The human body follows a sleep-wake cycle – the circadian rhythm – that determines when it is time to sleep, and when it is time to wake up. It is the 24-hours sleep pattern that consists of approximately 16 hours of wakefulness in the day and 8 hours of sleep at night. The disruption of this biological sleep-wake timing is called circadian disruption.
If you are not getting enough hours of sleep, or are sleeping during the daytime, your circadian rhythm will be impacted. The factors causing circadian disruption could be, travel (jet lag), working in the night shift, etc. Disruption of the sleep-wake cycle can affect your health. Studies have shown that disrupted circadian rhythm can result in weight gain, slower thinking, an increase in impulsiveness, etc. Having a normal circadian rhythm is essential to healthy living.
