Key takeaways
Box breathing (a 4-4-4-4 count) is generally better for staying calm and focused before or during a stressful situation, while 4-7-8 breathing (a 4-7-8 count with a long exhale) is generally better for winding down before sleep or de-escalating strong anxiety โ both work by slowing your breathing rate and extending the exhale, which activates the parasympathetic nervous system.
Box breathing follows a simple even pattern: inhale for 4 counts, hold for 4, exhale for 4, hold for 4, then repeat. The 'box' refers to the four equal sides. Because every phase is the same length, it's easy to keep track of mentally, which is part of why it's popular with people who need to stay sharp under pressure, rather than fully switch off.
4-7-8 breathing uses an uneven, exhale-dominant pattern: inhale through the nose for 4 counts, hold for 7, exhale slowly through the mouth for 8. Popularized by Dr. Andrew Weil, its defining feature is that the exhale phase is twice as long as the inhale, with a long hold in between. That extended exhale is doing most of the calming work.
Exhaling activates the parasympathetic, or 'rest-and-digest,' branch of the nervous system via the vagus nerve, while inhaling slightly activates the sympathetic branch. A pattern with a longer exhale than inhale, like 4-7-8, tilts the balance more strongly toward calming. Box breathing's equal counts are more balanced, which is why it tends to produce steady, alert calm rather than the drowsy, heavy calm 4-7-8 can produce. If you want the full mechanism behind why slow breathing lowers stress at all, see how to lower your stress level fast.
For a sudden anxiety spike, 4-7-8 tends to work faster precisely because of that long exhale โ but the long breath-holds can feel uncomfortable or even panic-inducing for some people at first. Box breathing's even, predictable rhythm is often easier to sustain if holding your breath for 7-8 counts feels like too much, especially for beginners.
Box breathing is the better choice here. Because it doesn't over-relax you, it lowers physiological arousal without making you feel foggy or sleepy, which is useful right before something that requires alertness and focus, not just calm.
4-7-8 breathing is the more common choice for winding down, since the goal at bedtime is to feel drowsy, and the longer exhale and hold naturally slow things down more than box breathing's even rhythm does.
Not definitively. Both rely on the same core mechanism of slowed breathing rate, extended exhale, and vagal stimulation, and both have real evidence behind reducing physiological arousal. The better technique is the one that matches your situation: box breathing for staying calm and alert, 4-7-8 for winding down or de-escalating a strong spike. You can also gauge which technique works better for your body by watching HRV trends afterward โ see what HRV actually tells you about stress. Many people end up using both, just for different moments.
Exhale's guided haptic breathing sessions, where the phone vibrates in rhythm with your breath, can walk you through structured patterns like these during its one-tap 60-second SOS reset, so you don't have to count breaths yourself while you're already stressed.

It can help you relax, but 4-7-8's longer exhale and breath-holds are generally more effective for triggering drowsiness before sleep.
Mild lightheadedness can happen early on due to the long breath-holds. If this happens, reduce the number of rounds or shorten the hold.
Most people notice a shift within 4-8 breath cycles, roughly 1-2 minutes, for either technique.
Yes. Many people use box breathing for daytime focus and 4-7-8 for winding down at night.
