Why some people’s veins are extra blue
If you’re super thin or a hardcore athlete, those veins might stand out even more. When you work out or do heavy lifting, your muscles swell and push those veins closer to the surface — that’s why weightlifters have those “pop-out” veins everyone envies. Pregnant women also tend to see more prominent veins because their circulatory system is working overtime.

But there’s a flip side. Sometimes, blue or bulging veins could be a sign of varicose veins — veins that have become stretched, twisted, and weak.
On your hands, they might look like thick, rope-like, zigzag lines that are bigger than normal. While often painless, varicose veins can cause discomfort and sometimes signal more serious health risks.
