Enviro-Med manufactures and distributes light boxes used to for SAD, sleep disorders, shift work and jet lag. Sherrie Baxter, the company founder, is a Seasonal Affective Disorder (SAD) sufferer and user of light therapy. Her knowledge and appreciation of light therapy is your guarantee of scientific integrity and consumer protection. A Note From the President: Twenty years ago, I was a research subject in one of the original studies showing light therapy successfully treating Seasonal Affective Disorder (SAD) or the winter blues. I feel fortunate to have learned about light therapy so early in the research of SAD. Light boxes made it possible for me to enjoy winter, and I have had 19 years of seasonal depression free northwest winters. Light therapy has effectively given me back 5 months out of each year. My desire is to make it possible for everyone to have access to effective light therapy by designing Bio-Lights to strict scientific standards and keeping them affordable. My hope is that the one month trial guarantee encourages you to try it for yourself and see if it will help you as much as it has me.
