Blue
light may fight fatigue around the clock - Science Daily, 2/3/14 -
"Researchers compared the effects of blue light with
exposure to an equal amount of green light on alertness and performance in
16 study participants for 6.5 hours over a day ... participants exposed to
blue light consistently rated themselves as less sleepy, had quicker
reaction times and fewer lapses of attention during the performance tests
compared to those who were exposed to green light. They also showed changes
in brain activity patterns that indicated a more alert state"

lue light has a dark side - Harvard Health Publications, 5/12 -
"Blue wavelengths—which are beneficial during
daylight hours because they boost attention, reaction times, and
mood—seem to be the most disruptive at night. And the proliferation of
electronics with screens, as well as energy-efficient lighting, is
increasing our exposure to blue wavelengths, especially after sundown
... LED lights are more efficient than fluorescent lights, but they also
produce a fair amount of light in the blue spectrum ... Expose yourself
to lots of bright light during the day, which will boost your ability to
sleep at night, as well as your mood and alertness during daylight"

Room
light before bedtime may impact sleep quality, blood pressure and diabetes
risk
- Science Daily, 1/13/11 - "exposure to electrical
light between dusk and bedtime strongly suppresses melatonin levels and may
impact physiologic processes regulated by melatonin signaling, such as
sleepiness, thermoregulation, blood pressure and glucose homeostasis ...
researchers evaluated 116 healthy volunteers aged 18-30 years who were
exposed to room light or dim light in the eight hours preceding bedtime for
five consecutive days. An intravenous catheter was inserted into the
forearms of study participants for continuous collection of blood plasma
every 30-60 minutes for melatonin measurements. Results showed exposure to
room light before bedtime shortened melatonin duration by about 90 minutes
when compared to dim light exposure. Furthermore, exposure to room light
during the usual hours of sleep suppressed melatonin by greater than 50
percent" - See

testosterone levels in men ... Previous
studies have shown that bright light therapy of daily exposure to specially
designed, high-intensity light boxes can alleviate many symptoms of
depression, especially among people who suffer from seasonal affective
disorder (SAD) during winter months"
