Fotosensitoituneiksi

Fotosensitoituneiksi is a Finnish term that translates to "photosensitized" or "made photosensitive." It refers to a state where a substance or organism becomes abnormally sensitive to light, particularly ultraviolet (UV) radiation. This increased sensitivity can lead to various effects, depending on the context.

In the realm of chemistry, photosensitization involves a molecule absorbing light energy and then transferring that energy to another molecule, initiating a chemical reaction that would not otherwise occur. This process is crucial in many photochemical reactions, including photosynthesis and some types of photopolymerization. The photosensitizer acts as a catalyst, enabling light-driven transformations.

In biology and medicine, photosensitization can occur when a person or animal is exposed to certain drugs, chemicals, or naturally occurring compounds that absorb light. When exposed to sunlight or artificial UV sources, these compounds can trigger adverse reactions. These reactions can manifest as skin rashes, burns, itching, or more severe dermatological conditions. Certain medical treatments, like photodynamic therapy (PDT), intentionally use photosensitizing agents to destroy abnormal cells, such as cancer cells, when activated by light. However, unintentional photosensitization from medications is a common side effect for some individuals. Avoiding direct sunlight or using strong sun protection is often recommended for those who are photosensitized.
