If your legs feel more swollen, achy, or heavy during the summer months, you’re not alone. Heat can cause varicose veins to swell and symptoms to intensify—especially if you already suffer from chronic venous insufficiency. At Gauld Vein and Vascular, we often see a seasonal increase in patients seeking relief from heat-induced vein issues.

When it’s hot outside, your veins naturally dilate (expand) to help your body cool down. But for those with vein disease, this dilation increases pressure within already-weakened veins. As a result, blood pools more easily in the lower legs, causing discomfort, swelling, and more visible vein bulging. Add in summer travel, long days on your feet, and dehydration—and it’s a recipe for worsening symptoms.

Tips for Managing Varicose Veins in Warm Weather
To keep your symptoms at bay, try elevating your legs when resting, drinking plenty of water, and wearing compression stockings during the day. Light exercise like walking or swimming can also promote healthy circulation. If your symptoms don’t improve—or worsen—it may be time to explore more advanced treatments.

Minimally invasive options like radiofrequency ablation (RFA), sclerotherapy, or endovenous laser therapy (EVLT) can effectively close off problematic veins and redirect blood flow to healthier ones. These treatments are often performed in-office with little to no downtime—making summer a great time to address your vein concerns.

FAQs
Is it dangerous if my varicose veins get worse in the summer?
Worsening symptoms may signal progression of vein disease. It’s best to get evaluated before complications like ulcers develop.

Can heat cause new varicose veins to appear?
Heat doesn’t directly cause new veins but can exacerbate existing vein weakness and accelerate their appearance.
