The 93 participants in the study spent an average 22.4 hours per week outside without sunscreen and 28.9 hours per week outside with and without sunscreen. This translates to a mean of 11.1 hours per week of total body skin exposure with no sunscreen used, the authors calculate.
Despite this abundant sun exposure, 51 percent of these individuals were found to have low vitamin D levels, the researchers found.
“This implies that the common clinical recommendation to allow sun exposure to the hands and face for 15 minutes may not ensure vitamin D sufficiency,” Binkley and colleagues report.
