Reverse Chronotherapy
A modified chronotherapy is called controlled sleep deprivation with phase advance, SDPA. One stays awake one whole night and day, then goes to bed 90 minutes earlier than usual and maintains the new bedtime for a week. This process is repeated weekly until the desired bedtime is reached.
Sometimes, although extremely infrequently, "reverse" chronotherapy – i.e., gradual movements of bedtime and rising time earlier each day – has been used in treatment of patients with abnormally short circadian rhythms, in an attempt to move their bedtimes to later times of the day. Because circadian rhythms substantially shorter than 24 hours are extremely rare, this type of chronotherapy has remained largely experimental.

Famous quotes containing the word reverse:
“During the late war [the American Revolution] I had an infallible rule for deciding what [Great Britain] would do on every occasion. It was, to consider what they ought to do, and to take the reverse of that as what they would assuredly do, and I can say with truth that I was never deceived.”
—Thomas Jefferson (1743–1826)
