Three cooling settings (12–16 °C / 54–61 °F) and three warming settings (95–109 °F) for both performance and comfort.
Long Battery Life
80-175 minutes (cool/warm modes @ maximum setting) of use on a single charge, powered by USB-C rechargeable battery.
Designed by Science, Built for Life
Every element of cryo-1 is engineered for performance and convinience — from the curved active surface that targets your palm’s AVAs to the intuitive controls and long-lasting battery.
From workouts to hot flashes, long shifts to anxious moments, it’s fast, portable, and effortless — so you’re always in control.
Active Surface (Cool & Heat)
Instant Relief at Your Palm.
Large contoured surface engineered for maximum skin contact. Rapidly transfers cold or hot thermal energy through your palm’s AVAs to regulate core body temperature within minutes.
Ergonomic Design
Fits Every Hand.
Curved, compact design (about the size of a Red Bull can) conforms naturally to your palm. Easy to hold, lightweight at 13 oz, and quiet enough for discreet use.
Charging Port
Fast & Universal Charging.
USB-C port for quick recharges. 90 minutes of battery life per charge keeps you covered through workouts, hot flash episodes, or outdoor fun.
Battery Indicator & Controls
Simple, Clear & Reliable.
LED display shows remaining battery life at a glance. Intuitive buttons cycle between hot and cold modes, making it easy to use anywhere.
THE SCIENCE
Your body has built-in “radiator” zones in the palms of your hands.
By delivering precise, conductive cooling or warming to these areas, Cryo-1 is designed to help quickly adjust your core temperature and signal your nervous system to relax.
In just 60–90 seconds, you can lower body temperature, ease hot flashes, warm up during chills, reduce fatigue, or calm anxiety.
Use cases
Boost Athletic Performance
Stanford-led studies prove that cooling the palms between sets can dramatically extend performance.
In controlled training programs, athletes increased total work volume by up to 144%, improved strength gains by 22%, and added minutes of endurance even in extreme heat.
Cryo-1 is specifically designed to help you push harder, recover faster, and keep improving.
Ease Hot Flashes & Chills
For women experiencing menopause, sudden hot flashes, night sweats and chills can be exhausting and disruptive. In real-world testing, 100% of our users reported noticeable relief, with many cutting episodes from 10 minutes down to about 60 seconds.
Cryo-1's cooling mode is designed to rapidly cool your core, reducing excess heat during hot flashes, while its warming mode gently restores circulation and comfort during chills.
These results align with clinical research showing that targeted palm temperature therapy significantly eases vasomotor symptoms. For sufferers Cryo-1 can deliver discreet, drug-free relief anytime, anywhere.
Beat Heat Stress Outdoors
Heat fatigue affects everyone - from golfers and pickleball players to spectators at outdoor events.
Professional sports teams rely on palm cooling to keep athletes in the game; Cryo-1 puts the same technology in your pocket.
By lowering your core temperature through AVA-rich skin, Cryo-1 can help you stay safe, comfortable, and active longer under the sun.
Ease Stress & Anxiety
Anxiety can trigger racing thoughts and a pounding heart.
Cooling the side of the neck with Cryo-1 can activate the Vagus nerve, which signals your body to shift out of fight-or-flight and into calm. Clinical studies show that brief cold application reduces heart rate and stress markers within minutes.
With Cryo-1, you can carry calm with you wherever life takes you.
How to use Cryo-1
Power management
Battery check: Tap either button once. The four white LEDs show remaining charge:
4 lights = 100% | 3 = 75% | 2 = 50% | 1 = 25%.
When charge drops below 10%, 4 lights flash; below 5%, the device powers off automatically to protect the battery.
Charging: Use the supplied USB-C cable. Full charge takes about 4 hours.
Using Cool & Warm Modes
Power on: To power on, press and hold the Cool or Warm Button for 2 seconds. Cryo-1 will start at maximum power for the selected mode.
Cool Mode: Three blue lights indicate maximum power. Briefly press button to cycle: High (12°C / 54°F) → Medium (14°C / 57°F) → Low (16°C / 61°F) → High.
Warm Mode: Three orange lights indicate maximum power. Briefly press button to cycle: High (109°F / 43°C) → Medium (102°F / 39°C) → Low (95°F / 35°C) → High.
Power off: Press and hold the active button for 2 seconds to power off.
Auto-off: Cryo-1 runs for 20 minutes per cycle and can be restarted immediately.
Use Recommendations
When Cooling: Cryo-1 can be used immediately after powering on, but for peak efficiency during workouts, turn it on a few minutes beforehand so it reaches target temperature. Use in 1–3 minute intervals in direct contact with the palm for rapid recovery and core temperature control.
Cryo-1 may also be used on the side of the neck (near the jugular artery) for reduction of heart rate. Safe for longer sessions if desired.
When Warming: Ideal for recovery or circulation between cold intervals. Use continuously or as needed; no time restriction.
Safety: The device is designed for unlimited use. Both cooling and warming modes are safe for extended or repeated sessions.
