It’s not the primary time Apple has hung a USP on well being and life-style performance – sequence four launched us to fall detection and ECG (electrocardiogram) measurement, and coronary heart charge measurement was accessible from sequence 1.
Others have adopted swimsuit, and the wearables market now appears firmly centered on a broader vary of monitoring, in addition to health.
Learn on to search out out about a few of the key health-tracking options on provide from Apple and wearables manufacturers, and what you could possibly anticipate to see sooner or later.

Apple Watch sequence 6 introduces SpO2
The Sequence 6 doesn’t signify an infinite step ahead from the Sequence 5 with regards to options (we’ll let you realize about efficiency once we’ve absolutely examined it), however the brand new blood oxygen sensor has definitely grabbed consideration.
Different claimed updates for the Sequence 6 embody a display that may get a lot brighter in daylight and higher battery life – so that you received’t be obliged to cost it every day anymore.
Apple has additionally simply launched watchOS7, accessible on the Sequence 5, four and three in addition to the Sequence 6.

Blood oxygen (SpO2) monitoring with a smartwatch
Blood oxygen monitoring, aka SpO2 monitoring, aka pulse oximetry testing, measures the oxygen saturation of your blood.
The brand new Apple Watch Sequence 6 (pictured above) can take on-demand readings of your blood oxygen and background readings in the course of the day and evening.
It really works by shining pink and inexperienced LEDs and infrared gentle onto your wrist, and measures the quantity of sunshine mirrored again. An algorithm then estimates the color of your blood – blood with extra oxygen is brilliant pink; blood with much less oxygen is darker.
Apple isn’t the primary model to include pulse oximetry in some format into wearable tech. We examined a variety of watches and trackers with pulse oximetry options not too long ago. Some impressed us, giving us readings in the identical ballpark as our medical pulse oximeter, whereas others struggled – notably on darker pores and skin.
Pulse oximeters have been within the information a good bit this yr, because it’s been prompt they may assist spot early indicators of coronavirus. Nonetheless, it’s unlikely to be a standalone answer. Londonwide LMCs, a consultant committee of NHS GPs within the capital, says that: ‘Pulse oximetry generally is a helpful help to scientific decision-making however it’s not an alternative to a scientific evaluation, nor enough for analysis by itself.’
We’ll be placing the Apple Watch Sequence 6 via our pulse oximetry checks in the end, however we’ve already examined a variety of fashions with this function – see beneath for hyperlinks to our evaluations.
Smartwatches and health trackers with built-in pulse oximetry
- Fitbit Charge 4 – £128. The newest member of the favored Fitbit Cost household. Can take night-time readings, however not on-demand, so it’s not helpful for alpine fanatics – however may choose up indicators of sleep apnoea (don’t deal with it as a medical gadget although).
- Garmin Venu – £300. A high-end health watch with a premium feel and appear. Can take on-demand pulse oximetry readings.
- Huawei GT2e – £118. A look ahead to health fanatics – once more, in a position to measure your pulse oximetry on-demand.
When you’re a wholesome individual, you shouldn’t need to buy a pulse oximeter, nor should you rely on one to detect coronavirus. However in case you’re a eager sportsperson who usually workout routines at excessive altitudes, a wrist-based pulse oximeter may assist you by flagging indicators that you simply’re over-exerting your self.
Coronary heart-rate monitoring on a smartwatch
Monitoring your coronary heart charge will help you be sure you’re pushing your self exhausting sufficient throughout your exercises, and, in case you control your heart-rate patterns long run, educate your self about your general cardiovascular well being.
Most wearables, apart from the ultra-cheap ones, provide heart-rate-monitoring now, however some go a step additional – for instance the Apple Watch Series 4 (£329), Apple Watch Series 5 (£399) and Apple Watch Sequence 6 can take ECG readings.
Coronary heart charge is taken utilizing sensors that measure electrical indicators in your coronary heart and verify for AFib (atrial fibrillation, irregular heart-rate rhythms). They’ll additionally ship you alerts in case your coronary heart charge goes above or beneath the traditional vary.
Dr Heather Morgan, lecturer in utilized well being sciences on the College of Aberdeen and a specialist in digital well being and health monitoring, informed us the Apple ECG function: ‘might be an amazing function in serving to to stop strokes. There have been a couple of circumstances the place the Apple Watch has picked up a difficulty as a ‘pre-screening’ instrument and the variety of inaccurate diagnoses appears low.
However she added: ‘It’s not one thing you should use to trace, monitor or handle a coronary heart situation. It tells you that you simply both have AFib otherwise you don’t, however not what variety it’s, or what remedy you would possibly want. Medical recommendation is at all times required and, as soon as a situation been recognized and is being medically managed, the function is ineffective.’

As far-fetched as that sounds, it’s actually only a case of analysing patterns in measurements – although that’s to not say it really works, or is correct. Wearables with these options measure stats comparable to your coronary heart charge and your coronary heart charge variability (HRV) – the variation in time between your heartbeats – and assign you a stress rating, though the identify could fluctuate from model to model.
They’ll then give you assist in the type of guided respiratory workout routines. If you breathe in a extra managed approach, you decrease your coronary heart charge and improve your HRV. And a few will use this info to offer you insights as to your readiness for a exercise.

With such a variety of expertise already accessible, and additional developments on the horizon, wearables have come a good distance because the days of cumbersome, restricted, glorified pedometers.
Dr Heather Morgan informed us: ‘Accuracy and tailoring of train monitoring knowledge is vastly improved and wearables can even carry out cardiograms, detect falls, let you know whenever you’re being uncovered to loud noise that might injury your listening to and a few are even being developed to incorporate proximity sensing programs to assist with contact tracing in the course of the COVID-19 pandemic’.
No shock, then, that the wearables expertise market is surging.
Info companies firm GlobalData says it expects smartwatches will more and more be utilized in healthcare within the subsequent 5 years, ‘pushed by enhancements in sensors and software program and rising client adoption’, and that we’re prone to begin seeing knowledge gathered by smartwatches getting used for early analysis and distant affected person monitoring.
We’ve additionally heard hypothesis that corporations and well being insurers, notably within the US, will take an growing curiosity in wearables – as wearables incentivise wholesome behaviour, and subsequently may cut back the quantity sick days an worker has to take or hospital visits she or he has to make.
