BBC News reports on a review paper published in this week’s Lancet on the effects of jet lag – which can include mood changes, cognitive impairments, disruption to the menstrual cycle and psychotic experiences.
Disrupted sleep is often linked to psychosis, and interestingly, both airports and jet lag have been mentioned in the medical literature in relation to this.
In a curious 1982 paper, Shapiro reported a series of cases where individuals with psychosis were found wandering airports, and suggested, rather boldly, that ‘airport wandering’ could be a psychotic symptom.
Nevertheless, some more recent research has suggested this isn’t as far-fetched as it sounds.
A 2001 study by Udo Wieshmann and colleagues looked at people treated for severe mental illness over a four year period at Heathrow Airport.
Although the rate was very low (less than one in a million passengers), for those that did show signs of psychosis, ‘airport wandering’ was one of the most frequent symptoms.
The fact that being jet lag can also cause temporary or transient psychosis-like experiences in some people, as reported in The Lancet paper, suggests that sleep disruption may play a part in both minor and major reality distortions.
Luckily, this week’s mp3 podcast from The Lancet interviews one of the study authors who talks about the health effects of jet lag, and also gives advice on coping with it as effectively and healthily as possible.
