Phototherapy, Light and Health – All Posts
Increasingly the health benefits of light are being appreciated and verified in the scientific literature. Whilst many people know that ultraviolet produces vitamin D in the skin, few realise that for much of the day and most of the year the sunlight contains too little UVB to make vitamin D. Recent research shows that ultraviolet light also releases nitric oxide and reduces blood pressure. The harmful effects of ultraviolet light are mitigated by certain foods that protect the skin. Finally, visible light, and especially red light is proving to have remarkable healing effects on the skin, hair, muscles, brain and eyes.
