took the excerpt below from CNN's article on Sleep Problems at http://www.cnn.com/2009/HEALTH/09/25/nine.sleep.problems/index.html -- what's interesting is that this is the first time I've seen a nationally recognized media outlet speak up about blue light, and how to block it. Have been stocking blue light blockers at ApneaLife.com for awhile now -- took liberty of adding the reference to ApneaLife to the reference mentioned in the article below:

Expert advice: To start slowing down and readying herself for an earlier bedtime, psychologist Rubin Naiman suggests blocking blue light. "The blue end of the light spectrum -- emitted by ordinary lightbulbs, televisions, and computer screens -- suppresses melatonin," says Naiman. Nicole might consider buying special lightbulbs as well as blue-blocker filters (available at http://www.apnealife.com and lowbluelights.com) for her TV and computer screen (if she insists on checking her e-mail) and reducing the amount of light in general. "Being exposed to too much light at night is the environmental equivalent of caffeine," says Naiman. So at least two hours before bed, dim the lights. In addition, Nicole needs to find time earlier in the day for catching up on e-mail and organizing.
