Exposure to bright outdoor light at night may increase the risk of developing Alzheimer’s disease, a study has found.
According to an American study reported by the New York Post (NYT) on the 16th (local time), there is a correlation between the prevalence of Alzheimer’s disease and exposure to light at night.
This correlation is particularly pronounced in those under 65 years of age.
The research team analyzed maps of light pollution, including streetlights, road lights, and signs, and divided the lower 48 U.S. states into five groups based on nighttime light intensity.
Research has shown that exposure to artificial light can disrupt the body’s 24-hour circadian rhythm and disrupt sleep, which can lead to cognitive decline.
In the case of the elderly, diabetes, high blood pressure, and stroke were found to increase the prevalence of Alzheimer’s disease. In particular, among those under 65 years of age, the higher the intensity of light at night, the stronger the correlation with Alzheimer’s disease.
The researchers aren’t sure why young people are more sensitive to light at night, but they speculate it may be due to their lifestyles that involve frequent exposure to outside light.
He then recommended using blackout curtains or sleep masks to block out harmful light.
She added that using blue light filters, using warm-colored light bulbs, and installing dimmers in the home are recommended.
