Tired body, busy brain

Feeling exhausted but unable to fall asleep usually comes down to a nervous system that's still switched "on." Your body is ready to rest; your mind hasn't gotten the signal.

Common culprits

Late screens and bright light, caffeine too late in the day, an inconsistent sleep schedule, and going straight from a stressful evening to bed all keep you keyed up when you'd rather be winding down.

The fix is a transition

Sleep works better when there's a runway into it, dimmer light, less stimulation, and a consistent wind-down. Gentle support like magnesium can fit into that routine, but the routine itself does most of the work.
