DSPD means your internal clock is set 3-4 hours later than average.
Not broken. Not dysfunctional. Just delayed.
Most people start feeling sleepy around 10 or 11PM.
Their brain is ready to shut down.
Yours isn’t.
That’s why forcing earlier bedtimes never held.
And why mornings have always felt like waking up in the middle of the night.
Millions of people live with this same pattern.
Most are never diagnosed.
For a lot of people, this isn’t just a phase or a bad habit.
It’s something they’ve lived with for as long as they can remember.
And often, delayed sleep timing shows up far more often in people with ADHD.
Research shows delayed circadian rhythm is far more common in adults with ADHD, even when they’ve never heard the term DSPD.
