Suunto 9 Peak Pro
NOTE: If you go to bed before your bedtime and also wake up after your bedtime, your
watch does not count that as a sleep session. You should set your bedtime according to the
earliest you may go to bed and the latest you may wake up.
Once you have enabled sleep tracking, you can also set your sleep target. A typical adult
needs between 7 and 9 hours of sleep per day, though your ideal amount of sleep may vary
from the norms.
Sleep trends
When you wake up, you are greeted with a summary of your sleep. The summary includes, for
example, the total duration of your sleep, as well as the estimated time you were awake
(moving around) and the time you were in deep sleep (no movement).
In addition to the sleep summary, you can follow your overall sleep trend with the sleep
widget. From the watch face, swipe left or press the middle button until you see the Sleep
widget. The first view shows your last sleep and a graph of the last seven days.
While in the sleep widget, you can swipe up to see the sleep details for your last sleep.
NOTE: All sleep measurements are based on movement only, so they are estimates that
may not reflect your actual sleep habits.
Sleep quality
In addition to duration, your watch can also assess sleep quality by following your heart rate
variability during sleep. The variation is an indication of how well your sleep is helping you
rest and recover. Sleep quality is shown on scale from 0 to 100 in the sleep summary, with 100
being the best quality.
Measuring heart rate and blood oxygen while sleeping
If you wear your watch during the night, you can get additional feedback on your heart rate
and blood oxygen level (needs to be activated in the sleep tracking settings) while sleeping.
To keep the optical heart rate on during the night, ensure that Daily HR is enabled (see 6.3.
Heart rate).
Automatic Do Not Disturb mode
You can use the auto Do Not Disturb setting to automatically enable Do Not Disturb mode
while you sleep.
