Many people notice that over time or under certain circumstances, the veins in their hands become more visible. Although this may seem alarming at first, it is usually harmless. However, it is important to be aware of it, as it can be a sign of physical changes or even health problems that require medical attention.
One of the most common causes of visible veins is a low percentage of body fat. People who are slim or very muscular generally have thinner skin, which makes the veins more visible. This phenomenon is even more pronounced in people who engage in regular physical activity, especially weight training or high-intensity exercises, as these temporarily increase blood flow, causing the veins to dilate and become more visible.
Another natural factor is aging. Over the years, the skin loses collagen, a protein that is essential for its firmness and elasticity. As it thins and loses elasticity, internal structures such as veins become more visible, especially on the hands, where the skin is naturally delicate.
