How does CoolDrift® work?

Our innovative, proprietary, science-based solution addresses the root cause of sleeplessness by reducing activity in the frontal cortex of the brain. Imaging research and clinical studies conducted by internationally recognized sleep specialist, Eric Nofzinger, MD, demonstrated that precise, constant cooling of the forehead calms the Racing Mind, making it easier to fall asleep naturally and enter more deep, restorative sleep through the night.

Can’t I just use an ice pack?

CoolDrift is the only product proven to cool the forehead to a precise temperature range, reducing racing thoughts and promoting the natural onset of sleep. An ice pack is not effective in that it’s both too cold and cannot maintain its cool consistently through the night.

Has CoolDrift been clinically tested?

Three independent clinical studies were conducted in seven prestigious sleep centers across the U.S. on more than 340 individuals, over 6,500 research nights, to demonstrate the safety and effectiveness of the precise cooling. In the primary randomized controlled trial, participants used CoolDrift technology 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.

Getting Started

Will I experience results the first time I use CoolDrift?

Many of our users have reported success on the very first night. Others need some more time to adjust. For best results, we recommend that you spend at least 14 nights with it to get settled in with it and give it time to improve your sleep.

What temperature setting should I start with?

All temperature settings are validated to be effective and should be chosen for your comfort. For CoolDrift Versa, we recommend starting on setting #3 then adjusting for comfort (setting 1 is the least cold and setting 5 is the coldest). For CoolDrift Luxe, we recommend starting with temperature setting P7 (P1 is the coolest setting and P10 is the warmest). It can take up to 10 minutes for CoolDrift Luxe to reach the set temperature.

General Questions

Can I control the temperature?

Yes, CoolDrift’s temperature range can be customized for individual preference. CoolDrift Versa has 5 temperature setting options and CoolDrift Luxe has 10.

What is the best temperature setting? Is colder better?

All settings will help to promote the natural onset of sleep, so choose a temperature that is most comfortable for you.

Can I change sleeping positions during the night? Can I sleep on my stomach?

The CoolDrift products can accommodate any sleeping position. However, if you are a frequent stomach sleeper, CoolDrift Luxe may be better suited for that due to its slim, wrap-around design.


How can I return CoolDrift?
