Of course now I need at least 6 hours sléep to feel ok all day, but sometimes I have less than that. Then I have days when I can crash for up to 10 hours, but not that often. Its like my body needs a recharge or my spírit wants to visit heaven for a while and can't do that when I am awake most of the time.... The myth of the eight-hour sléep[quote]We often worry about lying awake in the middle of the night - but it could be good for you. A growing body of evidence from both science and history suggests that the eight-hour sléep may be unnatural.In the early 1990s, psychiatrist Thomas Wehr conducted an experiment in which a group of people were plunged into dárkness for 14 hours every day for a month.It took some time for their sléep to regulate but by the fourth week the subjects had settled into a very distinct sléeping pattern. They slept first for four hours, then woke for one or two hours before falling into a second four-hour sléep.Though sléep scientists were impressed by the study, among the general public the idea that we must sléep for eight consecutive hours persists.In 2001, historian Roger Ekirch of Virginia Tech published a seminal paper, drawn from 16 years of research, revealing a wealth of historical evidence that humans used to sléep in two distinct chunks.His book At Day's Close: Night in Times Past, published four years later, unéarths more than 500 references to a segmented sléeping pattern - in diaries, court records, medical books and literature, from Homer's Ódyssey to an anthropological account of modern tribes in Nigeria.
