Calm Your Mind for Better Sleep

<span>Calm Your Mind for Better Sleep</span>

Our precise cooling is scientifically validated to calm the overactive part of the mind to induce sleep

Harness the power of cooling to fall asleep faster.

Wind Down for Sleep

Use CoolDrift 20-30 minutes before bedtime as part of your evening routine, maybe while you’re relaxing on the couch. You can choose to remove it before getting into bed, or leave it on all night.

Ultra Portable Sleep Solution

Cooling pads in the headband deliver continuous cooling wherever you need it. The sleek, portable design makes it ideal to pack for travel or to wind down in any room of the house. The rechargeable battery means that it doesn't have to be plugged in during use.

*Travel Case Not Included*

Versatile Use

Use Versa 20-30 minutes before bed then remove it to sleep, or choose to leave it on all night for gentle comfort. Keep Versa on your nightstand for quick relief from nighttime racing thoughts or hot flashes.

Personalized intelligent algorithm

The CoolDrift Versa algorithm adjusts itself to work with your body's natural temperature fluctuations so that a precise temperature is maintained. With three cooling pads distributed across the forehead, they can compensate for one another if one shifts while you're wearing it.

My Doctor Recommended. It Just Works. Period.

I suffer from two types of insomnia, and I have sleep apnea. Each night, I take pills to fall asleep and stay asleep. Still, I awake at 3 a.m. This device had significantly improved my quality of sleep, including increased deep sleep. It was recommended by my board-certified sleep and lung doctor. So glad he made the recommendation.

Easy to wear and it works!

I have used the ebb Cool Drift Versa every night for 2 weeks, and I’ve had fantastic results. I recommend this product to anyone who has sleepless nights or often struggles to fall asleep fast due to racing thoughts. I’ve noticed that I am able to fall asleep quickly and without waking multiple times throughout the night!

Frequently Asked Questions

What temperature setting should I start at? dark-arrow-down

When you turn on CoolDrift Versa for the first time, the temperature setting will automatically start at 3, which is the midpoint temperature. We recommend starting at 3 and adjusting for comfort. 1 is the warmest temperature setting and 5 is the coldest temperature setting. All temperature settings are effective in helping you with your sleep, so choose the one that is most comfortable for you.

Has CoolDrift been clinically tested? dark-arrow-down

Multiple clinical studies were conducted involving 340 subjects and more than 6,500 nights, including a pivotal study that was published in Journal SLEEP, May 2018, to demonstrate the safety and effectiveness of our precise cooling. In the primary randomized controlled trial, participants used CoolDrift for multiple nights in a sleep lab and were assessed by Polysomnographic recordings analyzed by sleep clinicians. The innovation’s precise cooling produced improvements in the ability for participants to fall asleep and enter deeper, more restorative sleep faster. Participants experienced no significant side effects.

How long will the battery in the PowerWand last? dark-arrow-down

A fully charged battery is designed to last for a whole night of sleep (8 hours or more). The 4 green LEDs on the side of the PowerWand indicate the proportion of battery life remaining.
