How to Reset Your Nervous System in 2 Minutes with Dr. Abbie-Smith Ryan

Strength means nothing if your nervous system never gets the signal to rest.

In this episode, I sit down with Dr. Abbie Smith-Ryan, exercise physiologist and professor at UNC Chapel Hill, to break down sympathetic versus parasympathetic states, why "central nervous system fatigue" shows up in athletes and high performers alike, and how recovery, not more output, is often the missing lever. We get into simple breathwork, the role of community and mindset in downregulation, and how nutrition, hydration, and hormones shape your capacity to handle stress at every life stage.

This isn't about doing less. It's about learning to periodize the push so you can sustain it.

What we explore:

- Sprint-then-rest cycles, and why sustainable performance depends on both.

- Sympathetic vs. parasympathetic states, explained in plain terms.

- Diaphragmatic breathwork, the two-minute reset that works anywhere.

- Burnout warning signs in high performers and athletes.

- Recovery tech, from hyperbaric chambers to guided vibration therapy.

- Hormones and midlife, and their direct impact on nervous system regulation.

The Gabby Reece Show

This is where I have real conversations with the people I find most worth listening to: scientists, athletes, coaches, parents, and thinkers who are doing the hard work of building a life that holds up over time. No hacks. No quick fixes. Just honest, practical conversations about performance, longevity, relationships, and what it actually takes to show up well at every age.

If you are here, you probably already know that health is not a destination. It is how you live. I am glad you are along for it.
