Your core body temperature also plays a key role. If it doesn’t stabilize properly, sleep becomes less deep and you’re more prone to micro-awakenings. The slightest change—a duvet that’s too warm, pajamas that are too thick—is sometimes enough to wake you up.
When stress creeps into your nights
Ah, the infamous 2 a.m. wake-up call… It’s more common than you think! At this hour, our nervous system is particularly receptive. Emotions suppressed during the day resurface, like bubbles rising to the surface. Nothing abnormal: it’s your brain sorting, organizing, and calming you down.
