Sleep inversion or sleep-wake inversion is a reversal of sleeping tendencies. Individuals experiencing sleep-wake inversion exchange diurnal habits for nocturnal habits, meaning they are active at night and sleep during the day. Sleep-wake inversion, when involuntary, can be a sign of a serious disorder. [1]
A circadian rhythm is an entrainable, endogenous, biological activity that has a period of roughly twenty-four hours. This internal time-keeping mechanism is centralized in the suprachiasmatic nucleus (SCN) of humans, and allows for the internal physiological mechanisms underlying sleep and alertness to become synchronized to external environmental cues, like the light-dark cycle.

EDS can be a symptom of a number of factors and disorders. Specialists in sleep medicine are trained to diagnose them. Some are: Insufficient quality or quantity of night time sleep [5] Obstructive sleep apnea [6] Misalignments of the body's circadian pacemaker with the environment (e.g., jet lag, shift work, or other circadian rhythm sleep ...
Napping during the day may seem like a good way to make up for lost sleep, but it can lead to more variable sleep times and quality of sleep during the night, Espie says. “Sleeping during the ...
Treatment for irregular sleep–wake rhythm tries to enable the body clock in the brain, such that a normal long sleep period at night can be achieved. Education about sleep hygiene is important, and counseling can be helpful. Melatonin, vitamin B 12, sleep aids, wake aids, and other medications may also be used.
Disrupted sleep prevents the brain from suppressing bad memories. For this study, the researchers recruited 85 healthy adults ages 18–30 years — of whom 30 were male and the rest female ...
A reversal [clarification needed] in the sleep–wake cycle may be a sign or complication of uremia, [140] azotemia or acute kidney injury. [141] [142] Studies have also helped elucidate how light has a direct effect on human health through its influence on the circadian biology. [143]
In the short-term, not sleeping enough can negatively impact cognitive functioning the next day. "Even with one night of very little sleep in comparison to what your baseline might normally be, we ...
