This is the notion that animals need a more or less constant amount of sleep every day, so that if a subject is deprived of sleep one day, the amount of sleep tends to "rebound" (increase) the next few days. This has been observed in zebrafish. At night ...
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...

Getting a good night's sleep can be a little more challenging amid the hype of the holidays. With changes in routine, diet and potentially time zones, quality sleep could be difficult to come by ...
Gardner's sleep recovery was observed by sleep researchers who noted changes in sleep structure during post-deprivation recovery. [10] [11] After completing his record, Gardner slept for 14 hours and 46 minutes, awoke naturally around 8:40 p.m., and stayed awake until about 7:30 p.m. the next day, when he slept an additional ten and a half hours.
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
