• Natural sleep cycle shift: Around 2–4 a.m., your core body temperature reaches its lowest point, and REM sleep transitions to lighter stages—making awakenings more likely.
  • Cortisol dip: Stress hormone levels are at their lowest, which can trigger subtle anxiety in sensitive nervous systems.
  • Liver & detox rhythm: In Traditional Chinese Medicine, 1–3 a.m. is liver time—a period of detox and emotional processing. Waking then may signal unresolved stress or frustration.
