How does the Smart Alarm work?

It is more or less easy to wake up depending on our current sleep stage.

During deep slow wave sleep, the brain acts as a filter, by not paying attention to certain nuisances (light, noises, ...) so that we remain asleep. But, a sufficiently strong stimulation (like an alarm) can wake you up. Which is a pain because we’ll feel sleepy and lethargic afterwards.

It is slightly easier to wake up during Rapid Eye Movement (or paradoxical) sleep (In 90% of cases of waking up in this stage result in being able to remember your dream).

Last, but not least, it is much easier to wake up during light sleep. We feel alert and refreshed.That is why the Smart Alarm tries to wake you up during such stages.

For example, if you set it to 7:30am, it will detect the best moment to wake you up (during a light sleep stage) depending on the wake window (X minutes before 7:30am) that you chose in your app. If you remain in a deep sleep state until 7:30am, your Smart Alarm will act like a normal alarm and will wake you up at 7:30am.

The Smart Alarm will be triggered in the following situations:

  • You are already starting to wake-up during the selected window and before you start to sleep again.
  • You are in the light sleep phase and are about to change your sleep phase (deep or paradoxical).
  • In all other cases, the Smart Alarm will ring at the set time.

To interrupt the alarm, press the button. The alarm will be automatically postponed by 10 minutes, unless if the headband detects that you fall back asleep (in that case, it will ring sooner). 

Please note:
  • You can’t set an alarm in Relax mode.
  • Make sure to set the volume of your alarm when launching your night.
  • Your Smart Alarm will not ring if you take off your Dreem Band before the set time or if your recordings has stopped during the night.
