Waking up in the middle of the night to pee — again? Tossing and turning with restless energy? Or worse — feeling shaky, sweaty, or foggy-headed upon waking?

You might not realize it, but your blood sugar levels overnight could be the hidden culprit.

When blood sugar drops too low (or spikes too high) while you sleep, your body panics. It releases stress hormones like cortisol and adrenaline to bring glucose back up — but these same hormones disrupt deep sleep, increase nighttime urination, and can leave you exhausted by morning.

And if you have insulin resistance or prediabetes, this cycle becomes even more common — especially due to the “dawn phenomenon”, where natural hormone surges cause blood sugar to spike at dawn.

But here’s the good news: what you drink before bed can help stabilize your blood sugar all night long — leading to deeper sleep, fewer bathroom trips, and better energy in the morning.

Let’s explore 7 science-backed bedtime drinks that support balanced blood sugar — starting tonight.
