Sleeping through the night without interruptions is crucial for feeling refreshed and productive. However, many people find themselves waking up between 3:00 AM and 5:00 AM and struggling to fall back asleep. This pattern has both historical and physiological significance.

This period is sometimes called the “hour of the wolf,” a term popularized by Swedish filmmaker Ingmar Bergman, who described it as the time between night and dawn when sleep is deepest, nightmares feel most vivid, and many people pass away. Swedish folklore also links this hour with a higher likelihood of births and deaths.

During these early morning hours, the body reaches its lowest physiological state—core temperature, blood pressure, and metabolism slow down as part of the circadian rhythm. For those prone to anxiety, this phase can amplify negative emotions, making it harder to stay asleep.

Many cultures associate this timeframe with supernatural activity, often referring to it as the “witching hour.” Whether influenced by folklore or biological processes, waking up at this time can feel unsettling, especially for those who experience anxiety.
