Exposure and sun protection practices of university students

the sample consisted of 385 young and data collection conducted through a form. Of the total, 239 (62%) young people were classified as skin type III and IV and 69 (17.9%) affirmed to have a history of skin cancer in the family. Most affirmed exposure to the sun between 10 a.m and 04 p.m and for more than one hour; 112 (29.1%) informed not employ safeguards. Among those who use sunscreen, the minority does so regularly.

Conclusion:

although the sample was made up of people with greater access to information, it was found exposure and sunscreen improperly. Education, individual and collective actions should be strengthened and prioritized given the incidence of skin cancer in the country.
