Healthy Light for a Healthy Brain Researchers at Mount Sinai’s Light Health Research Center (LHRC) are constantly developing new devices for delivering patients healthy doses of light. Here are a pair of blue-light goggles designed to improve sleep. As part of an NIH-funded project, LHRC will develop and test out whether a new sleep- and cognition-boosting device will help combat the debilitating effects of Alzheimer’s disease.
