Part 6 The Danger with Default Skepticism
August 7, 2020WHOOP vs. Oura vs. Biostrap – User Friendliness and Value
August 16, 2020Comparing Sleep Monitoring Devices: Oura, Biostrap, and WHOOP
Sleep is critical. I’ll repeat and expand: not only is sleep absolutely critical, but proper sleep hygiene is also key for preserving and protecting our health. Sleep and the ramifications of improper sleep is something I am very interested in. Last year, I wrote a four-part series on sleep, which totals over 10,000 words:
I’m interested in sleep for my own health and conducted several projects evaluating my own sleep, including these three:
- Fasting: I measured the effects fasting had on my sleep, including during fasts and 15-month retrospective analysis.
- Alcohol: I experimented with sleep quality after low, moderate, high, and extreme doses of alcohol and the consumption of hydrogen-rich water, using a two-participant, double-blind placebo-controlled crossover design, which included myself and my wife.
- Sleep Quality Comparison: This was a 30-day analysis of before and after using the OOLER (advanced sleep system involving temperature regulation) in a two-participant, open-label, controlled design.
I have also advocated exploring the effects of hydrogen water on sleep and acute sleep deprivation with various research teams. The results of our most recent clinical trial suggested that our hydrogen tablets were as effective as 100mg of caffeine at raising attention after 24 hours of sleep deprivation in young, healthy participants. You can read our article here.
Additionally, a research team from a major U.S. institution is conducting extensive preclinical work on the effects of hydrogen water on sleep quality and recovery from acute stressors that impact sleep in mice. In addition, two other research teams are planning to incorporate our hydrogen tablets in clinical research assessing sleep quality. Sleep quality could very well emerge as a top research interest for hydrogen water in the coming years, based on the early data.
Comparing Sleep Monitoring Devices
Due to my interest in sleep and hydrogen water, it only seemed logical to evaluate the three most commonly utilized “wearables” within the “biohacking” community, with a strong emphasis on sleep measurements.
Three main points of the devices include the following::
- None of the devices are as accurate as polysomnography. All of them utilize similar technologies but the algorithms differ.
- Although none of the devices are accurate enough to compare sleep quality across a population, they are all likely accurate enough to observe changes within an individual. For instance, the devices will decipher your sleep patterns and determine with reasonable accuracy whether your sleep is improving or getting worse.
- Oura and WHOOP have third-party research published comparing their data recording to polysomnography, while Biostrap does not:
As one publication notes, although the Biostrap does not appear to have any of its data validated, the company at least features a “research opportunities” section on their website, suggesting they are open to the concept:
Come back next week for my analysis on the winning devices vs. the full power sleep tracker tech found in Serta-Simmons BeautyRest, which is validated to 90% accuracy against polysomnography in 90% of people.
Drawbacks and Advantages of Oura, Biostrap, and WHOOP
Drawbacks
Oura always penalizes me for going to bed too late. I have always been a “night owl,” but it has not adapted to my sleep habits.
Biostrap does not differentiate between deep and REM sleep, combining the two totals.
Also, Biostrap does not measure respiratory ratio.
WHOOP does not give an actual resting HR, only providing a graph that you can use to estimate it.
Advantages
Oura is the only device that measures nocturnal body temperature; however, unfortunately, it does not graph its changes throughout the night.
WHOOP has adapted to my sleep schedule and recommends a time to go to bed and optimal sleep duration using my typical schedule as a frame of reference; however, sometimes their advice is quite stupid and nonsensical. Every night, the device gives me a “minimum viable sleep” suggestion that has me going to bed later than I have any night within the time I started wearing it, usually, 1:30 am -2 am for minimum viable sleep. Once, it was even several hours later than the latest I typically get to sleep. I tend to fall asleep between 11:30 pm -12:30 am every night, but one night it suggested I go to bed at 2:25 am and get to bed by at least 4:10 am!
BioStrap has no observed positives compared to the other two devices.
Observational Deficiencies of Oura, Biostrap, and WHOOP
Biostrap is the only device that failed to register my sleep for an entire night within the 30-day window. The strap was fully charged.
WHOOP does not record both segments of my sleep when they are significantly “fractured.”
Oura does not have this issue with my data, but my wife has had the following two significant issues with OURA:
- She tends to fall asleep on the couch most days as I unwind either working/writing or watching TV. She then moves to the bed, and on some nights, she comes back to the couch. OURA seems to register one or two of her sleep segments as “rest,” and only the largest chunk as “sleep.” As such, her sleep numbers are significantly impaired on most days. Fortunately, they are consistently impaired, as this is a daily occurrence, not occurring at random and low frequency.
- OURA does not measure deep sleep for my wife. On many days, the device registers less than 30 minutes of deep sleep for her. However, I can attest that she sleeps very deeply. Typically, I need to both shake her, while raising my voice to a yell, to wake her up from the couch to come to bed. On the other hand, I tend to wake up numerous times throughout the night, even from noises such as our cat jumping from the bed to the carpet and the almost imperceptible “thud” which accompanies it. Both Oura and WHOOP record me as sleeping “deeply” a large percentage of the night, but Oura rarely records my wife entering deep sleep.
Readiness & Sleep Score
Observationally and subjectively, for me, I found Oura to have the most accurate “sleep scores,” although I do believe they trend too low as I am punished for being a “night owl.” WHOOP scored my sleep as “very good” on nights I know I was compromised, such as when I was very intoxicated or undertaking long water fast.
For readiness, Oura seems to be the most accurate for me. In contrast, WHOOP scores my readiness far too low on many days, and Biostrap lacks consistency.
Sleep Score Data
*Sleep is scored for the night AFTER the activity of the day, i.e., day 1, then night 1.
Calories refer to ACTIVE calories burned on top of resting caloric burn.
HRV refers to heart rate variability (a measure of variation in time between each heartbeat).
RHR refers to resting heart rate.
*RHR does not show in WHOOP. Bpms are estimates based on the graph here.
RR refers to inter-beat intervals. Biostrap does not score this, thus it is omitted in the table below.
REM DEEP: Combines Deep and REM sleep
Body temp refers to deviations from baseline body temperature.
