Prevention is definitely worth thinking about, especially with a strong family history. While you can't change your genetics, there are several lifestyle factors that can help reduce your risk or delay the onset of spider veins. Regular exercise, particularly activities that promote good circulation like walking, swimming, or cycling, can be beneficial. Maintaining a healthy weight reduces pressure on your leg veins. If your job involves a lot of standing or sitting, try to move around regularly and elevate your legs when possible. Compression stockings can be helpful if you're on your feet all day. Protecting your skin from excessive sun exposure, especially on your face, is important too. Avoiding crossing your legs for long periods and watching your sodium intake can also help. While these measures won't guarantee you'll never develop spider veins, they can certainly reduce your risk and are good for your overall health anyway.
