Blue light makes people alert at night
Live Science has a write-up on a study by Steven Lockley of the Brigham and Women's Hospital and Harvard Medical School that indicates that blue light makes people less drowsy in the middle of the night. The affect also was found to be long lasting - the study tested out to 6.5 hours without identifying the end of it. The research is reported in the February 1 issue of the journal Sleep.
