[Jet leg]

Abstract

The aim of the paper is to give a review of jet-lag (Time Zone Change Syndrome) with regard to aetiology, symptomatology and pathophysiology. Furthermore we give recommendations on treatment of jet-lag. The literature has focused intensely on the potential benefit of phototherapy and/or use of melatonin as treatment modalities for jet-lag. Both phototherapy and melatonin have the capability to accelerate reentrainment of the circadian rhythm after flights across multiple time zones, thereby reducing jet-lag. We stress the importance of correct timing of phototherapy and use of melatonin and suggest that the traveller adapts to the "social" rhythm at the flight destination as well.
