IDA: Write an IDA comment on how this point relates to the topic and why it is an important point. Wider evaluation points: Individual differences: The effects of disrupting circadian rhythms vary between individuals. Practical applications: Jet lag: Consuming melatonin may help resynchronise the cycle more quickly. Beaumont et al (2004) found that taking melatonin at bed time for 3 days before travel and 5 days after significantly reduced the symptoms of jet lag Exposure to can affect circadian rhythms. Burgess et al (2003) investigated if jet lag could be prevented by phase shifting (advance or delay) before travelling. They found that after three days of light exposure in the morning, the participants’ circadian rhythms shifted by an average of 2.1 hours. This means they would feel less jet lagged, and would be fully adjusted to the new time zone around two days earlier. Shift work: The research can help both those planning work schedules and workers. Czeisler et al (1982) proposed that it would be better to rotate shifts forward in time so one begins with a day shift, progresses to an
