And a group of collaborators from several other organizations have discovered that blue light helps to suppress human sleepiness during the night, if he is forced to stay awake and stay focused attention. The work was published on 1 February in the journal Sleep .
A small study of 16 volunteers showed that the blue lights "raised" them, helping you to remain active at night and banishing lethargy. In contrast to the situation where a light was not.
The authors suggest that blue light can help in cases where a person is forced to work at night, or, say, drive a car. But here it is necessary to put more experiments. In addition, doctors warn, in large doses, blue light can damage eyes.
The new finding is consistent with other studies that reveal the relationship of the cycles of wakefulness and sleep, and with the progress of the biological clock.
