After a brain tumor halted her dream of dancing at the collegiate level, interdisciplinary studies major Brooke Kotrla has returned to Texas Tech to finish the degree she started in 2015.Light therapy—or phototherapy, classically referred to as heliotherapy—consists of exposure to daylight or to specific wavelengths of light using polychromatic polarised light, lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light.
Light exposure administered to the eyes before or after the nadir of the core body temperature rhythm can affect the phase response curve.
UV-A, combined with psoralen, a drug taken orally, is known as PUVA treatment.
In UVB phototherapy the exposure time is very short, seconds to minutes depending on intensity of lamps and the person's skin pigment and sensitivity.
The therapy offers a wide range of options: UVA1 for acute AD, NB-UVB for chronic AD, and balneophototherapy have proven their efficacy over the recent past.
Patients tolerate the therapy safely but, as in any therapy, there are adverse effects and care should be taken in its application, particularly to children.
