Varicose Veins and Summer Heat: Why Symptoms Get Worse

Summer is a great time to enjoy the outdoors, but for many people with varicose veins, warmer temperatures can make leg symptoms noticeably worse. Increased swelling, aching, heaviness, and fatigue are common during the summer months and are often signs of underlying venous insufficiency. Understanding why this happens can help patients manage their symptoms and know when it is time to seek treatment.

At the Vascular Center and Vein Clinic of Southern Indiana, board-certified vascular surgeon Dr. Ricardo Vasquez has over 20 years of experience diagnosing and treating varicose veins, venous insufficiency, and leg swelling. His office includes a fully accredited vascular ultrasound lab, allowing patients to receive immediate, in-office evaluation without hospital delays. Dr. Vasquez and Monroe Hospital were recognized as a Top 50 Vascular Surgery Hospital in the Nation by Healthgrades in 2024—the only hospital in Indiana with this distinction.

Why Heat Makes Varicose Veins Worse

When temperatures rise, the body’s blood vessels naturally widen to help release heat. This process, called vasodilation, allows more blood to flow near the surface of the skin to cool the body.

For patients with varicose veins, however, widened veins make it even more difficult for blood to return to the heart. Blood pools in the legs, increasing pressure within the veins. As a result, many patients notice worsening swelling, aching, heaviness, and visible vein enlargement during hot weather.

Common Summer Symptoms

Patients with varicose veins often report that their symptoms become more noticeable after spending time outdoors or standing for long periods in the heat. Common symptoms include aching or throbbing legs, swelling around the ankles, a feeling of heaviness, nighttime cramping, and increased fatigue in the legs.

Some patients also experience itching, skin irritation, or worsening discoloration around the lower legs. These symptoms are often temporary but may indicate that venous disease is progressing.

Tips to Reduce Summer Symptoms

Fortunately, a few simple measures can help improve circulation during warmer months. Staying well hydrated, taking frequent walking breaks, avoiding prolonged standing or sitting, and elevating the legs whenever possible can all help reduce venous pressure.

Compression stockings may also help minimize swelling, particularly for patients who spend long hours on their feet. When spending time outdoors, taking breaks in the shade or air conditioning can also provide relief.

While these strategies can improve symptoms, they do not correct the underlying vein disease.

Why Early Evaluation Matters

If your symptoms are becoming more frequent or severe each summer, it may be time for a vascular evaluation. The most effective way to diagnose venous insufficiency is through vascular ultrasound, which evaluates blood flow and vein valve function.

At Dr. Vasquez’s office, patients receive same-day, in-office ultrasound in a fully accredited vascular lab. Because the ultrasound, consultation, and treatment planning occur in one location, patients avoid unnecessary referrals, hospital scheduling delays, and additional facility fees. This streamlined approach allows Dr. Vasquez to diagnose the problem and recommend the most appropriate treatment during the same visit.

When to Schedule an Appointment

If summer heat is making your legs feel heavier, more swollen, or increasingly uncomfortable, don’t assume it’s just part of the season. These symptoms may be signs of progressing venous disease that can be effectively treated.

You do not need a referral to be evaluated.
