Avoid repeated prolonged standing or sitting
Think about your working conditions and habits. If you have to stand for a long time without any muscle activity in your legs, or you have to sit still for a long period (desk job), you should treat your legs with a proper rest and elevation after such a stress. In addition, you should activate your calves and other leg muscles as often as possible by stretching, flexing and extending, or walking around for a few minutes. When at home, elevate your feet.
Keep your veins functioning properly
Take care of your veins before they get too tired or overloaded with stress and negligence. Keep them healthy and they will keep you pretty.
