What is a sign of overexposure to UV radiation?

• A. Redness and peeling skin
• B. Dryness and itching
• C. Increased freckles
• D. Enhanced tan color

Answer: (A)

Redness and peeling skin is a classic indication of overexposure to UV radiation. When the skin is exposed to excessive levels of UV rays, it undergoes a process known as sunburn, which results in inflammation and irritation. This can manifest as redness, swelling, and pain. In more severe cases, the skin may begin to peel as the body works to shed the damaged cells and heal itself. Other options, while they can be associated with sun exposure, are not direct signs of immediate overexposure. Dryness and itching can occur from prolonged sun exposure but are more general symptoms rather than specific indicators of acute overexposure. Increased freckles may result from cumulative UV exposure but do not signify immediate harm or skin damage. Enhanced tan color could indicate some level of tanning, which is a protective response by the skin, but it does not necessarily mean overexposure has occurred.
