Why Spider Veins Become More Noticeable in Winter

As temperatures drop and the days get shorter, many people start to notice their spider veins becoming more visible. If you’ve ever wondered why the thin, web-like veins on your legs or face seem to stand out more during the colder months, you’re not imagining it. Winter can make spider veins appear darker or more pronounced, even if they haven’t structurally changed.

Understanding why this happens can help you manage symptoms, support your circulation, and explore effective treatment options.

¿Qué son las arañas vasculares?

Spider veins are small, dilated veins near the surface of the skin. They appear red, blue, or purple, often branching in thin web-like patterns across the legs or face.

Los síntomas comunes incluyen:

  • Visible red, blue, or purple veins
  • Mild itching or burning
  • Aching or heaviness after standing

While often considered cosmetic, spider veins can be linked to early venous insufficiency. Learn more on our Spider Veins page.

Why Spider Veins Stand Out More in Winter

Several factors make spider veins more noticeable during the colder months:

1. Cold temperatures cause veins to constrict

In cold weather, blood vessels tighten to preserve heat. This constriction makes the skin appear lighter, increasing contrast and causing spider veins to look darker or more pronounced.

2. Dry winter skin increases visibility

Winter air can dry out the skin, making it appear thinner and emphasizing visible veins.

3. Reduced sun exposure enhances contrast

During summer, natural tanning darkens skin tone, helping mask spider veins. In winter, lighter skin creates stronger contrast.

4. Less physical activity affects circulation

Cold weather often leads to less movement. Reduced activity slows circulation, making spider veins more likely to show.

5. Tight winter clothing adds pressure

Leggings, tall boots, and thick socks can restrict blood flow, highlighting small surface veins.

Underlying Causes of Spider Veins That Persist Beyond Winter

Winter impacts visibility, but spider veins typically develop due to:

These factors can cause spider veins year-round, winter simply makes them easier to see.

How to Reduce Spider Vein Visibility During Winter

Although you can’t change the weather, you can support your vein and skin health:

Keep your legs warm

Warm muscles and vessels improve circulation.

Moisturize regularly

Hydrated skin minimizes contrast and reduces irritation.

Stay active indoors

Walking, stretching, and calf exercises promote blood flow.

Limit long periods of sitting or standing

Take breaks every hour to stretch or move.

Use compression stockings (if recommended)

Compression can help minimize discomfort and support healthy circulation.

When Spider Veins May Signal Something More Serious

These symptoms could indicate chronic venous insufficiency, where deeper veins struggle to return blood to the heart.

Winter Is a Great Time to Treat Spider Veins

Winter is ideal for spider vein treatment because:

  • Compression stockings fit easily under clothing
  • Limited sun exposure reduces risk of discoloration
  • You spend more time indoors, aiding recovery
  • Treatment completed now results in clearer legs for spring and summer

Treatment for Spider Veins

At United Vein & Vascular Centers, we treat spider veins exclusively with sclerotherapy, the gold-standard, minimally invasive solution for fading or eliminating unwanted veins. During the procedure, a small amount of medication is injected into the affected vein, causing it to close and gradually fade from view. Sclerotherapy requires no anesthesia, involves little to no downtime, and delivers consistent, effective results for patients looking to improve both the appearance and comfort of their legs.
