I get panic attacks. When I feel it coming on, I cool my vagus nerve on my neck, and it slows my heart rate back down. I did not think it would help, but it does!! I'm so happy!

How Cryo-1 Helps Anxiety
Anxiety Hijacks the Body
For many people, anxiety doesn’t start with thoughts. It starts in the body.
Your heart races. Your breathing tightens. A wave of fear builds. And the harder you try to control it mentally, the more exhausted you feel.
This fear of spiraling - and the constant effort to manage it - is often more draining than the anxiety itself.
What’s Happening Inside Your Body
Anxiety activates your sympathetic nervous system - your body’s fight-or-flight response.
- Heart rate increases
- Breathing becomes shallow
- A sense of urgency or danger takes over
Until the nervous system receives a signal that it’s safe, anxiety can continue to build.
Activate the Parasympathetic Response
Vagus nerve cooling has been clinically studied for decades.
By holding Cryo-1 against the side of the neck, users can help signal the body to exit fight-or-flight, slow heart rate and breathing and allow anxiety to ease more naturally.
This isn’t distraction. It’s a physiological signal.
Peer Reviewed Science
Targeted cooling has been studied for its effects on vagal pathways and autonomic balance.
