Getting enough good-quality sleep is vital for health and well-being. Polar’s Sleep Plus Stages™ sleep tracking offers you a full window to your night – it automatically tracks the amount and quality of your sleep and shows you how long you spent in each sleep stage.
Sleep plays an important role in optimal recovery. Many of the body’s restorative functions, such as muscle growth and tissue repair, occur mostly during sleep. Sleep is also important for the mental side of recovery: the amount and quality of sleep have a profound impact on learning and memory as well as mood and motivation.
When you want to improve or fine-tune your sleep, tracking it on a regular basis is the first step. Sleep tracking can help you identify the factors in your day that may have a negative impact on your sleep.
Sleep Plus Stages offers you a full breakdown of your sleep. It helps you dig deep into the details of an individual night and follow your long-term sleep habits.
When you sleep, your body goes through sleep cycles that consist of three sleep stages: light, deep and REM sleep. Sleep Plus Stages shows how long you spent in each sleep stage and counts your sleep cycles.
Sleep Plus Stages gathers your sleep time and sleep quality components into one easily glanceable value, Sleep Score. The Polar Flow app offers you a detailed breakdown of the quality of your sleep.
The Sleep Plus Stages algorithm has been validated against polysomnography, the current gold standard of sleep tracking. The results show that the algorithm determines sleep stages reasonably accurately.
Sleep Plus Stages is a completely automatic measurement – all you need to do is wear your watch when you sleep. It automatically recognizes when you fall asleep and when you wake up.
You’ll see a breakdown of your sleep on your watch and on the Polar Flow app. The Polar Flow web service shows your long-term sleep data.
Sleep plays an essential role in optimizing health and well-being. Good sleep hygiene is a step towards getting a great night's sleep and feeling fresh during the day.
