Heart coherence: practice the 365 method for free

What is heart coherence?

Heart coherence is a paced breathing technique that helps regulate the autonomic nervous system. By breathing at a rate of 6 breaths per minute (inhale 5 seconds, exhale 5 seconds), the heart enters a state of "coherence" where heart rate variability (HRV) becomes regular and optimal.

The 365 method

The 365 method, popularized by Dr. David O'Hare, is a simple and effective protocol:

• 3 times a day (morning, noon, evening)
• 6 breaths per minute
• 5 minutes per session

The immediate effects (lower cortisol, vagus nerve activation) last about 4 to 6 hours, which is why it's worth practicing several times a day.

The scientifically proven benefits

Numerous studies show that practicing heart coherence regularly helps to:

• Reduce cortisol (the stress hormone) by 20 to 30%
• Activate the parasympathetic system via the vagus nerve
• Improve heart rate variability (a marker of good health)
• Reduce anxiety and rumination
• Improve focus and decision-making
• Support better sleep onset

Which rhythm should you choose?

The classic 5-5 rhythm (inhale 5s, exhale 5s) suits most practitioners. If you feel discomfort, start with a 4-6 rhythm (inhale 4s, exhale 6s), which promotes more relaxation thanks to the longer exhale. The 5-5-5 rhythm (inhale, hold, exhale) adds a hold that strengthens focus.

When to practice?

The best times to practice are:

• On waking: before checking your phone, to set the tone for the day
• Before lunch: to clear the morning's stress
• At the end of the day: to ease the transition toward evening and sleep
