Everything is built on sleep.
The other half of performance — and the one most people get wrong. Temperature is the lever Helix pulls.
Circadian and temperature sleep tech
Helix Sleep covers temperature-regulating systems and circadian technology designed to deepen restorative sleep — because everything else you do, from training to cold to nutrition, is limited by how well you sleep.
What happens inside the body
Temperature regulation
A cooler core is one of the strongest triggers for deep sleep; active cooling and warming hold the optimal window.
Circadian light
Light timing sets the body clock that governs when you feel alert and when you wind down.
Repair during sleep
Deep sleep is when growth hormone peaks and the body physically repairs and adapts.
Consistency
A regular rhythm matters as much as duration.
What the research actually shows
A Stanford study (Mah et al.) had college basketball players extend their time in bed for several weeks. The result: faster sprints (16.2 to 15.5 seconds) and a 9% improvement in shooting accuracy on both free throws and three-pointers, plus better mood and reaction time. Sleep is when the body actually adapts — and temperature is one of the biggest, most controllable levers on sleep quality.
Why facilities invest
Protocols that work
Hold a cool sleep temperature and a consistent schedule.
Use light to anchor the body clock — bright by day, dim by night.
Treat sleep as the base layer every other protocol sits on.
Engineer better sleep.
