Seasonal affective disorder light boxes

by admin

Seasonal affective disorder can be treated in a number of ways. Many opt for prescription drugs or psychotherapy for relief, but others that are plagued with the affliction seek a more natural method of treatment in light therapy. Light therapy for seasonal affective disorder is generally done in the home under no direct physician supervision. The patient sits or stands in the direct path of a bright light emitted from a light box that houses powerful fluorescent light bulbs. The light given off from the light box is so powerful and close to natural sunlight that it helps the seasonal affective disorder sufferer’s brain release natural chemicals such as melatonin that will elevate mood and overcome the depressive symptoms of SAD.

As you may expect, there are several models of light boxes available that are specifically manufactured for the treatment of seasonal affective disorder. While price may be a main factor in the search there are other factors that must be considered:

  • Ultraviolet light exposure – Look for light boxes that either shield emitted UV rays or simply do not expose the user to UV rays.
  • Blue light exposure – Blue light exists at the far end of the light spectrum and should be avoided as much as possible due to its unwanted affects on the eyes and eyesight.
  • Light intensity – Optimum intensity is usually around 10,000 lux. Look for a light box that can deliver this recommended dosage at more than just a couple of inches so that you can remain comfortable while using the light box.
  • Size – Be sure to buy a light box that is the appropriate size to the area in which you will be using it.
  • Light direction – Light therapy boxes should broadcast the light from above the eyes and from no other direction, thoroughly mimicking the direction of the sun

Light boxes for the treatment of seasonal affective disorder can typically be purchased over-the-counter without a prescription from a doctor. While they may be easier to find online, finding several in a store will give the SAD sufferer the opportunity to more closely inspect the light box to ensure that it may suit their needs.

Persons with SAD should consult their physician before starting a light therapy regimen. Some possible side effects include irritability, fatigue, eyestrain, headaches, insomnia, dry mouth, agitation, and nausea. Side effects typically subside quickly after discontinuation of the treatment.
