Frequently Asked Questions

What strategies can help with adjusting to a different sleep/wake pattern?

  • Light exposure, timed correctly within the circadian rhythm, is a powerful way of adjusting our internal body clock and adapting to a new sleep/wake routine.
  • Melatonin, a natural hormone produced by our bodies, also helps to regulate the body clock. Taking extra melatonin in tablet form, at the right time, may be helpful.
  • When travelling overseas, it is best to adjust to the new timezone (i.e. bedtime, wake time, meal times) as soon as possible. Some people find it helpful to alter their bedtime a day or two before they travel.
