Task: Answer Verification
Input (English): Question: Does total body exposure to ultraviolet radiation influence plasma levels of immunoreactive beta-endorphin in man?
Answer: On the basis of these results, the skin does not appear to contribute significantly to the levels of circulating betaE or ACTH. These data offer no support for the hypothesis that exposure to UVR leads to an increased concentration of circulating betaE, which could contribute to the feeling of well-being that often accompanies sun-bathing.
Output (English): no
