Genetics plays a fundamental role in skin thickness and the arrangement of our veins. Some people inherit a more translucent dermis or more visible, superficial blood vessels, without this representing a premium in terms of medical risk.
Furthermore, body type and fat distribution determine how prominent the veins will be. Those with a lower percentage of body fat tend to notice this feature more, which is simply a personal anatomical trait.
Effects of exercise and temperature.
During intense physical activity, blood flow increases to deliver oxygen to the muscles, causing temporary vasodilation that makes veins swell and become more prominent. This is a standard, high-performance biological process for the body.
Similarly, ambient heat causes the body to expand its superficial blood vessels to dissipate body heat through the skin. This is why, in warm climates, it’s much more common to notice that our hands have brighter, more visible red veins.
