Do you use Apple’s Night Shift or other blue light filter apps while scrolling on your phone at night? If your answer to this question is yes, a new study from Brigham Young University has some news for you. According to the study, Night Shift is said to have no positive impact on your sleep quality.
In this study, BYU psychology professor Chad Jensen and researchers from the Cincinnati Children’s Hospital Medical Center compared the sleep results of 167 adults aged 18 to 24. The participants spent at least eight hours in bed and wore an accelerometer on their wrists to record sleep activity. They conducted the study in three categories – phone users with Night Shift, without NightShift, and those who didn’t use the phone before bed.
“While there is a lot of evidence suggesting that blue light increases alertness and makes it more difficult to fall asleep, it is important to think about what portion of that stimulation is light emission versus other cognitive and psychological stimulations,” Jensen added.
