A claim my co-authors and I make in an upcoming paper on sleep onset and insomnia is that perturbant emotion causes insomnolence. This is not to say that perturbance is the sole cause of insomnolence. In fact, our theory proposes five postulates about the evolutionary design of the human sleep onset control system. One of the postulates pertains to perturbance. Read more ›

Over the last several months, I’ve been too busy doing research and development —including on sleep onset and insomnia —, writing papers, and managing a new product launch, to contribute much to this blog. But the work we are doing will have major benefits for mySleepButton. I wish I could spill the beans, but first things must come first. Meanwhile, I would like to draw your attention to an excellent new research-based book on sleep by Dr. Matthew Walker called Why We Sleep.

As promised, mySleepButton version 1.4.12 for iOS  has been released with support for Siri Shortcuts. You can now define shortcuts to tell Siri to “put me to sleep”, and it will start playing mySleepButton. This is handy if you’re sleeping alone and want to control mySleepButton without even looking at your iPhone or iPad. Read more ›

The next release of mySleepButton for iOS, version 1.4.12, will contain support for Siri Shortcuts. You will be able to tell your iPhone or iPad “put me to sleep” and it will launch or resume mySleepButton’s play. You will also be able to pause or stop mySleepButton. Siri Shortcuts are of course configurable

If you’d like to beta test the new version of the app, just send us an email using the app. Caveats: we first need to roll out a new build, and have Apple approve it (which can take some time). Also, we can’t guarantee that we will accept all beta testers (due to time and resource constraints).

Last year Quartz published an article by Lila MacLellan on mySleepButton: An app that helps you sleep, built on cognitive science. On the 10th of this month, Quartz published You should be sleeping more than eight hours a night. Here’s why . I highly recommend this article.

Quartz publishes useful, high caliber articles. It is owned by the venerable Atlantic Media. It is one of my favorite websites.

We’re very pleased to announce the first public results of a longstanding project, which is to bring mySleepButton to the Japanese speaking world. Read more ›

Media and researchers alike often focus on the dark side of sleep: that (and why) we don’t get enough sleep, and that sleep deprivation has significant adverse impacts on biological and mental health, well-being, productivity and error rates.  Amongst the many other things sleep researchers study, they also study behaviors and interventions that promote sleep. It is difficult to measure the impact of this research on a societal scale. However a study was published online in January (and available in print this month), whose authors argued that sleep duration in the US may be improving, perhaps as a result of the dissemination of sleep research.

There are several big ideas behind mySleepButton’s current and upcoming cognitive shuffle packs (as well as DIY versions). I’ve written some papers about these ideas before, and am currently co-authoring a new paper with Célyne H. Bastien on the subject. The theory we are developing is called the “somnolent information-processing theory“. Read more ›

In mySleepButton 1.4.9, introduced last week, we resolved the mySleepButton crackling issue, that we had been tracking on our iOS support page, and that we had mentioned in previous blog posts.

What an excellent app this is. I have come to rely on it, for sure. After years of using music, which has mixed success, this shuffle business does exactly what it says on the tin. Read more ›
