Sleep plays a major role in achieving your health and fitness goals.
Luckily, you don’t have to guesstimate, you can track your sleep data with the next evolution of sleep tracking – Polar Sleep Plus™ (available on the new Polar Vantage V and Polar Vantage M multisport watches, Polar A370 fitness tracker and Polar M430 GPS running watch).
Polar Sleep Plus in a nutshell
- An intelligent sleep system with Polar’s proprietary Polar Sleep Plus™ algorithm
- Based on your wrist movements and position
- See the timing, amount and quality of your sleep
- Rate your sleep
- Understand your sleep habits
- Get feedback on your previous night’s sleep
Tracking sleep to find answers
The new Polar Sleep Plus advanced sleep analytics helps you answer some basic questions you might have about your sleep, like:
- How much am I sleeping?
- What is my sleep routine like?
- Does this change I’ve introduced influence my sleep?
- Are there patterns to me sleeping poorly?
One of the main reasons we track something is so we can change it. The benefit of tracking your sleep with Polar Sleep Plus is that you can identify areas for improvement and introduce changes to your sleep habits.
Tracking sleep timing, duration and quality
This is the time between when you fell asleep and when you woke up. For example, you might go to bed at 9.51 p.m. and fall asleep at 10 pm. If you wake up at 6 a.m., your sleep time will be 8 hours.
During a normal night’s sleep there are usually several short and long interruptions. You can see these interruptions on the timeline as short or long yellow bars. The shorter interruptions we don’t usually remember but if you get up during the night to go to the bathroom, you’re more likely to remember it.
This is the time you were actually sleeping (sleep time minus interruptions). If your sleep time is 8 hours (from the previous example) and you toss and turn for a total of 59 minutes, your actual sleep is 7 h and 1 min or 87%.
Sleep continuity is a metric that describes how continuous your sleep was. It’s assessed on a scale of 1–5, with 5 being the best measure. The lower the value, the more fragmented your sleep was. You’ll also get one of the following assessments of your sleep continuity:
- Very continuous sleep (5.0)
- Continuous sleep (4.0–4.9)
- Fairly continuous sleep (3.0–3.9)
- Fairly fragmented sleep (2.0–2.9)
- Fragmented sleep (1.0–1.9)
There are no hard numbers as to what constitutes an objectively good sleep continuity grade. Once you track your sleep for days and weeks, you’ll start seeing where your baseline is.
Polar Sleep Plus will also give you feedback for every night you track. It considers your subjective feeling and sleep time preference as well as the objective sleep quality and duration metrics, tracked with the accelerometer.
Putting it all together
How rested you feel depends mainly on the duration and quality of your sleep. When assessing how well you’re sleeping, pay attention to the feedback you’re getting, your subjective feelings and the sleep quality metrics (percentage of actual sleep and sleep continuity).

Polar Sleep Plus enables you to tune into your sleep and understand what external factors may have an influence on your sleep. Do you travel a lot for work and tend to sleep less on those trips? Do you have more restful sleep at the beginning of the week vs. the latter because of a lighter workload? Do you sleep better when your bedroom is colder or hotter?
All of these questions, and more, can now be answered via sleep tracking with Polar Sleep Plus.
