Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Scientific evidence refutes the idea that adult humans can biologically adapt to sustained sleep restriction, demonstrating instead that chronic sleep loss leads to cumulative cognitive deficits and physiological wear and tear.

The analysis

The retrieved literature consistently shows that humans do not biologically or cognitively adapt to chronic sleep restriction. Studies such as [1], [2], and [8] demonstrate persistent neurobehavioral deficits, unrecovered cognitive performance, and a lack of adaptation in sleep architecture over weeks of restricted sleep. Therefore, the claim is refuted.
