Oura ring review – What we learned about the sleep tracking ring

A slew of wearable units from rings to wrist-worn trackers hit the market in 2019, claiming to assist individuals study extra about their sleep.

They’re serving a giant market, with analysis displaying that greater than 60 million Americans suffer from some form of sleep problem. The so-called “exhaustion economy” is flourishing globally, as customers and even their employers are beginning to pay for consulting companies, particular mattresses, and extra.

I’ve by no means been recognized with a sleep situation, however I’ve lengthy questioned whether or not there are steps I may take to optimize my shuteye. I’ll usually have at the very least one night time monthly the place I’m up till the wee hours of the morning staring anxiously at my clock. And there are actually days the place I hit the wall at four p.m., and really feel like curling up in a nook.

So on the recommendation of a pal, I met with the group at Oura, which makes a sleep-tracking machine, of their San Francisco places of work to see if I achieve any new insights. Oura, which payments itself on its web site because the “most accurate sleep and activity tracker,” sells its ring for $299 and up, which places it on par with the Apple Watch.

Oura, like different sleep trackers, is not an official different to a doctor-ordered sleep examine within the lab, which includes monitoring an individual’s mind waves, oxygen stage, coronary heart fee and different components. But it does have a look at customers’ exercise at night time utilizing its built-in accelerometer and gyroscope, and it incorporates sensors monitoring different related metrics like coronary heart fee, respiratory fee and physique temperature.

Another cause I selected it: Oura, not like its rivals Fitbit and Apple Watch, is tremendous centered on sleep so it’s designed to have fewer leisure options and due to this fact an extended battery life.

While getting fitted for the machine, which is available in a wide range of sizes, Oura’s CEO Harpreet Singh really helpful that I spend at the very least two weeks monitoring my sleep so I may begin to see patters and developments within the information. I took his recommendation, and began in late October of this yr by sliding the silver ring on my index finger. (I’ll be aware that some girls with very slim fingers would possibly discover that even the smallest-sized ring is just too massive.)

The ring I wore, which is a second-generation design, is way thinner than the earlier one, which might have engulfed my finger. I appreciated the ring higher than wrist-worn units as a result of it is so unobtrusive — I did not actually discover it after some time. Stylistically, although, it appears a bit of bizarre if you happen to’re already carrying a marriage ring — even if you happen to put it on the alternative hand.

The first and second technology of Oura rings


Design apart, here is what I realized from my sleep-tracking experiment:

Sleep cycles

Oura reveals the three main sleep levels: Light sleep, deep sleep and REM sleep (for speedy eye motion). There’s additionally some element about sleep latency, which means how lengthy it takes for an individual to go from totally awake to asleep, in addition to restlessness and whole hours of sleep.

These sleep phases are vital for various causes. Deep sleep is thought to be a very restorative time, whereas REM sleep is believed to stimulate the areas of the mind which can be important to studying and making recollections.

Sleep cycles are usually about 90 minutes and an individual will want 4 of 5 of these to get a extremely good night time’s sleep. It’s frequent to see extra REM sleep within the last hours of sleep, whereas deep sleep tends to occur earlier.

The Oura information indicated that I usually go to sleep earlier than midnight, expertise extra REM sleep beginning round 3am, and drift right into a deep sleep-heavy cycle round 1 or 2am. I averaged out at about 7 hours of sleep per night time.

I felt pretty glad in regards to the quantity of sleep I used to be getting, because it fell inside most suggestions of seven to 9 hours. But most mornings, once I checked my information within the Oura app, I did discover that both my proportion of each REM and Deep Sleep had been within the pink, and in a number of circumstances, each.

Oura breaks down your sleep into classes.

To discover out if I ought to fear, I turned to Dr. Seema Khosla, who sees sufferers on the North Dakota Center for Sleep.

After reviewing a number of nights of my sleep information, Dr. Khosla mentioned she wasn’t apprehensive. She famous that a lot of her sufferers, who’ve sleep circumstances like sleep apnea, may have ranges of REM sleep within the low single digits, whereas most of mine hovered round 15 to 25 %, in addition to lots of interrupted sleep. So in her view, the app may have given a bit extra leniency to sleepers like me to keep away from any pointless nervousness.

She additionally questioned whether or not I’d have scored greater if I had gone to mattress earlier, however she could not essentially suggest that. As she factors out, everybody’s circadian rhythm is totally different. And for me, getting up a bit of earlier is not essentially going to steer me to be extra productive the following day. Unlike morning individuals, I get bursts of power within the afternoon and thru the night.

She additionally famous that the accuracy with sleep trackers normally is considerably suspect. Oura may be higher than some apps and units, in that it tracks much more than most, but it surely’s nonetheless not as thorough as a sleep examine. So whereas the developments would possibly usually be proper, she suggested that I take the information with a grain of salt.

Anxiety about sleep monitoring

There was additionally one main caveat I ought to share: Once I began utilizing the Oura, I observed that I took off the tracker on nights the place I knew I would not sleep nicely.

It’s a bit embarrassing to confess, however I began to get caught up in attaining an ideal sleep. And it seems I’m not alone. There’s a condition called othosomnia, which includes some individuals with sleep trackers getting lower-quality sleep as a result of they’re anxious about attaining a greater rating.

On nights the place I tossed and turned and did not put on my Oura, I used to be extra efficiently capable of persuade myself that I received extra sleep than I truly did. And that helped me get by way of the day.

In equity to Oura, they by no means inform you that you just received unhealthy or poor-quality sleep, and as an alternative current a so-called “readiness” rating.

But seeing the information made it very laborious for me to inform myself that I should have gotten extra sleep than I truly had.

And that is one cause why sleep consultants like Khosla will usually advise sufferers to put in writing down how they’re actually feeling within the morning earlier than they seek the advice of their sleep monitoring app.

Patterns and insights

Once I had all this info, I pulled up my calendar to have a look at occasions that I used to be touring, organized drinks with buddies or guzzling down extra espresso than normal.

Some potential patterns emerged:

  • Booze is not nice. I noticed a connection between the nights that I had a number of glasses of wine, and the nights the place I received fewer hours of deep sleep.
  • My cats appear to wake me up a good quantity. I’m fairly a stressed sleeper, and it does not assist once they’re shifting round at night time.
  • The first night time of journey is especially icky: Apparently I do not sleep all that nicely in resorts.
  • Exercise helps, however not too late within the night. It seems that train most likely bolsters my sleep high quality, but when I work out too late, I observed that it’s going to take me longer to go to sleep.
  • I ought to most likely sleep a bit of extra and earlier (that, I knew).
  • By far the good factor Oura: I observed a slight bump in my physique temperature one morning, and some days later got here down with a chilly. I did not get an alert that I may be getting sick, but it surely did give me a heads as much as take it straightforward for a number of days. (And I’m not alone).

But after realizing all of this, it wasn’t completely clear what I ought to do about it. It’s laborious to keep away from journey altogether, and I do take pleasure in a glass of wine or a cocktail sometimes. Giving up espresso may be one other noble purpose, however I genuinely take pleasure in a morning cup and I doubt I’d stick with it for lengthy.

Changing conduct

And that brings us to conduct change. Here’s the place all of it will get difficult.

Dr. Khosla usually felt I received about sufficient sleep. I’d usually make up for a poor night time or two of shuteye through the week by taking it straightforward and prioritizing my relaxation on the weekend.

That mentioned, Khosla urged methods I may enhance my sleep hygiene. She will usually suggest her sufferers go to mattress simply 15 minutes earlier, and report again to her in the event that they noticed a distinction. And if that’s the case, transfer their bedtime incrementally earlier till they’ve hit the candy spot.

Another advice I received from Dr. Khosla, however not the Oura app: Put away telephones and laptops earlier. She urged discovering a strategy to wind down that does not contain looking the Internet or being reminded of tomorrow’s duties, like {a magazine} or an audio e book.

In my case, she famous that I may attempt holding the cats out of the bed room for a number of nights to see if it helped.

But that vital suggestions loop between a affected person or client and a (ideally human) well being coach was lacking from the Oura expertise. If you are not completely self-motivated, it will likely be laborious to place your insights into motion.

All in all, I received extra tangible info and concepts out of A 15-minute dialog with a physician than two weeks of laborious information. I walked away considering that sleep monitoring must evolve to fulfill the wants of a inhabitants that is not deriving worth from info alone. Some individuals would possibly spot developments on their very own, and sport out learn how to make enhancements. But others will want extra insights and extra teaching, primarily based their distinctive life and on a regular basis habits.

“Ultimately I think we’re still figuring out what the purpose will be of all this new technology,” mentioned Dr. Khosla. “For that reason, lot of my patients will show up with this data, wondering what an earth they’re supposed to do with it.”
