Guided breathing exercise
Slow, paced breathing is one of the fastest ways to settle an overactive nervous system. Pick a technique, press start, and follow the circle: expand as you breathe in, hold, and shrink as you breathe out.

Why it helps
What slow breathing does
When you slow your breathing and lengthen the exhale, you nudge the body's parasympathetic, or rest-and-digest, system. Heart rate eases and the sense of urgency that rides along with anxiety tends to come down. It's a skill rather than a cure: it works best practiced regularly, and it sits alongside other support, not instead of it.
Box breathing uses equal counts in, hold, out, and hold, which makes it easy to learn and steady to follow. The 4-7-8 pattern stretches the exhale, which many people find especially calming when winding down at night. If holding for seven or exhaling for eight feels like a lot at first, start with box breathing and build up.
Make it a habit
When to use it
A few slow cycles can help in an anxious moment, before a stressful conversation, or as part of a wind-down before sleep. Practiced a couple of minutes a day, paced breathing also gets easier to reach for when you actually need it. If breathing exercises consistently aren't touching the anxiety, that's useful information worth bringing to a clinician.
Frequently asked questions
Good questions, clear answers
Is this a treatment for anxiety or panic?
No. This is a self-help relaxation tool, not a medical treatment, therapy, or a substitute for care from a clinician. If anxiety or panic is interfering with your life, talk to a professional.
Which technique should I pick?
Box breathing is the easiest place to start and works any time. 4-7-8 emphasizes a long exhale and many people find it calming before sleep. Try each and keep what feels best.
I feel a little lightheaded. Is that normal?
A little is common when you first change your breathing. Slow down or pause. Don't do breath holds while driving or in water, and stop if you feel faint.
Does this save my data?
No. The tool runs entirely in your browser and stores nothing.
