Insomnia
Insomnia is a brain that cannot shift into safety at night. We ask why your brain stays alert, rather than sedating it, and look at rhythm, blood sugar, histamine, and the nervous system.
What you may be noticing
You are exhausted all day, then wide awake when your head touches the pillow. Or you fall asleep easily and wake at 2 or 3 in the morning with a racing mind. You watch the clock, calculate the hours left, and dread tomorrow. Caffeine carries you through, and the cycle repeats.
Why it is rarely one thing
Sleep is not something you can force. It is something the brain allows when it judges conditions to be safe and the internal clock signals night.
So the central question is not how to sedate the brain. It is why your brain stays alert. The clock is set by light, darkness, meal timing, and movement. Safety is judged by the autonomic nervous system, cortisol rhythm, blood sugar, pain, breathing, histamine, and hormones. It also helps to know which part of sleep is affected: falling asleep, staying asleep, or reaching deep and dream sleep. Each points toward different drivers.
Deep sleep is when your brain clears metabolic waste through the glymphatic system, a process first mapped in animal research and now being studied in people, and when memory consolidates. Restoring sleep is foundational to nearly everything else, which is why sleep and circadian rhythm sit in the first phase of every plan I build.
If you take a sleep medication, keep taking it as prescribed. Any change belongs with your prescribing physician, since several sleep medications need a slow, supervised taper.
Patterns we look for
- Autonomic hyperarousal: internal shaking, light and sound sensitivity, a body braced for threat.
- Cortisol rhythm. A high evening cortisol or a surge overnight wakes you.
- Blood sugar drops at night, which trigger adrenaline and a 3am waking.
- Circadian rhythm: morning light, evening screens, and meal timing.
- Hormonal transitions, including progesterone decline in perimenopause and night sweats.
- Histamine excess and mast cell activation, which promote wakefulness.
- Neuroinflammation, including after mold exposure or chronic infection.
- Sleep apnea and upper airway resistance, which fragment sleep without obvious snoring.
- Restless legs, often linked to low ferritin.
- Magnesium, vitamin D, and the building blocks for melatonin and GABA.
- Pain, thyroid excess, and racing thoughts.
How I evaluate it
A comprehensive functional neurological exam assesses autonomic balance, brainstem function, eye movement tolerance, and signs of a stress system stuck in the on position. In a highly sensitized nervous system, I keep testing and exercises gentle, because intense visual or vestibular work can amplify symptoms.
Functional labs may include a cortisol rhythm, fasting glucose and insulin, ferritin, magnesium, vitamin D, a thyroid panel, sex hormones when relevant, histamine markers, and inflammatory markers. A sleep study is recommended when apnea is suspected, especially with snoring, morning headaches, or daytime sleepiness.
How we address it
- Reset the clock: water and outdoor light soon after waking, a consistent wake time, gentle morning movement, and dim evenings with screens off well before bed.
- Stabilize blood sugar with a protein-first breakfast, a short walk after meals, and dinner well before bedtime.
- Calm the nervous system with a small, precise evening routine: slow nasal breathing with a longer exhale, slow smooth eye pursuits, gentle neck mobility, and a guided release of face, jaw, and shoulders.
- Address cortisol rhythm, hormones, histamine, iron, airway, and inflammation when they contribute.
- Quiet a racing mind with brain-based strategies that strengthen frontal regulation.
Sleep is not lost. It is waiting for the right conditions to return.
