Do you use Apple’s Night Shift or other blue light filter apps at night when scrolling through your phone? 

If you answered yes, a new study from Brigham Young University has some good news for you. Night Shift is said to have no positive effect on your sleep quality, according to the survey.

The Effect of Night Shift on Sleep Quality

BYU psychology professor Chad Jensen and researchers from Cincinnati Children’s Hospital Medical Center compared the sleep patterns of 167 adults aged 18 to 24 in this study. 

The participants slept for at least eight hours and wore an accelerometer around their wrists to track their sleep activity. They divided the participants into three groups: those who used the phone with Night Shift. Those who did not use the phone before bed and those who did not use the phone at all.

“There were no differences between the three groups in the entire sample. “Night Shift is not superior to using your phone without Night Shift or even not using your phone at all,” Jensen stated.

The study considered various factors, including total sleep duration, sleep quality, wake after sleep onset, and time to fall asleep. The categories were further subdivided into two groups, one with seven hours of sleep and the other with participants getting six hours.

From the first set of data, the researchers discovered that participants who did not use their phones at night had better sleep quality than those who did, regardless of whether they turned on Night Shift. Furthermore, there were no differences in sleep outcomes depending on whether or not used Night Shift mode in the group that slept for 6 hours.

“While there is a lot of evidence that blue light increases alertness and makes falling asleep more difficult, it is important to consider what portion of that stimulation is light emission versus other cognitive and psychological stimulations,” Jensen added.
