As a result, the scientists have already found that men move more during their sleep than women. With this approach the whole world becomes a sleep laboratory,” says Till Roenneberg. “Our new method makes it possible to collect objective information on the sleep characteristics and phases exhibited by individuals outside the usual laboratory setting, using a simple recording and analysis technique. The editors of Current Biology have hailed this new approach as a “breakthrough” in sleep research. However, while these sleep cycles of REM and non-REM sleep have so far been measured by means of electroencephalography in sleep laboratories, the pattern of LIDS can now be easily detected with wrist-worn monitors. These phases are associated with the onset and cessation of rapid (involuntary) eye movements (REMs) which occur several times every night. The study confirms that the alternation of bursts of movement and bouts of immobility essentially correspond to the known cycles of REM and non-REM (deep) sleep. The study’s authors called their measure “Locomotor Inactivity During Sleep” (LIDS). By focusing on phases of immobility and contrasting them with phases of movement during natural sleep, they were able to detect rhythms in movement that recurred at intervals of approximately 90 minutes. In the third phase of their long-term Human Sleep Project, the chronobiologists at LMU took advantage of this to study the dynamics of sleep phases in over 16,000 sleep bouts from 593 experimental subjects between the ages of 8 and 92. Instead it is characterized by phases of involuntary movement, which correspond to distinct physiological states. Sleep is not a resting state in which we remain immobile. Eva Winnebeck, who is in charge of its Sleep Laboratory. The technique is validated in a new paper published in the journal Current Biology, which reports work carried out under the direction of Professor Till Roenneberg, who heads the Human Chronobiology Group at the Institute of Medical Psychology at LMU, and Dr.
For a simple wrist-worn device now suffices to record the essential characteristics of natural sleep bouts. Thanks to the development of a new analytical technique, experimental subjects can sleep in their own beds while contributing to the scientific understanding of what remains a mysterious biological phenomenon.
