A free breathing exercise website you can use anywhere

ClearBreaths is a free breathing exercise website: open it in any browser and start breathing in seconds — nothing to download. The timer above paces a balanced 5-seconds-in, 5-seconds-out rhythm (coherent breathing) that suits almost everyone. When you want a specific pattern, pick one of the guided exercises below.

Slow, paced breathing gently shifts you into “rest and digest” mode. A longer, relaxed exhale signals safety to your nervous system and can slow a racing heart — which is why just a few minutes can leave you calmer, more focused, and ready for sleep.

Frequently asked questions

How do I do a breathing exercise online?

Press start on the timer above and breathe with the orb — inhale as it grows, exhale as it shrinks. It paces a gentle 5-second-in, 5-second-out rhythm that suits almost everyone. No app, account, or sign-up needed.

Are these breathing exercises really free?

Yes. Every breathing exercise and visual timer on this page is free to use as many times as you like, on any device. If you want a plan matched to your goal — sleep, calm, focus, or energy — the optional 60-second quiz builds one around you.

Which breathing exercise should I start with?

If you are stressed or anxious, try box breathing or the physiological sigh. For sleep, try 4-7-8 breathing. For steady all-day calm, try coherent breathing. The timer above works for a simple, balanced breath if you are not sure.

Do I need to download anything?

No. This is a breathing exercise website that runs entirely in your browser — open it on your phone, tablet, or computer and start breathing. Nothing to install.

How long should a breathing exercise be?

Most people feel calmer within 1–3 minutes. A few rounds is often enough to settle a racing mind. Stop sooner if you ever feel light-headed and breathe normally.

ClearBreaths is a wellbeing tool, not a medical treatment. Stop if you feel light-headed.
