If you feel permanently tired and lacking in energy, the artificial lighting could be to blame. And it could be solved with a week of camping in the open air, according to a study carried out by Kenneth Wright, of the University of Colorado (USA), and published by the journal Current Biology.
After being up all night, men tend to overestimate the female "cues" they detect and think that women want to have sex with them even when they are not at all interested. On the contrary, women are not affected by having little rest when it comes to knowing if someone is trying to flirt with them.

Until now, scientists were unable to explain why insomnia and lack of sleep sometimes make us irritable. Recently, Pierre Maquet, from the University of...
Is it true that sleepwalkers forget everything they do? And that their movements are automatic? Does the habit of getting out of bed many nights - in more than 20% of cases, every night - have any repercussions? In a work published by the Lancet Neurology, researcher Antonio Zadra, from the University of Montreal (Canada), reveals that sleepwalkers do not always forget what happened while sleepwalking. Moreover, the author publishes that sleepwalking adults often remember what happened while walking in their dreams, including what they thought and what they felt during those night walks. Children and adolescents, however, having more immature brains, tend to suffer more episodes of amnesia when they are victims of this sleep disorder.
Are you one of those people who finds it especially difficult to get out of bed each morning when the alarm clock rings? Sleep medicine experts from the University of Flinders (Australia) have investigated the role of the biological clock in the tendency of night owls to go to bed late and the difficulty of getting up for work. The first findings indicate that when we suffer from the so-called delayed sleep phase syndrome, our circadian rhythm works slower than usual and allows us to stay awake and active for longer.
When muscular contractions not repressible by voluntary control appear at the moment of entering sleep, which are characterized by being brief, rapid and unexpected, and which sometimes affect the whole body and produce a sensation of falling into emptiness or stumbling, we speak of myoclonus of numbness.
