Watch Your Sleep, Watch Your Weight

Phototherapy -- or the regular use of concentrated bright light -- is a widely recognized treatment for the cyclical bouts of depression experienced by many who have seasonal affective disorder, or SAD. New evidence now shows that light therapy may benefit women who have both SAD and an… Continue

Built to Nap

Seventy-six percent of Americans are lacking something right now. No, it's not the latest fad fashion, electronic device or even money in the bank. It's sleep. Thomas Edison invented the light bulb so that people could work at night, and there are now 25 million night shift workers in U.S.-occupied territory. Thanks to the light bulb and the later invention of television, sleep quantity (per person) has decreased by about 20 percent since 1900. Furthermore, 76 percent of Americans… Continue

Alzheimer's Light Therapy Helmet

Trial participants will wear the helmet for 10 minutes a day

Treating Alzheimer's Patients with Light

Melinda LaGarce, an associate professor of interior design, conducted the research, a follow-up to a preliminary study she did with two other SIUC researchers. (Perspectives reported on that pilot work in spring 1997.)

The End of the Light Bulb as We Know It

From: U.S.News & World Report

By Marianne Lavelle

The incandescent light bulb, one of the most venerable inventions of its era but deemed too inefficient for our own, will be phased off the U.S. market beginning in 2012 under the new energy law just approved by Congress. Although this will reduce electricity costs and minimize new bulb purchases in every household in America, you may be feeli… Continue
