You're exhausted, but the moment your head hits the pillow your mind races — or you drop off fine and snap awake at 3am. That's not a "sleep problem" so much as a nervous-system problem. Your body is stuck in alert mode and won't power down.
Why stress wrecks sleep
Stress keeps you in low-grade fight-or-flight. Your heart rate and stress hormones stay slightly elevated, which blocks the deep, restorative sleep you actually need. So you "sleep" but wake unrefreshed — and being tired makes you more reactive to stress the next day. It's a loop.
A simple wind-down that works
- Hard stop on screens 30 minutes before bed. Bright light and doom-scrolling keep the brain switched on.
- Slow nasal breathing, 10 minutes. Try 4-7-8 (inhale 4, hold 7, exhale 8) ×4. This is the off-switch for the alert state.
- Magnesium in the evening and a warm bath or shower — both nudge the body toward "rest and digest."
- Cool, dark room. A slightly cold room improves deep sleep.
- Skip the nightcap. Alcohol knocks you out then fragments the back half of your night.
The daytime half nobody mentions
Good nights are built during the day: 10 minutes of morning daylight sets your body clock, strength training burns off the stress charge, and a lighter, earlier dinner means your body recovers at night instead of digesting. Fix sleep and almost everything else — energy, cravings, mood — gets easier.
