Anatomy
High temperatures can also explain why veins appear more prominent at certain times. When it’s hot, the body activates mechanisms to regulate its temperature, including the dilation of blood vessels . This allows heat to be released through the skin, but at the same time, it causes the veins to expand and become more visible. That’s why it’s common to notice them more after a hot bath , during the summer, or after prolonged sun exposure.
