Beijing: A study found that light-assisted sleep can improve sleep and reduce depression and aggressive behavior in dementia patients.
A study conducted at Weifeng Medical University in China found that exposure to bright light can help reset the body clock.
The study, published in the journal PLoS One, studied 15 trials conducted in seven different countries between 2005 and 2022. These trials looked at light therapy as a treatment for Alzheimer’s.
The participants in the study were patients with mild to moderate dementia and were aged between 60 and 85 years.
The study found that light therapy improved the quality of sleep of the study participants and they spent less time awake in bed. Whereas dim lighting had less beneficial effects on sleep quality.
Alzheimer’s patients have reduced sensitivity due to nerve damage and need more light.
In the study, after light therapy, dementia patients were found to be less aggressive and had a reduction in the severity of depressive symptoms.
Sleep problems affect 70 percent of people in the early stages of the disease.
