Insomnia affects millions and can take many forms—difficulty falling asleep, frequent waking, early waking, or unrefreshing sleep. While sleep medications offer temporary relief, they don’t solve the root causes. Functional medicine looks at the full picture: cortisol rhythm, melatonin levels, inflammation, neurotransmitter imbalances, blood sugar instability, and even toxins or gut-brain dysfunction. By supporting the circadian rhythm and restoring nervous system balance, functional medicine offers lasting solutions for deep, restorative sleep without dependence on medication.
