Review – The ResMed S+ Sleep Tracker

ResMed Sleep Tracker Review

A  good night’s sleep is increasingly regarded not only as the best but the most crucial medicine for our health.  Without it not only are we operating below par in the short term, but long term we are susceptible to a range of life threatening illnesses.

Our health is our wealth and in a society where there is no longer a clear demarcation between work and leisure, never has the value of sleep been more pertinent. In the words of Thomas Dekker “Sleep is the golden chain that ties health and bodies together.”  The shorter your sleep, the shorter your life.

Sleep is fashionable. Talk about sleep routines, sleep hygiene and sleep apps is commonplace and only last week the Nobel Peace Prize for Medicine was awarded to a trio of scientists for their discoveries relating to the Circadian Rhythm, the human sleep/wake cycle that dictates our need for sleep.  We are quite literally a nation obsessed with sleep.  I confess to being one of those people.  So does that make me a sleep bore?  Personally I would like to think of myself as being “bang on trend”, although I am sure my teenagers would almost certainly disagree.

So with my confession to sleep obsession firmly on the table, you won’t be surprised to hear that when asked to review the ResMed S+ Sleep Tracker I jumped at the chance.

What Is The ResMed S+?

Quite simply it is the world’s first non-contact sleep tracker.   If you are still wearing a fitness band on your wrist to monitor your sleep (which I was) then I am sorry to be the bearer of bad of news, but you are behind the times.  Things have moved on – considerably!

Widely regarded as the technology dunce in our family, I was firmly pushed to one side by my geek husband and youngest teenager when the ResMed S+ arrived.  Never have they been so keen to help and as each stage was completed my husband could be heard muttering “This is such a clever bit of kit.”  

Despite being overpowered on this occasion, I can assure you setting it up is straightforward even for someone like me. You simply sync it with your smartphone or tablet, set up an account, answer a few questions about yourself and your lifestyle (honestly of course as my husband kept reminding me) and you are ready to go.

To look at, the ResMed S+ is quite simply a shiny white box encased in brushed steel, a bit new-age in appearance but nonetheless sleek and stylish, which is exactly what you want from something that is going to be on your bedside, or at least I do!

Of course it is not as basic as all that.  Inside the white box are all the brains and sensors of the machine which are going to help advise you on getting a good night’s sleep.  A LED glows red in the middle of the box when the S+ is on but not connected and green when your phone is in the vicinity. The white box tilts in the frame so you can angle it towards you regardless of the height and position of your bedside and this is important to check each night because if it is not angled correctly it quite simply won’t record, as I found out to my detriment on a couple of occasions.

Sleep Tracking

When it is time to turn in for the night, the ResMed S+ monitors the light, noise and temperature in your room and recommends the ideal levels for the perfect sleep environment.  Then you hit the sleep button on the app and answer a few questions on your specific state before going to sleep, namely how stressed you were that day, how many caffeinated and alcoholic drinks you consumed and how much exercise you did.  After that you can choose to clear your mind and relax ready for sleep.

The mind clear feature I found particularly useful. Like most mothers, I go to bed with a multitude of things going around in my brain from that day and in anticipation of the next.  Mind Clear enables you to either record a voice text or enter a text message to get the thoughts out of your head before going to sleep.  It certainly worked for me and is better than waking in the middle of the night and reaching for a notepad and a pen.

After this you either set the SmartAlarm and/or turn on a calming sound to send you to sleep.  To be honest with this feature I think it is down to personal taste.  My husband rather liked being lulled to sleep by the sound of crashing waves whereas I found it irritating, but then again I am exactly the same if I have a facial, I cannot stand the background tubular bells style music that is intended to help you relax, so I think this probably says more about me than the feature.

The flip side of this, however, is the Smart Alarm which I LOVED.  This gives you a 15 minute window during which to wake and get up, so if your alarm is set for 7am the Smart Alarm starts easing you into the morning around 6.45am with gentle sounds which start off quietly and gradually increase to the point when you need to get up.  As a non-morning person this for me was a much better way to be woken up than the harsh, uncivilised ringing of an alarm bell, whereas my husband who loves mornings and jumps out of bed at the first sound of the alarm found this pointless.  We agreed to differ on these features. But then again it was my sleep it was monitoring not his, he just happened to be nearby!

The Sleep Data

In order for your data to be collected you do have to have your phone plugged in.  Now as a firm believer of “no phones in the bedroom”  and insisting my teens leave theirs downstairs when they go to bed, this seemed counter-intuitive but on the plus side once you have confirmed you are going to sleep, the screen does not emit the bright blue light that stops your brain producing the melatonin you need to nod off.  As this is one of the biggest reasons screens are discouraged in the sleep environment, this was my rationale when challenged by my teens.

So here is the really interesting part and the bit that I think sets the ResMed S+ apart from all the other sleep trackers I have used and that is the score and analysis of your sleep.

Forget the basics of how many hours you have slept, the ResMed S+ breaks your sleep down into four components, Deep, Light, REM and Wake, the latter including the time it took you to fall asleep and any disruptions during the night.   Each has an ideal score for your age and gender and your personal sleep score is measured against each of these.

Sleep restores us both mentally and physically and each morning you can see what you achieved overall for your mind (REM) and body (Deep) within the ideal scenario.  Both of these stages are vital to our well-being but it is the balance of time spent in both of these phases that will make the difference between the general feeling we all get on waking of having slept well or not.

The first night I used the tracker was the weekend prior to my eldest teen leaving for university. Probably not a good time, but then again I wanted to see the bad bits of my sleep, not just the good.  Not surprisingly perhaps with a house full of teens invading the house after a farewell party for my son, my sleep score was rubbish and disturbances plentiful on the first night.  Ditto the next night, prior to his departure. The mind clear feature came into its own on this occasion as I woke frequently agonising over what we might have forgotten to pack, so when I woke sluggish and fretful the next morning with a deadline for departure and a husband telling me to hurry up, I could at least refer to my middle of the night notes!

Unfortunately my sleep did not improve much over the next few days after dropping him off and my worst recorded sleep score was 53 but this was probably a good place to start.  My life and that of my family was changing big time so what better place to start with improving my sleep than at the bottom?

The ideal sleep score is 100.  My highest score to date has been 98, but the journey in between has been so interesting and it is not over yet.

As well as your score the S+ Mentor feature gives you advice aimed at improving your sleep going forward, obviously with the view that you make adjustments and your score goes up.  After one particularly poor reading this was its personalised suggestion.

People of your age typically get 6h 17m of total sleep time, 1h 26m of REM, 1h 6m of deep sleep and 3h 44m of light sleep.Your REM sleep last night was 0h 34m. REM sleep is the time when the majority of your dreams occur.  Try the Relax to Sleep feature which senses your breathing rate and matches the speed of the sound to it. Slow the sound by slowing your breathing and then follow the sound as it leads you into a relaxed state and finally into sleep.

I find the analysis of how long I spend in each stage of sleep fascinating and it is easy to see how sleep becomes addictive.  I love sleep but what the ResMed S+ has made me realise is that over the summer I have become lax with my normal sleep routine which quite simply is having a detrimental impact upon the quality of my sleep.

I have been using the ResMed S+ now for three weeks and interestingly the nights I have slept the deepest are when my husband is away on business.  I have no way of knowing for sure but when my sleep history shows disturbances I generally assume it is due to his snoring.  I am not quite sure where that leaves me or us for that matter but I have made progress and I have loved the tips proffered along the way – although clearly there were none suggesting I sleep alone!

The Value of Sleep 

I have written previously about my battle with menopausal insomnia and my efforts to find a solution to those specific issues, but that midlife crisis aside, a good night’s sleep is a prerequisite for life and particularly as we age. Adults aged 45 years or older who sleep less than six hours a night are 200% more likely to have a heart attack or stroke in their lifetime than those clocking up seven or eight as recommended by the World Health Organisation.

Matthew Walker, neuroscience professor at Berkeley, California believes we are in the midst of a “catastrophic sleep-loss epidemic”.  He claims that in the UK alone, the NHS spends an eye-watering £50 million a year on prescriptions for sleeping tablets but that sleep loss costs the UK economy over £30bn a year in lost revenue.   You don’t have to be a genius to realise that there is something wrong there somewhere.  In his book Why We Sleep, Walker argues that the real need is to get to the root cause of why we are not sleeping and remedy it.

Achieving the correct amount of quality sleep is a discipline  With the help of the ResMed S+ I have started to redress the balance.  Of course it is not a perfect science.  Living gets in the way sometimes and as a result there have been peaks and troughs in my sleep journey but like with everything else in life it is work in progress.  The quest for perfect quality sleep continues and whether that will come with a 100 sleep score I am yet to find out.  In the meantime, as Homer said “There is a time for many words and there is also a time for sleep.”


Disclosure: I received the ResMed S+ in exchange for an honest review.  All thoughts and opinions are my own and unbiased.

      A good mattress is definitely a pre-requisite. We invested in a vi spring a couple of years ago and haven’t looked back. Would highly recommend this gadget though too. It makes me consider my sleeping habits (including the bad ones) a lot more and the advice is very good.

    I seem to be one of the few people I know with the ability to sleep at an Olympic level. One of my tips (as such) is stay up late. I know it sounds odd, but trying to sleep before midnight will have me tossing and turning for hours; going later means I drop straight off to sleep. I’m sometimes curious about the actual patterns within my sleep as, like Laurie above, I can wake, talk about the dog making a noise, or something happening outside, and not remember a thing next day, but I almost think the knowledge of being monitored would disturb me! #tweensteensbeyond

      Ah Mary you see I fall in the camp of those that believe an hour before midnight is worth more than an hour after and on a normal night freak out if I find the bewitching hour upon me and I am still awake. But clearly this works for you and I am envious of your ability to fall asleep so easily. Thanks for your comment as always. #TweensTeensBeyond

    I have to be honest here (gulp), I think technology has gone mad. Knowing what was going on/not going on during the night would just give me something else to stress about, and consequently stop me going to sleep in the first place lol! It sometimes feels that every bit of our life is being monitored and commented on by technology. Clearly I’m a dinosaur, but I reckon I can live with that 🙂 #TwwensTeensBeyond

      Ha ha. I know what you mean. Since I started having problems sleeping I have now become obsessed with sleeping well and trying to improve the way I sleep. The ResMed S+ has taken me to a different level of obsessiveness, almost self-indulgent really but I love it. This is really a device for those like me and it sounds like you maybe lucky enough to be getting good quality sleep already. If that changes you will know where to turn for help. #TweensTeensBeyond

    i too would find it fascinating to see how long i sleep for and how deeply at what stages, but i really need is something that would help me sleep in the first place #tweensteensbeyond

      Sleep is that ever challenging issue and particularly as we get older. Mine is definitely improving but I still have good and bad days and I am still holding out for that perfect 100 score – if that is even attainable. #TweensTeensBeyond

    Fancy! So high tech. I surrender right now–I couldn’t manage the technology. I can barely manage my iPhone, LOL! Thanks for sharing your experience.

      I can assure you it is easy Katy but I understand what you mean completely. Thanks for reading. #TweensTeensBeyond

    Wow that is very clever. It’s almost science fiction! I love the facility to leave a voice message. I am always waking up with something playing on my mind and lie awake worrying that I will have forgotten it by the morning. It’s hard to jot it down in the dark! I have always truly valued my sleep, even when I was younger. Now that I am in midlife I seem to need it even more! I blame the fact that I got so little of it when the kids were younger! #TweensTeensBeyond

      I love sleep and am a complete horror without it and it does make so much difference to everything that happens the next day, our mood, our actions, our thoughts etc You can see why there is so much hype around sleep. It is totally fascinating – sorry that is my sleep bore coming out in me again! #TweensTeensBeyond

    I too have periods of menopausal insomnia so I would be really interested in this, Jo. At the moment I think my hormones have kicked back in as I’m sleeping much better and not gardening at 3am! However I would be interested in analysing the data of the quality of my sleep as I feel tired a lot of the time and I’ve often wondered if I’m still only sleeping very lightly as everything seems to wake me! I think I may invest in one, honestly. Thank you so much for this review. I would be interested in how you get on in another 3 months or so. #tweensteensbeyond

      It has become an obsession with me Sophie, but it is interesting the split between light and deep sleep and how long they recommend you are in each stage and how you can maybe alter that with changes to your routine. I love the sleep tips as much as the bar charts but have not always been good about following the advice offered! As I say I am still learning and will report back later on my progress, have my HRT review coming up too! Oh what it is to be a menopausal woman! #TweensTeensBeyond

    How interesting. I too would be more interested in the stages of sleep and how good they actually are. Apparently, according to my partner, I die when I fall asleep! I never have a job going to sleep and I often get up in the night with no knowledge of it. I wake most mornings feeling like I have slept well though. I would be most interested to take a look at the different stages of that sleep.

      It sounds like you don’t have any sleep issues Laurie at all! Funny that you get up in the night and have no knowledge of it! Are you sleep walking? As with all these gadgets the data analysis can become addictive. I am still chasing the perfect 100 score! Thanks for hosting.

    Wow this looks a really interesting bit of kit. I have an iWatch and I’m gutted it needs charging each night so can’t track sleep. The iPhone apps always seem a bit cumbersome too. This looks the biz!
    Thanks for sharing with #coolmumclub
    PS I so need to use that no phones in bedroom rule.

      I would highly recommend it. My fitbit was always running out of charge and was actually uncomfortable in bed, this is a much better solution for sure. Ha ha re the no phone rule! It is a toughie but Dr Martin Lee has some very good insights into the detrimental impact on our health. If you haven’t read his post before do take a read. #coolmumclub
