Physiological changes underlying jet lag.

Jet lag.

INTRODUCTION Jet lag affects most air travellers crossing five or more time zones; it tends to be worse on eastward than on westward flights. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent or minimise jet lag? We searched: Medline, Embase, The Cochrane Library, and other important data...

Jet Lag in Athletes

CONTEXT Prolonged transmeridian air travel can impart a physical and emotional burden on athletes in jet lag and travel fatigue. Jet lag may negatively affect the performance of athletes. STUDY TYPE Descriptive review. EVIDENCE ACQUISITION A Medline search for articles relating to jet lag was performed (1990-present), as was a search relating to jet lag and athletes (1983-January, 2012). Th...

Jet lag modification.

Athletes often are required to travel for sports participation, both for practice and competition. A number of those crossing multiple time zones will develop jet lag disorder with possible negative consequences on their performance. This review will discuss the etiology of jet lag disorder and the techniques that are available to shorten or minimize its effects. This includes both pharmacologi...

Jet Lag and Sleep Deprivation

Circadian rhythm desynchronosis, jet lag, shift lag, and coping strategies.

Jet lag and shift lag have similar physiological consequences, but shift lag is a more complex problem. The most severe desynchronization may be experienced by airline personnel making transmeridian flights. Coping strategies for eastward and westward travelers and for shiftworkers are recommended, as are interventions involving melatonin.
