Measuring heart rate while sleeping
If you wear your watch during the night, you can get additional feedback on your heart rate
while sleeping. To keep the optical heart rate on during the night, ensure that Daily HR is
enabled (see 3.1.2. Daily HR).
Automatic Do Not Disturb mode
You can use the auto Do Not Disturb setting to automatically enable Do Not Disturb mode
while you sleep.
3.32. Sport modes
Your watch comes with a wide range of pre-defined sport modes. The modes are designed
for specific activities and purposes, from a casual walk outside to a triathlon race.
When you record an exercise (see 3.28. Recording an exercise), you can swipe up and down
to see the short list of sport modes. Tap the icon at the end of the short list to view the
complete list and see all sport modes.
Each sport mode has a unique set of displays as well as options you can modify in the watch.
3.33. Swimming
You can use your Suunto 9 for swimming in pools or openwater.
When you use a pool swimming sport mode, the watch relies on the pool length to determine
distance. You can change the pool length as needed under the sport mode options before
you start swimming
Openwater swimming relies on GPS to calculate distance. Because GPS signals do not travel
under water, the watch needs to come out of the water periodically, such as with the freestyle
stroke, to get a GPS fix.
These are challenging conditions for GPS, so it is important that you have a strong GPS signal
before you jump in the water. To ensure good GPS, you should:
•
Sync your watch with your online account before you go swimming to optimize your GPS
with the latest satellite orbit data.
•
After you select an openwater swimming sport mode and a GPS signal is acquired, wait at
least three minutes before starting your swim. This gives the GPS time to establish strong
positioning.
3.34. Stress and recovery
Your resources are a good indication of your body's energy levels and translate into your
ability to handle stress and cope with the day's challenges.
Stress and physical activity deplete your resources, while rest and recovery restore them.
Good sleep is an essential part of ensuring your body has the resources it needs.
