Suppose you are taking part in a study of circadian rhythms. You have been asked to live in a special room in which there are no windows, clocks, or watches, and no access to time cues of any sort. How will these conditions affect your biological clock?

In the absence of external cues, the human biological clock tends to run on a cycle that is slightly longer than 24 hours, typically around 24.2 to 24.5 hours. This phenomenon has been observed in numerous studies involving environments isolated from natural light and time cues.  Without external time cues that help us adjust to a 24-hour cycle, it is likely that our internal clock will establish a 24.18-hour cycle. Our exposure to sunlight helps us make the slight adjustment each day.
