Sleep is when the repairs happen
Muscle, memory, metabolism and mood are all rebuilt overnight. Cut the night short, or keep it chaotic, and everything else runs on a deficit you can feel by 3pm. What you do around the night decides what you get back from it.
Find tonight's fix
Afternoon caffeine, a nightcap, a bright warm room: small things quietly steal your deepest sleep. You'll see what your nights are really giving you, the likeliest thief, and one change worth trying tonight, plus a calm flag if anything deserves a doctor's look.
