Jet lag and other sleep disorders relevant to the traveler

Abstract

Sleep and wakefulness are governed by homeostatic and circadian regulatory processes, and perturbations therein are primarily responsible for the sleep disturbances associated with travel. Misalignment between endogenous rhythms and the light/dark cycle can result in circadian rhythm sleep disorders, including jet lag. This condition will be the primary focus of this review, with an emphasis on predisposing factors, preventative options, and treatment strategies.
