Rising UV radiation fuels skin cancer surge in Germany by 2023

Climate change is increasing UV radiation exposure, raising concerns about skin-related diseases. In Germany, skin cancer cases have surged in recent years, with over 100,000 treatments recorded in 2023 alone. Experts warn that proper sunscreen use is critical to reducing health risks. The sun emits energy, with about eight percent reaching Earth as UV radiation. This radiation is split into UVA, UVB, and UVC rays, each with different wavelengths. While UVC is entirely blocked by the ozone layer, UVA and UVB penetrate the atmosphere and can harm the skin.

Sunscreens help protect against these rays using two types of filters: organic (chemical) and physical (mineral). The European Commission advises that UVA protection should be at least one-third as strong as the SPF rating. For full-body coverage, Germany’s Federal Office for Radiation Protection recommends four heaped tablespoons for an adult. To reach the labelled SPF, users must apply two milligrams of cream per square centimetre of skin.

However, some chemical filters, like octocrylene, degrade over time. Authorities caution against using such sunscreens for more than one summer season. The rise in UV-related illnesses highlights the need for effective sun protection. Proper application and regular replacement of sunscreen can reduce the risk of skin damage. Authorities continue to stress the importance of following guidelines to stay safe in the sun.
