In the last decade, awareness of the harmful effects of solar ultraviolet radiation has increased. Modern lifestyles, outdoor occupations, sports and other activities make total sun avoidance impossible. Children spend more time outdoors than adults and there is compelling evidence that childhood is a particularly vulnerable time for the photocarcinogenic effects of the sun. Sun exposure among infants and pre-school age children is largely depend on the discretion of adult care providers. It is important to learn safe habits about sun-safety behaviours during the childhood. Children deserve to live and play in safe environments, and it is the responsibility of every adult to help children stay safe. Protecting children from excessive sun exposure is protection from sunburn today and other forms of sun damages, especially skin cancers, in the future.
