How to breathe with a longer exhale

Longer exhale breathing, also called extended exhale or 4-6 breathing, asks for one thing: breathe out a little longer than you breathe in. In for 4 seconds, out for 6, with no holds.

5 short steps, a chart of one round and the mistakes to avoid. One round takes 10 seconds, which is 6 breaths a minute; five minutes is 30 rounds.

In the Haptic Calm appThe vibration grows while you breathe in and slowly fades over the longer exhale, so you can keep your eyes closed. Longer exhale is a Pro method. Its 4-in, 6-out rhythm is also the last minute of Calm now, which is free for everyone. Haptic Calm 2.0, which adds the breathing methods, is coming soon as a free update.

The rhythm

What one round looks like

  1. In 4 s
  2. Out 6 s
The line is the vibration in Haptic Calm: it rises while you breathe in and fades while you breathe out. After the dashed line, shown fainter, the next round begins.

Step by step

The 5 steps

  1. Step 1

    Get set

    • Sit or lie down and let your shoulders drop.
    • Rest a hand on your belly if it helps you feel the breath, then breathe out gently once.

    TipIf 6 seconds feels long at first, start with in 4, out 5.

  2. Step 2

    Breathe in for 4

    • Breathe in slowly through your nose while you count 1, 2, 3, 4.
    • Let your belly rise first, then your chest.

    TipA comfortable breath is enough. A smaller breath is easier to let out slowly.

  3. Step 3

    Breathe out for 6

    • Breathe out through your nose, or through softly pursed lips, while you count 1 to 6.
    • Let the air go at an even pace, like a slow, quiet sigh.

    TipIf you run out of air before 6, breathe in a little less next time rather than squeezing.

  4. Step 4

    Go straight into the next breath

    • When the exhale ends, let the next breath in begin. There is no hold in this method.
    • Keep repeating for 3 to 10 minutes.

    TipFive minutes is 30 rounds. No need to count them: a timer or the vibration keeps track.

  5. Step 5

    Come back slowly

    • When you finish, let your breathing return to its own pace for a few breaths.
    • Notice how your body feels before you get up.

Make it easier or harder

Easier
Try in 4, out 5. Or start with steady breathing, 4 in and 4 out, and lengthen the exhale later.
Harder
Lengthen only the exhale, one second at a time: in 4, out 7, then out 8. The 4-7-8 method goes further and adds a 7-second hold.
Too strained
If you feel short of air or light-headed, shorten the exhale or breathe more gently. Slow should still feel easy.

Common mistakes

  • Forcing the exhale. Pushing the last bit of air out makes you tense, the opposite of the goal.
  • Holding your breath without meaning to, at the top or bottom of the breath. Let the in-breath and out-breath flow into each other.
  • Taking a huge breath in so there’s enough air for a long exhale. A normal-sized breath is easier to let out slowly.
  • Breathing out fast, then waiting. The 6 seconds should be one slow, even exhale, not a quick puff followed by a pause.

Before you start

  • Breathe gently. Stop and return to normal breathing if you feel dizzy, light-headed, tingly or tight in the chest.
  • If you are pregnant, or have a heart, lung or blood-pressure condition, ask your doctor before practicing breath holds or long exhales.
  • Don’t practice while driving, in water or anywhere a moment of light-headedness could be unsafe.
  • Breathing exercises can help you relax. They do not diagnose or treat any condition, and they don’t replace professional care.

Questions

What is longer exhale breathing?

Longer exhale breathing, also called extended exhale breathing, is any pattern where you breathe out for longer than you breathe in. A simple version is 4-6 breathing: in for 4 seconds, out for 6. One round takes 10 seconds, so you breathe 6 times a minute.

Why does a longer exhale help you relax?

One common explanation is the link between breathing and heart rate: your heart naturally speeds up a little as you breathe in and slows a little as you breathe out. A longer exhale gives more time to that slower phase. A systematic review of slow breathing, at under about 10 breaths a minute, linked it with higher heart rate variability and with feeling more relaxed and less anxious, though the authors say more research is needed.

Is there research on long exhale breathing?

Mostly on slow breathing in general. In a one-month Stanford study of 108 people, cyclic sighing, an exercise built around a long exhale, practiced about five minutes a day, improved positive mood and lowered breathing rate more than mindfulness meditation. That study did not test 4-6 breathing itself.

How long should I practice?

Three to ten minutes is a good session, for example to wind down in the evening. Five minutes at 4-6 is 30 rounds. If it starts to feel like effort, stop sooner: a short, easy session is better than a long, strained one.

Can I do it with my eyes closed in Haptic Calm?

Yes. Haptic Calm guides it by touch: the vibration rises as you breathe in and fades slowly over the 6-second exhale. Longer exhale is a Pro method, but the free Calm now session ends with a minute of the same rhythm, in 4 and out 6, after three physiological sighs.
