Today, light therapy is becoming an extremely popular treatment for SAD or seasonal affective disorder, which is a kind of depression that affects people typically in the fall and dark and cold winter months. Research reveals that exposure to bright light from a light box or a special lamp can make up for the natural sunlight not available during these days and can help to alleviate the symptoms of SAD.

According to the NIMH (National Institute for Mental Health), light therapy lamps or sun lamps are usually much brighter compared to your regular lamp and deliver 10,000 lux light, which is around 20 times more than your standard indoor lighting. These lights are designed in a way to mimic outdoor light and exposure to the light for just around 20-60 minutes daily can help to ease the symptoms of SAD and enhance your mood greatly.

However, before buying a sun lamp, you must consider a few important factors. You must select a lamp that emits light of 10,000 lux intensity, which is ideal for the treatment of SAD and you must also ensure that the lamp filters out the UV rays, which can be damaging to your eyes. In our article, we will be discussing the 3 best sun lamps for the treatment of SAD.
