Night Waking

Night waking is one of the most common sleep problems—and one of the most frustrating.

Some people wake up at exactly the same time every night. Others wake up multiple times, after only a few hours of sleep, or suddenly become fully alert in the middle of the night. In many cases, the wake-up itself isn’t the real problem. The underlying trigger is.

Night waking is often linked to stress, cortisol, blood sugar fluctuations, sleep timing, breathing issues, temperature regulation, or overly light sleep. Most people don’t wake up randomly. Their body is usually responding to a pattern that can be identified and improved.

The guides below are organized by symptom so you can quickly find the type of night waking you’re experiencing and learn what may be causing it.
