Travel and Performance

Changes in the light/dark cycle have profound effects on man's circadian rhythms, particularly when he is required to work or perform adequately in a new time environment. These changes include effects on sleep, mental performance, including judgement and decision-making, and on physical performance. Whilst changes in physical performance are difficult to measure, the effects may influence athletic performance. Athletic teams performing in a new time zone should therefore be flown out well ahead of the planned event to ensure adequate circadian resynchronization.
