“…These results show that sleep is important and has very real consequences besides just being tired during the day. At the individual level, research has shown that sleep loss affects cognitive functioning, decision making, performance, memory/learning, and general daytime sleepiness (Belenky et al, 2003;Caldwell & LeDuc, 1998;Harrison & Horne, 1999;Heuer & Klein, 2003;Philip et al, 2005;Pilcher & Huffcut, 1996;Wyatt & Bootzin, 1994). As an example, one study showed that just one night of sleep deprivation tended to decrease cognitive performance by 30 to 40 percent, whereas two nights of sleep deprivation resulted in 60 to 70 percent decline in performance (Buguet, Moroz, & Radomski, 2003).…”
