“…Twenty-six healthy volunteers were exposed to 15 J/cm² UVA irradiation on a single occasion, but this had no eVect on E level. Repeated irradiation of 35 subjects with UVA and UVB did not inXuence ATCH level either (Wintzen et al 2001). Gambichler et al (2002) published similar observations regarding immunoreactive E and metenkephalin.…”

Beta-endorphin (betaE) is an important reliever of pain. Various stressors and certain modalities of physiotherapy are potent inducers of the release of endogenous betaE to the blood stream. Most forms of exercise also increase blood betaE level, especially when exercise intensity involves reaching the anaerobic threshold and is associated with the elevation of serum lactate level. Age, gender, and mental activity during exercise also may influence betaE levels. Publications on the potential stimulating effect of manual therapy and massage on betaE release are controversial. Sauna, mud bath, and thermal water increase betaE levels through conveying heat to the tissues. The majority of the techniques for electrical stimulation have a similar effect, which is exerted both centrally and--to a lesser extent--peripherally. However, the parameters of electrotherapy have not yet been standardised. The efficacy of analgesia and the improvement of general well-being do not necessarily correlate with betaE level. Although in addition to blood, increased brain and cerebrospinal fluid betaE levels are also associated with pain, the majority of studies have concerned blood betaE levels. In general, various modalities of physical therapy might influence endorphin levels in the serum or in the cerebrospinal fluid--this is usually manifested by elevation with potential mitigation of pain. However, a causal relationship between the elevation of blood, cerebrospinal fluid or brain betaE levels and the onset of the analgesic action cannot be demonstrated with certainty.

“…68 However, significant increases in plasma opioid levels after tanning have yet to be demonstrated in human subjects. 69,70 Other investigations of the effect of UV light on mood have focused on the photosensitivity of the pineal melatonin-generating system. The enzyme N-acetyltransferase, which initiates the conversion of serotonin to melatonin, is reported to be inhibited by UVA radiation.…”

“…While earlier studies found increased levels of endorphins following UVL exposure, 14,15 subsequent studies have not confirmed these findings. 16,17 Another investigative approach to the endorphin theory of tanning behavior would be to evaluate positron emission tomography brain images of subjects identified by mCAGE and mDSM-IV-TR as possibly having an SRD with respect to UVL tanning. Comparisons of observations following control (sham) vs actual exposure to UVL would be analogous to research approaches used to study other human addictions.…”

To better understand the complex motivations involved with UV light (UVL) tanning behavior.Design: Two written instruments, the CAGE (Cut down, Annoyed, Guilty, Eye-opener) Questionnaire, used to screen for alcohol abuse or dependence, and the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria for substance-related disorders, were modified to evaluate subjects for a substance-related disorder involving UVL tanning.
