Tired but Wired: the Hyperarousal Insomnia Pattern

For the body that is exhausted at night but the mind that will not stand down.

If the assessment placed you here, this is the pattern we hear about most often. The lights are off, the body is shattered, and the system is still switched on: racing thoughts, a tight chest, the day's loose ends rehearsing themselves, the clock checked at 1 am, 2 am, 3 am. By the morning the deficit is real. The next night does the same thing.

What is actually happening in hyperarousal insomnia

Hyperarousal insomnia is the wakefulness signal failing to step back at the end of the day. Evening cortisol stays elevated when it should be falling. The cognitive system stays in problem-solving mode when it should be releasing it. Muscle tone, heart rate variability, breathing — all of it remains in daytime configuration when it should be in night-time configuration. The result is the paradox: the more tired you are, the harder it is to fall asleep.

This is not a sleep-deficit problem. It is an arousal problem. The therapeutic logic, then, is to unwind the arousal in stages — easing the evening cortisol response and the racing mind first, then settling the body at lights-out.

The Slumbr approach

Hyperarousal needs more than one signal. Slumbr's hyperarousal protocol is a two-phase, physician-formulated approach built around four non-prescription ingredients — saffron, L-theanine, glycine and magnesium glycinate. Phase I, about an hour before bed, uses saffron to soften the elevated evening cortisol response and L-theanine to quieten the racing mind. Phase II, at lights-out, uses glycine to settle the body and magnesium glycinate to support the body's natural wind-down. Each phase is timed to a different part of the evening, so the protocol works with your wind-down rather than asking a single dose to do everything at once.

Slumbr currently supplies two of the four from this protocol: L-Theanine 300 mg capsules for Phase I and Glycine bedtime powder for Phase II. For the evidence behind the other two, read our Journal reviews of saffron for sleep and magnesium glycinate for sleep.

When prescription is the right next step

If your sleep difficulty has lasted more than three months, comes with significant daytime impact, or has not responded to behavioural and non-prescription support, a specialist consultation discusses prescription pathways. The mechanism-aligned option for hyperarousal is the dual orexin receptor antagonist class — these medications quieten the brain's wakefulness signal at night, so sleep arrives because the wakefulness has stepped back, not because you have been sedated on top of it. No dependence. No rebound. Low next-day impairment.

How telephonic consultations work

Within the wider plan

For chronic insomnia, Cognitive Behavioural Therapy for Insomnia (CBT-I) is the leading evidence-based approach. Where it fits your situation, the Slumbr consultation can discuss or signpost CBT-I — many patients do best with CBT-I alongside the formulation or a prescription, addressing different layers of the same problem. Both the American Academy of Sleep Medicine's 2021 clinical practice guideline and the European Insomnia Guideline 2023 recommend CBT-I as the first-line treatment for chronic insomnia.
