What are the signs of overexposure to UV rays?

The signs of overexposure to UV rays include redness, blistering, and discomfort on the skin. This is a typical response of the skin to excessive ultraviolet radiation, which can cause sunburn and other immediate effects. When the skin is subjected to high levels of UV rays, the body's inflammatory response kicks in, leading to increased blood flow to the affected areas, resulting in redness. Blistering indicates a more severe reaction, where the skin has been damaged enough to form fluid-filled sacs as a protective mechanism. Discomfort, which can include pain or a burning sensation, is also a common symptom of overexposure, reflecting the skin's distress from the UV damage.

In contrast, the other options do not represent symptoms associated with UV overexposure. Moisturized skin and a golden glow suggest healthy tanning and hydration, which should not be confused with the harmful effects of UV exposure. No change in skin color suggests that the skin has not been affected by UV rays, and smoother skin texture does not indicate overexposure; instead, it may imply proper skincare or maintenance. Thus, option A accurately describes the acute harmful effects of excessive UV exposure on the skin.
