Blood Clots in Cold Weather: Everything You Need to Know

Blood Clots in Cold Weather: Everything You Need to Know

North Atlanta Vascular Clinic and Vein Center


Winter is the time when most people suffer from various diseases such as fever, cough, flu, and several other heart and lung diseases. A blood clot is another such condition that can occur during cold weather. Blood clots, also known as thrombi, are gel-like masses formed by blood coagulation. Clotting is a natural and necessary process that prevents excessive bleeding when a blood vessel is injured. However, abnormal clotting can occur, leading to the inappropriate formation of blood clots, which can pose serious health risks.

According to research, cold temperatures restrict our blood vessels. As a result, our blood circulation deteriorates, limiting oxygen supply to numerous body regions. Due to this, the blood becomes thicker, which may increase the risk of clot formation. This is partly due to the body's natural response to cold, which tries to maintain warmth by thickening the blood. Thicker blood can impede circulation and increase the risk of conditions like deep vein thrombosis (DVT).

Exposure to prolonged cold weather causes blood clots. In this blog, you will learn everything about blood clots in cold weather.

Impact of Cold Weather on Blood Circulation

You may have questions like, "Does cold weather affect blood circulation?" Well, the truth is yes, cold weather can have a serious impact on blood circulation.

Here are the effects of cold weather on blood circulation:

  • Peripheral Vasoconstriction: Blood vessels near the skin's surface constrict in response to cold temperatures, reducing blood flow to extremities.
  • Blood Thickness: Cold weather can increase blood viscosity (thickness), potentially raising the risk of clot formation.
  • Heart Rate and Blood Pressure: The body may increase heart rate and blood pressure in cold weather to maintain core temperature, affecting overall cardiovascular function.
  • Raynaud's Phenomenon: Cold weather can exacerbate symptoms of Raynaud's phenomenon, causing spasms in blood vessels of fingers and toes, leading to reduced blood flow.
  • Reduced Physical Activity: Cold weather may discourage outdoor exercise, contributing to a more sedentary lifestyle that can negatively impact circulation.
  • Risk of Hypothermia: Prolonged exposure to cold weather can lead to hypothermia, impacting the heart's ability to pump blood effectively.
  • Arterial Function: Exposure to cold temperatures may influence arterial function, potentially affecting blood flow and vascular health.

Major Symptoms of Blood Clots

Blood clots can occur in various conditions that have different symptoms. Some of the symptoms are as follows:

  • Swelling: Your leg or arm might swell, feel tender, or ache where the clot is.
  • Redness or Discoloration: Skin around the clot area may appear red or discolored.
  • Warmth: The skin might feel warm in the area of the clot.
  • Pain: You might experience persistent pain or tenderness, especially in your legs.
  • Breathing Problems: Shortness of breath or chest pain could signal a clot in the lungs.
  • Dizziness or Fainting: Clots affecting blood flow to the brain might cause dizziness or fainting.
  • Coughing Blood: Coughing up blood could suggest a clot in the lungs.

Treatment Options for Blood Clots

The treatment for blood clots depends on several factors, including the type and location of the clot, the individual's overall health, and any underlying conditions. Here are common treatment options for blood clots in cold weather:

  • Anticoagulant Medication: Unfractionated heparin, low molecular weight heparin, warfarin, and direct oral anticoagulants are the most often prescribed blood thinners.
  • Thrombolytic Therapy: The use of fibrinolytic medicines, which break up fibrin, a key component of clots, is part of thrombolytic pharmacological treatment. Normally, these drugs are injected into the clot using intravenous catheters.
  • Compressed Stockings: Compression stockings reach the calf or groin and increase blood flow from the lower extremities to the heart. This may aid in the relief of discomfort and swelling in the legs or arms caused by damaged blood vessels, a condition known as post-thrombotic syndrome.
  • Mechanical Thrombectomy: This is a minimally invasive surgery that involves the removal of blood clots, is often used for stroke therapy or the removal of clots in the arterial system, and has contributed to a significant reduction in stroke-related disability and mortality.

Prevention Tips for Blood Clots

Preventing blood clots involves adopting lifestyle changes and strategies to reduce risk factors. Here are some prevention tips:

  • Perform regular physical activity to promote blood circulation
  • Maintain a healthy weight by eating a balanced diet
  • Stay hydrated
  • Avoid prolonged immobility
  • Quit smoking

When to Seek Medical Attention for the Blood Clots

If you suspect a blood clot and experience severe symptoms, such as difficulty breathing or chest pain, call emergency services immediately. Do not delay seeking help, especially if symptoms are sudden and severe.
