Should I sleep before or after my night shift?

The Full Answer

The answer depends on where you are in your shift block:

Before your first night shift: Take a 60-90 minute nap in the late afternoon (4-6pm). This 'prophylactic nap' provides a buffer of alertness for your first night, which is typically the hardest because you have been awake on a normal schedule. Do not try to sleep all day before your first night. It rarely works and you waste the day.

Between consecutive night shifts: Sleep as soon as possible after arriving home. Your primary sleep block should start within 60-90 minutes of getting home. This is when sleep pressure is highest and your body is most willing to cooperate. Delaying by even 2-3 hours risks getting a second wind.

After your last night shift: Sleep for a shorter block (4-5 hours) to build up sleep pressure for an earlier bedtime that evening. This is the recovery transition. You are shifting your sleep window back toward normal.

The key principle: your main sleep block always comes after your shift. Pre-shift naps are supplements, not replacements.
