Why are the veins popping out of my hands and feet?

Question

It's so unpleasant seeing the veins sticking out of my hands and feet. This never happened to me until this year. What does this happen? Is there anything wrong with my hands and feet? How can I change this?

Answer 1

being overly hydrated does that.  

Answer 2

This happens to me too. Mine especially show when I am really hot or if I am dehydrated.  So maybe try drinking more water if you don;t drink a good amount already.
