Find Calm in Seconds.
Activate your body’s natural calming system with targeted cooling.
Help Your Body Find Balance
Anxiety relief isn’t about forcing yourself to calm down — it’s about helping your nervous system reset. What if you could interrupt anxiety at the physical level, without medication, in under two minutes? The physiology is well understood, and the response can be fast.
Cryo-1 is designed to activate the body’s natural calming pathways using targeted cooling of the palms and neck.
- Rapid calming response in 60–90 seconds
- Helps lower heart rate during stress or panic
- Reduces intensity and duration of anxiety spikes
- Portable. Rechargeable. Drug-free. No mess.
Vagus nerve cooling can help reset your nervous system without drugs or medication.
Anxiety Hijacks the Body
Anxiety isn’t just “in your head.”
When anxiety hits, the body enters fight‑or‑flight mode:
- Heart rate increases
- Breathing becomes shallow
- Muscles tense
- The nervous system stays stuck in a high-alert state
Coping tools like breathing, grounding, or meditation work — but they often take time. In the middle of a panic spike, many people need something physical to help the body stand down.
Cooling Activates the Body’s Calming System
Targeted cooling has been shown to influence the parasympathetic nervous system, which is responsible for rest, digestion, and calm.
Research shows:
- Cold applied to the side of the neck can lower heart rate by 5–10 beats per minute
- Cooling dampens sympathetic (fight‑or‑flight) nervous system activity
- The body shifts out of high alert and toward balance
This response is linked to stimulation of the vagus nerve, a major pathway that helps regulate stress and emotional state.
Cryo‑1
Cryo-1 delivers controlled cooling in a precise, repeatable way — without ice, water, or discomfort.
Unlike improvised cold packs, Cryo-1:
- Maintains a safe, optimal temperature range
- Can be applied to the side of the neck or held in the palms
- Works quickly without numbing or shock
- Fits easily into daily life
It’s designed to help interrupt anxiety at the physical level — right when you need it.
How do I use Cryo-1 for anxiety?
Apply Cryo-1 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 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 is it 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-1, on the other hand, applies
controlled “cool‑not‑cold” cooling that keeps blood flowing, removing
heat faster and more effectively.
How long does Cryo-1 take to work?
Most users feel results within 60–90 seconds.
How long does the cooling effect last?
A short session with Cryo-1 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-1 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.
Cryo-1 is a palm cooling and warming device designed to boost physical performance and support heat recovery.
Cryo-1 is designed to help athletes perform, train and recover more effectively; provide rapid comfort for women during hot flashes; and anyone recover faster from heat stress (including kids playing sport).
Cryo-1 is compact, rechargeable, and easy to use.
