Why You Randomly Wake Up at 3AM

Around 3–4AM:

cortisol levels begin rising,
body temperature is lowest,
the brain becomes more threat-sensitive,
and emotional regulation weakens from fatigue.

This makes anxiety, intrusive thoughts, and sudden wake-ups feel much more intense.
Your brain isn’t broken at 3AM… it’s reacting exactly the way humans evolved to survive the dark. 🌙
Why anxiety, overthinking, and intrusive thoughts feel so much louder in the middle of the night.
