People who get fewer than eight hours of sleep per night show pronounced cognitive and physiological deficits, including memory impairments, a reduced ability to make decisions and dramatic lapses in attention... two weeks of limited sleep — about four hours per night — created brain deficits just as severe as those seen in people who hadn't slept at all for three nights. As sleep deprivation continues over time, attention, memory and other cognitive functions suffer. APAWhen attention suffers, everything goes south.
