“…For example, exposure to suberythemal doses of sunshine on hands, arms and face two or three times per week is more than adequate to satisfy vitamin D requirements (Holick, 2002). Use of a more direct method of assessing sunshine exposure, such as UV dosimetry may be a more meaningful approach for assessing summer sunshine exposure as a determinant of serum 25 (OH) D levels (Terenetskaya, 2004).…”

“…Despite these weaknesses, it provides important information on doses of sun exposure needed for adequate vitamin D synthesis while avoiding dangerous overexposure to the sun. Other studies (26,30) have also provided data on estimated UV exposure times required for vitamin D synthesis using in vitro systems such as spectrophotometric analysis of the previtamin D content in ethanol solutions of 7-dehydrocholesterol during UV exposure. A particular strength of the study by Webb & Engelsen (26) was that it predicted sun exposure times needed for adequate vitamin D synthesis for different skin types.…”

“…It should be pointed out, however, that these questionnaires are crude estimates of sunshine exposure. Use of a more direct method of assessing sunshine exposure, such as ultraviolet dosimetry, may be a more meaningful approach for assessing summer sunshine exposure as a determinant of serum 25OH-D levels 52 . Vitamin D intake was not associated with wintertime serum 25OH-D levels in postmenopausal women in the present study.…”
