Why Your Hands Feel Cold

Cold hands are something we all experience whether you're digging through the freezer, walking your dog on a chilly morning, or sitting in an over-air-conditioned office. But when your hands feel cold frequently, even when the environment isn’t, it could be more than just a temporary reaction. In some cases, cold hands may point to an underlying health condition that affects circulation or nerve function.

Here’s how to tell when cold hands are normal and when it’s time to seek medical advice.

What Cold Hands Feel Like

The most obvious symptom is skin that feels cold to the touch. However, cold hands can come with other sensations and visible signs, such as:

• Tingling or numbness

• Pain or aching

• Red, pale, or blue-tinted skin

• Swelling

• Blistering (in extreme cold exposure)

These symptoms can vary depending on the cause, and understanding the triggers can help determine whether it’s something temporary or something more serious.

Common Causes of Cold Hands

Several health-related and environmental factors can lead to cold hands. Some are harmless, while others may require medical treatment.

1. Cold Exposure

The most common cause is simple: being in a cold environment. Your body naturally limits blood flow to your extremities to preserve core warmth. Once you're warm again, blood flow returns to normal.

But be cautious: prolonged exposure to freezing temperatures can result in frostbite, a dangerous condition that freezes skin and tissue. Symptoms of frostbite include pale or waxy skin, numbness, and in severe cases, blisters or blackened tissue.

2. Raynaud’s Phenomenon

A frequent medical cause of cold hands is Raynaud’s phenomenon, a condition where blood vessels overreact to cold or stress by narrowing dramatically, restricting blood flow to the fingers and toes.

• Primary Raynaud’s often starts in adolescence and occurs without a known cause. It’s more common in women and can run in families.

• Secondary Raynaud’s is linked to other conditions, such as autoimmune diseases like lupus, scleroderma, or rheumatoid arthritis.

Medications such as beta-blockers, decongestants, antidepressants, and certain chemotherapy drugs can also trigger Raynaud’s attacks.

3. Vascular Disease

Poor blood circulation due to vascular disease can also cause cold hands. This occurs when arteries that supply the hands like the radial and ulnar arteries are narrowed or blocked due to:

• Trauma or injury

• Blood clots

• Aneurysms

• Vessel malformations

• Tumors or vessel wall spasms

In these cases, symptoms may include pain, tingling, discolored fingertips, poor wound healing, and ongoing coldness in the hands.

When Cold Hands Signal Something More

Frequent cold hands, especially if accompanied by color changes, pain, or numbness, may warrant a deeper look.

Warning signs to look out for:

• Pale or bluish fingertips

• Lasting numbness or tingling

• Pain or ulcers on the fingers

• Hands that stay cold even in warm conditions

• A history of autoimmune or vascular disease

Diagnosis: How Providers Identify the Cause

Depending on the symptoms, your healthcare provider may use the following tests:

• Physical exam and medical history

• Cold stress test (measures blood flow before and after cold exposure)

• Blood tests (e.g., ANA test for autoimmune markers)

• Nailfold capillary microscopy to view tiny blood vessels

• Doppler ultrasound to assess blood flow

• Arteriography or MRA to visualize arteries

Treatment Options

Treatment for cold hands varies based on the cause.

For Cold Exposure

• Remove the cold source

• Gently rewarm hands with warm not hot water or blankets

• Avoid high heat on numb areas (it can cause burns)

• In case of frostbite or hypothermia, seek emergency care immediately

For Raynaud’s Phenomenon

While there’s no FDA-approved drug specifically for Raynaud’s, calcium channel blockers (commonly used for blood pressure) can reduce the frequency and severity of attacks.

Lifestyle adjustments also help:

• Wear gloves and layers in cold weather

• Avoid smoking

• Limit caffeine and decongestant use

• Discuss medication alternatives with your provider

For Vascular Issues

Depending on severity, treatments may include:

• Medication to improve blood flow

• Compression garments

• Surgery, in cases of severe blockage or trauma

• Monitoring, if nearby vessels are compensating effectively

Can Medications Cause Cold Hands?

Yes several medications may affect circulation, especially those that constrict blood vessels. These include:

• Beta-blockers (used for heart conditions)

• Antidepressants (SSRIs)

• Stimulants (like Adderall)

• Decongestants

• Chemotherapy drugs

• Appetite suppressants

If your symptoms began after starting a new medication, discuss alternatives with your healthcare provider.

When to See a Healthcare Provider

Seek medical attention if:

• You experience cold hands frequently, especially without a clear environmental cause

• You notice significant color changes in your fingers

• You have an autoimmune or vascular disease

• You experience pain, numbness, or poor wound healing

In emergency cases such as after prolonged exposure to cold or signs of frostbite seek immediate care.
