Light therapy provides extra light during the winter months that can help your body adapt to the lack of sunlight thereby increasing your energy and mood. The one pictured here is about 6" x 6" and emits blue light while others emit white light. It can be adjusted for light intensity and has a built-in timer. Light boxes come in a variety of shapes and sizes. The directions come with each unit, and you can read more about them online. Click
