The majority of people (97%) cannot reduce their sleep time without consequences; only a very restricted group possesses genetic mutations allowing for 'biological compression' of sleep without impairment of vital functions.

Science strongly supports the existence of these 'short sleepers,' often linked to specific mutations such as those in the DEC2 or ADRB1 genes, confirmed by family studies and laboratory trials (meta-analyses and genetic studies published in journals like 'Science'). For the general population, the consensus is solid: chronic sleep deprivation leads to a measurable cognitive and metabolic decline, validated by numerous randomized controlled trials (RCT). The creator rightly points out that the illusion of well-being during sleep deprivation is a common cognitive bias. However, the term 'Sleep Architecture' used here is a classic concept in sleep research (describing REM/non-REM cycles) and not a new conceptual approach in itself. The idea is therefore scientifically grounded, although the use of the term here is more rhetorical than innovative.
