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.

Q. My husband has psoriasis and the dermatologist suggested that he try the uv light treatment.Anyone try it. some of the side effects may be skin cancer and melanoma's. If so can you please let me know if it actually did help or if not. Thanks a million.

A. uv light treatment procedure is relatively new mod of treatment so here is difficult to build an opinion about it.
Actually there are two main type of treatment relating uv light are in use one is uvb treatment and other one is PUVA (uva light based).

A. May sound a bit silly question, but have you tried to consult your ophthalmologist (eye doctor, e.g. the one that performed the operation) about it? Cataract surgery, although considered very successful, isn't problem-free. Primary physician may not have the necessary specialization to deal with these subjects.
