Early investigators determined the human circadian period to be 25 hours or more.
They went to great lengths to shield subjects from time cues and daylight, but they were not aware of the effects of indoor electric lights.
The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep.
Electric light in the evening delayed their circadian phase.
These results became well known.

Oooh. Dangerous. I can't have naps, they make me upset. Well, not the naps, but the people telling me it's still the same day as it was when I fell asleep. I get quite violently offended by those sorts of lies *not very good at being nice or sane post-waking*.

For example, appropriately timed treatment with angiotensin converting enzyme inhibitors (ACEi) may reduce nocturnal blood pressure and also benefit left ventricular (reverse) remodeling.
There are many health problems associated with a disturbance in the human circadian rhythm, such as seasonal affective disorder (SAD), delayed sleep phase syndrome (DSPS) and other circadian rhythm disorders.
Circadian rhythms also play a part in the reticular activating system which is crucial for maintaining a state of consciousness. In addition, a reversal in the sleep-wake cycle may be a sign or complication of uremia, azotemia or acute renal failure.

there's only a few studies that I have to pay attention to, and this isn't one of them.

Disruption to rhythms usually has a negative effect. Many travelers have experienced the condition known as jet lag, with its associated symptoms of fatigue, disorientation and insomnia.
A number of other disorders, for example bipolar disorder and some sleep disorders, are associated with irregular or pathological functioning of circadian rhythms.
Recent research suggests that circadian rhythm disturbances found in bipolar disorder are positively influenced by lithium's effect on clock genes.

Stick that in your Circadian rhythm!
