Many factors need to be considered including geographical location such as latitude, season, time of day, skin colour, age and particularly clothing.ĭermatologists have expressed concern about relaxation of sun protection messages, which have played a large role in the media campaigns to reduce the incidence of skin cancers. Guidelines on exposure to sunshine need to be tailored to the individual − one size does not fit all. 1 Certainly, avoidance of the most dangerous ultraviolet exposure in the middle of the day is appropriate, especially in summer, with responsible use of ultraviolet blocking agents. Recommended exposure of 5–15 minutes of sunlight 4–6 times a week outside the hours of 10 am–2 pm seems prudent ( Table 1 ). It is a subject where there has often been a lack of consensus among medical specialists themselves and this problem is further compounded in transferring this message to the public. Much controversy has surrounded the topic of how much sunshine is enough and how much is too much.

Guidelines on sun exposure must be tempered by the high prevalence of skin cancers in this country.
