Heliotherapy: A South African perspective

The research objective was to gather and collate data that will enable dermatologists to quantify exposure to solar radiation so that they can give accurate advice to patients using heliotherapy, thereby minimising harm from sun exposure. Other patients can also be advised regarding ultraviolet index (UVI) and sun safety. The concept of minimal erythema dose per hour (MED/h) may be useful in future research into solar radiation and its effects on skin cancer
