The Impact of Cold Weather on Varicose Veins

Varicose veins are a common medical condition causing enlarged, twisted veins that often appear blue or purple and can be seen just under the surface of the skin. Varicose veins usually occur in the legs but can also happen in other parts of the body. Symptoms include twisted and enlarged veins, swelling, aching, throbbing, or cramping in the legs, itchy or irritated skin, skin discoloration or thickening near the veins, and bleeding from the veins in severe cases.

While they are not usually harmful, they can cause discomfort, leading to more serious complications if left untreated. 


Varicose veins are caused by a weakening or damage to the valves within the veins that help regulate blood flow. When these valves do not function properly, blood can flow backwards and pool in the veins, causing them to stretch and become twisted. Causes include:

  • 1. Age and genetics can impact the valves and cause the varicose problem.
  • 2. Women are more likely to develop varicose veins than men, likely due to hormonal changes during pregnancy and menopause.
  • 3. The increased blood volume and pressure during pregnancy can put extra strain on the veins, leading to the development of varicose veins.
  • 4. Excess weight can pressurize veins in the legs. 
  • 5. Jobs that require long periods of standing or sitting can increase the risk of developing varicose veins.
  • 6. Cold can also impact varicose veins. 

Impact of cold weather on varicose veins

  1. Constriction of blood vessels: Cold temperatures can cause blood vessels to constrict or narrow, which can make it more difficult for blood to flow through veins. This can worsen the symptoms of varicose veins, such as pain, swelling, and heaviness in the legs.
  2. Reduced physical activity: During cold weather, people tend to be less active and spend more time indoors, leading to decreased blood flow and worsening the symptoms of varicose veins.
  3. Dehydration: Cold weather can cause dehydration, which can make the blood thicker and more difficult to flow through the veins. This can increase the risk of blood clots forming in the veins.
  4. Changes in atmospheric pressure: Changes in atmospheric pressure during cold weather can affect blood flow and lead to changes in the diameter of blood vessels, worsening the symptoms of varicose veins.
  5. To minimize the impact of cold weather on varicose veins, it is important to stay hydrated, maintain a healthy weight, exercise regularly, and wear warm clothing to keep the legs warm.
