Study: Using Apple's Night Shift To Improve Your Sleep? Don't Bother

Researchers at Brigham Young University conducted a study to see how much blue-light-reducing features like Apple's Night Shift improve sleep quality. Their conclusion? Night Shift doesn't help at all. From a report: In the study, which was published in Sleep Health, the BYU researchers assessed the sleep quality of 167 young adults, asking each to wear a wrist accelerometer before sleep. Participants were randomly assigned three conditions regarding iPhone use before bed: one group didn't use their iPhones at all, one group used their iPhones without Night Shift enabled, and another group used their iPhones with Night Shift enabled. 'There were no significant differences in sleep outcomes across the three experimental groups,' the researchers concluded. For individuals who slept more than 6.8 hours per night, there was some improvement in sleep quality for those who did not use their smartphones at all. But Night Shift didn't have a significant impact, and there was no difference between those who used smartphones and those who didn't when the amount of sleep was less than 6.8 hours per night. 'This suggests that when you are super tired, you fall asleep no matter what you did just before bed... the sleep pressure is so high, there is really no effect of what happens before bedtime,' said Chad Jensen, one of the researchers.
