There are many reasons why someone might have cold feet. It could be due to the weather, poor circulation, Raynaud’s phenomenon, or diabetes among several other causes.
In most cases, cold feet are nothing to worry about and can be easily remedied. However, cold feet can also be a symptom of a more serious condition.
In this article, we will go into detail about the causes of cold feet and when you need to see your doctor.
We will also discuss how your doctor will diagnose the underlying condition and how to properly care for your feet to avoid this and other foot complications.
Why do I have cold feet?
The temperature is not the only reason you may be experiencing cold feet as there are a few different causes of it.
Poor circulation is one of the most common causes, as it can prevent blood from reaching the extremities.
The lack of blood flow can be due to an underlying medical condition such as diabetes, or simply from sitting or standing in one place for too long.
Other causes range from Raynaud’s disease to anemia which is why it is important to understand if any underlying conditions may be causing your feet to be cold as treatments can vary.
If you have cold feet and do not believe it is caused by the temperature, please see your doctor for a possible diagnosis of the cause.
How does diabetes cause cold feet?
One of the most common causes of cold feet is poor blood flow which can be a result of diabetes, also called diabetes mellitus.
When you have diabetes, your body has difficulty using insulin to convert blood sugar called glucose into energy which can lead to nerve damage and circulatory issues.
The type of nerve damage is called diabetic neuropathy or peripheral neuropathy and is caused by high blood sugar levels over a long period of time.
The most common symptoms include loss of feeling, diabetic foot ulcers, infections, and sharp pains.
The numbness may make your feet seem cold although they have a normal temperature if you touch them.
Diabetes also puts you at risk for peripheral artery disease (PAD), also called peripheral arterial disease, although you can also get PAD if you do not have diabetes.
Peripheral artery disease causes poor circulation by narrowing the blood vessels that carry blood to your limbs and the symptoms can include cold feet as well as cramping, pain, or weakness in your legs among others.
What are other causes of cold feet?
There are many different causes of cold feet besides cold temperatures and diabetes which is why it is important to speak with your doctor if you experience this symptom on a regular basis. Other medical conditions that can cause cold feet include:
Anemia is a condition in which you do not have enough healthy red blood cells to carry oxygen throughout your body and the symptoms can include cold feet as well as fatigue, pale skin, shortness of breath, and dizziness.
Also called Raynaud’s phenomenon, Raynaud’s disease is a condition that causes the blood vessels in your extremities such as your fingers and toes to narrow in response to cold temperatures or stress which can decrease blood flow and cause cold feet.
Your hands and feet may turn pale and then blue and it is caused by cold temperatures, stress, and anxiety.
Frostbite is a cold-related injury that occurs when your skin and the tissue underneath it freezes and it can cause permanent damage.
The symptoms of frostbite include cold feet as well as numbness, hard or waxy-looking skin, and pain.
If you have an underactive thyroid it is called hypothyroidism.
Your thyroid is a butterfly-shaped gland in your neck and it produces hormones that help regulate your body’s metabolism.
When you have hypothyroidism, it means that your thyroid is not making enough hormones and its symptoms can include cold feet as well as fatigue, weight gain, constipation, and depression.
Stress or anxiety
When you are stressed or anxious your body produces adrenaline which can cause the blood vessels to constrict in your extremities as your body keeps your blood in your core which can cause cold feet as well as cold hands, sweating, and a rapid heartbeat.

Sitting or standing for long periods of time
If you sit or stand in one place for too long it can cause your feet to swell resulting in reduced blood flow that makes your feet feel cold.
It is especially common if you are on a long airplane flight, road trip, or living a sedentary lifestyle.
Also called thromboangiitis obliterans, Buerger’s disease is a rare condition linked to tobacco use that causes your blood vessels to swell and blood clots to form in the arteries and veins of your extremities.
The symptoms of Buerger’s disease include cold feet as well as pain, numbness, or tingling in your hands or feet.
High cholesterol is a condition in which you have too much cholesterol in your blood and it can cause the arteries to narrow and harden which decreases blood flow and can make your feet feel cold.
High cholesterol can also have no symptoms so it is important to get your cholesterol checked regularly by your doctor.
When do I need to see a doctor about cold feet?
- Ulcers or sores on your feet that take longer than normal to heal
- Weight loss or weight gain
- Joint pain
- Changes in your skin such as rashes, thickened skin, or scaly skin
If you are experiencing cold feet regularly accompanied by these symptoms please see your doctor, podiatrist (foot doctor), or health care provider for a diagnosis.
How does a doctor diagnose the cause of cold feet?
If you have cold feet on a regular basis it is important to speak with your doctor as they will be able to determine the cause and provide treatment.
Your doctor will ask about your medical history and symptoms and they may also order tests such as blood tests, imaging tests, or nerve conduction studies.
An electrocardiogram (EKG) may also be ordered to check your heart as it can be the cause of circulation issues.
Finally, an ankle-brachial index test may also be administered which is a test that measures the blood pressure in your ankles and compares it to the blood pressure in your arms to see if there are any discrepancies.
What are the best ways to treat cold feet?
There are several things you can do at home to treat cold feet and they include:
- Moving your body to warm up your feet such as running or even walking around
- Putting on warm socks or slippers
- Soaking your feet in a foot bath with warm water although if you have foot ulcers or other foot injuries you may need to avoid this method, or soaking your feet in general
- Using a heating pad
If your cold feet are caused by an underlying condition, then your doctor will suggest a treatment plan to help alleviate symptoms which could include lifestyle changes such as exercise or taking prescribed medications.
What are the best ways to prevent cold feet?
