HRV – What is it?

Why I Talk About HRV So Much (And Why It Matters for Your Nervous System Health)
By Maxine at The Roade House Yoga Studio

If you’ve spent any time in one of my classes or chatting with me over tea, you’ve probably heard me mention HRV—short for Heart Rate Variability—more than once. It might sound like a techy or clinical concept, but it’s actually one of the most useful indicators we have of how your nervous system is doing. And here at the studio, the nervous system is the heart of everything we do.

So what is HRV, really?

It’s the measure of the tiny variations in time between each of your heartbeats. That might sound odd at first—we often think of a steady, even heartbeat as ideal—but in fact, a healthy heart doesn’t beat like a drum. Instead, it shifts rhythm slightly in response to your breath, your thoughts, your environment, and your body’s needs.

These micro-adjustments are a sign that your body is flexible and responsive. A higher HRV means you’re more adaptable, resilient, and able to return to a calm state after stress. A lower HRV suggests the body might be stuck in a “fight or flight” pattern, even if you’re not aware of it.

Think of HRV as a window into how well your vagus nerve is functioning. This nerve runs from your brain to your gut and plays a huge role in regulating your parasympathetic nervous system—the “rest, digest and repair” branch that helps you feel calm, safe, and centred.

Here’s why I’m a bit obsessed with HRV:

• It shows how well you’re recovering from stress—physical, emotional, or even just a busy week.
• It helps you understand what supports your wellbeing. Gentle yoga, breathwork, nourishing meals, and rest tend to raise HRV.
• It’s measurable (if you like tracking with wearables like an Oura ring or Apple Watch) but also intuitive—most of us can feel when we’re more settled and grounded.

But you don’t need to track it with gadgets to benefit. The kinds of practices we do at the studio—like slow, supported movement, restorative yoga, hot stones, Yoga Nidra, and nervous system reset work—all naturally support your HRV and help tone the vagus nerve.

So why does this matter for you?
Because when your HRV is supported, you sleep better. You digest better. You think more clearly. You’re more emotionally resilient. And over time, you may feel more balanced, less reactive, and more connected to your body’s wisdom.

It’s one of those things I quietly build into all our sessions—not as a goal to “achieve,” but as a natural side effect of practising in a way that honours the body’s need to rest and recover.

So the next time you’re lying in Savasana or soaking in the stillness during a Friday night Yoga Nidra, know this: your nervous system is responding, your HRV is quietly improving, and your body is thanking you in ways you might not even realise.
