Polar Sleep Plus™
Elements of your sleep visualised
Polar Sleep Plus™ sleep tracking helps you visualise the elements that make up for a good night’s sleep. Find out what your sleep habits, sleep duration and sleep quality are like and fine-tune them, if you feel that’s necessary.
Do remember though that sleep is not a performance. There are things you can do to make falling asleep and sleeping better easier, but being stressed is sleep’s enemy, so the trick is to always stay relaxed about it.

Track, then hack
Establishing a regular sleep routine and developing good sleeping habits is important for the duration and quality of sleep. Polar’s Sleep Plus™ makes this process easier by equipping you with all your sleeping habit metrics. You can then hack your habits, if that’s necessary to get better quality of sleep.
Ingredients of sleep quality
Polar Sleep Plus™ tracks the ingredients that together make up sleep quality: the percentage of actual sleep and the continuity of your sleep. These are visualised in daily and weekly stats.

No rest, no gain
To be able to achieve your training goals, you’ll want to make sure your sleep and rest are as restorative as possible. Recovery from training is perfected with a good night’s sleep.

The Science
Polar Sleep Plus™ has been validated against polysomnography in children, adolescents and adults. Polysomnography is considered the gold standard method to assess sleep. It measures brain activity, muscle activity and eye movements and requires manual scoring of sleep and wake states.
Results from the validation studies suggest that Polar Sleep Plus™ detects sleep and wake as accurately as the current, commonly used wrist-worn devices, in research and clinical practice.

Wear watch and follow stats
Just wear your Polar watch around the clock. Choose your sleep time preference: how much sleep you need to feel rested in the morning. The general recommendation for healthy adults is from 7 to 9 hours of sleep.
Give your self-evaluation every morning and follow your daily and weekly sleep feedback and sleep patterns, as well as your self-evaluations, in Flow app or web.
