Hi All, I just thought I would pass on an idea. In the past, my son's mood changes have typically gotten worse as the summer approaches. Something about the increase in daylight causes his cycling to increase, and he becomes hypo manic for much of the summer. I can literally set my calendar by it, it is that profound. From the research I have done, this is not at all uncommon for those with bipolar, and the opposite is true for those with depression - the more daylight, the better they feel. For those with depression, often UV light therapy is prescribed as a way to alleviate some of the depression - so in this vein I decided last year to do the opposite for my son. Last spring I got a large blackish-blue sheet and put it over the already existing blinds in his room, thus making his room pitch black. He has a large picture window in his room, and it faces South, so there was a lot of light coming in. Of course it looked like a cave, and it bothered me a bit that it seemed so gloomy, but he loved it. Since he is a teenager. he is in his room a lot, therefore I did not close or blackout the blinds in the rest of the house, but just kept it focused to his room. I am hear to tell you - last summer was the first summer he has stayed (within reason) somewhat calm. I really am not sure if something as simple as this could have this profound of an effect - but I am not about to alter it. So, as summer approaches quickly here in Texas (it is 80 today), and daylight savings is earlier this year, I thought I would share this tidbit!
