Thread veins, also known as telangiectasia or spider veins, occur when capillaries (the
smallest of blood vessels) become permanently dilated and rupture, spreading blood to other
capillaries and leaving a fine red or blue tree-like appearance just beneath the skin.
Thread veins can be caused by genetics, age, smoking, alcohol, obesity, sun exposure, occupation, medical conditions, trauma or a sedentary lifestyle.
There are a number of things you can do to help prevent thread veins, including exercising daily to strengthen your legs, veins and circulation, maintaining a healthy weight to avoid too much weight on your legs, and wearing low-heeled shoes and loose clothing.
Do not cross your legs when sitting, try to elevate your legs when resting, don't stand still for too long and wear a good SPF as often as you can, even when it isn't sunny.
