About
Light therapy is a way to treat seasonal affective disorder, depression and certain other conditions by exposure to bright artificial light. During light therapy, you sit or work near a device called a light therapy box. The light therapy box gives off bright light that mimics natural outdoor light.
With seasonal affective disorder, fall’s short days and long nights may trigger feelings of depression, lethargy, fatigue and other problems. Don’t brush this off as simply a case of the “winter blues” that you have to tough out on your own.
Seasonal affective disorder is a type of depression, and it can severely impair your daily life. That said, treatment — which may include light box therapy — can help you successfully manage seasonal affective disorder. You don’t have to dread the dawning of each fall or winter.
Exposure to bright light from a light therapy box is thought to alter your circadian rhythms and suppress your body’s natural release of melatonin. Together, these cause biochemical changes in your brain that help reduce or control symptoms of seasonal affective disorder and other conditions. Light therapy is also known as bright light therapy or phototherapy.
