7 Min 4-7-8 Timer
Dr. Weil's classic sleep breathing technique extended
The 4-7-8 breathing pattern (developed by Dr. Andrew Weil) uses the ratio of 4-second inhale, 7-second hold, 8-second exhale to create profound parasympathetic activation. Seven minutes of this pattern produces approximately 28 complete cycles, creating deep relaxation comparable to sleep-inducing medication but without any side effects.
The 7-minute 4-7-8 session is ideal for sleep preparation, deep stress recovery, or anytime you need powerful relaxation. The longer hold and extended exhale create the strongest possible parasympathetic signal, making this one of the most effective breathing techniques for nervous system downregulation.
The 4-7-8 pattern is particularly effective because the 7-second hold increases CO2 slightly, then the 8-second exhale provides an extended parasympathetic stimulus. Together, these create a uniquely powerful relaxation effect that many people find even more effective than longer sessions of other techniques.

Frequently Asked Questions
Why is the 4-7-8 ratio so effective for sleep?
The ratio combines the benefits of breath-hold training (4-second inhale builds capacity) with an extended exhale (8 seconds activates parasympathetic). This combination creates a uniquely powerful relaxation effect.
How long before sleep should I do 4-7-8 breathing?
Do it right before bed — immediately in bed is ideal. The deep relaxation state typically leads to sleep within minutes. Some people find they fall asleep during the session itself.
Can I do 4-7-8 breathing longer than 7 minutes?
Yes, many people do 10-15 minute sessions. But 7 minutes is usually sufficient for sleep preparation. Longer sessions deepen the effect but with diminishing returns.
