High temperatures can also be a factor. In hot weather, the body tries to regulate its temperature by dilating blood vessels, which allows heat to escape more easily through the skin. This can make veins more visible after a hot bath in the summer or after prolonged sun exposure.
While visible veins are generally not a cause for concern, certain situations require closer attention. For example, if veins appear swollen, change color, or are accompanied by pain, a feeling of heaviness, or burning, it could be varicose veins or a circulatory problem, such as phlebitis or, in more serious cases, thrombosis. If these symptoms occur, it is advisable to consult a specialist for a thorough medical examination
