How can I prevent varicose veins and spider veins?

• Regular leg exercise to improve your leg strength, circulation, and veins such as walking or running.
• Weight control to avoid placing too much pressure on your legs.
• Don't cross your legs for long times when sitting.
• Elevate your legs when resting as much as possible, either while sitting or lying down.
• Don't stand or sit for long periods of time. If you have to then shift your weight from one leg to the other every few minutes. While sitting for a long periods of time, stand up and move around or take a short walk every 30 minutes.
• Wear elastic support stockings and avoid tight clothing that constricts your waist, groin, or thighs.
• Avoid wearing high heels for long periods of time. Lower-heeled shoes can help tone your calf muscles to help blood move through your veins.
• Eat a low-salt diet rich in high-fiber foods to avoid constipation which in long term can also lead to VV
• Spider veins on the face can be prevented by wearing sunscreen to protect  skin from the sun
