Final answer:
Excessive sweating can cause flushed skin due to the dilation of the blood vessels in the skin.
Step-by-step explanation:
The condition that would MOST likely cause flushed skin is excessive sweating.
When we sweat, arterioles in the dermis dilate so that excess heat carried by the blood can dissipate through the skin, resulting in flushed skin. This is often seen when individuals engage in physical activities and their body temperature rises.
For example, when you exercise, your body releases sweat to cool down. As a result, the blood vessels in your skin dilate, and more blood flows near the surface, making your skin appear flushed or red.
