As humans spend increasing amounts of time indoors, we lose access to the sun’s natural benefits. Recognition of season affective disorder has grown accordingly. While the actual occurrence of the condition is low (around 5% — or 10 million or so Americans),  it’s led to increasing awareness of the sun’s impact on the production of serotonin in the brain – and its resulting impact on the human body.

Light therapy lamps have become increasingly popular as a result. I bought one a while back. It’s big, unwieldy and beams bright light like a tanning lamp. These products rely on the visible light spectrum, in a bid to mimic the sun’s impact for those of us who spend more of our waking hours in front of a computer than we care to mention.
