If you’re wearing a fitness tracker right now, chances are it’s packed full of sensors. These sensors can measure your sleep, record your steps and your workouts, take a heart-rate reading and keep tabs on how many calories you burn throughout the day.

If you’re lucky enough to have the newest Apple Watch Series 6 strapped to your wrist, you can also measure the oxygen saturation in your blood or take an electrocardiogram (ECG) reading to gauge the electrical activity of your heartbeat.

Tracking and accessing all of this data gives people interested in fitness more accurate measurement tools. It provides those living with health issues options to take monitoring into their own hands. And it’s also a dream come true for gadget lovers who are curious to find out more about their health and their bodies with the help of tech.

However, the wealth of data our tracking devices and monitoring apps present us with at the push of a button – often, you don’t even have to push a button, the screen comes on with the flick of your wrist – can feel overwhelming. This might lead to a not-so-healthy preoccupation with numbers, stats and optimisation.
