The American Academy of Family Physicians (AAFP) supports school-based measures to prevent harmful sun exposure to students. Educating students about sun safety, providing shaded areas to play outside, and minimizing outdoor recess during periods of the highest ultraviolet ray exposure are essential to prevent harmful sun exposure. The AAFP encourages the use of sun protective clothing, including hats. The AAFP encourages schools to allow students to self-apply sunscreen brought from home, as well as provide assistance in applying sunscreen with parental permission and with a second adult present for students who cannot apply sunscreen on their own. Students should not be required to have a letter from a health care provider to apply sunscreen at school. (2019 COD)
