Does it make sense to track your sleep?

Contact sensors, like smartwatches or bands, aren't as precise as professional equipment. If you blindly trust the numbers from your sleep tracker, you might end up with a wrong self-diagnosis. It could indicate a bad night even if you wake up feeling well-rested. Bet you'll suddenly feel tired, right? Therefore, make sure you can interpret the data accurately before you change your daily routine or consult a doctor.

Another tip: don't compare yourself too much to others, but mainly focus on your own measurements. If a sleep tracker indicates that you've had a rough night and are recovering worse than usual, consider it as a helpful new insight that you can work with. It's a bit of awareness. Are you indeed not sleeping or recovering well? What lifestyle adjustments can you make to improve that?

Sure, but take the measurements with a grain of salt. Especially if you know you have a lot of interruptions in your sleep. Use them primarily as support to become more aware of your own sleep, so you can learn more about your sleep (pattern).
