A good night’s sleep isn’t a luxury. It’s a necessity.
Quality sleep is as important to health as a healthy diet and regular exercise. In fact, it affects how you look, feel, and perform on a daily basis and can have an immense impact on your long-term health.
While you sleep, your brain and body work together to rest and to recharge your body and mind. Sleep refreshes your brain, boosts your immune system, and repairs damaged cells. It also affects how you think, work, learn, react, interact, perform and feel throughout the day.

Five full sleep cycles per night is considered optimal, each lasting about an hour and a half. Within each cycle you progress from light to deep to REM sleep, sometimes followed by a short wake. While this is the typical progression, these stages aren’t always sequential. It’s quite common to switch from and to light sleep multiple times at night.
With the SleepScore daily report, you’ll be able to track your sleep cycles and use fact-based insights and ultra-personalized guidance to improve your sleep.
The four main stages of sleepwithin each cycle.
Considered your baseline, half of the time spent sleeping is in this restful stage. Your brain activity slows and your body relaxes as your heart rate and breathing decrease. It’s ideal to wake up from Light Sleep, and the SleepScore Smart Alarm is designed to help make that happen.
After going through your first light sleep, you enter a slow wave stage. Your brain waves, heart rate and breathing slow considerably as your blood pressure lowers and muscles relax. Deep Sleep is vital for physical and immune system restoration. Subsequently, it’s essential for memory, learning, next-day cognitive performance and the feeling of being refreshed and recharged the next day. After each cycle, your need for deep sleep diminishes, so time spent in this stage becomes progressively shorter.
After deep sleep, you enter periods of REM sleep that become progressively longer throughout each cycle. This is the mental restoration stage of sleep and where most dreaming occurs. Your brain activity levels increase significantly to help process, store and link information, which is critical for creativity, memory and learning. It also processes the emotional experiences of the day and prepares for upcoming challenges, which greatly impacts your emotional wellbeing. This cycle is more prominent in the later cycles.
While preparing for bed, your body starts in a state of wake as you enter the early onset into the light sleep stage. As you continue into the stages of your sleep cycle, you enter brief stages of wakening at night, between the other sleep stages, which is a normal part of sleep. Whether you realize it or not, while in light sleep, it’s not unusual for your body become more sensitive to short periods of wake.
