Adolescents and young adults may have a schedule that disrupts a regular sleep pattern. While referred to as social jet lag, this has nothing to do with travel between time zones. It can lead to fatigue and a number of health problems.

Features of social jet lag:

(1) one sleep schedule during the week while working or going to school

(2) vastly different sleep schedule on the weekend, typically going to bet much later than during the week

(3) consequences of switching between sleep schedules (poor sleep quality, daytime sleepiness, fatigue, poor eating habits with weight gain)


This is related to shift work sleep disorder (circadian rhythm sleep disorder).
