Easyfit HR – Sleeping

How is sleep monitored?

The sleep monitoring mode is activated automatically at 9:00 pm and is automatically deactivated at 9:00 am. During this period, your Easyfit HR can automatically tell whether you are asleep or awake.

So you don’t have to worry about setting the sleep monitoring mode manually or deactivating it the following morning.

Can I record any sleep I get during the day?

Yes, simply activate the sleep mode on your watch manually.

To manually activate the sleep mode, follow these steps:

• Press down on the display of your watch
• Click on the Moon icon
• Press the display until you see “ON”

To manually deactivate the sleep mode, repeat the same steps. Remember to turn off sleep mode when you wake up from your nap.

What sleep-related information is collected?

The data on your sleep is used to determine your resting patterns. The algorithm can tell whether you’re sleeping deeply or lightly or even if you’re awake.

How are these states determined? When sleep monitoring mode is activated, every time the tracker doesn’t detect any movement for at least an hour it’ll assume that you’ve gone to sleep. Any arm movement during sleep will be interpreted as restlessness and the tracker will change from heavy to light sleep. You may not realise, but during sleep you might move or change position. Any very close-range arm movement during sleep phases is classified as being awake, so the algorithm will think that you’re awake for all intents and purposes.

This is the graph you’ll get the morning after your sleep analysis. The time slots begin when your first period of sleep is recorded, i.e. when the algorithm identifies that you haven’t moved your arm for about an hour. The time axis shows when a change of state occurred, i.e. each time you moved from a light or heavy sleep.

The system can also identify if you’ve woken up, perhaps to go to the bathroom, deactivating the sleep monitoring mode and activating the step counter.

Please remember that a few steps might also be counted even if you haven’t actually left your bed. This happens because certain arm movements, especially if very pronounced, may be interpreted by the algorithm as a step. Don’t worry if this happens: the number of steps calculated during the night accounts for the smallest figure which has a very low, almost negligible, effect on your daily exercise stats.
