How It Works
- On average, it takes approximately 15 minutes for an individual to transition from wakefulness to sleep.
- A typical night of healthy sleep comprises 5 to 6 complete sleep cycles, each lasting around 90 minutes. These cycles include multiple stages, such as light sleep, deep sleep (slow-wave sleep), and REM (rapid eye movement) sleep.
- Disrupting sleep during the deeper stages of a cycle—particularly slow-wave or REM sleep—can result in sleep inertia, leading to grogginess and impaired cognitive function upon waking. In contrast, awakening between cycles, particularly during lighter sleep stages, promotes a smoother, more refreshed awakening.
- Sleeper Time utilizes sleep cycle calculations to estimate optimal wake times, aiming to minimize sleep inertia and support a more alert and restorative start to your day.
