Why it works

Palm cooling and warming helps regulate your body's thermostat.

The problem

A hot flash starts fast

Hormone changes make your body's temperature control more sensitive, sometimes as early as in your 30s and 40s. Heat surges, your heart races, and chills can follow right after. It interrupts sleep, focus and everyday life.

THE PHYSIOLOGY

Your body reacts like it's overheating

  • Your blood vessels open to release heat
  • Your heart rate increases
  • Sweating and flushing begin
What cooling does

The palms are built to move heat

Your palms hold special blood vessels that readily transfer heat. Cooling them cools the blood which then moves to your core, noticeably cooling your entire body.

  • Cool during a heat surge
  • Warm during the chill that follows
  • Help your nervous system settle

“I keep it in my bag. Ten minutes of sitting there sweating versus two minutes and it's over — that's a big difference to me.”

“Night sweats used to mean I was awake for an hour. Now it's a couple of minutes and I'm back asleep.”

Peer reviewed science

What the research shows

Research shows that core temperature regulation can help relieve peri-menopausal symptoms.

Menopause narrows the thermal comfort zone

Postmenopausal women have a much narrower thermoneutral zone. Very small changes in core temperature can set off a flash, so shedding heat faster matters more than it used to.

Lower core temperature, fewer and milder flashes

A 2015 study supported the link between reduced core temperature and fewer or milder flashes. Cryo-1 applies the same principle through palm cooling.

performance note

Designed for controlled conditions—not extreme heat

Cryo-1 relies on the surrounding air to cool effectively. For best performance, use it indoors or in moderate ambient conditions. Above 80°F, cooling performance and duration can decline significantly, and maximum performance should not be expected.
