Patient discussion about lighting

Q. Is it true that is places with less sun light people tend to be more depressed?

A. that is correct- a good friend of mine moved to north Alaska about 3-4 years ago. in the winter they hardly have sun. then some of the people get depressed. the treatment is pretty funny- they have to move around with a hat with an illumination system shining over their eyes. they think that the lack of sun light causes a lack of certain chemicals in the brain.
