Question: 1 / 400

What can increased sensitivity of the skin signify?

Over-exposure to sunlight

Dehydration

Increased sensitivity of the skin can indeed signify dehydration. When the skin lacks adequate moisture, it becomes less resilient and more prone to irritation and sensitivity. Dry skin can disrupt the skin's barrier function, making it more susceptible to external irritants, allergens, and various environmental factors. This heightened sensitivity can manifest as redness, itching, or a burning sensation.

While over-exposure to sunlight can lead to sunburn or photo-sensitivity, the focus here is on sensitivity due to a lack of moisture. Excessive moisture, on the other hand, can lead to a condition known as maceration, where the skin becomes too soft and weak, but this does not typically result in increased sensitivity in the same way that dehydration does. Similarly, infections can cause sensitivity, but they often present with additional symptoms like swelling, redness, and discharge, not merely increased sensitivity alone. Thus, dehydration stands out as a primary cause of heightened sensitivity in the context of skin health.
