Contextual System: Sleep Debt and Deprivation

The idea of slept debt asserts that ones record of sleep is like a bank account; that when missing sleep, you never get a "clean slate" and that every missed hour hangs around affecting your mental and physical health, until you repay it. As a country we are sleeping significantly less than we did a century ago, and some believe this has lead to a widespread loss of creativity. The effects of sleep debt are slow to manifest, but can lead to a myriad of health problems as serious as heart disease, or heart attack. To repay, one doesn't need to go on a "sleep marathon", and this is unlikely to work anyway. Most doctors and experts agree that the debt can be paid by maintaining a consistent, and if possible natural, waking time, and simply going to bed earlier every once in awhile. After a few of these sleep boosts, it is best to maintain a consistent sleep to wake schedule to be healthy.

Although there is some skepticism as to the validity of this idea of sleep debt, there seems to at least be a consensus on REM debt. Not everyone needs eight hours of sleep a night, but they do need some amount of REM sleep. Studies where subjects were deprived REM showed that the body would attempt to make up the lost REM sleep on it's own by increasing the time spent in REM. And when constantly denied REM, hallucinations and a loss of touch with reality begin to occur.
