Q&A: Light and Vitamin D for Seasonal Insomnia

Some people have trouble sleeping when the days get shorter. I’m one of them and so is Gabriel, who recently wrote in wondering how to improve his sleep:

“I was born close to the equator in Brazil, and I usually don’t have problems sleeping when I’m there or during the summer time in Canada, where I live now. But winter is around the corner, and my sleeping problems have just begun again. I usually go to bed at 11 p.m. but wake up around 3 a.m. However, in the summer my wake time is 7 a.m. I feel irritated, depressed and cannot concentrate. . . Is light treatment the way to go?”
