Why dark evenings make mornings harder
Your circadian rhythm takes its main cue from light. Evening darkness should trigger melatonin and pull you toward sleep — but artificial light after sunset blunts that, so your clock slips later and later. The alarm you set does not move, so it starts landing in deep sleep. The answer is managing light, covered in light exposure and sleep and fixing a drifted schedule.
