Research in psychology suggests the commonly held belief that uninterrupted eight-hour sleep cycles are optimal may be inaccurate. Many individuals in Spain have adopted this pattern, yet often experience poor sleep quality despite the duration. Experts now propose that segmented sleep – a historically common pattern of sleep broken into two periods – may be more natural and restorative. This challenges the modern emphasis on consolidated sleep. The findings indicate that humans may be biologically predisposed to a biphasic sleep schedule. Further investigation is needed to fully understand the benefits and practical application of these alternative sleep patterns, but the research suggests prioritizing sleep *quality* over simply achieving a specific number of consecutive hours.
