A night shift worker with poor daytime sleep may be awake for more than 18 hours by the end of his shift. The effects of acute sleep deprivation can be compared to impairment due to alcohol intoxication, [ 9 ] with 19 hours of wakefulness corresponding to a BAC of 0.05%, and 24 hours of wakefulness corresponding to a BAC of 0.10%.
In a study done with around 1100 nurses, almost half of them (49%) reported sleeping less than 7 hours per day, a significant increase compared to national figures, in which 28% of people claimed to sleep less than 7 hours per night. [11] Having a lack of sleep can impact cognitive performance. [1]
The "first shift" often runs from 06:00 to 14:00, "second shift" or "swing shift" from 14:00 to 22:00 and a "third shift" or "night shift" from 22:00 to 06:00, but shifts may also have different length to accommodate for workload, e.g. 7, 8 and 9 or 6, 8 and 10 hours.
Health impact of only sleeping 5 hours a night After sleeping five hours in one night, most people can catch up with one or two nights of sleeping their normal amount or a few hours extra, says Kolla.
According to a study of 4,510 obstetric-gynecologic residents, 71.3% reported sleeping less than 3 hours while on night call. [4] In a survey of 3,604 first- and second-year residents, 20% reported sleeping an average of 5 hours or less per night, and 66% averaged 6 hours or less per night. [5]
The literature usually refers to a "one- to two-hour" delay per 24-hour day (i.e. a 25- to 26-hour cycle). [ citation needed ] Uchiyama et al. had earlier determined that sighted non-24 patients' minimum core body temperature occurs much earlier in the sleep episode than the normal two hours before awakening.
The naps would not be placed equiphasically, instead occurring more densely during night hours. [28] The U.S. military has studied fatigue countermeasures. An Air Force report states: Each individual nap should be long enough to provide at least 45 continuous minutes of sleep, although longer naps (2 hours) are better.
