I love sleep. It’s a bit of a running joke amongst my friends that they pretty much know not to contact me after 10pm on a weeknight as it’s likely I’ll be tucked up in bed trying to catch some zzz’s. And while I could probably sleep for Scotland if it were an Olympic sport the quality of sleep that we get is actually way more important than the quantity (although getting enough sleep is still vital!) So when I was invited to test run the S+ by RedMed – the world’s first non-contact sleep tracking system – I jumped at the chance. Just how good a night’s sleep was I getting?
Before I start my review, it is important to say that the ResMed S+ is not a medical device and it is not approved for treating medical conditions. It is a lifestyle device, designed to help you track your sleep.
The bedside device uses a highly calibrated respiratory and bio-motion sensor to measure and analyse sleep stages. It records movements caused by the expansion and relaxation of the chest with breathing in and out, and overall body movements such as positional changes, arm twitches and shrugs. Each morning, the S+ app delivers sleep scores and sleep charts to a connected phone or tablet, and the S+ Sleep Mentor uses a software algorithm based on over two million nights of sleep data to deliver personalised feedback and suggestions to help users improve their sleep.
After downloading the app, entering a few personal details and answering a few questions about my sleeping patterns and lifestyle I was ready to go. The device works over Bluetooth and all you have to do to get it started is hit the sleep button. The app also has a couple of handy built-in features to help you drift off peacefully including Mind Clear where you can leave yourself written or voice memos for the following day so that you don’t forget and Relax to Sleep which plays soothing audio that synchronizes with your breathing before automatically fading out.
In the morning you’re presented with your sleep report including an overall sleep score out of 100. You can see at a glance when you were in each stage of sleep and for how long. Contributing factors to this score include environmental factors such as light and room temperature and every day you’ll be given a little recommendation for something you can do to improve your sleep for the following night. Mine usually consisted of saying I should do some exercise but up until the last week or two that really hasn’t been possible.
I’ve been using the S+ for a couple of months now and as with anything it has its pros and cons which I’ll share with you below so you can make up your own mind:
- It’s a non contact device so you don’t have to wear anything on your wrist overnight to keep track
- It’s super accurate – you can see exactly how much time you spend in each stage of sleep
- The Mind Clear and Relax to sleep features are incredibly useful for busy minds
- You’re provided clear, actionable steps each day towards getting a better nights sleep
- You need to remember to actually switch it on. This is a problem for me as I often go to just lie down for a sec and end up falling asleep!
- Price – at £129.95 it’s an investment and not something everyone can afford
- Self fulfilling prophecy; if the app tells you you’ve had a bad night sleep you might just believe it even if you’re feeling well rested
