Study 03 · Cranial Cooling

One platform, two pillars.

A single cranial platform — the HALO unit — directed to two ends, concussion and sleep. Device-agnostic and clinician-governed throughout.

The HALO CTP — Temp°IQ™ cranial thermal pack
Audience: sports-medicine clinicians, athletic trainers, researchers/labs, sleep specialists, and partner institutions — plus athletes/families and leaders.
Job: Learn (educational hub) → Engage (study enrollment / collaboration) → Advance.
Primary action: route partners into the concussion study; route sleep interest to the sleep application.

Pillar 1 · Concussion Management

An educational hub, and a study.

Learn

The educational hub

A place to read and learn: what a concussion is, how it’s assessed, what ImPACT and Sway are, and how blood-based biomarkers fit in.

The Concussion Cooling Study

Short-term arm — symptom trajectory, acute biomarkers (GFAP / UCH-L1), instrumented thermal data.

Long-term arm — cumulative head-impact exposure, NfL, serial cognition.

Device-agnostic and clinician-governed.

Pillar 2 · Sleep Management

The same architecture, applied nightly.

The same peri-cranial vascular cooling — engineered for sleep. The case is direct, and it rests on established physiology:

  • Sleep onset depends on a coordinated fall in core and brain temperature.
  • Insomnia is increasingly understood as frontal cortical hyperarousal.
  • Published research indicates that surface cooling over the temporal artery and carotid sheath can lower brain temperature through selective brain cooling, without the shivering or arousal that whole-body cooling can provoke.
  • In a randomized controlled trial, frontal cerebral cooling was reported to reduce sleep-onset latency without sedative effects. These findings come from the published literature and are not claims about this device.

One platform — studied for concussion and applied, on the same principle, to sleep.

Advance

Toward an improved cranial device.

Recovery study (short + long) and the sleep indication → an improved cranial device and protocols.

Governance. Cranial work is device-agnostic and clinician-governed; minors require guardian consent. Names appear only in an athletics context with consent, never on the clinical side.
Regulatory note. Descriptive, not diagnostic. The sleep application is consumer-wellness framing and is not a medical (insomnia) treatment claim; nothing here is a treatment claim or a statement of FDA clearance.
