Your first two cycles usually contain the most N3 (deep) sleep,
and that’s when the body repairs muscles, regenerates cells, and restores immune function.
So, for quality sleep:
👉 At least 2 full deep sleep cycles (≈ 3 hours total) is essential,
but 5 complete 90-minute cycles (≈ 7.5 hours) gives your body full recovery and mental restoration.
BUT❗Here’s the catch:
Most people today struggle to reach or sustain the N3 stage — the one responsible for cell repair, hormone balance, and energy restoration.
That’s where AmLife’s DeepZleep therapy steps in.
By aligning with your body’s natural bioelectric rhythm, DeepZleep helps you enter and maintain deeper N3 stages more consistently throughout the night — meaning more healing, less tossing, and genuine morning energy.
