Background information: I recently had a discussion with my friend about a disagreement when renting an apartment and whether or not he should rent a house that faces the sun. My friend has a diagnosis of depression, and he was concerned that a room facing west would cause him to not receive enough sunlight and back aggravate his condition.
Question: I do understand that there is a link between sunlight and depression, but I'm more interested in knowing exactly what factors affect depression and if they exacerbate it.
- Light intensity
- Duration of sunlight
