Every night we go through different phases of sleep - from light to deep. The secret to waking up rested and feeling more energetic and alert upon awakening is to wake up during a period of your lightest sleep.

In the morning, you also get a nightly record of your sleep in the form of a graph showing the quality of your sleep.
