{{Short description|Telephone service allowing one to wake up at a specified time}} {{other uses|Wake Up Call (disambiguation)}} {{Refimprove|date=September 2017}} A '''wake-up call''' ('''alarm call''' in the United Kingdom, '''morning call''' in east Asia) is a service provided by lodging establishments allowing guests to request a telephone call at a pre-specified time, thus causing the guest to wake up at that time. It is similar in concept to an alarm clock, but is instead conducted via a telephone.
The phrase has also been used to describe an alert someone may receive regarding the consequences of negative circumstances or dangerous behavior.<ref>{{Cite book|editor-last=Pickett|editor-first=Joseph P.|title=The American Heritage Dictionary|year=2000|publisher=Houghton Mifflin|location=Boston|isbn=978-0-395-82517-4|url=https://books.google.com/books?id=GsgqnwEACAAJ}}</ref>
Wake-up calls are also used in aircraft crew rests during long-haul flights to wake up resting flight attendants or pilots from their controlled rest.
