I have read much literature that disturbing the normal circadian rhythms can really wreak havoc on you--including a higher incidence of breast cancer for those women who work the graveyard shift, as well as trigger psychiatric episodes--so yeah, let's fuck with an entire prison population and see what happens.:eyes:
Hey wait--I have a better idea. Why not just early release the non-violent criminals??

Davis and colleagues found that women who worked the graveyard shift at least once during the decade before breast-cancer diagnosis were at approximately 60 percent increased risk for breast cancer compared with those who did not work the graveyard shift. In addition, the risk of breast cancer significantly increased with each additional hour per week of graveyard-shift work.
The link between sleep, light at night and breast cancer may involve melatonin, a hormone produced by the brain's pineal gland. Production of melatonin peaks at night during sleep. One theory is that nighttime sleep deprivation or exposure to light at night somehow interrupts melatonin production, which in turn stimulates the ovaries to kick out extra estrogen — a known hormonal promoter of breast cancer.

In mood disorder research, interest in circadian rhythms is not new. For at least 50 years, investigators have questioned whether abnormalities in circadian rhythm regulation might be involved in the pathogenesis of mood disorders, including rapid-cycling bipolar disorder. These questions were motivated by three clinical observations. The first of these was that the sleep duration of patients often changes dramatically as they cycle between mania.i.mania; and depression, bipolar depression is typically associated with hypersomnia.i.hypersomnia; while mania is characterized by extreme and sometimes total insomnia.
The second observation was that approximately 60 percent of depressed patients experience remission after a night of total or partial sleep deprivation (SD). In bipolar.i.bipolar; patients, SD may actually cause a switch into hypomania or mania. However, this "upward" switch usually lasts only until the patient undergoes recovery sleep, leading to the formulation that SD, or extended wakefulness, is antidepressant, (or manicogenic), while sleep is depressogenic, (Wehr). The antidepressant effects of SD are conceptually important because they show that changes in sleep duration are more than just symptoms of the illness, and also play a pathogenic role.
