Postpartum sundown scaries: Understanding nighttime anxiety in new parents

The term ‘postpartum sundown scaries’ is used informally by new parents to describe waves of anxiety, dread, sadness, or uneasiness that intensify as evening approaches. While not a formal medical diagnosis, the experience is a recognized phenomenon driven by several physiological and psychological factors.

Key contributors to this nighttime anxiety include rapidly changing hormones, severely disrupted or fragmented sleep, and maternal hypervigilance. The uncertainty of how the night will unfold and feelings of isolation can further exacerbate these emotions. Additionally, postpartum insomnia and nighttime anxiety often create a reinforcing cycle where exhaustion is met with an inability to switch off.

To manage these feelings, experts suggest practical support such as sharing overnight responsibilities, preparing essentials in advance, and establishing small wind-down cues. However, medical attention is recommended if anxiety becomes persistent, severe, or interferes significantly with sleep.
