Even the deepest sleepers experience brief moments of wakefulness throughout the night. These tiny interruptions—called microawakenings—are completely normal and often go unnoticed. In fact, most people have dozens of them every night.
But while microawakenings are a natural part of the sleep cycle, they can become problematic when they occur too frequently or last too long. When that happens, they can fragment sleep, leave you feeling unrefreshed in the morning, and subtly contribute to daytime fatigue, mood changes, and cognitive fog.
Understanding what microawakenings are, why they happen, and how they affect your rest can help you make sense of symptoms you may not even realize are sleep-related.
