There's lots of interesting tidbits for anyone interested in sleep tracking. So to be fair, if you split the study up into averages for men and women, the average woman is only 10 minutes short of the recommended 7+ hours a night whereas men are way down on 6 hours 26 minutes. Women also apparently get 10 more minutes of REM sleep a night than men.
Age is another big factor, not only in the duration and quality of sleep but also what time you go to bed. So Gen Z teens (classed as aged 13 -22) get on average six hours and 57 minutes, with 17% deep sleep, compared to six hours 33 minutes, and 13% deep sleep, for baby boomers (age 52 and above).
People in the youngest group go to bed on average at 12.08am; 11.45pm for millennials (23- 40 here); 11.25pm for Gen X and 11.17pm for baby boomers.
Also interesting is the 55 minutes a night people spend awake or restless, though one of Fitbit's sleep experts says even a 30 minute stretch of being awake is fairly common.
Sleep Stages is Fitbit's new way of tackling sleep tracking - the feature is live on the latest trackers including the Fitbit Charge 2, Blaze and Alta HR. It tracks motion and heart rate variability and uses this data to provide personalised insights based in science.
Our US editor Hugh recently trialled the new Sleep Stages software and found that the recommendations are a "solid foundation" for making sleep tracking useful. In June this year, a study by the Sleep Research Society found that Fitbit trackers have a 69% accuracy compared to polysomnography equipment in a lab.
Fitbit is recommending between seven and nine hours sleep a night - you can see how your own sleep stats compare to the averages in the Fitbit app.
