Using Nightly
Recharge™ to Check
Your Recovery
Status
With Nightly Recharge™, you can check how
much you have recovered from the load
placed on your body during the day.
The Nightly Recharge™ status is based on
two factors: Sleep Charge (the quality of your
sleep) and ANS Charge (how calm your
autonomic nervous system is during the early
hours of your sleep).
