Vagus nerve, overused, altered immune system function, and now you got sick or got more sick than you should have got because of that overall stress response you were less resilient to. Now, another example of that is a really complicated study, but it was so beautiful. I wanted to point it out. What they looked at here was this resilience or what's called reactivity marker.

And so what they found is kind of getting to the end of the paper here was when you were in the state of low HRV, sympathetic drive, That gave you higher sleep reactivity to stress. Meaning when we expose you to the same stressor, you had a exaggerated sleep response. In this case, a bad sleep response. That's exactly what we're talking about.

So the same thing happened to you when you had a higher HRV, didn't affect your sleep. Now, when we give that thing to you and you have a low HRV, it affects your sleep a lot. That's higher reactivity. That is being less resilient to the same stressor. So same stress, big response. This is in circular, right? Because we also know at the same point, less sleep or worse sleep,

increases your risk of all kinds of problems. And in this specific paper, the problem that they're looking at was depression symptoms. So the lower amount of sleep increased the risk of experiencing higher depressive symptoms. Many actual examples of this, but that really does, again, encapsulates what I'm trying to talk about here. It's not just up or down.

It is being more resilient to everything that happens in your life. And our autonomic nervous system is a great tool to measure and pay attention to for that. So if that doesn't convince you, I don't know what will, but I'm assuming at this point you're all on board. So how do you actually measure it? Let's talk about different ways where you can actually investigate your HRV level.

Hydration is critical to performance, both physical and mental performance. Countless studies have shown that even a slight degree of dehydration, even as small as 1%, can lead to decreases in physical output and mental performance.

Countless studies have shown that even a slight degree of dehydration, even as small as 1%, can lead to decreases in physical output and mental performance.

We also know that electrolytes are critical to proper hydration, which I've been harping on for years. But you can't do that, proper hydration, by only drinking water. You need to get the right amount of electrolytes in the right ratios, and that's why I'm a huge fan of Element.

In fact, many of you will probably remember that I featured Element in my YouTube series on optimizing hydration nearly five years ago. I featured Element in these videos because their blend of 1,000 milligrams of sodium 200 milligrams potassium, and 60 milligrams of magnesium really is unique and different than any other electrolyte on the market, and it has great scientific support.

Many studies have shown that anywhere between 10 to up to 40% of supplements have accidental contaminants, intentional alterations, mislabeling, or other serious issues. But Momentus is different. I literally spent years vetting the company, their products, and leadership team before personally officially partnering with them in 2023.
