«Our circadian rhythm or body clock plays an important role in the timing of our sleep period,» says Dr Helen Wright from the School of Psychology at Flinders University.

Your brain has a clock (circadian clock) which controls hormones in your body that tell you it's time for you to go to bed.

Jet lag occurs when that body clock is disrupted when transitioning through time zones, disrupting our circadian rhythm, and can often take a few days to rectify.

Going to sleep and waking up at the same time every day — even on weekends — is crucial for setting your body's internal clock, which experts call your circadian rhythm.

Your circadian rhythm (aka your «internal body clock») relies on consistency, so going to bed and waking up at the same time each day will align your body to these rhythms.

Since our circadian rhythm is strongly influenced by light, exposing yourself to bright light at certain times in the day is a powerful way to shift your internal clock.
