1. Let in the Light
Exposure to as much sun as possible helps. Keep your curtains open all day, and rearrange your furniture so you’re regularly in bright places in your home. Install skylights if you can. Also, while artificial light isn’t as good as the real thing, adding more lamps to dark areas in your home is better than nothing. If you can afford it, head to the lands of minimal SAD near the equator. A sunny vacation will offer a welcome, if temporary, respite from the winter blues.
