THE DREEM HEADBAND FOR INSOMNIA
Before I tried the Eight Sleep Cover, I had decided I wanted the Dreem headband in November 2020. Unfortunately, the device had been placed on a backorder status. After a few months of promising more stock, the company finally admitted it had a new CEO and was no longer available to consumers. Instead, the French company was only going to make the device available to doctors and sleep labs. However, representatives continue to provide some support online and it seems the headbands still receive firmware updates. As of this writing, the app is no longer available on the app store and the last update was December 4, 2020. Still battling sleep-maintenance insomnia where I will wake up several times a night and unable to fall back to sleep, I was determined to see what it could do. Mainly because it claims to assist in recovery with the help of CBT-i coaching. Cognitive Behavioral Therapy for Insomnia is a proven method to help people overcome all forms of insomnia, with a high success rate of 70-80% among patients with sleep disorders. I have also decided to finally make an appointment with a sleep medicine doctor for a sleep study.
Just like the Eight Sleep reviews that I had found, the majority of Dreem reviews are done by people who do not have sleep issues. Why these people feel their opinions matter is beyond rationale. And nowhere was I able to find any information regarding how the CBT-i sleep training worked - even the Dreem site is vague. With the device no longer available to the general public, I began bidding on used headbands on eBay. There are two iterations of the Dreem: the original Dreem 1 and the updated Dreem 2. The key differences are essentially this: the Dreem 2 is more comfortable, is adjustable, is more accurate, and has better audio (they both have an audio jack, though); the sensors on the Dreem 2 are spring-loaded for a lighter and more even touch; both feature the same sensors, although Dreem 2 adds a sonometer to detect sleep apnea (both count breathing cycles per minute); Dreem 2 headbands sold outside of Europe do not stimulate deep sleep* via pink noise, while the Dreem 1 does so worldwide.
* this seems to have been due to the FDA approval being too difficult (it is registered with the FDA, not approved), but I don't understand how they snuck pink noise into the first version. The pink noise is not unlockable via the app - from what I can gather, it is the hardware and the US devices are not hackable.
I finally procured one within my desired budget: a Dreem 1 v2 for $550 early May 2021. Although I would prefer the improved Dreem 2, I had a direct communication with an employee last year who stated the Dreem 1 was still a good option. Plus, prices skyrocketed in 2021, especially for overseas Dreem 2 models that were capable of producing pink noise - this was something I wanted to try due to my belief that I was not getting adequate deep sleep.
The App, The Manual, and Customer Support
My used Dreem 1 has a charging issue where it does not fully charge and on certain days it is worse, charging to only 91%. I had seen posts by employees stating they will continue to provide help to legacy owners. So, I inquired through the Dreem site mid-May 2021 and within a few hours, Jonathan had replied telling me he would evaluate the headband. I gave him my login ID so he could verify which headband to remotely take a look at. The next day, he sent me a screenshot of my charging history from the previous few days and assured me that my Dreem was fine. He believes it is reaching full and then discharging a little - I don't think this is the issue (I'm thinking natural battery degradation and/or it is out of calibration), but I was impressed at how responsive he was. So, customer service is still there for private users and is very good.
Turning the device on can be tricky because there is no audio verification - start up is usually a minor nuisance because of this. If you're unsure, the app conveniently lets you test that the sensors are reading your brainwaves. After that, you click the Sleep button and the app tells you that you can leave the app and go to sleep (you should also hear the device verbalize this). During the first couple of nights, this is where you hope you did everything right - though if you don't see the one red LED sensor on the inside of the band lit up, that's a good indicator it is not recording. Once the recording starts, the Dreem will eventually turn off the Bluetooth and Wi-Fi so that there is minimal power usage and no signal transmissions. When you wake up, you hold the button down to turn the device completely off (a crescendo verifies this) and then plug it into the charger. The headband then pairs with your phone and the data uploads automatically so that you can review it. During the first seven nights, sleeping options are limited to only setting an alarm - you may not hear it if you rely on white noise and aren't using headphones or ear plugs. Once the first data collection week is over, all options and programs will become available.
Unfortunately, the headband can sometimes misinterpret some people as being asleep when they are actually awake. I've found this to be especially true in the mornings when I wake up too early and try to return to sleep. Alpha waves occur while resting with our eyes closed and then these waves will disappear during sleep. Dreem claims that certain people do not produce many alpha waves, so if they are lying very still while awake, the device may interpret this as being asleep. Of course, this also means that the Dreem's time stamp for when I first fall alseep is usually earlier than I think it should be. From my experience, it will usually mark this error as light sleep. So, if you lie awake for hours in the middle night, it may still say you had an efficient night of sleep. Fortunately, this does not seem to affect the CBT-i program.
* my shift schedule is 24hrs on and 48hrs off, but I am now fortunate enough to be at a fire station that isn't up all night, every friggin night ...so I have a good chance at a normal sleep schedule. I think the app classifies shift work as overnights, where you are defying your body's Circadian Rhythm several times a week. Running calls all night is partly what got me here - and let me tell you, those calls were rarely serious and/or emergent, which made it extremely frustrating to not sleep. Unfortunately, a CBT-i program will not work well for someone that can't maintain a consistent and normal sleep window. I'm sorry, but I don't know what advice to give you except to recommend that you switch to day shifts.
Cove seems to be similar to the previous headband in that it is also used during the day ...and was developed over the span of four years. But instead of training your brain through what looks like game-style exercises, the Cove attempts to increase alpha waves that stimulate relaxation and calmness, much like meditation. This headband doesn't read your brain waves, it stimulates them with skin vibrations while you are free to do other tasks and can be used during the day and/or before bed. The Cove is worn at least once a day for twenty minutes and promises dramatic improvement to all sleep metrics after a month of use, with boasts of some subjects noticing a difference the first night. The company claims that the Cove helps 86% of users and, on average, increases nightly sleep time by 65mins.
Each of these devices costs $500 and offer payment plans. It would be interesting to get a baseline with the Dreem and then use one to see if a difference is noted with the Dreem's EEG data.
