If you haven't tried Night Shift on your iPhone, you can easily try it out by opening your Control Center, pressing and holding the brightness control icon, and then toggling the Night Shift icon on/off. And for some people, that's more than enough.
Sleepiness scores were low overall (3 on a 1-9 scale, with higher score indicating greater sleepiness), with 45 of nurses having high level of sleepiness (score > 7) on at least one shift. That said, there's no doubt that the effect, which gives your screen a orangish hue, makes it feel easier on the eyes. Sleep was short (mean 5.5 h) between shifts, with little difference between day shift (5.7 h) and night shift (5.4 h). The conclusions by the BYU study might be frustrating for those who have been using Night Sight (or a feature like it) for years.
This, of course, is very different from what other studies have been saying for years - which has been that looking at the blue light (created from our smartphones and computers) at night can make it more difficult to fall asleep and it can negatively effect the quality of your sleep, too. Yet, according to the study, "there were no significant differences in sleep outcomes across the three experimental groups." It works with older Macs, and even Macs running older operating systems, like El Capitan and Yosemite. It's been a great tool for years on the Mac and might just have been the inspiration for Night Shift. One group used their iPhone for the hour before going to bed with Night Shift turned on one group did the same thing with Night Shift turned off and the last group didn't look at their iPhone at all. f.lux is an app that offers Night Shift-style brightness and hue adjustments depending on the time of day. The study took a group of 167 people (between the ages of 18 and 24) and divided them into three groups. Certain nurses appear more vulnerable to sleep loss than others, as measured by attention lapses.A new Brigham Young University study published in Sleep Health has concluded that, as it relates to a person's quality of your sleep, Night Shift has no real effect. Nurses accrue a considerable sleep debt while working successive 12-h shifts with accompanying fatigue and sleepiness. It has gained around 5000000 installs so far, with an average rating of 4.

Lapsing was traitlike, with rare (39% of sample), moderate (53%), and frequent (8%) lapsers. Asylum Night Shift - Five Nights Survival is an Android Action app developed by Digi-Chain Games and published on the Google play store. There were no statistically significant differences in mean reaction time between day/night shift, consecutive work shift, and time into shift. Fatigue was high in one-third of nurses, with intershift fatigue (not feeling recovered from previous shift at the start of the next shift) being most prominent. There was extensive caffeine use, presumably to preserve or improve alertness. Nurses were progressively sleepier each shift, and night nurses were sleepier toward the end of the shift compared to the beginning. Sleepiness scores were low overall (3 on a 1-9 scale, with higher score indicating greater sleepiness), with 45% of nurses having high level of sleepiness (score > 7) on at least one shift. Sleep was short (mean 5.5 h) between shifts, with little difference between day shift (5.7 h) and night shift (5.4 h). Occupational fatigue (Occupational Fatigue Exhaustion Recovery Scale ) was assessed at baseline. Sleep (actigraphy), sleepiness (Karolinska Sleepiness Scale ), and vigilance (Performance Vigilance Task ), were measured serially in 80 registered nurses (RNs). This study describes sleep, sleepiness, fatigue, and neurobehavioral performance over three consecutive 12-h (day and night) shifts for hospital registered nurses. Objectively measured sleep times have not been often reported. Nurses working 12-h shifts complain of fatigue and insufficient/poor-quality sleep.
