Seasonal Affective Disorder (SAD)

Over 11 million people in the U.S. are directly affected by a shortage of light.  As the seasons change and the days shorten, it becomes problematic for many adults who do not get enough exposure to light. Most people do not cascade into a depressive episode and can adjust to the shortage of light.  However, for some individuals the lengthening of night signals melatonin production in the brain, which has a slowing down effect on the body. Individuals who are affected by Seasonal Depression generally have a lift in mood in the spring when longer days signal the body to shut off melatonin production in the morning.  Melatonin affects our circadian rhythms which are our daily sleep and wake cycles.

Research indicates that blue and green light waves entering our photoreceptors of the eye are effective in lifting our mood.  In turn, our biological clocks are responsive to exposure to the blue light or full spectrum lighting helping to regulate our circadian rhythms.  Light therapy has proven results in treating SAD and may be considered as the first line of treatment to alleviate symptoms. An average 10,000 lux light is recommended for a minimum of one hour per day has helped an average of 65% of sufferers.  To read more on the subject, Google: Seasonal Depression and Full- Spectrum lighting. 

There are multiple products available to assist in increasing exposure to full spectrum lighting.  An example is to purchase the bulbs and replace the ones in your vanity and reading lamps in your home.  Many adults report the type of light is better for reading as it is brighter overall.  In addition, there are products on the market such as lamp boxes and light simulators which are available for purchase as well.  Please consult your primary physician prior to making a purchase of this type for your specific circumstances.
