Simply put, your circadian rhythm is your body’s 24-hour clock.

Throughout the day and night, your body goes through a number of processes. Hence why we feel alert, hungry and tired at certain points of the day.

Your circadian rhythm also works to control your blood pressure, temperature and hormone production. Without it, we wouldn’t know when we should sleep and when we need to wake up.

It’s basically an internal work schedule.

So, it’s important to keep it in sync.

The London Sleep Centre says that an unbalanced circadian rhythm can result in a few disorders, including jet lag, an irregular sleep-wake cycle and shift work-related circadian disorder.
