Academics from the Lighting Research Center at the Rensselaer Polytechnic Institute conducted a study that sought to determine the effects of blue, shortwave light on the sleeping patterns of seniors with Alzheimer's disease. The impetus for the research is the tendency for Alzheimer's patients to wake up frequently during the night. Such an irregular sleep pattern takes a heavy toll on the seniors' well-being and on that of the senior caretakers responsible for them. The center's research built off that of previous studies that showed how increased light exposure during the daytime could adjust the circadian rhythms of seniors with dementia.
