What is bright light therapy?
Sleep disorders and disruptive behaviour during the night are commonly associated with dementia. Bright lights have been found to be beneficial as a treatment for these sleep disturbances.
In bright light therapy, a person sits in front of a light box that provides about 30 times more light than the average office light, for a set amount of time each day.
