Search for breathing exercises and you will quickly run into three names: box breathing, 4-7-8 breathing, and some version of "breathe out longer than you breathe in". Each has fans. Each has its own story. And if you are anxious, the last thing you need is to feel like you picked the wrong one.
The good news is that these techniques have more in common than they differ. All three slow your breathing down, and all three give your mind something steady to focus on. The differences are mainly in the details, especially around breath holds.
The three techniques at a glance
| Box breathing | 4-7-8 breathing | Extended exhale | |
|---|---|---|---|
| Pattern | In 4, hold 4, out 4, hold 4 | In 4, hold 7, out 8 | In about 3–4, out about 5–6, no holds |
| Breath holds | Two per cycle | One long hold | None |
| Length of one cycle | About 16 seconds | About 19 seconds | About 8–10 seconds |
| Main focus | Even, steady rhythm | Long hold and long exhale | Slow, gentle out-breath |
| Often used for | Focus under pressure, everyday stress | Winding down, sleep | Acute anxiety, stress, settling down |
| Ease when panicking | Moderate to hard | Often hard | Usually easiest |
The counts are typical starting points. Many people shorten them at first and that is completely fine.
Box breathing
Box breathing, also called square breathing or 4x4 breathing, uses four equal sides: breathe in for 4, hold for 4, breathe out for 4, hold for 4. Cleveland Clinic notes that it is associated with the US Navy SEALs and draws on older breath-control traditions. It recommends staying at your comfort level and breathing very gently, without straining.
Who it may suit
- People who like structure and counting
- Moments where you need to stay alert and focused, like before a presentation or exam
- Practising on calm days as a routine
Things to keep in mind
The two holds are the hardest part for many people. If you already feel short of breath, holding with full lungs and then again with empty lungs can feel uncomfortable. The equal-length exhale also does not emphasise the out-breath in the way the other two techniques do.
In the Stanford study by Balban and colleagues (2023), box breathing was one of three daily five-minute practices tested over a month. All the breathing practices were associated with improved mood, though the exhale-focused practice (cyclic sighing) showed the largest effects on mood and breathing rate.
4-7-8 breathing
The 4-7-8 method was popularised by Dr Andrew Weil and, according to Cleveland Clinic, draws on pranayama breath-control traditions. You breathe in through your nose for 4, hold for 7, and breathe out through your mouth with a whooshing sound for 8. The usual advice is to repeat it for about four cycles.
Who it may suit
- People winding down in the evening or trying to fall asleep
- Those who enjoy a clear, set ritual
- People who already feel fairly calm and want to deepen that
Things to keep in mind
The seven-count hold is long, especially when your body is asking for air. Cleveland Clinic mentions that beginners may feel lightheaded. The counts are also relative rather than literal seconds, so it can be done faster, but the ratio still asks for a hold almost twice as long as the in-breath.
The research specifically on 4-7-8 is limited. One small study of healthy young adults by Vierra and colleagues (2022) found that a short session was followed by lower heart rate and blood pressure and changes in heart rate variability. That is promising but not much to build strong conclusions on.
Extended exhale breathing
This is the simplest of the three. You breathe in gently, then breathe out a little longer, with no holds. A common starting point is in for 3 or 4 and out for 5 or 6, but the exact numbers matter less than the shape: out-breath slightly longer than in-breath.
Who it may suit
- People who feel breathless or panicky and find holds difficult
- Anyone who is new to breathing exercises
- People who want something that works without much counting or effort
Why the exhale matters
Your heart rate tends to rise slightly as you breathe in and fall slightly as you breathe out. Slow breathing in general reliably increases heart rate variability, according to a large meta-analysis by Laborde and colleagues (2022). A small study by Magnon and colleagues (2021) found that one session of slow breathing with a longer exhale increased a vagal activity marker and reduced self-reported anxiety. We explain this in more depth in why a longer exhale may calm you.
Things to keep in mind
Because it is so simple, it can feel almost too easy, and some people like the extra structure of box breathing. It also helps to keep the exhale relaxed rather than squeezing out every last bit of air.
Breath holds and panic
During a panic attack, many people describe a feeling of "air hunger", the sense of not getting enough breath, even when oxygen levels are fine. In that state, being asked to stop breathing for four or seven seconds can feel counterintuitive and even alarming.
That does not make holds harmful. Plenty of people use box breathing or 4-7-8 happily, especially once they have practised them on calm days. But if you are mid-panic, or if holds make you feel trapped, you have permission to leave them out. A gentle in-breath and a longer out-breath still slows your breathing down.
Why Daisy uses a simple inhale and a longer exhale
When we designed Don't Panic Daisy, we thought about the moment it would most likely be opened: someone already anxious, breathing fast, maybe with shaking hands. In that moment, fewer instructions are better.
So the flower guides just two things: breathe in as it sways one way, and breathe out a little longer as it sways back. There are no holds to count and no special techniques to remember. The pace starts a little quicker, close to where an anxious breath already is, and slows gradually. You can adjust the level whenever it feels too fast or too slow. If you would like to know more about how it works, the FAQ covers the details.
This is a deliberate trade-off. Box breathing and 4-7-8 have real strengths, and if one of them works for you, keep using it.
How to choose
A few simple questions can help:
- Do breath holds feel okay for you? If yes, box breathing or 4-7-8 are worth trying. If not, start with an extended exhale.
- What is the moment? Focus under pressure may suit box breathing. Bedtime may suit 4-7-8 or a gentle extended exhale. Rising panic usually suits the simplest option.
- How do you feel afterwards? That is the most useful test. Try each one a few times on calm days and notice which feels easiest.
The best technique is the one you will actually reach for when you need it. For most people that means something simple, familiar and comfortable. If you want a step-by-step version for difficult moments, see how to breathe during a panic attack.
