Why it is first
Growth hormone pulses in deep sleep. Testosterone is made overnight. Glymphatic clearance of the brain runs on slow-wave sleep. Insulin sensitivity drops after one short night. Start a protocol on top of broken sleep and you are paying for a signal the body cannot receive.
The history we actually take
Bed and wake times on work days and off days, and the gap between them. Shift pattern. Light exposure in the first hour and the last hour. Caffeine timing. Alcohol. Screen use. Snoring, witnessed apneas, morning headaches, nocturia. What the wearable says and whether it is believed.
What the labs add
Fasting insulin and morning cortisol pattern, ferritin for restless legs, testosterone and SHBG, thyroid, hs-CRP. A home sleep test when apnea is even a possibility; untreated apnea is the most common reason a hormone protocol disappoints.
Order of operations
- Anchor the wake time. Every day. That is the whole intervention for a surprising number of people.
- Morning outdoor light within an hour of waking; dim, warm light after sunset.
- Caffeine cut-off eight to ten hours before bed. Alcohol out of the last three hours.
- Treat apnea if it is there. Nothing else works until it is.
- Then, if indicated, the targeted tools: magnesium glycinate, glycine, low-dose melatonin timed correctly, and specific peptides where the registry data and the clinician agree.
First responders
Rotating shifts break every rule above by design. The plan for a firefighter or a nurse is different from the plan for a desk job: anchored sleep windows, strategic light, and honest conversation about what the schedule is costing. We have worn the uniform; we do not pretend the schedule is negotiable.
