Play mobile phone at night with night mode? Study: May be harmful to biological clocks

, Dec. 20 (Xinhua) -- Scientists at the University of Manchester in the United Kingdom have explained that the night pattern of blue light radiation used by smartphones has a negative effect on the body's day and night patterns.
, the researchers decided to test this hypothesis, and when converted to dark mode, the yellow spectrum on the phone's screen could be harmful to the biological clock.
team tested laboratory mice that showed that the warm color of the night mode was like daytime light and would awaken the body. This light has a bad effect on sleep and does more harm than good.
, the cold light of the blue spectrum, which is characteristic of the common pattern of gadgets, makes the body more accustomed. Scientists believe that in this case, there will not be too many negative effects on sleep.
, according to Jim M. "In fact, blue light associated with twilight is less effective than white or yellow light, " Brown said. He
: "Research has shown that keeping our biological clocks in line with daytime patterns and work schedules can be good for your health. Proper use of colors may be helpful in this regard. ”
