“I want to track my sleep”

If you are interested in tracking your sleep with a wearable, it is important to monitor for sustained, meaningful changes in sleep/wake behaviour.

Most wearables use automatic detection of sleep to initiate sleep data collection. Unless you are particularly concerned about how long it is taking you to fall asleep, you can use this automatic function, but monitor the following:

1. Check whether the sleep/wake times line up with when you went to bed and when you woke up. If the results seem incorrect (e.g., sleep time is 1 hour before you attempted to sleep), manually adjust the sleep period to reflect the correct timing. Such misestimations may be due to wearable placement, or pre-sleep behaviour (e.g., watching a movie in bed).
2. Even though wearables are improving their ability to measure sleep stage, place more importance on tracking sleep timing (try keep consistent where possible) and total sleep.
3. If sleep/wake timing and total sleep time show meaningful changes over a sustained period of time (and data appear to line up with your behaviours), seek advice from your support team.
