Watching this video on rituals of successful entrepreneurs most of them have the habit of making themselves wake up very early. The presenter wakes up at 5am.
Waking up early is often promoted as a way to increase drive, productivity, motivation, mental clarity and take charge of your life, ie increase dopamine which should have beneficial downstream effects on your whole metabolism.
I've always shunned the use of an alarm clock thinking it would be healthier to wake spontaneously, but perhaps it aint. Anyone experimented with intentionally waking up early and what was your experience?
