Light at night (LAN) has been associated with negative health consequences and metabolic risk factors. Little is known about the prevalence of LAN in older adults in the U.S. and its association with cardiovascular disease (CVD) risk factors. We tested the hypothesis that LAN in older age is associated with higher prevalence of individual CVD …

SignificanceAmbient nighttime light exposure is implicated as a risk factor for adverse health outcomes, including cardiometabolic disease. However, the effects of nighttime light exposure during sleep on cardiometabolic outcomes and the related mechanisms are unclear. This laboratory study shows that, in healthy adults, one night of moderate (100 lx) light exposure during sleep increases nighttime …

Aims/hypothesisIn our modern society, artificial light is available around the clock and most people expose themselves to electrical light and light-emissive screens during the dark period of the natural light/dark cycle. Such suboptimal lighting conditions have been associated with adverse metabolic effects, and redesigning indoor lighting conditions to mimic the natural light/dark cycle more closely …
We present a pilot study of near-infrared (NIR) 1068 nm transcranial photobiomodulation therapy (PBM-T). Impact upon motor function, memory, and processing speed in healthy individuals, older than 45 years of age, was evaluated. Methods: PBM-T was performed at home using a transcranial phototherapy device, a helmet that comprised 14 air cooled light emitting diode panel arrays, …
