A root-cause approach to sleep
Poor sleep almost always traces back to a handful of correctable systems, your circadian rhythm, your blood sugar, your cortisol curve, and the brain chemistry that switches you off at night. We find which ones are broken in your case and repair them.
Start here
Two hormones should move in opposite directions across the day. When they do, sleep is effortless. When they don't, it falls apart, and this rhythm is the first thing we look at.
When this rhythm inverts, low cortisol and high melatonin in the morning, high cortisol and low melatonin at night, you get the classic pattern: can't get out of bed, exhausted all day, then wide awake when your head hits the pillow.
"I can't sleep" usually means one of two distinct things, and they have different root causes. Knowing which one you have points straight at what to fix.
Wakefulness won't switch off
Waking at 2-4 AM
Whether you're asleep or awake comes down to a balance between signals that promote wakefulness and signals that promote sleep.
Not sure which signals are working against you? That's exactly what we map out, so you can tip the balance back toward sleep.

CPAP genuinely helps many people, but it raises an obvious question: why is it so common? Are our airways just built wrong? Usually not.
Carbon dioxide isn't just waste, it's the signal that tells your brain to breathe. When CO2 runs too low, that neural drive to breathe goes quiet, the muscles holding your upper airway open slacken, and the airway can collapse. That's a major contributor to obstruction.
Two things most commonly drive CO2 too low: stress and sympathetic dominance, which cause chronic over-breathing, and impaired mitochondrial function, since your mitochondria are what actually produce CO2. Fix those, and you're addressing the cause, not just forcing the airway open from the outside.
Address the cause, not just the symptomA common culprit
Nocturia is one of the most common reasons people don't stay asleep, and it's rarely just "too much water before bed." It's usually a signal that something upstream is off.
A hormone called ADH (vasopressin) is supposed to concentrate your urine overnight so you can sleep through without needing the bathroom. When you're waking up to pee, ADH is usually too low or your kidneys aren't responding to it, and a handful of correctable factors are behind that.
ADH production actually depends on vitamin C as a cofactor, so being low on it means less of the hormone that keeps you dry overnight.
Low sodium lowers your fluid osmolarity, which reduces ADH output, and it raises the stress hormones that push more fluid through your kidneys.
When potassium is low, the kidneys become resistant to ADH, so even normal levels stop working. An estimated 97% of people don't get enough.
Acidic urine irritates the nerves in your bladder and creates the "need to pee" sensation. People with overactive bladder and nocturia tend to have acidic urine.
Glycine acts as a calming neurotransmitter that inhibits bladder nerve contractions through the night, reducing urgency and nighttime trips.
Low calcium or vitamin D raises parathyroid hormone (PTH), and high PTH makes the kidneys less responsive to ADH, driving more nighttime urination.
Low carbon dioxide means less oxygen delivered to tissues, which activates the sympathetic nervous system, and that stress response drives more urination.
Your body clock times the overnight release of both ADH and melatonin. When the rhythm is off, that protective overnight surge of ADH never happens.
These are the levers behind that balance. Rather than sedating the system, we correct the inputs so sleep happens on its own. Tap any to expand.
Light is the master signal that anchors your entire body clock. Bright morning light hitting your eyes sets the rhythm for the day; darkness at night lets melatonin rise. When this is off, your body simply doesn't know when it's supposed to sleep.
A drop in blood sugar triggers noradrenaline, cortisol, and adrenaline, the exact hormones that keep you from falling asleep and jolt you awake around 3 AM. Overnight, your liver has to release stored glucose steadily to hold blood sugar; if it can't, you wake.
Cortisol should peak in the morning and bottom out at night. When chronic stress inverts that curve, you're wired at bedtime and depleted in the morning, often with an elevated, flattened rhythm that's hard to shut off.
The single most important switch for sleep is the balance between glutamate (excitatory) and GABA (calming). Too much excitatory tone, often driven by neuroinflammation and calcium flooding into neurons, keeps the brain from downshifting.
Gut and sleep problems travel together. A leaky or inflamed gut leaks endotoxin into the bloodstream, driving neuroinflammation that raises glutamate and noradrenaline, activates the stress axis, and fires up histamine-releasing mast cells. The gut's own nerves also signal the brain when irritated, like being pinched all night.
Every sleep signal is built from raw materials, and a shortfall in any one of them quietly keeps you awake. Melatonin synthesis alone requires several cofactors, and it's made in the mitochondria, so energy production matters too.
Histamine is a powerful wakefulness signal, which is exactly why antihistamines make you drowsy. Mast cells in the gut, body, and even the brain can release it through the night, keeping you in a lighter, more easily-disturbed sleep.
CO2 is the signal that tells your brain to breathe and keeps the airway muscles toned overnight. Chronic over-breathing from stress, and impaired mitochondrial function (which produces CO2), both push it too low, a major and overlooked contributor to sleep apnea and disturbed breathing.
We can run whatever labs your case calls for, a diurnal cortisol curve (four points across the day, not a single morning draw), fasting glucose and insulin, iron studies, magnesium and zinc, thyroid, and inflammatory or gut markers when relevant. But sleep is one area where the honest answer is that your experience matters more than any single number: exactly when you wake, whether you can fall back asleep, what you ate, and how your energy runs across the day tell us more than most panels. So we lead with a detailed picture of your nights and days, using labs to confirm and refine rather than to define. From there, you have full flexibility to go as deep into testing as you want.
