Like many people, Christel de Maeyer felt that her sleep could be better. Presenting at our 2013 conference in Europe, Christel shares what she learned from collecting over three years of sleep data.
What did Christel do?
Christel tracked her sleep for 2 years with various devices. She tested the effects of different variables on her sleep quality, including consumption of alcohol, keeping a consistent wake time and changing her mattress.
How did she do it?
She used the Zeo to track sleep for two years, before switching over to a BodyMedia device. While making changes she monitored how her sleep data changed, as well as how she felt.
What did she learn?
Before self-tracking, Christel felt that she woke up frequently during the night, and the Zeo confirmed this. On average she woke up around 8 to 9 times. She suspected the mattress could be part of the problem. After considerable research, she replaced her mattress (to one that had a foam top), successfully reducing her wake-ups to 4 or 5.
Christel discovered that her sleep patterns looked significantly different after just two glasses of alcohol. Her REM diminishes to nearly 0% (though deep sleep seems unaffected).
Christel also found that total sleep time was less important for how she felt the next day than the combination of REM and deep sleep. Even if she only sleeps for six hours, as long as she gets at least 2 hours of combined REM/deep sleep, she feels good.
In addition to these findings and others she explores in the video above, Christel has taken her lessons and now helps others with sleeping issues. You can find more at her website.
Jan-Geert Munneke has had an issue with snoring for quite a while. He started off his self-tracking journey by tracking his snoring with the Snore Lab app. Having this data led him to think about how he could understand what was going on while he was sleeping. So, he decided to incorporate more sensors to better track his sleep. In this talk, from our 2013 Quantified Self Europe Conference, Jan-Geert describes what he found from combining data from different devices and how it’s inspired him to think about how he could track other aspects of his sleep.
Our show&tell talks usually give you insight into new and different self-tracking projects from a first person perspective. What we rarely hear about is how a self-tracking practice affects those around you, your family and friends. In this wonderful Ignite talk from our 2013 Global Conference Bill Schuller explains how his tracking has impacted his kids and what he’s learned from their experiences.
If you’re a loyal, or even infrequent user of the Zeo sleep tracking device then you’ve probably heard the sad news that the company has shut down. This opens up a lot of questions about what is means to make consumer devices in this day and age, but rather than focus on those issues we’ld like to talk a bit about data.
Zeo has been unfortunately a little quiet on the communication front and there are quite a few users out there who are wondering about what will happen to all those restless nights and sound sleeps that were captured by their device. This has been compounded by the fact that the Zeo website went down for a short time (it is up as of this writing) closing off access to user accounts and the data therein. Lucky for you there have been quite a few enterprising and enthusiastic individuals who have taken the time to create or highlight ways to capture and store your Zeo data.
Use The Zeo Website
You can’t fault Zeo with making it hard to access your own data. As long as their website is up you can easily download your sleep data from by logging into your user account at mysleep.myzeo.com. After logging into your account you will see a link on the right hand side labeled “Export Data.” Click that link and you’ll be able to download a CSV file containing all your sleep data. They’ve even provided a description of the data and formats that you can download here.
Eric Blue’s FreeMyZeo Data Exporter
QS Los Angeles Meetup Organizer and hacker extraordinaire whipped up a simple data export tool using the Zeo API. The great thing about Eric’s is that even if the myZeo web portal goes down this tool should continue to work.
Download Data Directly From the Device
If you’re using a Zeo bedside device then you can continue to use it and download the data directly from the memory card without relying on uploading it to the Zeo website. In order to do this you’ll have to read the documentation and use the Data Decoder Library. These files are hard to find as they’ve been removed from the Zeo developer website, but you can access them from our Forum thanks to our friend Dan Dascalesu. Zeo also created a viewer using this library that you can use via this Sourceforge page.
If you’ve found another way to download Zeo data please let us know. You can also participate in the great forum discussion that inspired this post.
Ari Berwaldt wanted to better understand how his sleep affected his mental performance. In this great talk Ari explains his insights from tracking his cognitive skills using Quantified Mind and some surprising results about the lack of correlation between his Zeo data and his mental performance. Make sure to keep watching as Ari also explains some very interesting data and conclusions from blood glucose and ketone tracking during fasting. Filmed at the QS Silicon Valley meetup group.
The entertaining and curious Joe Betts-Lacroix shares his investigation to decide which device he will use to track sleep. He includes how he uses each device, his opinions and how one device makes him feel that his sleep matters! (Filmed at the Quantified Self Silicon Valley meetup at Stanford’s Calming Technologies lab.)
Emily Singer, a journalist with MIT’s Technology Review, has an extensive series of articles and interviews on “The Measured Life“. She was at the Quantified Self Conference a month ago, seems to have talked with everyone, and has since been writing up a storm.
There are also video interviews. Kyle Machulis describes his efforts to hack tracking devices so everyone can access their own data. David Marvit talks about Fujitsu’s Sprout project and the importance of obtaining biometrics in real-world conditions. And Rajiv Mehta talks about the potential for personal science to make a significant impact on healthcare and medical science, and demos Tonic.
And there are posts on social networking and games in self-tracking technologies, on astronauts measuring sleep, a physician’s perspective, the new Health Graph effort, and a wristwatch that continuously monitors blood pressure.
There’s a great new post over at the Zeo blog by an experienced polyphasic sleeper – instead of sleeping in one 8 hour chunk, he breaks it up into three segments throughout the day. In his post he shows how he used Zeo to help optimize sleep quality and create a polyphasic schedule that feels better for him than the more common monophasic sleep.
Zeo co-founder Ben Rubin spoke at the last Bay Area QS Show&Tell at Stanford University. Click on the video below to hear his thoughts about measuring sleep and the future of Zeo.

Do you meditate, run, or sleep? Ramesh Rao does all three. Not only that, but this grounded Professor of Electrical and Computer Engineering at UCSD tracks his heart rate and brain waves while he’s doing these activities.
We heard a bit about quantified meditation from Robin Barooah at a recent San Francisco QS meetup. Professor Rao takes it to another level. I had the pleasure of meeting him and hearing his story this past week. He graciously agreed to let us post his findings.
In his words:
Electrical signals that trigger the beating of the heart are not quite periodic and the larger the variation the healthier the heart! A transplanted heart shows very little heart variation. Alienated. Since 1965, when the first findings on HRV were reported, numerous studies have documented the correlation between lowered HRV measures and increased fatigue, stress, exhaustion both physical and mental.
A Task Force of The European Society of Cardiology and The North American Society of Pacing and Electrophysiology concluded in 1996 that:
Heart rate variability has considerable potential to assess the role of autonomic nervous system fluctuations in normal healthy individuals and in patients with various cardiovascular and non cardiovascular disorders.
A lay reading of the scientific literature suggests that HRV entrains many physiological, psychological and emotional responses. As a result HRV is a rich, if garbled, source of invaluable information. For close to 21 months now, I have been gathering comprehensive HRV data during my early morning aerobic work and nightly yoga practice. I also have an assortment of interesting additional recordings: a four day long trace, a recording of the bliss of sedation during a colonoscopy procedure and meditation sessions.
