Cold Feet Symptoms
Cold feet can be uncomfortable and annoying to anyone they might touch, but are they really anything to worry about? In some cases, those chronically cold feet can be a sign of illness. [7,8] But in general, cold feet mean that your inner body has gotten a little too cool and your "core temperature" has dropped a little too low. To protect your vital organs (heart, lungs, and brain), your body diverts blood flow away from your hands and feet.  Nervousness can cause this diversion, too, which is why "getting cold feet" means suddenly backing out of something at the last minute. [2,6]
- Your feet feel cold, like "blocks of ice." 
- You might feel numbness, tingling, or pins-and-needles. 
- Foot color ranges from red to purple-blue to pale white. 
- Someone who touches your feet feels that they are cool or cold. 
- This can last a few minutes or a few hours to even days or longer. 
- Sometimes the cold feeling never really goes away. 
- Your feet might warm up in warm environments but go right back to feeling cold again with exposure to cold air or water. 
Who is most often affected by cold feet symptoms?
- Women. 
- Older people. 
- Anyone living or working in cold conditions. 
- Anyone with poor circulation. 
- Diabetics or others with peripheral nerve disease. 
Where in the world are these cold feet symptoms most common?
- Cold climates produce the coldest feet, of course. 
When are cold feet symptoms most likely to occur?
- Your cold feet symptoms may increase when you sit or lie down. 
- Of course, winter weather can cause cold feet. 
Are cold feet symptoms serious?
- Cold feet can point to a serious problem if the circulation to them is truly impaired; you have a nerve condition that's causing the problem; you have pain in your legs when walking; or your feet only seem cold to you and not to anyone else. [1,11]
- Cold feet are rarely serious in a younger person with no other illnesses. [2,10]
Cold Feet Causes Overview
Many conditions have cold feet as a symptom. Most of them have to do with circulation and blood flow, although thyroid, anemia, and nervous system disorders can be involved. [1,2,3]
Circulatory cold feet causes:
- Poor circulation due to your feet being in a cold environment is the most common cause of cold feet. It limits the amount of blood flow – and therefore heat – to your extremities. 
- Atherosclerosis or hardening of the arteries *Smoking makes your blood vessels tighten and constrict. 
- Cold weather causes blood vessels in your feet to constrict. 
- Feeling cold or nervous causes blood vessels in your feet to tighten. 
- Acute blood clots to the arteries in the legs can cause one foot to become acutely cold and painful. This is an emergency. 
Hormonal and deficiency related cold feet causes:
- Thyroid imbalances – too much or too little thyroid hormone – interfere with metabolism. 
- Megaloblastic anemia, which is a shortage of healthy red blood cells from Vitamin B 12 deficiency, can cause cold feet that often also burn. 
Nervous system cold feet causes:
- Peripheral neuropathy, or nerve damage, may cause you to feel numbness and tingling in your feet which you interpret as cold. 
- Panic disorder sends your body into fight-or-flight mode, diverting blood into your internal organs and out of your feet – leaving them cold. 
Infectious cold feet causes:
- Mononucleosis can lead to peripheral neuropathy. 
- Meningitis may have symptoms of both fever and cold feet. 
Physiological cold feet causes:
- Low body fat will make your body divert more blood flow to vital organs, trying to keep them warm. 
- Sometimes having cold feet is simply normal and a trait that runs in families. 
We've listed some specific conditions that can cause cold feet, along with how to identify each of them:
A.I. Health Assistant Causes for Cold Feet
The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced cold feet. This list does not constitute medical advice.
1.Mild Frostbite of the Lower Leg
Frostbite is tissue damage caused by exposure to the cold (at or below 32F or 0C). It is most commonly found in people doing leisurely activities like camping, hunting, or snow sports. It is also more likely in those who are intoxicated or have a mental disorder.
It takes 1-3 months to assess the damage, at which time, surgery might be needed.
- Top Symptoms:
- foot pain, swollen foot, foot numbness, foot redness, limping
- Symptoms that always occur with mild frostbite of the lower leg:
- cold toe
- Hospital emergency room
Primary Raynaud phenomenon is a disorder of the blood vessels, usually in the fingers and toes, which causes the blood vessels to narrow when feeling cold or stressed. When this happens, blood can't get to the surface of the skin and the affected areas turn white and blue.
This condition is considered irreversible, but it should not prevent you from living a healthy life.
- Top Symptoms:
- distal numbness, cold toe, cold fingers, spontaneous toe pain, spontaneous finger pain
3.Peripheral Arterial Disease (Pad)
Peripheral artery disease (PAD) occurs when the big blood vessels, called arteries, become too narrow due to clumps of fat (called plaques) building up inside the walls. If arteries become too narrow, not enough oxygen and nutrients are delivered to the muscles, skin, and organs. The arteries in the legs are often affected first, as they are the furthest from the heart.At first, PAD has no symptoms. As it gets worse, leg pain is likely to develop, leading to cramps in the calf, thigh, foot, or buttock upon exercise. PAD can also increase the risk of a blood clot if a piece of plaque detaches, leading to serious complications such as a heart attack or stroke.Peripheral artery disease is much more common in smokers and in people with diabetes. High blood pressure, high cholesterol, being overweight, and not getting much exercise also can put one at higher risk.
The prognosis of this disease is highly variable and depends heavily on habits, medical history, and genetics. Peripheral artery disease is a chronic non-life threatening condition. Managing the disease, however, is very important in reducing the risk for stroke and heart attacks, so make sure to follow-up with a physician.
- Top Symptoms:
- leg numbness, spontaneous foot pain, decreased exercise tolerance, cold feet, thigh pain
- Symptoms that never occur with peripheral arterial disease (pad):
- calf pain from an injury, thigh pain from an injury

Hypothyroidism occurs when the thyroid, a butterfly-shaped organ inside the neck, no longer produces adequate levels of hormones. Thyroid hormones are essential for many bodily functions including breathing, heart rate, and metabolism.
Most cases of hypothyroidism require lifelong hormone replacement therapy.
- Top Symptoms:
- fatigue, depressed mood, difficulty concentrating, weight gain, muscle aches
- Primary care doctor
5.Iron Deficiency Anemia
Anemia is a condition in which the body does not have enough healthy red blood cells, which deliver oxygen. Iron deficiency anemia occurs when the body does not have enough iron. Iron helps make red blood cells.
Resolves with treatment
- Top Symptoms:
- fatigue, headache, shortness of breath, dizziness, heavy menstrual flow
- Primary care doctor
Sepsis is a serious illness that is caused by the body's reaction to an infection and cause system-wide inflammation.
- Top Symptoms:
- being severely ill, shortness of breath, fever, feeling confused and not making sense while talking, abnormally high heartrate
- Symptoms that always occur with sepsis:
- being severely ill
- Emergency medical service
Cold Feet Treatments and Relief
Seek immediate treatment in the emergency room or call 911:
- If you have cold hands and feet as well as fever — this can be a sign of a serious infection or circulatory disorder. [8,12]
- If your feet are very cold and discolored, especially if they are also painful. This can mean a near-complete loss of circulation in your feet. [1,13]
Schedule an appointment for:
- Ongoing fatigue and feeling cold all over. 
- Uncomfortably cold feet which change color from white to purple to red. 
- Cold feet with ongoing numbness and tingling. 
Try these remedies at home for cold feet treatment:
- Increase exercise to improve circulation. 
- Layer silk or cotton socks beneath wool socks. [13,18]
- Warm hats and gloves preserve body heat and help prevent constriction of the blood vessels in your feet. [15,18]
- Drink warm beverages in cold weather. 
- Quit smoking. 
FAQs About Cold Feet
Here are some frequently asked questions about cold feet.
What causes cold feet?
Cold feet are usually caused by reduced blood supply. This can be the result of blockage or constriction of our blood vessels in the feet or lower leg.  When in a cold environment, our body is designed to primarily keep our heads and torsos warm, because these areas include all organs essential for life. These organs do not function as well if they drop in temperature. To keep our brains, hearts, lungs, and digestive organs warm, the body may divert warm blood from the fingers, toes, arms, and legs to the torso so that the central organs can be warm. This is the most common cause of cold feet. 
What causes poor circulation in the feet?
Cold exposure is a common cause.  It can also be a symptom of certain autoimmune diseases, blood disorders, or hypothyroid disease. [3,9] Exposure to select drugs and environmental factors can cause poor circulation.  Accumulation of lipid and fibrous material inside the arteries (called peripheral arterial disease, or PAD) can restrict blood circulation as well.  Smoking is an important risk factor for poor circulation. 
How to improve circulation in the feet?
Keep your whole body warm.  Don't smoke — smoking can make your symptoms worse. Avoid medicines that cause blood vessels to become narrow, such as cold medicines or diet pills. [19,20] Get your diabetes, high blood pressure, and high cholesterol under control (if you have these conditions.)  Walking helps increase circulation and relieve peripheral artery disease (PAD) symptoms too. Medication and surgeries can be considered if PAD is severe enough. 
Can cold feet be a sign of anemia?
Yes. Anemia is caused by a loss and/or impaired production of red blood cells. Blood loss and impaired production of red blood cells can both compromise blood flow to your feet, making your feet cold. [3,5] The compromise of blood flow comes from diversion of a limited blood supply. Blood will go to body parts where it is most needed, which is away from the arms and legs. 
When should you see a doctor for cold feet?
See a doctor if the problem persists, or you start to develop pain or open sores on your toes.  Additional symptoms, such as joint pain, muscle pain, fever, weakness, weight loss, rash, arthritis, or problems with heart or lungs might indicate underlying medical conditions that warrant medical attention as well. [9,22] Severe foot discoloration also warrants medical attention.
