Take Control of Hot Flashes.
Science-backed palm cooling is designed to calm sudden heat spikes and restore comfort — without hormones.
Taming the 'Hot-Flash'
You can calm a hot flash quickly, without hormones or medication. It may sound too simple, but the physiology is real.
Cryo-1 is designed to help stabilize sudden heat spikes by safely removing excess heat from your body core. It provides:
- Fast relief when a hot flash begins
- Less intense heat surges
- Improved comfort at night
- Reduced anxiety around unpredictable symptoms
Some women in our test group experienced significant reduction in their hot flash symptoms with events dropping from an experienced 10 minutes to around 60 seconds when using Cryo-1.
Hot Flashes Start Long Before Menopause
Hot flashes don’t suddenly appear at menopause.
For many women, they begin during perimenopause — a transition phase that can last 10 years or more before menopause officially occurs. This phase often starts in a woman’s late 30s or 40s, and it’s far more common than most people realize.
Here’s what’s happening in simple terms:
- Estrogen levels rise and fall unpredictably
- The brain’s thermostat (the hypothalamus) becomes overly reactive
- Blood vessels suddenly open, sending heat to the skin. Heart rate increases. Sweating starts.
The result is a hot flash that feels sudden, intense, and disruptive — even though nothing external has changed.
Despite affecting millions of women, perimenopause is rarely discussed openly. That silence leaves many women feeling unprepared, confused, or dismissed when symptoms begin.
Hormonal Chills Are Also A Thing
Not all temperature symptoms during perimenopause feel hot.
Many women experience sudden chills, cold waves, or shivering — sometimes immediately after a hot flash, sometimes on their own. These chills can feel confusing and even alarming, especially when the room temperature hasn’t changed.
Here’s why this happens:
- The same fluctuating estrogen levels disrupt the brain’s thermostat
- After a heat surge, the body can overcorrect in the opposite direction
- Blood vessels constrict too quickly, pulling warmth away from the skin
The result is a sudden feeling of being cold, shaky, or unable to warm up — even under blankets.
Why Palm Cooling & Warming Works
Our palms are one of the body’s fastest heat‑exchange zones.
Specialized blood vessels called arteriovenous anastomoses (AVAs) allow heat to move rapidly from circulating blood to the outside world.
When the palms are cooled:
- Heat is pulled directly from the bloodstream
- Core temperature begins to drop
- The body’s overactive cooling response starts to settle
When the palms are gently warmed:
- Blood flow increases at the surface
- Warmth is returned to the circulation
- The body’s excessive cooling response begins to normalize
Instead of fighting your body, controlled palm cooling or warming helps it rebalance.
Cryo‑1
Cryo-1 brings controlled, science-backed palm cooling & warming into a compact, easy-to-use device designed for real life.
Unlike ice packs, fans, heating pads or invasive treatments, Cryo-1:
- Targets the palms at the optimal cooling and warming range
- Works in 60–90 seconds
- Is quiet, discreet and portable
- Requires no water, ice, or preparation
This isn’t masking symptoms — it’s helping the body regulate its temperature naturally.
How do I use Cryo-1 for Hot-Flash relief?
At the onset of a hot flash, hold Cryo-1 in your palm on maximum cool 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 around 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.
Think of it like letting an engine cool down so it runs smoother and with more power on the next lap.
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 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.
