Circadian rhythm is the 24-hour biological clock that triggers your body to feel alert or drowsy at certain times of the day. Usually, your circadian rhythm aligns with the sun’s natural light and dark cycles, with peak drowsiness occurring around five o’clock in the morning. If your circadian rhythm no longer aligns with the sun’s natural light cycle, you may experience jet lag or excessive sleepiness at unusual times of the day.
Jet lag is most commonly associated with traveling across different time zones, as this kind of travel interrupts your natural circadian rhythm. One way to reduce jet lag is by avoiding light and exposing yourself to light at certain times of day. For example, you can train your circadian rhythm to align to a different time zone by exposing yourself to a commercially available light box or closing the curtains and keeping the room dark. In order for this to be effective, you need to research the time zone of the region where you are flying and slowly shift your rhythm to align with that time zone.
