January 3 is the Festival of Sleep Day. I have some bad news for those of us who like sleep apps, though. Studies have found that few apps that claim to help you monitor your sleep are tested scientifically. And the ones that have show weak correlation to standard sleep tests.

Instead of a sleep app, try mediation podcasts/services like 10 Percent Happier, Calm, Headspace and Insight Timer to help you disconnect from the world and get better sleep.
