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.
Shop CoolHed01Why cooling
Heat is part of sport. So is cooling.
When you train and compete, heat builds up. Cooling is one of the oldest and simplest ways to feel more comfortable. CoolHed brings steady, refreshing cooling to your head and neck. Freeze it, wear it, and go again.
03Built for training
Light, reusable, drug-free
No pills and no consumables. CoolHed is light enough to live in your kit bag and reusable session after session, so cooling can become a simple habit rather than a one-off.
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.04On the science
