What works for jetlag? A systematic review of non-pharmacological interventions

Jetlag is a combination of travel fatigue and circadian misalignment resulting from air travel across time zones. Routinely recommended interventions based on circadian science include timely exposure to light and darkness (scheduled sleep), but the real-world effectiveness of these and other non-circadian strategies is unknown. We systematically reviewed the evidence for non-pharmacological interventions for jetlag. PubMed, EMBASE, Scopus, and Web of Science were searched. Studies reviewed (i) involved human participants undergoing air travel with a corresponding shift in the external light-dark cycle; (ii) administered a non-pharmacological intervention; (iii) had a control or comparison group; and (iv) examined outcomes such as jetlag symptoms, sleep, cognitive/physical performance, mood, fatigue, or circadian markers.
