I've heard that reading from a novel daily, with a large continuous story, increases empathy. This effect is said to last for 5 days after the last reading session. Unfortunately I can't find the source, but I think that this is a helpful data point. With the moral of the story being that it's something to continuously keep up, to have the benefit.
