Frequently asked questions
What is box breathing?
Box breathing is a 4-part pattern: inhale, hold, exhale, hold — usually 4 seconds each. Follow the marker around the square to keep an even rhythm.
How many rounds of box breathing should I do?
Four to six rounds (about 1–2 minutes) is a common start. Stop if you feel lightheaded and return to normal breathing.
What's the difference between box breathing and 4-7-8 breathing?
Box breathing uses equal sides (4-4-4-4). 4-7-8 uses inhale 4, hold 7, and exhale 8. Use the 4-7-8 preset to switch.
Can box breathing help with anxiety?
A slow, even pattern can help many people feel calmer. This timer is a practice aid, not medical advice.
