Frequent questions about Dreem Coach data

How do the sleep is uploaded to the app? 

When you spend a night with the headband, it records a lot of data. When you finish your night, the connected headband activates the wifi, and sends all of this data to both our secure server and your application.

What to do if the data take a long time to appear on the app?

If your data take a long time to appear on the app, it may mean that your headband is not connected or that your smartphone does not have a good connection (Wifi or 4G).

Why can't I see my sleep objective on my night cards?

This is probably because you have not passed the evaluation stage yet. Once this step is over, you can set a goal and follow it on your night cards. Learn more about setting a sleep goal.

Is it possible that sleep data (sleepiness, awakenings) do not match my feelings?

Yes. Between your feeling and the objective sleep data reported on the application, you may notice a discrepancy. Several reasons for this:

It is sometimes difficult to be aware of certain highlights such as awakenings, agitation or the time of falling asleep
The headband was not properly positioned throughout the night and had difficulty reporting your sleep data. To learn more about how Dreem's algorithm works, see our dedicated article

Is it possible to link my data with other connected devices?

No, it is not possible to connect Dreem data with applications from other connected devices. On the other hand, you can fully contact our support team, request an export of your sleep data and make reconciliations with data from other devices.

I only see the mention of stimulations on my weekly sleep report, is this normal?

You can also find your daily data of deep sleep stimulations on the hypnogram, pressing the night card, then choosing the deep sleep phase. The impact, on the other hand, is visible at the level of the sleep ratio, insofar as the impact of stimulation is not relevant at night.

What are the indicators of a good or bad night?

The best way to analyze your night is to consult the quality radar, as well as the number of hours of effective sleep, indicated in the night card. You can also analyze the quality of your nights as well as its progress when reading the sleep report.

How is the sleep time calculated?

The duration of sleep does not correspond to the whole period preceding the first of sleep but to the duration between the first occurrence of the closed eyes and the first phase of consolidated sleep.
