What is tummo breathing?
Tummo breathing is a 1,000-year-old Tibetan meditation technique that uses rhythmic breathing and inner fire visualization to generate body heat. Practitioners inhale deeply into the belly and exhale sharply while visualizing a flame at the navel center. Harvard research confirmed monks can raise body temperature by up to 8°C using this technique.
Technique overview
What it is
G-tummo is a Tibetan tantric meditation practice with over 1,000 years of history. Practitioners sit in cold temperatures and use breath combined with visualization to generate measurable body heat. The technique centers on deep, belly-filling inhales paired with shorter exhales, combined with visualization of an inner fire rising from the navel center. It is part of the Six Yogas of Naropa, a set of advanced Buddhist meditation practices transmitted through the Kagyu lineage.
How it works
The asymmetric breathing pattern (roughly 2 seconds inhale, 1 second exhale) with no holds creates continuous rhythmic breathing that increases metabolic heat production. The forceful diaphragmatic action combined with focused attention on the navel center stimulates thermogenesis. The deep belly inhales maximize oxygen intake while the sharp exhales maintain the energetic pumping rhythm. More advanced practitioners add breath retention (vase breathing or kumbhaka), where the breath is held at the belly to intensify the heat-generating effect.
Tummo vs Wim Hof: Understanding the Difference
Wim Hof has acknowledged drawing from the tummo tradition. Both techniques use hyperventilation-style breathing to create physiological changes. Key differences: tummo includes visualization of inner fire and is traditionally part of a spiritual practice within Tibetan Buddhism; Wim Hof adds a structured protocol with timed breath retention holds and deliberate cold exposure. The tummo breathing pattern is slower and more intentional than Wim Hof power breathing, which uses 30–40 rapid breaths per round. Tummo is a contemplative practice; Wim Hof is a performance protocol.
When to use
Advanced meditation practice, before cold exposure, energy cultivation, and spiritual practice. Tummo is not a beginner technique—it requires comfort with breathwork fundamentals and the ability to maintain focused visualization for extended periods. It pairs well with a seated meditation routine and can serve as the core practice for those exploring Tibetan Buddhist methods.
When to skip
Beginners without breathwork experience should start with simpler techniques first. Avoid tummo if you have cardiovascular conditions, are pregnant, are currently ill, or have a history of seizures. The hyperventilation component can cause dizziness and lightheadedness. Always practice seated with support nearby, never in water or while driving.

Sit in meditation posture
Sit cross-legged or in a chair with your spine straight. Relax your shoulders and close your eyes. Place your hands on your knees or in your lap.
30 seconds
- 2
Establish the visualization
Picture a small, bright flame at your navel center, about 2 inches below your belly button. See it clearly — a tiny, intense fire the width of a hair.
1 minute
- 3
Begin rhythmic breathing
Inhale deeply through your nose for 2 seconds, filling your belly completely. Feel the breath stoking the inner flame. Exhale sharply through your nose for 1 second.
2–3 seconds per cycle
- 4
Grow the flame
With each breath, visualize the flame growing brighter and taller. Feel warmth spreading from your navel through your torso, arms, and legs.
5–10 minutes

Rest and absorb
After your breathing rounds, sit quietly for 2–3 minutes. Maintain awareness of the warmth. Let your breathing return to normal gradually.

Advanced meditation
Deepen your meditation practice with this powerful Tibetan technique that demands total concentration.
10–20 minutes, once daily
Cold exposure preparation
Use tummo breathing to generate inner heat before cold showers, ice baths, or winter outdoor activities.
5–10 minutes before cold exposure
Energy cultivation
When you need sustained focus and mental energy, tummo activates your inner fire for alertness without caffeine.
5–10 minutes as needed
Suggested frequency
1 session daily, 10–20 minutes. Start with 3–5 minutes and build gradually.
Practice notes
Keep it gentle
Helpful reminders so the pattern stays sustainable day after day.
Visualize the inner flame
Picture a small, bright flame at your navel center. With each inhale, see it grow brighter and warmer. This visualization is central to authentic tummo practice.
Sit upright with a straight spine
Traditional tummo is practiced in lotus or half-lotus position. The straight spine allows for maximum diaphragmatic expansion and energy flow.
Start with shorter sessions
Begin with 3–5 minutes and gradually increase to 15–20 minutes over weeks. The intensity of the practice can cause dizziness in beginners.
Combine with cold exposure carefully
Only add cold exposure after you can maintain inner heat visualization for 10+ minutes. Start with cool (not cold) temperatures.
FAQ
Common questions
Evidence-backed answers we hear from practitioners most often.
What is tummo breathing?
Tummo breathing is an ancient Tibetan meditation technique that uses rhythmic breathing and inner fire visualization to generate body heat. It is part of the Six Yogas of Naropa, a set of advanced practices in Vajrayana Buddhism.
Is tummo the same as Wim Hof breathing?
No. Wim Hof drew inspiration from tummo but created a different protocol. Tummo includes visualization, spiritual context, and a different breathing pattern. Wim Hof adds structured retention holds and a cold exposure protocol.
Is tummo breathing dangerous?
It can be if practiced incorrectly. Risks include hyperventilation, dizziness, and fainting. Always practice seated, never in water or while driving. Start slowly and consider learning from an experienced teacher.
How long does it take to learn tummo?
Basic tummo breathing can be learned in a few sessions, but generating measurable heat typically requires weeks to months of consistent practice. Traditional training takes years under a qualified teacher.
Can tummo really raise body temperature?
Yes. Harvard studies by Herbert Benson (1982) confirmed Tibetan monks could raise finger and toe temperatures by up to 8°C during tummo meditation. Kozhevnikov et al. (2013) showed core body temperature increases in practiced monks.
Do I need a teacher for tummo?
For basic tummo breathing, the guided timer here is a good starting point. For advanced practices involving vase breathing and energy channel work, seeking a qualified teacher in the Tibetan Buddhist tradition is recommended.

Study highlights
Body temperature changes during the practice of g-tummo meditation
Herbert Benson’s Harvard team documented Tibetan monks raising peripheral body temperature by up to 8.3°C during tummo meditation, providing the first Western scientific evidence of voluntary thermoregulation.
Neurocognitive and somatic components of temperature increases during g-tummo meditation
Kozhevnikov et al. found that g-tummo practitioners using ‘forceful breath’ plus visualization could raise core body temperature above normal range, distinguishing somatic and neurocognitive components of the practice.

Safety notes
- Practice seated only — never while standing, driving, swimming, or in water
- Stop immediately if you feel dizzy, lightheaded, or experience tingling in your extremities
- Not recommended for beginners without prior breathwork experience
- Avoid if you have cardiovascular conditions, epilepsy, or are pregnant
- Start with 3–5 minutes and gradually increase duration over weeks
- Consider learning from a qualified teacher for advanced practices
"The ability to raise body temperature through meditation alone represents one of the most striking examples of mind-body interaction documented by science."

"Tummo practitioners demonstrated significant increases in core body temperature, confirming that this ancient technique produces measurable physiological changes."
