We all feel better under natural daylight - more energetic, more awake, even more joyful. Research has shown that this is in part due to our brains releasing serotonin, a brain chemical that helps regulate mood, when exposed Sunlight. Sunlight can be hard to come by during the winter months which can bring about Seasonal Affective Disorder (SAD) or the Winter Blues. Light therapy has been shown to help alleviate SAD - enhancing mood, elevating energy and even improving sleep quality. The OttLite Clear Sun LED Light Therapy Lamp is like no other because of the proprietary Clear Sun LEDs that come as close to the spectral output of the Sun as you can get. Now you can have the rejuvenating power of natural daylight all year long. This discreet design is great for home, dorm, and office. With 3 brightness levels up to 10,000 lux, the device can be used horizontally or vertically with the included stand.
