How Does Lighting Affect Your Mood?

Doesn’t it seems like when we have warm, sunny days outside everyone is constantly announcing  that it’s beautiful outside – it has even become a great conversation starter, “Wonderful day isn’t it?”. On gloomy days it’s often quite the opposite. Comments such as “I’d rather be at home asleep” or “Look what this weather has done to my hair” become the norm.
