@adhdvision: Can you relate? - part 17 If you have ADHD instead of sleeping on your hand like a boring person, you often like to curl them up and sleep on your wrists not because it’s more comfortable but because your brain is naturally under-stimulated when it rests and unique sensory input like this can help regulate your nervous system. This is also why you like to tap your fingers, crack your knuckles or rock back and forth constantly, since the right kind of stimulation actually helps your brain to calm down and even focus. What looks “restless” to others from the outside is your way of calming the chaos on the inside.
