The CEO’s Nighttime Peeing Problem — Why “No Water After 7 PM” FailsPeeing at night is normal—the real issue is why you stay wide awake afterward.

This short episode unpacks what’s actually driving nighttime awakenings that look like bladder problems but are really nervous-system and hormonal timing issues. You’ll hear how vasopressin, melatonin, and stress-response systems interact to determine whether you fall back asleep—or stay alert for hours.

Key points:

Nighttime urination isn’t always about drinking too late—it often reflects blunted or mistimed vasopressin release.

Stress, light exposure, and age-related hormonal shifts can all weaken this overnight water-retention signal.

The bigger problem is loss of parasympathetic “sleep inertia,” the state that lets you drift back to sleep after waking.

Restricting fluids or adding sleep supplements won’t fix a circadian signaling error.

Listen for:How circadian hormone timing, vasopressin function, and nervous-system re-activation combine to create the modern midlife pattern of waking to pee and staying awake—and the practical systems approach that resolves it.
