You adjust back to recovery quickly.

So you're able to switch dynamically, very smoothly up and down to the environment.

And when you have a low heart rate variability, that is an indicator that we are not well recovered.

So our bodies struggle to switch on, and then when we switch on, it's hard to turn off.

And so that's what we see in PTSD and depression very commonly in people with chronic stress.

HRV is really a biomarker for vagus nerve activity.

So when we talk about the soothing sensations I was mentioning earlier, like Apollo, like soothing touch, like slow deep breathing, that increase vagus nerve activity reliably.

When you increase vagus nerve activity, you slow the heartbeat.

And when you slow the heartbeat, HRV goes up.

Got it.

And so as you're increasing vagus nerve activity, your body's recovery is increasing.

That's measured as heart rate variability.

Heart rate variability is not causal.

It just helps to predict when you have high vagus nerve activity, you're more likely to be more recovered, which means that all the benefits of recovery you can then predict.

So people are more likely to achieve peak performance regularly and consistently.

You're less likely to get sick.

You're more likely to recover from being sick.

And you're more likely to have higher longevity and health span, live a long, healthy life.

which is what we all want.

So now we actually have a biomarker for that.
