Veins in the hands and arms may bulge during a shower due to increased blood flow and vasodilation caused by warm water. The heat causes blood vessels to expand, allowing more blood to circulate closer to the skin's surface. This response is part of the body's mechanism to regulate temperature and enhance heat dissipation. Additionally, physical activity or muscular contractions while showering can further contribute to the prominence of veins.
