You need natural light to start your day on a high note. Set aside some 30-40 minutes to be out in the open when the sun is out. “It definitely helps - a morning walk gives you a daylight boost as well as some exercise,” Scott-Thompson, who experiences SAD, as does every member of the organization, says. If you can’t, walk outside it in the early afternoons and the day is usually brightest. Sit next to a window when you you’re inside.
