What are the potential short-term effects of tanning?

The potential short-term effects of tanning primarily include sunburn, skin irritation, and dehydration. When the skin is exposed to ultraviolet (UV) radiation from tanning beds or the sun, it can experience immediate adverse reactions. Sunburn occurs as a response to excessive UV exposure, resulting in redness, pain, and peeling of the skin. Skin irritation may manifest as rashes or discomfort, depending on the sensitivity of the individual's skin and the duration of exposure. Dehydration can occur as UV radiation damages the skin's outer layer, leading to dryness and loss of moisture, which is particularly relevant in the context of both outdoor sun exposure and indoor tanning.

In contrast, while skin cancer and wrinkles are significant concerns associated with prolonged and repeated tanning, they are considered long-term effects rather than short-term. Increased skin hydration is also misleading, as tanning typically leads to the opposite effect of skin drying out and becoming less hydrated. Allergic reactions may occur in some individuals, but they are not categorized as anticipated short-term effects for the general population who experience tanning. Thus, the effects that directly arise shortly after tanning sessions are accurately represented by the symptoms described in the correct answer choice.
