As you may recall, Apple originally added the night shift feature to iOS 9.3. Enabling the night shift can eliminate the blue light on the iPhone and iPad displays, thereby warming the color on the screen. At the time, studies showed that blue light fatigued the eyes and triggered a 24-hour sleep-awakening cycle. When enabled, the "night shift" and the Android version (called "night light") turn the display light yellow.

We don't know how many of you have vowed to get a good night's sleep through night shifts or night lights, but a study by scientists at the University of Manchester (through Android) suggests that blue light may not disrupt sleep patterns, which was summarized in earlier studies. "the use of dim, cool, night lights and bright lights during the day may be more beneficial to our health," the report said, subverting old findings. To prove this, the researchers pointed out that dusk is darker and bluer than the sun, and the body's biological clock uses these two characteristics to determine when to wake up and when to fall asleep. Original research from 2015 to 2016 showed that using warm colors at night was more beneficial.

Eliminating yellow and blue light in the night shift is not good for your biological clock, according to a new study.

Scientists at the University of Manchester say night shifts and night lights may send mixed messages to the human body by restricting users' exposure to blue light. The researchers used mice with special lights that could change color but not brightness. They found that blue light had a weaker effect on the biological clock of mice than yellow light. Dr Tim Brown, of the research team, said: "We generally believe that blue light has the greatest effect on the clock, which is misleading; in fact, the blue associated with dusk is weaker than white or yellow light of the same brightness." .

If using night shifts or night lights makes it difficult for you to fall asleep at night, your answer is to confirm the findings of researchers at the University of Manchester. Dr Brown said: "our findings suggest that using dim and cool lights at night and bright and warm lights during the day may be more beneficial. Studies have shown that it may be better to keep the body clock in line with social and work schedules. For our health. The correct use of color may be a way to help us better achieve this goal."

Whether you use iOS or Android, you can try this theory tonight. Disable "night shift" or "night light" to see if you can sleep well.
