This method is used for the ultraviolet (UV) blood irradiation (UVBI) by UV lamps. In the transcutaneous method, the radiation goes through the skin, by placing a device on the outside of the skin. In the intravenous method, a device is inserted into a large blood vessel. The laser light is monochromatic.
From an antique Master Violet Ray manual c. 1920 comes this treatment advice: Brain Fog - Use Applicator No. I over forehead and eyes. Also treat the back of head and neck with strong current in direct contact with the skin. Treat the spine and hold the electrode in the hand. Ozone inhalations for about four minutes are also of importance.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
PUVA (psoralen and UVA) is an ultraviolet light therapy treatment for skin diseases: vitiligo, eczema, psoriasis, graft-versus-host disease, mycosis fungoides, large plaque parapsoriasis, and cutaneous T-cell lymphoma, using the sensitizing effects of the drug psoralen.
Tanning beds are used both in dermatology practices for the treatment of cosmetic skin conditions (such as psoriasis, acne, eczema and vitiligo) and in indoor tanning salons for cosmetic tanning. Typical treatment regimens involve short exposure to UVB rays 3 to 5 times a week at a hospital or clinic, and repeated sessions may be required ...
UV-B lamps are lamps that emit a spectrum of ultraviolet light with wavelengths ranging from 290–320 nanometers. This spectrum is also commonly called the biological spectrum due to the human body's sensitivity to light of such a wavelength. [1] UV-B light does not tan the skin very much, compared to the UV-A lamps that are used in tanning beds.
Physicians have recommended tanning devices to treat skin conditions. [57] [58] When UV light therapy is used in combination with psoralen, an oral or topical medication, the combined therapy is referred to as PUVA. [59] [60] A concern with the use of commercial tanning is that beds that primarily emit UVA may not treat psoriasis effectively.
Light-emitting diode therapy (LEDT) is a clinical approach that applies different wavelengths of light to cure diseases or conditions with skin-safe lights. Following NASA's innovation in the 1990s with Light Emitting Diodes (LEDs) that emit a specific narrow light spectrum, LED Therapy (LEDT) showed significant potential. [ 1 ]
