polyphasic

Elderly humans often have disturbed sleep, including polyphasic sleep.

A polyphasic sleep pattern he claims is the way da Vinci slept during his lifetime.

Polyphasic sleep is common in many animals, and is believed to be the ancestral sleep state.

The term polyphasic sleep is also used by an online community that experiments with alternative sleeping schedules to achieve more time awake each day.

The book covers over 50 topics, including rapid fat loss, increasing strength, boosting endurance and polyphasic sleep.

He experimented with polyphasic sleep, which he called Dymaxion sleep.

Dymaxion also came to describe a polyphasic sleep schedule he followed, consisting of four 30 minute naps throughout the day.

Kramer tries polyphasic sleep, also known as Da Vinci sleep.

The most commonly accepted definition is the polyphasic species definition, which takes into account both phenotypic and genetic differences.

The circadian rhythm disorder known as irregular sleep-wake syndrome is an example of polyphasic sleep in humans.

In response to questions from readers about the "uberman" schedule of "polyphasic sleeping", she commented as follows:

The two scientists attached a polyphasic grappler to unlatch the metal clamp holding the topmost panel in position.

A contemporary fad called polyphasic sleeping entails avoiding long sleeps, instead taking regularly spaced short naps.

On the basis of this polyphasic study, it is proposed that these isolates represent a novel species, Mycobacterium pseudoshottsii sp.

People also use voluntary sleep deprivation to help them convert from monophasic sleep to polyphasic sleep.

In schedules involving night shifts and fragmentation of duty periods through the entire day, a sort of polyphasic sleeping schedule was studied.

Mr. Rosengarten, playing a tweed-bound professor, embarks on an intentionally boring lecture about the "polyphasic nature" of coffee.

"The Friar's Club" - Kramer's experiment with polyphasic sleep causes him to fall asleep during a make-out session.

People have tried to adopt a polyphasic schedule of naps totalling about two to six hours per day, in order to gain more time awake in their day.

Critics of polyphasic sleep dispute the notion that the human brain can simply be classically conditioned to tolerate a state of near constant wakefulness without deleterious effects.

For example, the excitation can be oscillatory ("polyphasic") or not (approximately "monophasic," with a sharp upgoing excursion followed by a weaker, but longer negative going excursion).

In August 2006, he agreed to take part in a polyphasic sleep experiment presented on BBC One's The One Show programme.

An example of polyphasic sleep is found in patients with irregular sleep-wake syndrome, a circadian rhythm sleep disorder which usually is caused by head injury or dementia.
