Light therapy – therapy based on shining bright white or coloured light onto a patient – has a history stretching back thousands of years to the Indians and ancient Egyptians. In modern times it’s used to treat eczema, acne, psoriasis, SAD syndrome (seasonal affective disorder) and winter depression.
At the ultraviolet end of the spectrum, PUVA treatment combines UV light with an orally taken drug to treat psoriasis, by utilising the UV light’s ability to suppress the immune system. PUVA is also used to treat certain cancers. Similarly, the antibacterial effects of ultraviolet light are sometimes used as an acne treatment – though skin damage can result from prolonged use. Visible violet light activates porphy rin, which damages and kills bacteria. Usually created by powerful LEDs, studies show effective acne reduction.
Red light appears to energise cells, and a NASA-sponsored study found links between red light treatment and increased healing of wounds and ulcers. But the most common use of light therapy is in the treatment of seasonal affective disorders. Winter depression happens because a lack of light leads to a chemical imbalance in the body. Bright white light from a light box, similar to daylight, can alleviate its symptoms and restore health and vitality.
Today there is research into low level laser therapy (LLLT) – shining focused light of certain wavelengths onto particular body points to alleviate pain, arthritis, and to heal wounds. Light therapy is a versatile, dynamic approach combining ancient wisdom with solid modern scientific advances.
