NIGHTLY RECHARGE™ RECOVERY MEASUREMENT
Nightly Recharge™ is an overnight recovery measurement that shows you how well you recover from the demands of
your day. Your Nightly Recharge status is based on two components: how you slept ( sleep charge ) and how well
your autonomic nervous system (ANS) calmed down during the early hours of your sleep ( ANS charge ). Both
components are formed by comparing your last night to your usual levels from the past 28 days. Your watch
automatically measures both sleep charge and ANS charge during the night.
You can see your Nightly Recharge status on your watch and in the Polar Flow app. Based on what we've measured from
you, you get personalized daily tips in Polar Flow app on exercise, and tips on sleep and regulating your energy levels on
those particularly rough days. Nightly Recharge helps you make optimal choices in your everyday life to maintain overall
well-being and reach your training goals.
How to start using Nightly Recharge?
1. Continuous heart rate tracking needs to be enabled for Nightly Recharge to function. To
enable Continuous HR tracking go to Settings > General Settings > Continuous HR
tracking and choose On or Night-time only .
2. Tighten the wristband firmly around your wrist and wear the watch when you sleep. The
sensor on the back of the watch must be in constant touch with your skin. For more
detailed wearing instructions, see
Wrist-based heart rate measurement .
3. You need to wear your watch for three nights before you start to see the Nightly
Recharge status on your watch. This is how long it takes to establish your usual level.
Before you get your Nightly Recharge you can view your sleep and ANS measurement
details (heart rate, heart rate variability and breathing rate). After three successful nightly
measurements you can see your Nightly Recharge status on your watch.
