As a species, humans are energetic, clever beings. We have risen above all other creatures because of our ingenuity and our ability to think things through. To find solutions to our problems and create tools to help us with things we need to do. Our ingenuity and inventive nature has helped us overcome handicaps and diseases. As time and technology has gone on, we have discovered the causes of many of the different afflictions our race deals with.
This is the case with SAD or Seasonal Afflictive Disorder. We have found that people suffering from this are not people suffering from a depression only treatable by drugs, they are people specifically affected by the lack of sunlight during winter months, or any time where there are days that are overcast, rainy or in any other way darkened.
We have now found that we can interrupt this cycle of sadness with brightness. This brightness comes from full spectrum lighting that is meant to imitate the effects of sunlight on the human body, allowing such things as the metabolizing of vitamins. With this full spectrum lighting, a SAD sufferer can look forward to a day of brightness, and a real, genuine good outlook on life, rather than one created by ingesting artificial mood enhancers such as the drugs that were previously prescribed for this condition.
