It wasn't always so, but nowadays you see many people wearing some kind of fitness watch, often a full-blown smartwatch by Apple, Samsung or Google and several others. But I'm going to confine myself to fitness-orientated watches designed mainly to track the things that sportspersons need to know in order to assess their performance capability. Watches typified by the wide range offered by Garmin, and in particular my own watch, a Garmin Vivoactive 5 that I bought in May 2024.
Mine is a middle-of-the road fitness watch, a step up from a Fitbit, but not one of Garmin's high-end watches for athletes. Even so, it can record a lot of information. Not just steps taken; I originally set it up to monitor my sleep, the naps I might take, my heart rate, my heart rate variability, my breathing, how much stress I cope with, and my current energy level. I could have set up even more, but I am no fitness fanatic, and just wanted to see a few more things than the Fitbit Versa 3 I used to own could tell me. And in any event I wanted to tell the time on a device that was shaped like a proper traditional watch, with a round face. Although my Vivoactive 5 does shout 'fitness watch' it isn't overlarge, nor cluttered with rotating bezels, big buttons to press, and other practical-but-ugly features like that. I can wear it anywhere, with any kind of outfit.
Well, to begin with I was fascinated with the measurements it took, which I synched to the Garmin Connect app on my phone every morning. (To save battery-power, I've never had Bluetooth on all the time. That way, I can go at least a week between watch recharges) The app processed the metrics and presented the results usefully, and with comment. Sometimes it congratulated me. Mostly it didn't. I put the negativity down to Garmin supposing that I was an aspiring and serious contender in the fitness stakes, and that I would appreciate the truth, with no molly-coddling.
As I simply wanted to be ordinarily fit, I felt I could snap my fingers at Garmin's tut-tutting. And for a long while I did just that. But I knew Garmin was right in not giving me good sleep scores: I sometimes went to bed at ridiculously late times, and really didn't get enough good-quality sleep. That was unsustainable in the long run, yet I did nothing to correct it, and therefore kept on getting a wagging finger from Garmin.
One thing that irritated and also puzzled me was the stress that my watch recorded. I didn't feel stressed in the ordinary way, and certainly had nothing significant to burden me - no family responsibilities or financial pressures, for instance. But my watch said that I was often maxed out with it - when driving in heavy traffic, or when seeing my friends, and every time I felt some emotion or excitement.
Well, perhaps I have exciting or stimulating friends! But it was strange that after an evening with them, fully half my sleeping hours might be 'stressful', impacting very badly on my sleep score. Why? I'd got to sleep easily enough.
Was simply being with people stressful in itself, at least for me? Indeed, did it reveal that I was autistic? Thankfully, my average stress level for the whole day would be low. But those spikes were odd.
And then something else began to worry me. In the last months since last July my Heart Rate Variability fell away, and got very low. I gathered it was an indication of how easy my heart would find it to speed up in an emergency, so that if necessary I could run away or leap aside, and escape sudden danger. In other words, my watch was suggesting that my heart would have a hard time beating faster on demand: that I wouldn't be able to snap into a sprint to outpace a charging bull, or a slavering mad dog, or a man with a knife. Not that I'd had constant problems with these things in the past.
I felt increasingly uncomfortable - and concerned - about these low HRV measurements. So when I had occasion very recently to visit the doctor, I brought my poor HRV to her attention. The watch was measuring microsecond differences between successive heartbeats, but how should this be interpreted, and should I really be concerned? She wasn't clear on that. A specialist sports doctor would know, but it wasn't part of a GP's training.
However, she did recommend an ECG and blood tests to see why my heart rate was on the low side - a different issue that both my watch and my home blood-pressure measuring device had revealed. I hadn't been bothered about the low heart rate, but she was.
And so first thing in January I will turn up at the surgery and get those things seen to by the practice nurses. I have two appointments set up on successive days. I feel well, and I'll be surprised if there is any underlying issue; but I'm pleased that these checks are happening quite soon.
Meanwhile, a better sleeping regime has been in force with good results. I have set up various alarms on my Garmin watch to get me to bed at a sensible time, and these mild prompts have done the trick. I'm already sleeping longer and deeper. And - slowly - my HRV has begun to improve. So perhaps there is a strong link between good-quality sleep and heart health.
A few days ago I took stock. Had pondering daily, sometimes hourly, on my health and fitness metrics been good for me? Clearly not. There was no doubt. I had become addicted to looking at the health metrics on my watch, as badly as those who can't resist glancing at their social media feeds. And because I was constantly checking, I saw things that were simply of the moment, and not typical of my general state. The stress metric, for example. Surely I was getting too much information, too often, and it was grinding me down. I needed to stand back and consider the general picture. The trends over a period, not passing ups and downs.
So I've resolved to have only a couple of metrics visible: how many steps taken (which gives me a daily target, an incentive to keep moving, and a great feeling of achievement if I take 10,000 steps or more), and - for now - my heart rate (which at this very moment, sitting down at the end of the day, and typing this post, is 57 beats per minute). I hide the rest. I can drill down to see them, but I find it easy to resist. And I now sync watch and phone app only once every three days. That way I can still see my metrics, but the immediacy has gone, and I can study them coolly. I see both the drag-downs and the bounce-backs. And if three days between syncs isn't enough, I'll make it a week.
I like my watch. I want it to be my useful friend, telling me the time, nudging me with gentle alarms, and helping me stay on my feet sufficiently to maintain a basic level of fitness. I don't want it to be a tyrant, nagging me, and telling me that on some things I am failing.
I think I should regard my watch as a broad indicator of fitness, rather than a substitute for hospital-grade devices. You do hear stories about how a fitness watch warned someone of an impending heart attack. I dare say they are true. But I can now see how, if not used with discrimination, these watches can bear down heavily on one's general wellbeing, and create real stress. Which in turn will bring about various bad effects. I hope I've now done enough to avoid that trap.
