Exposure to extraordinarily brief, millisecond flashes of bright light improves alertness at night.
Results indicate that subjective sleepiness decreased and objective nighttime alertness improved after participants received a two-millisecond pulse of bright light once per minute for 60 minutes.
Cephalon announced that Mayo Clinic Proceedings published data from a Phase III trial of Nuvigil (armodafinil) Tablets [C-IV] demonstrating it significantly improved wakefulness throughout the shift in patients with excessive sleepiness associated with shift work disorder.
A study published in the December 1, 2008 issue of the journal Sleep shows the use of light exposure therapy, dark sunglasses, and a strict sleep schedule can help night-shift workers create a “compromise circadian phase position” which may result in increased performance and alertness during night shifts, yet still allow for adequate nighttime sleep on days off.
Results from the study show the performance was better for the experimental subjects than the control subjects. When the phase delays of the experimental group had likely reached the compromise circadian position, performance for this group was close to the level during day shifts, demonstrating fast reaction times with low variability and few or no lapses.

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
