All humans (in fact, most living organisms) have an “internal” clock that tells us when to sleep and when to wake

This process is called a Circadian rhythm. It is influenced by light and darkness, and generally follows a 24-hour cycle. If your Circadian Rhythm is out of sync, it can result in issues such as insomnia and/or excessive daytime sleepiness. The cause can be external (such as jet lag, a time change or shift work).
