If you are referring to veins that are difficult to cannulate for IV therapy or blood draws gently warming a limb with a warm towel helps (not hot, never in a microwave). If you are asking about overall vascular health some of the best ways to improve your vasular health are sensible eating, low fat diet, weight loss and moderate exercise. You should always consult your physician before making changes to diet or embarking on an exercise regimen.
