Do your hands and feet often feel unusually cold even when the surrounding temperature is comfortable? Poor circulation, anaemia, thyroid problems and other health conditions may be responsible.
Introduction
Have you ever noticed that your hands and feet feel cold while the rest of your body feels perfectly warm? Perhaps you are indoors, the weather is hot, and other people around you are comfortable, but your fingers and toes still feel unusually cold.
Occasional cold hands and feet are not necessarily a cause for concern. The body naturally adjusts blood flow to regulate its temperature. However, when the sensation happens frequently, lasts for a long time or occurs without an obvious reason, it may be worth investigating.
Cold hands and feet can sometimes be associated with problems affecting blood circulation, the nerves, hormone levels or the blood’s ability to carry oxygen.
8 Possible Reasons Your Hands and Feet Feel Cold
Here are eight possible reasons your hands and feet may feel cold even in warm weather.
1. Poor Blood Circulation
One of the common explanations for persistently cold hands and feet is reduced blood flow to the extremities.
The heart pumps blood throughout the body, delivering oxygen and nutrients to different tissues. When circulation is reduced, less warm blood may reach the hands and feet, making them feel colder than other parts of the body.
Conditions affecting the blood vessels, including peripheral artery disease, can reduce circulation, particularly in the legs and feet.
Other possible signs include leg pain when walking, numbness, tingling, slow-healing wounds and changes in skin colour.
2. Anaemia and Iron Deficiency
Anaemia occurs when the body does not have enough healthy red blood cells or haemoglobin to carry sufficient oxygen to its tissues.
Iron deficiency is one of the common causes of anaemia. When haemoglobin levels are low, the body may struggle to deliver oxygen effectively, and some people experience cold hands and feet.
Other symptoms may include persistent tiredness, weakness, dizziness, headaches, pale skin and shortness of breath, particularly during physical activity.
Women with heavy menstrual bleeding, pregnant women and people with diets low in iron may have an increased risk of iron deficiency.
3. Underactive Thyroid (Hypothyroidism)
The thyroid gland produces hormones that help regulate metabolism, energy use and body temperature.
When the thyroid gland is underactive, a condition known as hypothyroidism, the body may produce less energy and heat than normal. As a result, a person may feel unusually cold, even when other people are comfortable.
Cold hands and feet may occur alongside other symptoms such as unexplained weight gain, constipation, dry skin, hair thinning, fatigue and a slower heart rate.
A blood test can help determine whether thyroid hormone levels are abnormal.
4. Raynaud’s Phenomenon
Raynaud’s phenomenon is a condition in which the small blood vessels supplying the fingers and toes temporarily narrow, reducing blood flow.
Although it is commonly triggered by cold temperatures or emotional stress, some people experience episodes in situations that do not seem particularly cold.
During an episode, the affected fingers or toes may become unusually cold, numb or painful. Their colour may also change, often turning white or blue before becoming red as circulation returns.
Raynaud’s can occur on its own or alongside autoimmune conditions such as lupus and systemic sclerosis. Frequent, severe or newly developing symptoms should be assessed by a healthcare professional.
5. Diabetes and Nerve Damage
Diabetes can affect both blood vessels and nerves, particularly when blood sugar levels remain poorly controlled over time.
One possible complication is diabetic peripheral neuropathy, which damages the nerves in the feet and sometimes the hands.
When the nerves are affected, a person may experience tingling, burning, numbness or unusual temperature sensations. Some people feel as though their feet are cold even when they are not actually colder to the touch.
Diabetes can also damage blood vessels, contributing to circulation problems.
People living with diabetes should pay attention to changes in their feet, especially wounds, discolouration, swelling or reduced sensation.
6. Low Body Weight and Inadequate Nutrition
The body needs enough energy and nutrients to maintain normal temperature and support healthy circulation.
People with very low body weight or inadequate food intake may have less insulating body fat and may struggle to maintain body heat.
Nutritional deficiencies can also contribute to symptoms associated with cold extremities. For example, insufficient iron can cause anaemia, while inadequate vitamin B12 may affect nerve function.
A consistently poor diet, restrictive eating patterns or certain medical conditions that interfere with nutrient absorption may increase the risk.
Eating a balanced diet that includes protein, vegetables, fruits, whole grains and sources of iron and vitamin B12 can support general health.
7. Smoking and Nicotine Use
Smoking can affect blood circulation because nicotine causes blood vessels to narrow. This reduces blood flow to some parts of the body, including the fingers and toes.
Over time, smoking also damages blood vessel walls and increases the risk of cardiovascular disease and peripheral artery disease.
People who smoke may therefore experience cold extremities, particularly when circulation is already impaired.
Quitting smoking can improve overall cardiovascular health and reduce the risk of further blood vessel damage.
8. Certain Medications
Some medications can affect blood circulation or cause blood vessels to narrow, potentially contributing to cold hands and feet.
Examples include certain beta-blockers, some migraine medications and certain decongestants used for nasal congestion.
However, not everyone taking these medicines will experience this side effect, and cold extremities can have other explanations.
If you notice that your hands or feet became unusually cold after starting a medication, speak with your doctor or pharmacist. Do not stop prescribed treatment without medical advice.

When Should You Be Concerned About Cold Hands and Feet?
Cold hands and feet are not always a sign of illness. However, persistent or unexplained symptoms deserve attention, particularly when they occur alongside other changes in the body.
Consider seeing a healthcare professional if:
- Your hands and feet are frequently cold even in warm surroundings.
- You experience persistent numbness, tingling or pain.
- Your fingers or toes regularly change colour.
- You have unexplained tiredness, weakness or dizziness.
- One hand or foot is consistently colder than the other.
- You notice wounds on your feet that heal slowly.
- The symptoms are becoming more frequent or severe.
Seek urgent medical attention if a hand, arm, leg or foot suddenly becomes very cold, pale or blue, especially when accompanied by severe pain, numbness or weakness. These can be signs of an acute circulation problem.
What Can You Do to Improve Circulation and Keep Your Hands and Feet Warm?
The right approach depends on the underlying cause, but some everyday habits may help support circulation and general health.
Stay Physically Active
Regular physical activity encourages blood circulation and supports heart and blood vessel health. Walking, cycling, swimming and other moderate exercises can be beneficial.
Avoid sitting in one position for too long. Taking short movement breaks throughout the day can help.
Eat a Balanced Diet
Include foods that provide iron, vitamin B12, folate and other nutrients needed for healthy blood production and nerve function.
Good sources include beans, fish, eggs, lean meat, dark green leafy vegetables and fortified foods.
Avoid Smoking
Smoking and nicotine can narrow blood vessels and negatively affect circulation. Avoiding tobacco products is an important step towards protecting your blood vessels.
Manage Existing Health Conditions
If you have diabetes, thyroid disease or a known circulation problem, follow your healthcare provider’s treatment plan. Keeping these conditions under control may help prevent complications.
Keep Your Hands and Feet Comfortable
Wear comfortable socks and appropriate footwear. If your hands or feet feel cold, gentle movement and a comfortably warm environment may help.
Avoid applying very hot water or heating devices directly to numb areas, particularly if you have diabetes or reduced sensation, because burns may occur without you noticing.
How Do Doctors Find the Cause of Cold Hands and Feet?
A healthcare professional may ask when the symptoms started, how frequently they occur and whether they affect both sides of the body.
They may also examine your skin colour, temperature, sensation and pulses to assess circulation.
Depending on your symptoms and medical history, investigations may include:
- Full blood count: To check for anaemia.
- Iron studies: To assess iron levels and possible iron deficiency.
- Thyroid function tests: To investigate an underactive thyroid.
- Blood glucose or HbA1c: To check for diabetes or assess blood sugar control.
- Vitamin B12 testing: When nerve symptoms or deficiency are suspected.
- Vascular investigations: Such as an ankle-brachial index or Doppler ultrasound when reduced blood flow is suspected.
Not everyone needs all these tests. The doctor will recommend appropriate investigations based on the findings.
Final Thoughts
Having cold hands and feet even when the weather is warm may seem like a minor inconvenience, but frequent or persistent episodes should not always be ignored.
The symptom may be linked to poor circulation, anaemia, thyroid problems, Raynaud’s phenomenon, diabetes-related nerve damage, nutritional deficiencies, smoking or certain medications.
Although simple lifestyle changes may help, the most important step is identifying the underlying cause. If the cold sensation persists, worsens or occurs alongside pain, numbness, colour changes or unusual tiredness, seek medical advice.
