Nightly Recharge™ Recovery Measurement - Polar Electro Ignite 3 User Manual

NIGHTLY RECHARGE™ RECOVERY MEASUREMENT
​ N ightly 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.
