Jawbone UP Fitbit Flex

Can wearable technology really change your life?

Simon JonesCan wearable technology really change your life, or is it just a passing fad? In this article Simon Jones from wearabletechwatch.net explains how the last few weeks have been a revelation and how a smart wristband is to thank for providing an early warning of a potentially major health issues.

It all started when I bought a smart wristband last year – first a Jawbone UP and then a Fitbit Flex. As a desk jockey, I was fascinated by the idea of tracking my movement, or rather lack thereof, although I very quickly tired of the idea of total immersion into the quantifiable self: This is hard work and involves tracking everything. But what turned out to be the life changer for me was actually a feature that I’d first ignored: Sleep tracking. During the first days of having a smart wristband, I’d taken it off to charge up overnight as I was skeptical as to what a glorified pedometer could tell me about my sleep patterns.

But of course, I had to at least give it a chance, so after a few nights of “just trying it” I found that the tracker data had a surprise in store: although I was technically asleep, or at least in an unconscious state, this sleep was very restless. What started the alarm bells ringing was that this was not only for a few minutes here and there, but as a repeated pattern through the night – almost each and every night. Typically, my smart wristband reported, I’d be asleep for less than an hour before long periods of nocturnal movement. Sometimes these could go on for hours on end, before I’d finally settle back into deep sleep.

My sleep stats ultimately made me take action. The first step was buying a new mattress, which helped double my longest uninterrupted periods of sleep, to around three hours. Then my wife started using a tracker, too, and her phenomenal ability to pack in deep sleep (even managing to avoid being disturbed by my chainsaw-like snoring) was even recognised by Jawbone’s UP as being in the “top 5% of sleepers”, while her Fitbit Flex reports often show a continuous deep blue line.

The kicker was that comparing our sleep stats led me to a major “a ha” moment: For years I’d simply known that I needed more sleep than my wife, but we’d just taken this at face value. Data from my Fitbit Flex tracker showed that I did indeed need more sleep, because I simply wasn’t getting enough deep sleep during a normal night. I’d also started waking up with headaches and feeling perma-tired, to the point where some days I’d need to battle through with a combination of concentration, will power and caffeine. Before consulting a medic, I tried a number of solutions – avoiding late-night alcohol, no coffee after 4pm, even turning down the brightness of computer displays at night-time – but nothing seemed to work. So the only thing to do was to take my data to a doctor.

It felt silly telling my doctor that despite sometimes getting nine hours a night in bed, I wasn’t getting enough sleep. Fitbit data helped: even in a high-tech country like Germany, I’ve discovered that almost all the medics have never seen or heard of a smart wristband – although my doctor showed enormous interest in my Fitbit’s sleep stats. After some basic tests (lung capacity, cholesterol levels, blood pressure), I was sent home with a DIY sleep tracking kit: a clunky beige box with a set of sensors that I was to adhere to various parts of my body before going to sleep. It’s easier said than done to fall asleep when you’re wired up with EKG pads, a fingertip sensor that tracks pulse and blood oxygen levels, and a nasal air pressure tracker. Following much grumbling about fitting it all, I finally drifted off to sleep and let the box track my progress.

After returning the box to the doc the following morning, the results not only confirmed that I had a problem, but also just how many sources of data the thing had tapped into. There was a glorious, full-length MP3 soundtrack of my nocturnal hours, a full breakdown of my pulse, and a correlation between dips in my blood oxygen and periods when I stopped breathing: for up to a minute at a time. Despite having the appearance of an old BBC Acorn computer, the device was pretty impressive, since it also tracked how much time I spent in different sleeping positions, body temperature and all movements on three different axis.

The doctor immediately referred me to a sleep clinic, for further investigation into a condition called sleep apnea, since my hourly average number of “apnea” per hour was well above the normal threshold. This is a medical situation that occurs when the muscles at the back of your throat relax, sag and obstruct your airway, during sleep. The muscles themselves are damaged over time by the vibrations caused by snoring. If there’s an airway obstruction, then your body starts convulsing while the blood oxygen level drops (which also leads to morning headaches). After a while, and this can be two minutes or even longer, an oxygen-starved body instinctively starts waking up, you move, take a deep breath, and oxygen levels go up. Then it happens again. In my case, after a particular one-minute apnea, I took just three breaths before my breathing stopped again … and this pattern went on for more than an hour.

In short, you’re sleeping (not driving) with the brakes on. If it’s not addressed, then sleep apnea can lead to a hugely increased risk of heart disease, and can explain cholesterol build-ups and higher blood pressure: all because you’re not getting enough decent sleep. If you’re loathed to buy a smart wristband which tracks sleep, there are also smartphone apps, although I’d recommend putting the phone on flight mode before tucking it under your pillow.

    Very few people know how a smart watch could alctaluy benefit them. 1. Because the marketing on these types of devices has been non-existent. 2. Cellphones helped kill wrist watches. I think if some of these tech companies were smart they would continue development and provide more features. This type of device could create a whole new sub-industry just like Bluetooth headsets just kind of popped into the scene and have now become commonplace. No body knew what they did or what purpose they would have. We first started seeing people walking and talking to themselves and then driving and talking to themselves until we finally all realized that they were alctaluy on the phone. I’m sure you all had that bizarre experience. Well I think smart watches will be slower to adopt until we get real innovation and great emotional marketing behind it.I currently have widgets disabled because I noticed is slows the watch down and just have Txt msg, Missed calls, Call handler, Calendar, and Gtalk notify enabled. Just the txt messaging feature and call handling alone is worth it for me.Sometimes the phone loses connection with the watch but most times if the phone is near I get a nice connection for then entire day. I really wish Sony would continue developing the software for this but I kind of doubt it. Sony has a habit of putting out technology and not really following through if sales aren’t up in my opinion. I do see a lot of room for growth and I would like to customize the interface more but other then that it’s a great first step in what will become the next big thing that’s if Google glass doesn’t steel its thunder.Here are a few examples on how I use/enjoy my Sony Smartwatch:1.When driving I like getting notifications and not having to check my phone while diving. I can choose to respond at a light or wait till I get to my destination.2.If I’m at a noisy bar I really feel special reading a txt I get. People notice and it’s a great conversation starter.3.You can know who is calling you before you pull your phone out of your tight skinny jeans. For the ladies they will know who is calling them before they can dig it out of their bag.
