Boost Your Mood by Redecorating
"One of the keys to a home that elicits a lot of happiness and positive emotion is that it changes to some extent," says the University of Wisconsin's Richard J. Davidson, PhD. Even an environment that makes our spirits soar—an incredible view, for example—tends, over time, to grow stale. We get used to it. Davidson isn't suggesting turning your place upside down, but if you get the bug to move things around a bit or play with the lighting, you might find your own interior gets a lift toward the sunnier.
