Concussion & CTE

CoolHed is changing the way we protect and recover the brain.

The Hidden Threat of Repetitive Head Impacts

Even without a diagnosed concussion, repeated blows to the head can cause microscopic damage that adds up over time. These repetitive head impacts (RHIs) are now linked to long-term changes in brain health, from memory loss and mood swings to chronic traumatic encephalopathy (CTE).

Even the hits you don't feel can leave an impact.

What Happens Inside the Brain

Every impact triggers a cascade of changes: axonal injury, glial activation, and the buildup of tau proteins, the same hallmarks seen in CTE. Over time, white matter weakens, neural connections break down, and inflammation spreads silently throughout the brain.

The Long Term Effects

What begins in the ring, field, or pitch can follow you for life.

The signs may not show up for years, but the damage continues beneath the surface.

  • Memory decline
  • Emotional instability
  • Depression and impulsivity
  • Cognitive impairment

CoolHed takes recovery beyond rest.

Using Selective Brain Cooling (SBC) and autonomic regulation, our protocol supports the body’s ability to restore balance where it matters most, the brain.

CoolHed is designed for:

  • Lowering brain temperature to stabilise neurons and reduce inflammation
  • Activating the vagus nerve to calm the nervous system
  • Supporting blood flow and oxygenation for faster mental recovery

The result? A calmer, clearer mind and a system that resets on a physiological level.

How CoolHed Works

Selective Brain Cooling (SBC)

Targets the carotid and jugular pathways to safely cool the brain, lowering metabolic demand and preventing further cell damage.

Vagus Nerve Stimulation

Gently stimulates the parasympathetic nervous system, your body’s natural “reset switch” to reduce inflammation and restore calm.

Diaphragmatic Breathing

Complements cooling by improving oxygen flow, supporting both focus and relaxation.

Together, these elements form a non-invasive neurotherapeutic protocol designed for athletes, professionals, and anyone exposed to cognitive strain or head impacts.

CoolHed may assist with:

  • Contact sport athletes (boxing, rugby, MMA, AFL, football)
  • Military and first responders
  • Coaches and medical professionals
  • Anyone seeking long-term protection for cognitive health

Whether you’re preventing future damage or managing the aftereffects of repeated impact, CoolHed helps you protect what matters most, your brain.

Concussion and CTE awareness is growing but recovery methods must evolve with the science.

CoolHed represents a new era of proactive brain care: measurable, modern, and built for real-world performance.
