Hold Cryo-1 against the side of your neck. Most people report a calming effect within 2 to 4 minutes, with no medication.
“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.”

“When I feel a panic attack coming on, I cool my neck and it slows my heart rate back down.”
For many people anxiety doesn't start with a thought. Your heart races, your breathing tightens, and a wave of fear builds. The harder you try to think your way out, the more drained you feel.
Neck cooling helps signal your body to leave fight-or-flight and slow the heart rate. Palm cooling reduces the heat buildup that often comes with anxiety. This isn't distraction — it's a physical signal.

“Cooling my palms seems to interrupt awful wave before it becomes a full panic. I still use breathing exercises too.”
PANIC RESPONSE
“Something as simple as my daily schedule getting messed up used to trigger instant heart racing. Now I reach for cryo-1 and it helps a lot.”
HEAT-TRIGGERED ANXIETY
“I got overstimulated and hot in the crowd. Sitting in the quiet car with cold palms helped my breathing slow before the ride home.”
CROWDS + OVERSTIMULATION
“Carrying this does not prevent it panic attacks, but I feel prepared instead of helpless.”

Targeted cooling has been studied for its effect on vagal pathways and heart rate. Here is what the research found.
A randomized trial with 61 healthy participants applied cold to the lateral neck in 16-second intervals. It significantly raised heart rate variability and lowered heart rate compared to baseline.
In 11 adults, 90 minutes of localized neck cooling dropped neck skin temperature about 9°C and slowed heart rate significantly during the cooling period.
In adolescent cyclists, neck cooling reduced perceived heat, lowered ear temperature, decreased heart rate during recovery and reduced stress markers in the blood.
