Box Breathing vs 4-7-8 vs Long-Exhale Breathing: Which Is Best for Anxiety?

For most people with anxiety, long-exhale breathing is the best place to start. Breathe in for 4 seconds and out for 6, with no holds. Box breathing is a good second choice, especially for focus. The 4-7-8 method can help some people relax, but it has the least evidence for anxiety, and its long hold is hard for many anxious people.

Below you will find each technique step by step, a side-by-side table, what the studies actually show, and how to choose the right one for you.

Which breathing technique is best for anxiety?

Long-exhale breathing has the strongest support of the three. In a 2025 lab study, 84 college students tried box breathing, 4-7-8 breathing and a slow pace of 6 breaths per minute, including a 4-in, 6-out version. The slow pace raised heart rate variability more than box or 4-7-8 breathing, by a small to medium amount (Marchant et al., 2025). Heart rate variability, often shortened to HRV, is the natural beat-to-beat change in your heart rate. Higher HRV at rest generally goes with a calmer, more flexible nervous system.

The exhale seems to matter on its own. In an earlier study, 30 people breathed at different speeds and ratios. They felt more relaxed and less stressed when the exhale was longer than the inhale, whatever the speed (Van Diest et al., 2014).

That does not make box breathing a bad choice. It lowered anxiety in a real-life study too (Riedl et al., 2026). But if you only learn one pattern, learn the long exhale.

Can technology help you choose and practice the right technique?

Yes, it can. Counting seconds in your head takes attention you may not have when you are anxious, and it is easy to lose the pace. A breathing tool keeps the timing for you, so all you do is follow along.

There are many breathing tools out there, and they are not all alike. Many give you a fixed pattern, so you have to fit the tool. That is a problem here, because the right technique depends on your desired outcome and your ability. Calm in the moment, focus under pressure and winding down at night call for different timings, and a person with panic disorder needs no holds at all.

One tool that can be beneficial is Breath Interval, because it is built around custom breathing exercises. You set the inhale, hold and exhale lengths yourself, so you can shape an exercise around your goal and what you can comfortably do, with shorter counts, no holds or a gentler ratio. It keeps the pace with chimes, so you can relax instead of counting.

You can build all three patterns in it. A tool never replaces judgment, though. If any pattern makes you dizzy or more anxious, stop, whatever the screen says.

How the three techniques compare

All three slow your breathing down. The differences are the holds and the ratio between inhale and exhale. Long-exhale breathing puts all the time into the exhale. Box breathing splits it evenly. The 4-7-8 method has the longest exhale but also a long hold in the middle.

How to do long-exhale breathing

This is the pattern I teach first, because almost anyone can do it anywhere.

1. Sit or stand comfortably. Let your shoulders drop. Put a hand on your belly if it helps you feel the breath.
2. Breathe in gently through your nose for 4 seconds. An easy, ordinary-sized breath, not a big gulp.
3. Breathe out slowly for 6 seconds. Through soft lips or your nose, as if you were letting air out of a balloon.
4. Repeat for 3 to 5 minutes. That is 6 breaths a minute.

If 6 seconds feels like too much, try 3 in and 5 out. Keep the breaths soft. In the 2025 study, the slow pace caused mild over-breathing in some students (Marchant et al., 2025), which can make you feel light-headed. Smaller, quieter breaths avoid that.

How to do box breathing

1. Breathe in through your nose for 4 seconds.
2. Hold gently for 4 seconds. Keep your throat and shoulders relaxed.
3. Breathe out for 4 seconds.
4. Hold with empty lungs for 4 seconds.
5. Repeat for 1 to 5 minutes. Shorten every count to 3 if 4 feels tight.

How to do 4-7-8 breathing

1. Breathe in quietly through your nose for 4 counts.
2. Hold for 7 counts.
3. Breathe out through your mouth for 8 counts.
4. Repeat for 4 to 6 cycles. Stop at any point if the hold makes you uneasy.

Counts can be faster than seconds, especially at first. The 4-7-8 ratio matters more than the exact timing.

What the research shows

The research is real but small. No study has yet compared all three patterns directly on anxiety in people who live with it.

• Slow pace beat box and 4-7-8 on HRV: 84 students, single lab session. The 6-breaths-per-minute patterns raised HRV more than the other two. None of the patterns changed mood or blood pressure in that short session (Marchant et al., 2025).
• A longer exhale felt more relaxing: 30 adults. A long exhale relative to the inhale brought more relaxation and less stress than the reverse (Van Diest et al., 2014).
• Box breathing eased real anxiety: 47 students used one minute of box breathing or cyclic sighing during real anxious moments. Both lowered anxiety more than doing nothing (Riedl et al., 2026).
• Box breathing over a month: in a 108-person trial, five minutes a day of box breathing, cyclic sighing or meditation all lowered anxiety, with no clear winner on anxiety (Balban et al., 2023).
• 4-7-8 in the lab: 43 young adults did three short sets of 4-7-8 breathing. Heart rate and systolic blood pressure dropped slightly afterward. The study did not measure anxiety and had no comparison group that skipped the breathing (Vierra et al., 2022).
• Breathwork in general: a review of 12 randomized trials with 785 adults found breathwork lowered stress and anxiety by a small to moderate amount (Fincham et al., 2023).

The takeaway: slow breathing with a long exhale has the most consistent support, and box breathing is a reasonable alternative. The case for 4-7-8 as an anxiety tool rests more on popularity than on studies.

How to choose the right one for you

• You feel anxious right now: use long-exhale breathing. For an even quicker option, see what breathing exercise works fastest for anxiety.
• You need to stay sharp, before a talk or a game: try box breathing.
• You are winding down at night and not very anxious: 4-7-8 is fine if you like it.
• Holds make you uneasy: skip box and 4-7-8, and stay with the long exhale.

The best technique is the one you will actually practice. A few minutes on calm days makes the pattern easier to reach for when you need it.

Common mistakes

• Taking huge breaths. Bigger is not calmer. Big breaths can lead to light-headedness and tingling.
• Forcing the holds. If a hold feels like air hunger, shorten it or drop it.
• Counting too fast. Rushed counts turn a calming pattern into fast breathing. Slow the count down.
• Switching techniques every time. Pick one pattern and give it a couple of weeks.
• Expecting anxiety to vanish. Breathing turns the volume down. It rarely switches anxiety off.

Who should be careful

• People with panic disorder: breath holds, including box and 4-7-8 breathing, can trigger or worsen symptoms for some. Start with gentle long-exhale breathing.
• People with asthma or another lung condition: avoid forceful breathing and long holds, and check with your doctor first.
• Anyone who feels dizzy, tingling or short of breath: stop, breathe normally, and try again later with shorter counts and smaller breaths.
• People who are pregnant or have a heart condition: talk to your doctor before practicing breath holds.
• Anyone with frequent or severe anxiety: breathing can help, but please also talk to a doctor or therapist.
