Why Do I Wake Up With A Headache Common Causes From Posture To Hydration
Your brain panics, wakes you up just enough to gasp for air, and then you go back to sleep. This can happen hundreds of times.

Ever sleep in on a Saturday and wake up with a pounding head? That’s called a weekend headache.
When you sleep late, you go through extra cycles of REM (dream sleep). Your brain is super active during REM, and that activity can trigger a headache.
It’s ironic: too much rest can actually hurt you. Your brain is like a toddler who gets cranky when their nap runs overtime.
