Your internal clock (oh-oh!) Gets thrown by weekend sleep, so it's a shock!
Fun Fact
Social jetlag: Sleeping in just two hours later on weekends can shift your body clock as if you flew across two time zones.
Glossary
social jetlag (noun)
A mismatch between a person's biological clock and their social schedule, typically caused by differing sleep patterns on workdays and free days. German chronobiologist Till Roenneberg coined the term in 2006, explaining why early Monday alarms trigger severe exhaustion.
