The so-called night mode of smartphones when the blue glow is blocked and yellow increases can be harmful, said Manchester scientists. Experts tested the effect of color radiation on the body using experiments on mice. As it turned out, the yellow spectrum, which is configured on the displays of smartphones in night mode, can adversely affect health. The fact is that bright warm colors mislead the biological clock of the body, as they are associated with daylight hours.

According to scientists, the muted blue color is more familiar to the body in the dark than weak yellow.

Researchers advised not to take the advice of smartphone manufacturers as the last truth and with great caution use the Night Shift and Dark Mode modes on iOS and Android, respectively.
