Lamp doesn't act as a light source?

Darkness drains sanity. Light does not regain it. Making progress is the only way to regain it, at least according to the developers.

It'd be lame if you could just chill out by a light for a few minutes and be in tip-top shape.

I've found that relaxing next to a nice candlelight does increase sanity. I've gone from terrified and shaking hands to just having a slight headache by doing this and not making any progress. Though, I don't believe you can get to crystal clear.
