Car engines use injections of cooled water when they need a burst of speed.  

Why can’t you use cold therapy when you need a pick-me-up?

Like a cold shower without the mess or a shot of coffee without the jitters, cold therapy delivered by the Head Cap offers:

• Increased alertness: By helping to stimulate hormone release, cold therapy promotes wakefulness and alertness.
• Elevated energy: Exposure to cold temperatures can help increase heart rate and blood pressure, boosting energy levels naturally.
• Improved mental focus: Cold therapy supports mental clarity and focus because it’s related to the release of adrenaline and other stress hormones that improve cognitive function.
  
  To put it simply: cold therapy wakes up your brain and re-energizes your body so you can fire on all cylinders.
