Introduction

Do you ever feel like your brain suddenly becomes more active at night?

For adults and children with ADHD, bedtime doesn’t always mean rest. Instead, it often triggers racing thoughts, overthinking, and restlessness.

You may feel physically tired, but your mind just won’t slow down.

This isn’t laziness or poor habits it’s how the ADHD brain works.

During the day, your brain is constantly managing:

  • Noise
  • Tasks
  • Distractions

At night, when everything gets quiet:

  • External stimulation drops
  • Your brain turns inward
  • Thoughts become louder

This is closely linked to dopamine regulation and sensory processing.
