The latest in sleep tech features everything from cooling your brain to training it.
Bedtime innovations from CES 2020
Dozens of products - some preparing for crowdfunding campaigns and others awaiting approval from the U.S. Food and Drug Administration - debuted on the CES floor for the first time.
U.S. company Ebb Therapeutics introduced its new wearable device that's designed to cool a user's frontal cortex by circulating a water-alcohol solution that ranges from 15 degrees Celsius (59 degrees Fahrenheit) to 18 degrees Celsius (64 degrees Fahrenheit) inside what looks like a sleep mask atop the user's forehead.
Eric Nofzinger, the company's founder and chief medical officer, said the device is for individuals whose minds race and may have trouble falling asleep due to their active brain activity, particularly in the frontal cortex.
The fluid solution is kept in a cooling box and pumped through a hose to the headband.
Users can set the temperature and decide how long to wear it, taking it off before bed or leaving it on through the night.
The device was first available under a prescription model, but it's now available as a consumer product for $499.
Meanwhile, plenty of products targeted those who can already fall asleep easily.
French electronics company Withings introduced its newest smartwatch with CEO Mathieu Letombe describing the Core ScanWatch as their most advanced product yet.
The watch, a 2020 Innovation Award Honoree at CES, can detect atrial fibrillation and sleep apnea.
According to the National Heart, Lung, and Blood Institute, sleep apnea "can occur when the upper airway becomes blocked repeatedly during sleep, reducing or completely stopping airflow." If untreated, NHLBI says the disorder can lead to serious complications, including heart attack, glaucoma and more.
Letombe called it a game-changer and said only one night with the watch was needed in order to detect sleep apnea.
All results from the watch are tracked in an app and can be shared with the user's doctor.
The watch, which can also do an electrocardiogram reading and identify one's blood oxygen level, is pending approval by the FDA.
Its four models range in price from $249 to $299.
Another French company is also trying to get into the U.S. sleep tech market.
URGOtech unveiled its new wearable device URGOnight designed to train your brain to better ignore changes in sound, temperature or light that may occur at night and interrupt your sleep.
The headband device and its corresponding app are targeting sensory motor waves that help improve sleep protection.
By using the device and app - 20 minutes a day up to three times a week - CEO Guirec Le Lous says you can train your brain to improve those sensory motor waves through games on the app.
Some games include killing jellyfish, blowing bubbles, moving icebergs, growing leaves on a tree, all of which Le Lous describes as positive reinforcement.
He said the products is due to go on the market in June, costing about $500.
