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).
