LED technology helps improve sleep and emotional problems in Alzheimer's patients.

An illuminating experiment was conducted at the Rensselaer Polytechnic Institute lighting research center in New York, USA. It was pointed out that patients with Alzheimer's disease in the sanatorium had the opportunity to improve sleep and emotional problems under the illumination of natural light sources.

Researchers conducted at least 43 weeks of experiments in 43 out of three states, 37 of which lasted longer than half a year. According to the habits of sanatorium patients, researchers will provide tables with LED lighting or provide single room lighting. Since lighting stimulates the secretion of melatonin in the brain, it regulates the body's work and rest. After the end of the experiment, more than half of the patients have improved their sleep disturbance and depressed mood.

According to statistics, a total of 5 million 700 thousand people in the United States suffer from Alzheimer's disease. In addition to thinking and remembering, patients also suffer from sleep disturbances, irritability, anxiety and confusion. Mariana Figuerio, head of the research team, said that one reason for Alzheimer's patients' lack of self-care ability was due to lack of sleep and behavior.

Figuerio believes that if people continue to be exposed to darker light, the quality of sleep will decline. To improve the symptoms of Alzheimer's disease, we can start with improving the quality of lighting. Figuerio also said that under the progress of LED technology, it is easier to control the color of light and light. Through light sources, the ratio of inhibition of melatonin to light sources increases during the day, and decreases at night, so that patients can regular day and night rest and rest.
