Airplane travel and sleep disturbances caused by air travel are frequently reported. Passengers who travel regularly are likely to change time zones and can experience circadian rhythm misalignment, leading to jet lag disorder (JLD). The incidence of jet lag increases with the number of time zones crossed.
