Agree with all the above recommendations, but would add:
- 15-20 minute power naps can be preceded by caffeine to combine their benefits. This might help in the (unfortunate) tight hour you have between your shift (grab some coffee a you leave) and conference. Find a quiet, dark place to lay down, use
sound-isolating headphones and an eye mask, set a few alarms. Consider using a nap or sleep-tracking app for your alarm, as they can use either sound or your motion as a surrogate for your sleep depth and try to time your waking to be the least disruptive (within a preset window, e.g. 10 minutes).
- Try to take your daytime nap/sleeps in 90-minute intervals, as this is approximately the length of a typical REM cycle and will be the most restorative sleep. I aim for 4.5, 6, 7.5, or 9 hours between shifts.
- The typical human circadian rhythm is a little longer than 24 hours, so it's usually easier for people to extend their day a little longer than shorten it. i.e. It's usually easier to pre-sleep with some moderate length nap (as others have mentioned) before a night shift, rather than wake up and go right back to sleep really early to try to get 9 hours before your night shift.
- Reduce blue light exposure when you're going to need to sleep. I.e. blue-blocking glasses if you wear them,
dark sunglasses or blue-blocking glasses (google them) in the morning after your night shift, etc.
