We looked at sleep and activity data for several years, looking at both Sleeptracker® and MotionX® activity information. The data clearly shows similar patterns from year to year. Thanksgiving and the Holidays, in general, change our sleep and activity levels significantly. Here is an article form the New York Time that discusses some of this impact:
We know that heart rate throughout the night is a sign-post of health and recovery. So we asked, “is it true that the more we sleep, the lower the average heart rate is throughout the night?”
The data shows that this is not necessarily the case, and that includes our weekly work schedules and weekend opportunity to sleep in.
For example, on average, we spend the most wake-time on Fridays, and as the graph shows, our average heart rates are higher on Friday nights. During the corresponding Saturday mornings, we tend to sleep in and our sleep durations end up longer, yet our heart rates throughout the night are higher.
One possible explanation is an increase in REM sleep when the heart rate is generally elevated. Of course, “lifestyle” (alcohol and larger / later meals) also contribute to elevated heart rates measured on Friday and Saturday nights.
For the last four years, Sleeptracker AI data has recorded significant disruption in sleep patterns during the fall when we wind the clock back, losing an hour of daylight. In comparison, the state of Arizona does not change its time for Daylight Saving Time. As a result, their data does not show a disruption.
The following link points to a recent discussion on “CBS This Morning” regarding the potential impacts of fall sleep disruption. youtu.be/Bk8zqWKeLy0
Daylight Saving Time disrupts our sleep. Twice a year, every year. Sleep Disruption! Arizona and Hawaii get it right! The data shows that the switch back and forth to and from Summertime affects us all, night owls as much as morning larks. Both are affected in the same way, on average about three weeks of sleep pattern disruption per year.
We all live in a sleep-deprived society, regardless of age. In the graphic below, we studied sleep deficits from Fullpower’s PSG-level Sleeptracker AI platform. Of course, we should all sleep longer, but the reality of modern life is that we only have so much of a “sleep budget” given the constraints of family, work, social media, etc. Therefore, a complementary focus is on the quality of sleep: Improving sleep quality for better sleep is important. For that purpose, bedding, mattress quality, respiratory environment, and temperature control are very important as some of us sleep hot (mostly males) and some of us want to be warmer. All of the above are potentially big contributors to sleep quality, or what we know as restful sleep.
Of note here, women typically average less of a sleep deficit than males.
This plot assumes a target sleep time of 8.5 hours for those under 22 and 8 hours for those above 22. In line with recommendations from the National Sleep Foundation: //www.sleepfoundation.org/articles/how-much-sleep-do-we-really-need. It’s “conservative” for those under 22 meaning you could increase it and show even more of a deficit for that age group (just shifts the y-axis labels).

At Fullpower Labs, we were thinking about last week’s Seattle earthquake and doing some geographical distribution analysis. That earthquake hit right in the middle of our night. So many of those Sleeptracker users around Seattle got affected. Here is a graphical representation using the Sleeptracker AI-powered predictive analytics of how that sleep disruption developed.
At Fullpower Labs, we analyzed our accurate multi-year data-set that comprises 250+ million nights of sleep. We found some interesting seasonal patterns. This infographic shows seasonal changes in heart rate. The Fullpower Sleeptracker platform captures continuous heart rate throughout the night completely non-invasively. Each individual fluctuation in the graph is a weekly max and min, the max being in general weekends (bedtime and wake-time discipline are more lax on weekends) and weekdays with a more disciplined schedule and less “distractions”.
This is what we can observe:
- Seasonal changes occur with lower heart rates in the summer and higher in the winter. This same pattern was also observed in this independent study in Japan. Our AI-powered analytics discovered this independently and then we found the very interesting Japan paper.
- There’s a consistent weekly cycle throughout the year with lower heart rates during the week and higher on the weekends (affected by time to bed, diet, and alcohol).
- We see a big spike for New Year’s eve (time to bed, diet and alcohol).
- There’s a significant dip after New Year’s, perhaps due to New Year’s resolutions (better diet, decreased alcohol, more disciplined sleep schedule), but eventually, it fizzles.
- We see another spike after the Super Bowl.
This week at Fullpower Labs (www.fullpower.com), we’ve been thinking about how much we sleep and don’t sleep each day of the week on average; so we did some distribution analysis. Most of our Sleeptracker (www.sleeptracker.com) sleepers have regulated work schedules which bind them to a fixed weekday schedule. However, there are still several differences. And of course, many of us tend to replenish our “sleep budget” on weekends.
The following image displays the statistically meaningful weekday patterns that we represent using the Sleeptracker AI-powered predictive analytics system.
For three consecutive years, data has shown that when the US “falls back,” we are likely to see disrupted sleep for two weeks in the Spring. The disruption is a little less in the fall.
The Sleeptracker platform will be analyzing and “machine learning” anonymized big sleep data over the next few weeks with tens of thousands of sleepers every night.
Let the data speak!
