Figure 1 Self-explanatory: NY parties the most, and surprise, Las Vegas the least. The explanation is simple: That’s because Sleeptracker users in Vegas actually work in Vegas and are not visiting to party. In our little piece of paradise in Santa Cruz, SurfCity, we tend to go to bed early to catch the surf in the morning before work.
Figure 2 is about heart rate and the effects of alcohol on sleep. After studying millions of nights of sleep we noticed that alcohol pumps up heart rates significantly. We can see this here when on NYE, people tend to drink more. And guess what: The younger crowd drinks much more and heart rate gets significantly affected.
