Do SAD Light Therapy Boxes actually work?

The question of ‘Do SAD Light Therapy Boxes actually work?’ is often asked by both individuals who suffer from Seasonal Affective Disorder and Medical professionals alike.

A number of independent reviews, testing and studies have been undertaken for a number of years and continue to be investigated across the medical community worldwide.  This has been done to establish not only the best possible treatment for those who are affected by SAD, but also to see exactly how our eyes process the numerous wavelengths of light.  In turn the latter part will help in understanding how the body functions are affected in response to the light.

Opinions on SAD Light Therapy being effective are mixed and after collating and reviewing a great deal of research from the numerous studies conducted over the years, universally respected, global independent research network: Cochrane, concluded that due to a low quality of evidence, no definitive answer could be given as of yet.

Studies into the effects that light in the Blue light wavelength has on the eyes led to the discovery of a corresponding light-sensitive receptor that may be instrumental in maintaining the Circadian Rhythms of the body through regulation of the sympathetic nervous system and Melatonin levels.  This has led to the introduction of SAD Therapy Blue Light Boxes that are designed for quicker and more effective treatments with less intense light overall.

While a consensus is yet to be reached with definitive results, many Medical practitioners and those that suffer from Seasonal Affective Disorder have found that medically certified SAD Light Therapy Boxes and Lamps do have positive results in treating Seasonal Affective Disorder.  These have led to improved moods, regular sleeping patterns and more.

Before undertaking any light therapy for Seasonal Affective Disorder, ensure that you have spoken to a medical professional and have received a diagnosis for the condition along with light therapy treatments having been advised. provides general information only and should not be regarded as a substitute for medical advice from your own doctor or healthcare provider.
