Sleep score radar chart is another way of looking at your sleep score.

You can fill each of the sleep score section with up to 5 points. The more points you have in a given section, the more healthy that dimension of your sleep is.

How should it look?

The goal is of course to fill up that chart completely!

Deficit chart is useful for tracking your sleep deficit.
- Blue line: shows the deficit on a given day. If you sleep less then your Daily sleep duration goal, the blue line will be negative on that day. If you sleep more, it will be positive.

How should it look?

You should strive to have zero sleep deficit, so ideally all of the lines should aim to be around 0 hours all the time.

Duration chart shows you the evolution of your sleep lengths.

How should it look?

The chart should not have many extremes (regular, periodic chart is normal).

Irregularity chart shows you how much is your sleep irregular. The higher the line is, the more irregular your sleep is.

How should it look?

While some irregularity is normal, you should strive to keep it to minimum - keep the line at low values.

Deep sleep % chart shows you how your deep sleep percentage has been changing recently – effectively how well did you sleep.

Deep sleep percentage means "a portion of your sleep duration when you’ve been in deep sleep". So if you had an 8-hour slumber, 50% deep sleep percentage would mean 4 hours in deep sleep. So what this graph shows is how effectively are you able to sleep.

How should it look?

The average should be kept over 30%.

Deep sleep chart shows you how your deep sleep duration has been changing recently.

This graph shows how many hours of deep sleep have you been getting recently.

How should it look?

The graph should not have many spikes - ideally should be regular, flat line, above 2 hours.

Awake chart shows you how much you’ve been waking up during your sleep.

How should it look?

In an ideal world, you should not wake up at all during sleep. This means a flat line at the bottom.

Efficiency chart shows the ratio of actually sleeping when you’re in bed (sleep duration to tracking duration).

How should it look?

Ideally a flat line at 100%.

Snoring percentage chart shows how much of the time you sleep did you spend snoring.

How should it look?

Ideally a flat line at 0%.

Snoring chart shows how much time did you spend snoring.

How should it look?

Ideally a flat line at 0 minutes.

Graphs, or "sleep bars", show the intensity of movement during sleep. Each bar is one sleep. At the bottom, the charts start with 12PM and go up to the next 12PM. The greener the bar is at any given point, the more intensive movement there was.

How should it look?

As the sleep bars are just another view at the actigraph, they should ideally follow the same rules as the actigraph: they should show regular sleep cycles that get shorter towards the end of the sleep.

Fall asleep hour chart shows when you’ve been going to bed.

How should it look?

Ideally a flat line with no spikes.

Smart wakeup shows how many minutes before the set alarm did smart wake up wake you up - ie. the efficiency of smart wake up for you.

How should it look?

It should be consistently between zero and your set smart period. If it’s at one of the extremes, you should adjust the smart wakeup sensitivity.

Snooze chart shows how many minutes you’ve been snoozing your alarm.

How should it look?

There are no hard and fast rules on snoozing, but it sure is a sign of a strong willpower to keep it at zero!

HRV chart shows total amount of heart rate variability throughout the entire night, including all the local minima and maxima

How should it look?

Generally, the higher the better, but ideal HRV is highly individual - your age, gender, fitness level, and fitness activity play the key roles. You should be looking for increasing trend in your HRV data.

HRV gain chart shows the difference between your HRV measured during the first low activity period (hrv before) of your sleep and the HRV measure at the last low activity period before awake up (hrv after) (see details here).

How should it look?
It should be consistently in the purple positive spectrum.

HRV Before wake up chart shows HRV before wake up for given day (when date range is quarter-year or lower) or a 30-day average (when date range is half-year or higher).

How should it look?
Like HRV, HRV before wake up is highly individual measure, higher numbers are more favourable.

Respiratory disturbances chart shows

How should it look?

Ideally, there are no respiratory disturbance during you sleep, so a flat line at zero.

Shows where your all-time average mid-sleep hour stands in comparison to other people (data taken from SleepCloud). Your mid-sleep hour is highlighted.

If your mid-sleep hour is more to the right, you are a night owl. If it’s more to the left, you’re a morning lark.

Shows the evolution of your chronotype. If you switched chronotypes at some point, there might’ve been some specific event like job change etc.

Shows your sleeps as points in an XY graph, in order to find your social jet lag.

Most importantly, the sleeps are divided into two clusters - Working days and Free days (see explanation)

How should it look?

Ideally, the two clusters should be very close together, indicating that your social jet lag is very low.

Shows you mid-sleep hour on free days and workdays, and your social jet lag.

How should it look?

Ideally, the two leftmost bars should be very similar in height, so your social jet lag would be very low.

Fall asleep hour regression model is a chart that helps you decide when you should go to sleep. The aim of this chart is to show you how changes in your fall asleep hour will affect your rating and deep sleep %.

How do we know that? A regression model takes the existing (historical) data, filters out outliers (i.e. extreme values) and then finds a mathematical formula that best fits that data. On the basis of this formula, it is possible to statistically predict future behavior.

You can see two sets of points, and up to two curves.

Take a look at the curve (either blue or orange) and focus on the maximum point or points. At what position (what fall asleep hour) it is? You should go to bed at this hour in order to maximize your deep sleep % (in case of blue line) or rating (in case of orange line).

Duration regression model is a chart that gives you advice on how long should you sleep. The aim of this chart is to show you how changes in your sleep duration hour will affect your rating and deep sleep %.

How do we know that? A regression model takes the existing (historical) data, filters out outliers (i.e. extreme values) and then finds a mathematical formula that best fits that data. On the basis of this formula, it is possible to statistically predict future behavior.

You can see two sets of points, and up to two curves.

Take a look at the curve (either blue or orange) and focus on the maximum point or points. At what position (what sleep duration) it is? You should try to sleep for that long in order to maximize your deep sleep % (in case of blue line) or rating (in case of orange line).

Shows you average values of deep sleep % / rating for sleeps that started at a given fall asleep hour.
