Abstract
Rapid long-haul flights lead to jet-lag or circadian
dyschronism, characterised by various symptoms
including fatigue (and yet inability to sleep at the new
night-time), headache, irritability, loss of concentration,
and gastrointestinal disorders (indigestion, loss of appetite,
and bowel irregularities).
No agreement exists as yet for standardisation of the
symptoms of jet-lag. Comparison between studies can,
therefore, be difficult. A more systematic approach to the
problem has been adopted by Spitzer and colleagues,
5
who
obtained a high internal consistency with the items fatigue,
difficulty in concentrating, clumsiness, decreased alertness
in the daytime, difficulty with memory, general weakness,
dizziness, lethargy, and daytime sleepiness.
