We suggest that the risks and benefits to individual and population health of different patterns of sunlight exposure are poorly characterised. Furthermore, we believe that the risks of excess exposure to sunlight in North European countries have been overstated and that the potential benefits of exposure to sunlight (particularly in moderation) have been largely ignored. We contend that a re-appraisal of these risks and benefits is required to allow us to better formulate public health policy and to provide the public and individuals with appropriate advice.
