators and longer follow-up are needed. [1] For wider context see yoga for anxiety, yoga for sleep and yoga for cognitive health.
Choosing a teacher
Yoga teaching is generally not regulated, so ask about training, modifications, and whether chanting and breath practices are optional. We do not list or rate teachers or studios. See how to choose a yoga style.Frequently asked questions
Is Kundalini yoga the same as the kundalini in older Indian texts?
The concept of kundalini appears in tantric and hatha manuals. [2] The style taught in Western classes was shaped in the 20th century, and scholars describe a mix of sources. [4] Kundalini as an energy is a traditional idea, not an established biological finding.
Does Kundalini yoga treat anxiety?
In one trial of generalized anxiety disorder, more people responded to Kundalini yoga than to stress education, but fewer than to CBT, which remains first-line. [5][8] Evidence is promising but limited.
Is Kundalini yoga safe?
A 2026 review reported no serious adverse events in its trials. [1] Forceful breathing and inversions have been involved in case reports across yoga styles, so go gently and tell your teacher about health conditions. [9]
Should I avoid it because of the allegations about Yogi Bhajan?
That is a personal choice. An investigation commissioned by the organization found much of the alleged conduct more likely than not occurred. [3] Trials test the practices, not the founder, and the abstracts we read do not name the lineage each trial followed.
Can it help memory or sleep?
Small trials found improvements in executive function and self-reported sleep. [6][7] They were small and need confirmation.

Safety and cautions
NCCIH advises people new to yoga to avoid extreme practices such as headstands, shoulder stands, the lotus position and forceful breathing. [8] If a class includes fast or forceful breathing, ask the teacher about it beforehand, keep it gentle, and stop if you feel dizzy, tingly or panicky. Breath practices like these are not for use in or near water. Our pranayama page covers breath practices in more detail.
People with glaucoma or weak bones should avoid inversions and forceful practices, according to one review. [10] A 2026 review of case reports also counted 6 psychiatric events among 84, and 54% of people in these reports had pre-existing vulnerabilities. [9]
Who should check first
If you are in crisis or thinking about harming yourself, call 988 in the US. For an emergency, call 911. Yoga is not a replacement for treatment that you and your clinician have chosen.
