The following videos are parts one and two (of two) from a public lecture given by Dr. Raymond Lam at a conference of the Society for Light Treatment and Biological Rhythms.
Dr. Lam describes Seasonal Affective Disorder (SAD) and the less severe mild seasonal depression sometimes called the “winter blahs”. He goes on to explain the basics of using light therapy to combat SAD and the winter blahs. Light therapy is remarkably effective, and works better than anti-depressant medications for many people – and does not have the dangerous side-effects that are sometimes associated with the medications.
