An appropriate sleep routine can support the ideal situation of waking up from sleep feeling refreshed without needing an alarm clock.
Shift-working, and other life demands can prevent regular bed and waking times. This may at times cause disrupted or inadequate sleep. In these circumstances it best to do what is possible and not be concerned about achieving perfection.
