I Hated Wearing My Apple Watch to Bed Until I Learned About This Feature

howtogeek.com:

Aside from being a stylish accessory and a great workout companion, the Apple Watch is also a health-tracking device that you can wear to bed to track your sleep. You can set an alarm on your Apple Watch to wake you up on time, but I recommend you set a vibrate-only alarm for the best waking-up experience.

The Problem with Noisy Alarms

Despite owning an Apple Watch for almost a year, I still didn't wear mine to bed. I can do fitness trackers, like the Fitbit Charge 5, but the smartwatch form factor feels uncomfortable. However, I decided to wear one for a week to check its sleep-tracking prowess.

The first couple of days, I woke up feeling groggy because of the jarring alarm sound my watch made to wake me up. Fortunately, I soon learned that I could set a silent (or vibrate-only) alarm on an Apple Watch. As soon as I set the alarm to vibrate mode, I saved the rest of my mornings.

If you, too, hate waking up to an audible alarm, you should consider setting a silent or vibrate-only alarm on your Apple Watch. You may also find the silent alarm feature on your Apple Watch useful if you share your bed or room with someone and don't want to wake them up with your alarm. Or if you use alarms instead of reminders to remind yourself to get things done.

Set a Silent Alarm on an Apple Watch Directly

Apple lets you set a silent alarm directly on the Apple Watch, which is useful when you don't have your iPhone nearby.

To do this, press the Side button on your Apple Watch (below the Digital Crown) to bring up the Control Center. Then, tap the bell icon to turn on Silent Mode.

Exit the Control Center by pressing the Side or Digital Crown button. Tap the Digital Crown button again to view all your apps and open the Alarms app.

Click the plus (+) icon to create a new alarm.

Set the time you want the alarm to go off.

Finally, hit the green tick icon in the lower-right corner of the screen to set the alarm.
