Nathaniel Kleitman

Nathaniel Kleitman was an influential American scientist who pioneered the study of sleep and circadian rhythms. His research helped reveal how our internal biological clocks regulate sleep-wake cycles, affecting health and daily functioning. Kleitman’s work laid the foundation for understanding the importance of sleep patterns and led to discoveries about rapid eye movement (REM) sleep. His studies have also informed treatments for sleep disorders and improved overall knowledge of human physiology related to sleep and wakefulness. Kleitman’s contributions significantly advanced the scientific understanding of sleep's vital role in our well-being.
