Why 5:45 AM matters for an early shift

5:45 AM isn’t random. It lines up with your early shift, a calm commute, and a clean handoff into the first 90 minutes of work. It’s the anchor that keeps you from sprinting the moment the alarm ends.

Runs in your browser. Sound may require a click/tap to activate. This preset minimizes snooze cycles and primes you to show up present.

Morning routine

Use this routine right after the alarm to lock in momentum for the first hour.

Hydrate immediately: drink 8 oz water within 2 minutes of waking at 5:45.
Move for 5 minutes: 30 seconds of brisk march, 30 seconds of arm circles, repeat.
Light cue: stand by window and open blinds for 2 minutes to cue wakefulness.
Prep for shift: lay out uniform, badge, and bag with a 60-second checklist by 5:58.

Sleep-cycle suggestion

Optional. If you want to chase sleep-cycle alignment, this is optional and not medical advice.

Bedtime targets for waking at 5:45: for 4 cycles, aim for 11:45 PM; 5 cycles, 10:15 PM; 6 cycles, 8:45 PM.

Time zone note

Alarms rely on your device/browser time. Make sure this tab stays active or open. If you switch apps, the alarm may not fire exactly at 5:45 unless the tab remains loaded.
