This often applies to night work, later shifts or a flexible schedule. The challenge is protecting sleep when an early morning might otherwise cut it short.
A late bedtime does not automatically mean poorer sleep if you can wake sufficiently late. Avoid cutting the night short with an unnecessarily early alarm.
