Breathing Exercise Online Free — 8 Guided Techniques
Guided box breathing, 4-7-8 technique, and Wim Hof method with visual timer and animation. Free stress relief, anxiety management, and sleep improvement tool — no app download needed.
How to Use
Choose a breathing technique from the pattern cards — each shows timing and benefits.
Set the number of rounds (1-50). Each round completes one full cycle of the pattern.
Optionally select a transition sound and ambient background.
Press Start and follow the animated circle — inhale when it grows, exhale when it shrinks.
After the session, review your statistics and start again if desired.
Master breathing techniques for stress relief, focus, and energy
Controlled breathing activates the parasympathetic nervous system — the "rest and digest" response. Different patterns target different outcomes: slowing the breath reduces cortisol and blood pressure, while fast breathing increases alertness.
Box Breathing (4-4-4-4)
Used by Navy SEALs and first responders for stress management. The equal timing of all four phases creates a calming rhythm that reduces anxiety and improves focus. Studies show it can lower cortisol within 5 minutes.
4-7-8 Breathing
Developed by Dr. Andrew Weil based on pranayama. The extended exhale activates the vagus nerve, triggering deep relaxation. Often called a "natural tranquilizer for the nervous system."
Coherent Breathing
Breathing at ~6 breaths per minute maximizes heart rate variability (HRV) — a key marker of nervous system health. Research by Dr. Stephen Porges links high HRV to better stress resilience and emotional regulation.
Triangle Breathing
A simpler variation of box breathing without the second hold. The three equal phases are easy to follow and effective for beginners. Used in yoga as a foundational breath control exercise.
Physiological Sigh
Research from Stanford (Dr. Andrew Huberman) shows the double inhale reinflates collapsed alveoli in the lungs, maximizing CO2 offload on the long exhale. This is the fastest known voluntary technique to reduce stress.
Energizing Breath
Rapid breathing activates the sympathetic nervous system, increasing heart rate and alertness. Similar to Kapalabhati pranayama. Best used as a brief energy boost, not for extended periods.
Wim Hof Method
Combines controlled hyperventilation with breath retention. The 30 rapid breaths increase blood oxygen and alkalinity, while the hold triggers a powerful dive reflex. Peer-reviewed research shows it can modulate the immune response.
