Lumie Arabica. None of us like the dark nights and dark mornings of winter, and most of us eat and sleep slightly more. This is known as the 'winter blues'. However, some people suffer to such an extent that it causes overeating, depression, complete lethargy and joint pain, amongst other things. This is known as SAD or Seasonal Affective Disorder. This is caused by the lack of bright light in winter - light helps regulate our daily rhythms and hormone production, and for some people, this lack of light can be a real and crippling problem during the winter months. To successfully treat SAD, light needs to be delivered at a minimum of 2500 lux (that's the technical term for how bright a light is) - but the Lumie Arabica has been proven to deliver 10,000 lux from a distance of 25cm. That means that your treatment will be more effective and the treatment time will be shorter. And buy this Lumie Arabica Now £118.99.

Valkee Bright Light Headset. The traditional way to treat the symptoms of SAD is lightbox therapy. However, the experts at Valkee have discovered an alternative. They have developed the first SAD light technology that works via the ear canal, through a small device that looks like an MP3 player, and shines the light into the ears via earbuds.
