I hope the next 20-ish breaths are the most nourishing of your day.

4 THOUGHTS

1. Slow Breathing Synchronizes Heart and Brain Rhythms

Here is Leah Lagos, Psy.D., explaining a study where participants breathed at 6 breaths a minute for 5 minutes:

“They found that when subjects were in resonance, the resonance-induced oscillations seen in the heart were also observed in all nine brain regions. Their conclusion: Paced breathing at 0.1 Hz leads to large fluctuations in the diameter of blood vessels and, ultimately, improves the level of oxygenation of the brain, which aids cognitive and emotional control.”

- Heart Breath Mind

It’s another excellent reminder of the power of slow breathing to positively impact the heart, brain, and mind.

2. We Have More Control Over Our Biology Than We Might Think

“By manipulating our breath, body, awareness, feelings, and thoughts, we can decrease tension and stress. We can evoke or suppress specific emotions and focus our thoughts in ways that biologically influence other parts of the brain. From a neuroscientific perspective, this is astonishing…”

- Andrew Newberg, MD, and Mark Waldman, How God Changes Your Brain

A motivating reminder that, using voluntary control over our breath, body, and mind, we can positively influence essentially all aspects of our lives 👏

3. Your Mind Can Change Your Brain (and your life)

“The bottom-line, scientific take-home message is that you can use the focus of your mind to change your brain, to liberate your potential, and to improve your physiological well-being, your mental well-being, and your relational well-being.”

- Daniel Siegel, MD, The Mindful Brain

Building on the previous thought, we see just how powerful contemplative practices are for our overall well-being 🙏

"But when the going gets tough, the tough get sitting. This is precisely the time to apply our deepest skills and widest perspective—not to evade or deny the hard situation, but, on the contrary, to see it with clear eyes."
