SAD is caused by a lack of light, and the best way to cure or prevent it is to increase your exposure to light. The most effective "treatment" is to get away during the winter to somewhere bright.

Given that most of us can't do this the next best option is to use light therapy, after all, if the problem is caused by lack of light from nature then it makes sense to get light by other means.

By using light therapy the underlying problem is removed. Light therapy can work for some people immediately for others it may take up to ten days or so.

I offer trials for a minimum fee. I also offer a range of lights to suit individual needs.
