In susceptible individuals, the lower levels of light also trigger cravings for carbohydrates and weight gain. If you have these symptoms, but only seasonally in the fall and winter, light therapy may help. Since it's not a drug, there are no side effects to worry about. Light therapy is also much less expensive since a one-time purchase should last for the season and many more. Many people without a formal diagnosis of SAD benefit from light therapy. All you have to do is read the product reviews to see how much people love their light boxes.
Using Light Therapy
Using the light at other times of the day can be helpful if you have a problem with the afternoon slump or falling asleep too early in the evening. I generally suggest you start with 45 minutes of light therapy daily for about a week and then you can decrease to about 30 minutes a day.
I was skeptical at first, I just wasn't sure if it would work, but Amazon has a great return policy so I gave it a try. I kept it and it keeps me sane every winter. Without it I become forgetful and when I forget things I get stressed and frustrated. Light therapy has been a huge help both to memory and energy level.
