Waking up at the same time every night with anxiety is often related to your natural sleep cycles and circadian rhythms. Around 3-4am, your body naturally experiences a dip in core temperature and changes in hormone levels that can trigger wakefulness.
If you're already stressed or anxious, these natural fluctuations can cause you to wake up in an anxious state. Creating a consistent sleep schedule, managing daytime stress, and having a plan for middle-of-the-night anxiety can help break this pattern.
