In this YouTube short, Nyree Penn explains how constant high‑intensity stimulation—especially late‑night workouts—can deplete dopamine and push the nervous system into a state of hypervigilance and hyperarousal. She describes the paradox of lying in bed for the recommended 8‑hour sleep window yet feeling wide awake, resulting in a "wired and tired" condition. The speaker warns that the relentless "go, go, go" mindset, combined with nighttime training, disrupts sleep architecture and can lead to chronic fatigue despite apparent effort.

Chapters

Dopamine's a good thing, but you can go into dopamine depletion. And so it's like constant, constant, constant go, go, go. So just because, all right, our training schedule says that we need to get some sleep between the hours of 10 and 7, I need 8 hours, I need 6 hours. All right, I'm in bed and I'm wide frickin' awake. I'll be wired and tired. A lot of guys work out at night, right? They're on a constant level of overdrive, hypervigilance, hyperarousal, fight, fight, fight, you know, grind, grind, grind, no sleep.
