Tracking your workouts, runs and steps may be the main reason you asked your Santa for a smart watch this Christmas (if it's not logged on Strava, it didn't happen, right?). But you can actually use your shiny new top smart watch to sleep better at night too.
I spent the last year testing the best sleep trackers on the market and found many popular smart watches from the likes of Apple and Garmin came out on top. Along the way, I've learnt how to use data collated by these trackers to achieve better rest at night.
