General Product Info
What is Cryo and how does it work?
Cryo-1 is a handheld cooling device that uses precise “cool-not-cold” conductive cooling through the palms. These areas have special blood vessels and nerves that regulate heat and stress. As the blood in your palms cools, it circulates through the rest of your body, lowering core temperature and reducing the buildup of heat and stress signals. This process helps you feel relief in seconds while supporting overall recovery and performance.
How is Cryo different from an ice pack?
Ice is too cold to effectively cool the body without causing blood vessels to constrict. This slows circulation and limits heat transfer.
Cryo, on the other hand, applies controlled “cool‑not‑cold” cooling that keeps blood flowing, removing heat faster and more effectively.
Who can use Cryo?
Cryo is designed for athletes, women experiencing hot flashes, outdoor enthusiasts, people attending concerts or sporting events, and anyone looking for natural stress relief. Always consult your doctor if you have medical conditions.
How long does Cryo take to work?
Most users feel results within 60–90 seconds. Some effects—like lowering core temperature or calming anxiety—are almost instant.
Device Features
How long does the battery last?
Cryo has a battery life of 80–90 minutes on maximum cool or 175 minutes on maximum warm. This will give you dozens of short sessions per charge.
How do I recharge Cryo?
Cryo fully recharges via USB-C in about 5 hours.
Does Cryo require ice or water?
No. Cryo uses built-in cooling modules—no ice, water, or prep required.
Is Cryo noisy?
Cryo is whisper-quiet at under 47 dB, comparable to a soft computer fan.
Science & Safety
What does the science say about palm cooling?
Stanford-led research shows palm cooling can increase training volume by up to 144%, extend endurance in heat by 43%, and shorten hot flashes from 10 minutes to under 60 seconds.
Is Cryo safe for people with medical conditions?
Cryo is generally safe for healthy users. If you have heart disease, circulatory disorders, or other medical conditions, consult your physician before use.
Can Cryo replace medication for hot flashes or anxiety?
Cryo is a non-drug alternative that may help reduce symptoms, but it should not replace prescribed treatments without your doctor’s advice.
Why is “cool-not-cold” better than ice?
Cooling at 50–60 °F avoids vasoconstriction, allowing continuous blood flow and faster heat transfer compared to ice.
Usage & Performance
How do I get maximum performance from the Cryo-1 Device?
For best results, we suggest turning Cryo-1 on a couple of minutes before you need it. We recommend setting it to maximum power—three cool lights for cooling or three warm lights for warming—and allowing it to run on its own for 1–3 minutes. This lets the device reach its optimal temperature faster than if it’s being held immediately.
That’s not to say you won’t feel relief right away when using it handheld, but pre-running ensures the coldest or warmest effect.
Each cycle runs for about 20 minutes, giving you plenty of time to enjoy a session and then turn it off before the cycle completes.
How do I use Cryo for workouts?
Hold Cryo in your palm for 1–3 minutes between sets or intervals.
You should feel an immediate sense of coolness throughout your body, but the real benefit comes in your next effort—whether that’s a heavier lift, a sharper sprint, or a steadier performance.
This brief cooling lowers core temperature and helps reverse the buildup of heat and acidic byproducts in working muscles, restoring enzyme efficiency and contraction strength so you can perform stronger on the very next set.
Think of it like letting an engine cool down so it runs smoother and with more power on the next lap.
How do I use Cryo for hot flashes?
At the onset of a hot flash, hold Cryo in your palm for rapid relief. You should feel a cooling sensation almost immediately as excess heat is drawn from the bloodstream, which helps blunt the intensity of the episode.
In user testing, many reported their hot flashes shortened from ten minutes to under one minute.
For nighttime use, keeping Cryo by the bed allows quick application during night sweats, helping restore comfort and return to sleep faster.
This response is consistent with clinical research showing palm cooling significantly reduces the severity and duration of menopausal vasomotor symptoms.
How do I use Cryo for anxiety?
Apply Cryo to the side of the neck in cycles of 30–60 seconds on and 30–60 seconds off. Repeat this on–off pattern until you notice your heart rate decreasing and the stress symptoms beginning to abate.
This patterned cooling activates the vagus nerve more effectively and helps the body transition from fight-or-flight into a calmer state.
How long does the cooling effect last?
A short session with Cryo can deliver benefits that last well beyond the moment of use.
For athletes, cooling the palms between sets or sprints can sharpen the very next effort and sustain performance for several minutes to several hours.
For women using Cryo to stop hot flashes, a single session often ends the episode entirely and provides comfort until the next occurrence.
In this way, the relief from one use can carry through workouts, daily activities, or extended periods of calm, making each session remarkably effective.
