The autonomic nervous system controls stress and calm through its two branches — sympathetic (fight or flight) and parasympathetic (rest, digest, and connect). Chronic sympathetic dominance affects brain, gut, and immune function. Supporting vagal tone through breathing, movement, and connection helps children with autism shift from survival mode toward brain and body healing, regulation, and emotional safety.

Sleep problems in children with autism often stem from more than bedtime routines — they involve the gut, immune system, and brain. Neuroinflammation, histamine imbalance, and poor melatonin production can all disrupt rest. Learn how calming the nervous system, reducing inflammation, and supporting gut and immune health can help your child sleep deeply, restore brain repair, and wake happier.
