Blue Light: Best At Night
Over at LiveScience.com they say blue light helps fend off drowsiness in the middle of the night and makes people alert at night. This insight came from a small study of 16 volunteers found that exposure to blue light perked them up.
“Light exposure to this system, particularly blue light, directly reduces sleepiness,â€ said Steven Lockley of the Brigham and Women’s Hospital. â€œSubjects exposed to blue light were able to sustain a high level of alertness during the night when people usually feel most sleepy, and these results suggest that light may be a powerful countermeasure for the negative effects of fatigue for people who work at night.”
I wonder if the blue light from my clock radio keeps me up at night. Or if the amber lighting from my vehicle makes me sleepy. Maybe I should switch the two.
