El peligro del bronceado: ¿por qué el sol no es tan seguro como creemos?

The Asociación Española Contra el Cáncer (AECC) has issued a warning against the perception of tanning as a sign of health or beauty, emphasizing that no level of tanning is safe. The organization states that the darkening of skin, often sought during summer months, is a biological response to damage caused by ultraviolet B (UVB) radiation, not a protective mechanism. This damage can lead to DNA mutations and increase the risk of skin cancer, including melanoma.

The AECC’s message comes amid a surge of social media advice promoting quick or intense tanning methods, which scientific evidence discourages. The association highlights that tanning beds are particularly hazardous, classified as carcinogenic in all forms. Adriana Fonte, a prevention specialist with the AECC in Madrid, notes that up to 50% of cancer diagnoses could be prevented, with skin cancer being one of the most avoidable types.

Recent data shows a 40% rise in skin cancer cases over four years, a trend that has alarmed healthcare professionals. The AECC also refutes the belief that sun exposure is necessary for vitamin D synthesis, stating that sunscreen does not hinder this process and that supplements offer a safer alternative for those with deficiencies. The organization stresses that solar damage accumulates over time, contributing to premature aging and cancer risk, with experts noting that “the skin has memory.”

Protective measures, such as daily sunscreen application and avoiding peak sun hours, are recommended year-round. Dermatologist Ana Molina explains that UV-A radiation, even on cloudy days, can degrade collagen and elastin, leading to wrinkles and age spots. She advises using the “shadow rule” to gauge safe exposure times and applying sunscreen consistently, regardless of the season.

The AECC is also launching youth-focused programs to foster early adoption of sun-safe behaviors, framing photoprotection as a lifelong health priority rather than a cosmetic concern. As summer approaches, the organization’s message is clear: safeguarding skin is essential for long-term well-being.
