Why do veins appear on hands?

Reasons for Visible Veins on Hands

Veins can become more prominent on the hands for a variety of reasons. As people age, their skin loses some of its elasticity and fat, which can lead to a more pronounced appearance of veins. Additionally, physical activity and increased blood flow can cause veins to swell, making them more noticeable. Other factors such as genetics, body temperature, and overall health can also play a role in how visible veins are on the hands.
