The sun is not good for those who suffer from varicose veins

Those who suffer from varicose veins often hear: "Sit out in the sun, it's good for you..." This isn't true, and in fact you risk further damaging your health and making the situation worse. This is due to a thermal effect, as high temperatures produce vasodilation, a mechanism by which the body cools itself by widening blood vessels. In people suffering from venous insufficiency, this further dilation increases blood pooling in the legs, intensifying pain, swelling, fatigue, and intense heat.  

But how did the myth about the sun being beneficial for those suffering from varicose veins come about? 

It likely stems from a confusion between a feeling of well-being and a true therapeutic effect. Heat is relaxing and provides a pleasant sensation: lying in the sun can temporarily make your legs feel less stiff or more relaxed. However, this doesn't mean that varicose veins are improving. Furthermore, tanning can make veins less visible: tanned skin can temporarily mask the color of superficial veins, giving the impression that they've diminished.

For varicose veins, the following are useful:

• walking and doing regular physical activity;
• avoid standing or sitting still for long periods;
• keep your legs raised when possible.

Especially when you're at the beach, you often walk, swim, and move your legs more. The cool water and the contraction of your calf muscles can actually promote venous return.
