Best bullshit and industry cutting phrase for better sleep: Follow the sun. Follow the sun for a fixed reference point for when to wake up, and for when to sleep, and guard yourself from artificial lights like it's your professional job. Bryan Johnson says to treat sleep like a professional job, and I take it further: break the standard industrial-factory based paradigm around sleep, work and life and say no to the clock based wellbeing-adversarial system.

edit: hours and minutes cannot replace our natural light-based circadian rhythm that evolved for millions of years entraining our hormones and energy cycles around the sun's light.
