Polar Sleep Plus™ FAQs
Applies to: M430 Vantage M Vantage V
Sleep Plus automatically detects when you fall asleep, and when you’re sleeping based on the movements of your non-dominant hand with a built-in 3D accelerometer in your Polar device. You do not need to activate a separate sleep mode nor indicate when you’ve woken up.
Sleep Plus does not detect naps, so an afternoon nap, for example, is not included in the Sleep Plus metrics.
Your sleep time, in other words the duration between when you fell asleep and woke up must be at least 4 hours to get Sleep Plus metrics.
Sleep Plus also recognizes if you sleep during the day so it also works for shift workers. If your longest sleep span is during the day Sleep Plus will spot it. However, Sleep Plus detects only one sleep span, the longest one, per day.
The time of the day you sleep does not affect the sleep detection. It only affects to which calendar day your sleep is logged in the Flow web service and app.
You can adjust your sleep in the Flow app on your mobile phone and make the following changes:
- Change the sleep timing of detected sleep or revert to the originally detected sleep
- Add new sleep
- Delete one sleep period at a time
