Light Therapy Awarded A Noble Prize
Did you know that light treats disease?

Light therapy is a method used for the treatment of skin diseases such as psoriasis and atopic dermatitis, psychiatric disorders, and more comprehensively, anticancer therapy using the components of sunlight. Among these, light therapy for skin diseases has a very long history. From around 2000 BC, ancient Egypt and India have been treating skin diseases by applying plant extracts and sunshine.

In the 19th century, there was a great deal of research and interest in phototherapy. In particular, Niels Ryberg Finsen, a Danish doctor, was awarded the Nobel Prize in Physiology or Medicine in 1903 for his treatment of tuberculosis skin disease using solar light in a systematic and scientific way. In recent years, phototherapy has also been shown to reduce the inflammatory symptoms of many diseases by affecting the immune system.
