Here Comes the Sun

A number of studies have come out this year showing that sunlight exposure may reduce the risks of certain cancers.  In one study, researchers hypothesized that more sunlight exposure would increase the risk of non-Hodgkin lymphoma - instead they found out that sunlight exposure was correlated with a lower risk.

Why wouldn't sunlight be beneficial?  Humans have spent a large portion of their time in the sun for millions of years.  If anything, the current environment of being stuck in an office for most of the daylight hours would be a recipe for health problems.  No one is suggesting that people should burn themselves to a crisp, but regular, moderate sunlight exposure should certainly be part of a healthy lifestyle.
