Breathing exercises for anxiety

Which breathing pattern should I choose?

All four patterns slow your breathing down, but they feel different and suit different moments. If you are unsure, start with whichever looks easiest. The best pattern is the one you will actually use.

• Box breathing (4-4-4-4): equal counts of inhale, hold, exhale and hold. Steady and structured, it suits moments when you need to stay focused under pressure, such as before a presentation, a difficult call or an exam.
• 4-7-8 breathing: a short inhale, a long hold and an even longer exhale. Many people use it to wind down at night or settle after an upsetting moment. The hold takes some practice.
• Physiological sigh (cyclic sighing): two inhales through the nose, then one long, slow exhale through the mouth. Quick to learn and handy when a wave of stress hits and you want to settle without counting.
• Coherent breathing: an even, slow rhythm of about 5.5 seconds in and 5.5 seconds out, with no holds. Gentle and easy to sustain, which makes it a good choice for longer sessions and daily practice.

Why slow breathing can help you feel calmer

Breathing is one of the few body functions that runs automatically but can also be controlled on purpose. When you are anxious, breathing often becomes faster and shallower and moves up into the chest. Deliberately slowing it down works in the opposite direction, and many people notice their body following.

Research reviews support the general idea. A 2018 systematic review of slow-breathing studies found that breathing at around six breaths per minute or slower was associated with higher heart rate variability, greater relaxation and lower physiological arousal. Heart rate variability, the natural beat-to-beat variation in your heart rate, tends to be higher when the body is in a calmer, more flexible state.

The evidence for each named technique varies. Cyclic sighing has been tested directly in a randomized study; box breathing was part of the same comparison; 4-7-8 breathing rests mainly on the broader slow-breathing research and long practical tradition. None of them is a treatment for an anxiety disorder, but all are low-cost tools worth trying.

About coherent breathing

Coherent breathing does not have its own page on this site, so here is the short version. At about 5.5 seconds in and 5.5 seconds out, you take roughly 5.5 breaths per minute. That sits in the range used in heart rate variability biofeedback, where people learn to breathe at roughly 5 to 6 breaths per minute, a pace often called resonance breathing because heart rate and breathing tend to rise and fall together most strongly around that rate.

The ideal pace varies a little from person to person. If 5.5 seconds feels strained, a slightly quicker rhythm is fine. Because there are no holds, coherent breathing is often the most comfortable option for people who find breath-holding unpleasant, and it works well for sessions of 10 minutes or more.

Using breathing exercises when you feel anxious

In a moment of acute stress, keep it simple. The physiological sigh is often the easiest place to start because it takes only a few breaths and does not ask you to hold your breath. If you have a bit more time, a few minutes of box or coherent breathing can help you stay steady.

Do not aim to make anxiety disappear. The goal is to give your body a slower rhythm to follow and your mind something concrete to focus on. Some people feel calmer within a minute; for others the effect is subtle and builds with practice. Both are normal.

If focusing on your breath makes you feel more anxious, which does happen for some people, switch to a gentler pattern, shorten the counts, or try a grounding technique instead, such as naming five things you can see around you.

Building a daily breathing practice

Breathing exercises tend to be most useful when you have practiced them while calm. If the first time you try box breathing is in the middle of a panic, the counting itself can feel stressful. A few minutes a day turns the pattern into a familiar habit you can reach for when you need it.

• Pick a fixed time, such as after waking, before lunch or as part of your evening routine.
• Start with 2 to 5 minutes. A short daily session is easier to keep up than an occasional long one.
• Inhale through your nose when you can, and let your belly rather than your shoulders do the moving.
• Sit upright with your feet on the floor, or lie on your back with your knees bent.
• Adjust the counts if you need to. Every pattern can be shortened while you build comfort.
