BYU Study Suggests Night Shift Doesn’t Help People Sleep

Cami Buckley, writing for BYU News:

Until recently, claims of better sleep due to Night Shift have been theoretical. However, a new study from BYU published in Sleep Health challenges the premise made by phone manufacturers and found that the Night Shift functionality does not actually improve sleep.

To test the theory, BYU psychology professor Chad Jensen and researchers from the Cincinnati Children’s Hospital Medical Center compared the sleep outcomes of individuals in three categories: those who used their phone at night with the Night Shift function turned on, those who used their phone at night without Night Shift and those who did not use a smartphone before bed at all.

“In the whole sample, there were no differences across the three groups,” Jensen said. “Night Shift is not superior to using your phone without Night Shift or even using no phone at all.”

My theory all along has been that Night Shift just makes your screen look hideously mis-colored.
