A couple of years ago I read on Seth Robert’s blog about the possibility that orange glasses might improve sleep. This week an article on the subject appeared in The New York Times.
“Studies have shown that such light, especially from the blue part of the spectrum, inhibits the body’s production of melatonin, a hormone that helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night.”
Unlike some media sources the Times provides links to the original research.
Might be worth trying.
