The Shortest Night of Sleep in the US in 2017! We looked at the data, millions of nights of sleep using the Sleeptracker Predictive Open Analytics and here it is. At first, we were incredulous because we thought that Valentine's day or Halloween night would be shorter. Not so.  Superbowl night still has us all on the average sleeping less than any other night in 2017. It's not a matter of opinions, it's what the data shows!
