What this topic covers right now

Sleep is not a side quest. It is one of the primary systems that determines whether your attention holds, your mood stays usable, and your habits actually stick. On SelfGrowth, this topic should anchor practical, evidence-aware guidance about circadian rhythm, evening routines, light exposure, caffeine timing, recovery, and the difference between heroic sleep advice and sustainable sleep behavior.
A lead guide already exists here, so the best path is to start there and then widen out into the rest of the material.
