What happens to your heart rate when you meditate

Glance at your watch two minutes into a sit and you might see 74. Glance again at the bell and it says 66. Somewhere in between, without asking it to, your heart let go of eight beats a minute.

That small slide is the most common thing a heart does during meditation. It isn't the only thing, and the exceptions are where people get confused, so let's take both.

Why heart rate usually drops

Sitting still means your muscles stop asking for blood, and your heart can ease off. Most practices also slow the breath. Each in-breath nudges the heart a little faster and each out-breath lets it slow, and as breathing lengthens, the slowing side starts to win. Over the first few minutes the average comes down.

How far it falls depends on a pile of ordinary things: how active you were before you sat, what you ate, your morning coffee, a warm room, a cold coming on, and the practice itself. A walk up the stairs right before you sit can make the drop look dramatic. A slow morning in bed can make it look like nothing happened.

Why it sometimes goes up

Some practices are built to wake you up. Kapalabhati and bhastrika raise arousal on purpose, and so do certain Vajrayana visualisations. Even among quiet practices there are differences. In one study, people's heart rates ran higher during loving-kindness and thought-observation than during simple breath meditation.

Effort pushes it up too. If you're gripping your attention, or holding your body rigid so you won't move, your heart notices. So does feeling. Sit quietly for long enough and old memories surface, and the body answers them. And the first minute is often noisy anyway: you rushed to the cushion, you checked your watch, you're still arriving.

If your heart regularly races or pounds while you meditate and it worries you, or it comes with dizziness or chest discomfort, stop and see a doctor. A meditation app can't tell you what's going on there.

Is there a good meditation heart rate?

No. Adult resting heart rates cover a wide range, and fit people often sit in the 50s. Asking whether 62 is good gets you nowhere. Ask how today compares with your usual sits of the same kind.

A bigger drop than usual might mean you arrived calmer, breathed slower, or were nodding off. A smaller one might mean a stressful morning or a second coffee. Your own baseline is the only comparison that's fair to you.

And HRV?

Heart-rate variability is the beat-to-beat wobble in the timing of your heartbeats. It's a real signal, and during meditation it's very easy to misread.

Breathe slowly, near six breaths a minute, and the rise and fall of your heart with each breath gets much bigger. HRV jumps. That jump comes from your breathing, and it would happen if you were breathing slowly while doing your taxes. Over the longer run, a 2021 meta-analysis of 19 randomised trials found no significant rise in vagal HRV from mindfulness training compared with control groups.

Your watch adds its own limits. Apple Watch logs occasional HRV samples (SDNN) in Apple Health that aren't tied to your sit, and it doesn't give apps live beat-to-beat data during a session. If you want proper HRV, a chest strap such as a Polar H10 is the tool.

Breathing may be the more telling long-term signal anyway. Long-term meditators in one study breathed about 1.6 breaths a minute slower at rest than non-meditators, and the gap grew with the hours they had spent on retreat. I cover the rest in Does meditation increase HRV?

A fair way to watch your own heart rate

Keep the conditions boring. Sit for the same length at roughly the same time of day, and compare silent sits with silent sits, japa with japa. Then look at the shape instead of one number: where it started, how quickly it settled, where it ended up.

Last, write one line about how the sit felt before you look. A number beside your own words tells you far more than a number alone, and it keeps the number from telling you how you felt.

That's how Dhyaan shows heart rate. You say how the sit felt first. Then you see the settle from start to finish, set against your own past sits, with no score attached.
