The sleep–wake cycle and circadian rhythmicity both contribute to brain function, but whether this contribution differs between men and women and how it varies across cognitive domains and subjective dimensions has not been established.

We examined the circadian and sleep–wake-dependent regulation of cognition in 16 men and 18 women in a forced desynchrony protocol and quantified the separate contributions of circadian phase, prior sleep, and elapsed time awake on cognition and sleep.

Gli scavi archeologici di Ercolano hanno restituito i resti dell'antica città di Ercolano, seppellita sotto una coltre di ceneri, lapilli e fango durante l'eruzione del Vesuvio del 79, insieme a Pompei, Stabiae ed Oplonti.

Some circadian characteristics, such as the intrinsic frequency of the circadian clock and the amplitude of the melatonin rhythm, have been shown to differ between men and women.

Whether the circadian regulation of mental functions differs between men and women is unknown.

During anal sex, the partner inserting the penis is called the insertive partner (or top), and the partner receiving the penis is called the receptive partner (or bottom).

Receptive anal sex is much riskier for getting HIV.

The largest circadian effects were observed for reported sleepiness, mood, and reported effort; the effects on working memory and temporal processing were smaller.
