Heart Palpitations During Meditation: What Kayagatasati Teaches
Sit still long enough and the heart gets loud. Four studies explain why, and an old instruction on the body shows what to do with it.
Most heart palpitations during meditation are a normal heartbeat you can finally hear, swinging with slow breath and amplified by fear of the sensation.
- Slow meditative breathing produced heart rate oscillations larger than those of elite athletes asleep (Peng et al., 1999).
- Clinic patients with harmless palpitations were worse at sensing their heartbeat than patients with real arrhythmias (Ehlers et al., 2000).
- A meta-analysis of 724 people found little evidence that meditators sense their heartbeat more accurately (Khalsa et al., 2020).
Heart palpitations during meditation are usually a normal heartbeat you can hear for once. A quiet room removes the noise that covers it the rest of the day, and slow breathing makes the rate rise and fall with every breath. Fear of the sensation can then push the rate up for real. Palpitations that come with chest pain, fainting or breathlessness, or that also happen outside practice, belong with a doctor.
Why can I hear my heartbeat when I meditate?
A post in the hot list of r/Meditation this week asked about this. The writer is young, runs through the week, and has sat for hours a day for about a year. For the past month their heart has pounded after every session, sometimes badly enough to keep them awake. A five-day break made it stop. Coming back to daily sitting brought it back. Their question was plain: is the practice doing something to my heart?
In most cases the practice is doing something to attention. A resting heart beats around seventy times a minute, which comes to about a hundred thousand beats a day. You feel almost none of them. Traffic, talk, screens and movement fill the channel, and the heartbeat sits below all of it. Then you sit still in a quiet room, close your eyes and stop moving. The signal that was there all day comes through.
It also turns up in odd places. In a 2020 study, Sahib Khalsa and colleagues gave meditators and matched non-meditators small doses of a drug that raises heart rate, then asked them to mark on a body outline where they felt the beat. Compared with the non-meditators, the meditators marked far more of the body: the centre of the chest, the belly, the neck, the back and the head. If you feel your pulse in your throat or behind your eyes during a sit, you are in good company.
Ninety seconds with a loud heart
- Keep your eyes closed and your posture as it is. Say "heartbeat" once, silently.
- Find where you feel it most: chest, throat, belly or head. Stay with that one place.
- Count ten beats without trying to change them.
- Let the next few exhales run a little longer than the inhales, without forcing.
- Widen attention to the sounds in the room, with the heartbeat as one of them.
Heart palpitations after meditation and slow breathing
The second cause is the breath itself. Your heart speeds up a little on every inhale and slows a little on every exhale. The pattern is called respiratory sinus arrhythmia, and in a healthy person it is a sign the system is working. A 2017 review of slow-breathing physiology describes how the swing grows as the breath slows down.
Meditation can make that swing large. In 1999, C.-K. Peng and a team at Beth Israel Deaconess in Boston recorded healthy young adults during Chinese Chi and Kundalini meditation. They found "extremely prominent" heart rate oscillations, larger than those of elite athletes asleep and larger than people breathing to a metronome. In a 2004 follow-up with ten experienced meditators, two slow-breathing practices produced big, slow waves in heart rate. A third, the fast "breath of fire", raised the average heart rate outright. The authors called it a meditation paradox: practices people use to calm down can make the heart more active.
So a heart that seems to surge and settle in waves during a slow-breath sit is doing what the lab recorded. Fast breathing practices like kapālabhāti push the rate up, and long breath holds change it too. If you want the longer version of how breath and heart rhythm link, the essay on heart rate variability covers it.
people pooled in a 2020 meta-analysis that found little evidence meditators detect their own heartbeat more accurately than non-meditators (Khalsa et al.)
When your heartbeat makes you anxious during meditation
The third cause is the one that makes it feel dangerous. In 2000, Anke Ehlers and colleagues at Oxford studied patients sent to a cardiology clinic for palpitations. Forty-seven turned out to have a normal heart rhythm that they happened to notice. Sixty-two had a real arrhythmia. Those two groups behaved in opposite ways.
The patients with normal rhythms did worse on a test of counting their own heartbeat. They had more panic disorder, and many reported palpitations during the test itself. The patients with real arrhythmias rarely reported palpitations during the test, and they counted their heartbeat more accurately than both the normal-rhythm group and healthy controls. How loud the heart felt said little about the heart. It said more about how much the person feared their own body.
Meditation does not fix that on its own. Khalsa's group tested Tibetan Buddhist and Kundalini practitioners in 2008 and found they were no better than non-meditators at detecting their heartbeat. They did rate themselves as better at it, and found the task easier. The 2020 study repeated the test under drug-raised heart rates and added a meta-analysis of 724 people. It found little evidence that meditators sense the heart more accurately. Practice changes how confident you feel about the signal, and where you feel it. It does not turn you into a heart monitor.
That gap matters. Sarah Garfinkel's group has shown that a mismatch between how strongly someone feels body signals and how accurately they read them tracks with anxiety. Their 2016 study measured it in autistic adults, but the loop is familiar to anyone who has panicked on a cushion. You notice the beat. You read it as a threat. Adrenaline raises the rate. The faster beat confirms the threat. If this loop sounds like your sits, the essay on relaxation-induced anxiety goes further into it.
Breathing in heavily they know: ‘I’m breathing in heavily.’ Breathing out heavily they know: ‘I’m breathing out heavily.’Majjhima Nikāya 119, Kāyagatāsati Sutta · tr. Bhikkhu Sujato
Kāyagatāsati: knowing the heartbeat as a heartbeat
The early Buddhist texts have a whole discourse on this kind of attention. The Kāyagatāsati Sutta, the discourse on mindfulness immersed in the body (Majjhima Nikāya 119), is a practice manual more than a sermon. It starts with the breath, and its instruction is flat and exact: breathing in heavily, the practitioner knows they are breathing in heavily. Breathing out lightly, they know they are breathing out lightly. Nothing gets added to the observation.
Later in the same text, the practitioner goes through the parts of the body one by one. The heart is on the list, between the kidneys and the liver. It gets no special status. It is one organ among thirty-one, to be known the way you would know sesame from rice in a sack of grain, which is the image the text itself uses.
Read as a record of practice, that is a clear method for the loop above. A strong beat is known as strong. A fast beat is known as fast. The forecast about what it means stays off the table. Modern panic treatment uses a similar move: therapists have people bring on a racing heart on purpose, by running on the spot or breathing fast, until the sensation stops meaning danger. The essay on the second arrow looks at the same split between a sensation and the story added to it.
The discourse gives a second clue. Its opening lines ask the practitioner to breathe in and out "stilling the physical process", the breath being the bodily process closest to hand. Physiology gives that an address. The exhale is the half of the breath on which the heart slows. Lengthen it a little, without forcing, and each beat on the out-breath arrives a fraction later.
Is it normal for your heart to race while meditating?
For most people, most of the time, yes. The usual causes are the ones above: a normal beat you can hear for once, the heart rising and falling with slow breath, faster breathing styles that raise the rate, and fear feeding the whole thing. Strong emotion surfacing in a sit can do it too, the same way tears can arrive without warning.
Dose matters too. The Reddit writer sits for hours a day and works through painful memories in those hours. The Varieties of Contemplative Experience study at Brown interviewed Western practitioners about the hard side of meditation and catalogued 59 kinds of difficult experience, including a whole somatic domain. It also found that practice-level factors, such as how much and how intensely someone sits, shaped how those experiences went. If the pounding started when your practice grew and stopped when you paused, try cutting the hours back before anything else. That pattern points at the amount of practice.
Some signs mean the cushion is the wrong place to work it out. See a doctor if palpitations also happen in ordinary life, come with chest pain, fainting, near-fainting or shortness of breath, feel irregular and fast for more than a few minutes, or if you have a known heart condition or a family history of sudden cardiac death. Until you have been checked, leave out forceful breathing and long breath holds, and sit with the plain breath instead. Nothing in this essay is a diagnosis.
How to meditate when your heartbeat feels loud
When the beat gets loud, the aim is to let it be loud without adding to it. The practice card on this page takes about ninety seconds. Keep the breath natural at first. Lengthen the exhale only once the heartbeat has become one more thing in the room.
The heart itself may not change much with practice. What can change is how quickly the mind files the beat under "body, working" instead of "danger". That filing comes from repetition, which is why a short daily sit helps more here than a long one once a month.
“Perhaps all the dragons in our lives are princesses who are only waiting to see us act, just once, with beauty and courage.”Rainer Maria Rilke · Letters to a Young Poet 8, tr. Stephen Mitchell
Questions
Why is my heart pounding during meditation?
Usually because you can hear it for once. Stillness removes the noise that normally covers the heartbeat, slow breathing makes the rate rise and fall with each breath, and worry about the sensation can raise the rate further. If it also happens in daily life or comes with chest pain, fainting or breathlessness, see a doctor.
Is it normal to feel your heartbeat when meditating?
Yes. In a 2020 study, experienced meditators reported feeling the heartbeat across the chest, belly, neck, back and head more than non-meditators did. Feeling it widely is common among people who sit. It says more about where attention goes than about the heart.
Can meditation cause heart palpitations?
It can change heart rhythm in harmless ways. Slow-breathing practices produce large waves in heart rate, and fast practices like breath of fire raise the average rate. Very long daily sessions can also bring strong body sensations. If palpitations started when your practice grew, cut the hours back first.
Why does my heart race after breathwork?
Fast breathing styles raise heart rate while you do them, and breath holds shift it too. In a 2004 study, breath of fire raised the average heart rate of experienced meditators, while slower practices did not. Give the body a few minutes of ordinary breathing afterward before you stand up.
When should I worry about palpitations during meditation?
See a doctor if palpitations happen outside practice as well, feel fast and irregular for more than a few minutes, or come with chest pain, fainting, near-fainting or shortness of breath. The same applies if you have a heart condition or a family history of sudden cardiac death.
We report extremely prominent heart rate oscillations associated with slow breathing during specific traditional forms of Chinese Chi and Kundalini Yoga meditation techniques in healthy young adults.
