Raynaud’s Awareness Month: Causes, Symptoms, Diet & How to Manage It

Quick Answer: Raynaud’s is a condition in which the small blood vessels in the fingers and toes narrow too much in response to cold or stress, causing the skin to turn white, blue, or red and feel numb or painful. Raynaud’s awareness helps people recognize the signs and triggers early. There is no cure, but keeping warm, managing stress, staying active, avoiding smoking, and limiting triggers such as caffeine can reduce attacks. See a doctor if symptoms are severe, begin after age 30, or come with joint pain or skin sores.

February is Raynaud’s Awareness Month. Raynaud’s (pronounced ray-nodes) disease is a genuinely painful circulatory problem affecting around 10 million people in the UK. Like many conditions linked to autoimmunity and inflammation, it affects more women than men, and often first appears before age 30.

Raynaud’s Awareness Month aims to raise real visibility for this condition and help people access the support and resources they need to manage their symptoms, and at Eat Burn Sleep we’re proud to help raise that awareness. 

What Are the Symptoms of Raynaud’s?

The classic signs of a Raynaud’s attack are:

• An extreme reaction to cold and temperature changes, causing the small blood vessels in your extremities (fingers, toes, ears, nose, lips, and even nipples) to constrict
• The affected areas turn blue, purple, or white, and feel cold and numb
• Pain or tingling, which can actually worsen as circulation returns

An attack usually lasts from a few minutes to a few hours. Once it subsides and blood flow returns, the affected areas regain their normal color and sensation.

Emotional stress is another genuinely common trigger for these attacks, while caffeine, alcohol, and certain medications can make symptoms worse.

What Causes Raynaud’s Disease?

There are two forms of Raynaud’s:

Primary Raynaud’s (often just called Raynaud’s disease) is the less serious form, affecting the majority of sufferers. Most people with this condition have no other problems associated with it, and can manage their symptoms themselves.

Scientists haven’t yet uncovered the exact cause of primary Raynaud’s. Normally, when your body feels cold, it diverts blood away from the extremities toward your heart and vital organs. With Raynaud’s, this response is heightened, making the blood vessels in your extremities contract faster and tighter than normal. Symptoms can also be triggered by emotional stress, which suggests a real link with the “fight or flight” sympathetic nervous system response.

Secondary Raynaud’s (also known as Raynaud’s syndrome or phenomenon) is caused by another underlying condition. This is usually scleroderma, rheumatoid arthritis, or lupus, inflammatory conditions affecting the connective tissue in your body. Other causes of secondary Raynaud’s include smoking, repetitive vibration injury, and arterial disease.

This secondary form genuinely needs regular, careful monitoring by a healthcare professional, in case of complications like skin ulcers or gangrene.

Primary vs Secondary Raynaud’s: Key Differences

The two forms of Raynaud’s look similar during an attack, but they differ in cause, severity, and how closely they need to be monitored. Here is a quick comparison:

If you are unsure which type you have, a doctor can help work it out. Many people with primary Raynaud’s manage well at home, while secondary Raynaud’s is best managed alongside treatment for the underlying condition.

Is Raynaud’s Hereditary? The Genetic Link

Recent research suggests that genetics may play a role in the development of Raynaud’s phenomenon, although genes alone do not determine whether someone will develop the condition. Scientists (Hartmann et al, 2023) have identified two genetic variants that may influence how blood vessels respond to cold temperatures and stress.

• ADRA2A (Alpha-2A Adrenergic Receptor) gene: This gene helps regulate how blood vessels respond to adrenaline. Certain variations in ADRA2A may cause small blood vessels in the fingers and toes to constrict more strongly than normal, reducing blood flow and increasing the likelihood of Raynaud’s attacks during cold weather or emotional stress.
• IRX1 gene: The IRX1 gene is involved in the development and function of blood vessels. Research suggests that variations in this gene may influence the way small blood vessels contract and relax, potentially contributing to the abnormal circulation seen in people with Raynaud’s phenomenon.

While these findings support a genetic link, genes are only one part of the picture. Environmental factors, cold exposure, stress, smoking, and lifestyle habits can also influence how these genes are expressed and how frequently Raynaud’s symptoms occur.

How to Manage Raynaud’s Disease

While there is currently no cure for Raynaud’s disease, many people can reduce the frequency and severity of attacks by making simple lifestyle changes and avoiding common triggers. Managing cold exposure, reducing stress, and supporting overall circulation are key parts of long-term symptom management.

• Wear warm clothing: Dress in layers and keep your hands, feet, and body warm with gloves, thick socks, scarves, and insulated clothing, especially during cold weather.
• Choose warm drinks: Drinking hot or warm beverages instead of cold ones can help maintain body temperature and may reduce the likelihood of cold-triggered attacks.
• Exercise regularly: Regular physical activity helps improve circulation, supports cardiovascular health, and may reduce the frequency of Raynaud’s episodes over time.
• Practice relaxation techniques: Stress is a common trigger for Raynaud’s attacks. Deep breathing, meditation, mindfulness, and other relaxation techniques can help calm the nervous system and encourage the body’s “rest and repair” response.
• Avoid smoking: Nicotine causes blood vessels to constrict, reducing blood flow and potentially making Raynaud’s symptoms worse.
• Identify and avoid your triggers: Pay attention to situations that trigger attacks, such as cold temperatures, emotional stress, or sudden temperature changes, and take practical steps to minimize exposure.

Although Raynaud’s cannot be cured, combining healthy lifestyle habits with your healthcare provider’s advice can help improve circulation, reduce flare-ups, and make daily life more comfortable.

What Foods Should You Avoid With Raynaud’s?

This is one of the most practical questions I can answer, so let me be direct. Alongside building a proper diet for Raynaud’s disease, it’s just as important to know what to pull back on:

• Caffeine: caffeine and Raynaud’s don’t mix well, since caffeine constricts blood vessels, which can worsen or trigger an attack in sensitive individuals.
• Alcohol: can disrupt circulation and interfere with your body’s temperature regulation.
• Highly processed, inflammatory foods: these add to the underlying inflammation that worsens secondary Raynaud’s specifically
• Very cold foods and drinks: these can act as a direct trigger in the same way cold weather does.

If you’re building out your own Raynaud’s diet to avoid list, start with these, then work with your practitioner on anything more specific to your individual triggers.

What Is the Best Diet for Raynaud’s? Can an Anti-Inflammatory Diet Help?

There is no single proven diet for Raynaud’s. However, an anti-inflammatory, whole-food eating pattern, rich in vegetables, fruit, oily fish, nuts, olive oil, and warming herbs and spices, supports circulation and overall health, and limiting caffeine, alcohol, and processed foods may help reduce triggers.

An anti-inflammatory diet and lifestyle, like the Eat Burn Sleep (EBS) approach, may help support symptom management, especially in secondary Raynaud’s linked to inflammatory conditions. Research suggests that certain foods and nutrients may help manage inflammation in conditions such as rheumatoid arthritis and other autoimmune conditions.

The Bupa Global-approved Eat Burn Sleep program is natural, evidence-based, and used by health professionals with their patients. It is designed to support, not replace, the advice of your doctor.

The Eat Burn Sleep lifestyle is a genuinely holistic approach to care, covering diet, lifestyle, mindset, movement, relaxation, and sleep support. I firmly believe all of these factors are needed together to achieve real, optimum health.

When it comes to a Raynaud’s treatment diet specifically, our recommended foods include warming herbs and spices like ginger, turmeric, cinnamon, nutmeg, and black pepper. They form a key part of the EBS Anti-Inflammatory Food Lists and recipes, and may support circulation while helping to calm inflammation at the same time.

Our library of movement tutorials suits every level of ability, and fits easily into your day no matter how busy you are. Our meditation and mental wellness videos help you relax and build real resilience to the everyday stresses that may trigger your Raynaud’s.

FAQs

Q. What triggers Raynaud’s attacks?

The most common triggers include cold temperatures, emotional stress, and sudden changes in temperature. These triggers cause the small blood vessels in the fingers and toes to narrow, temporarily reducing blood flow and leading to color changes, numbness, and tingling.

Q. Is Raynaud’s disease hereditary?

Research suggests that genetics may play a role in Raynaud’s disease. Recent studies have identified genetic variants, including ADRA2A and IRX1, that may influence blood vessel function. However, environmental factors and lifestyle habits also contribute to how the condition develops and is managed.

Q. Can lifestyle changes help manage Raynaud’s disease?

Yes. While there is no cure for Raynaud’s disease, lifestyle changes can help reduce the frequency and severity of attacks. Keeping warm, exercising regularly, managing stress, avoiding smoking, and following a healthy anti-inflammatory lifestyle may help improve circulation and support overall vascular health.

Q. How long does a Raynaud’s attack last?

An attack usually lasts from a few minutes to a few hours. Warming up gradually and staying calm usually helps color and feeling return sooner.

Q. How do you stop a Raynaud’s attack?

Get somewhere warm, tuck your hands under your armpits or run them under warm (not hot) water, wiggle your fingers and toes, and breathe slowly to settle stress. Avoid very hot water, as numb skin can burn easily.

Q. Is Raynaud’s an autoimmune disease?

Not by itself. Primary Raynaud’s is a circulation problem with no underlying disease. Secondary Raynaud’s is linked to other conditions, often autoimmune or connective tissue conditions such as scleroderma, lupus, or rheumatoid arthritis, so a doctor may check for these.

Q. What is the difference between primary and secondary Raynaud’s?

Primary Raynaud’s has no identifiable underlying cause, is usually milder, and can often be managed with lifestyle changes. Secondary Raynaud’s is caused by another condition, such as scleroderma, lupus, rheumatoid arthritis, smoking, or repetitive vibration injury, and needs regular monitoring by a healthcare professional.

Q. When should you see a doctor about Raynaud’s?

See a doctor if attacks are severe or getting worse, affect only one hand or foot, start after age 30, or come with sores, skin changes, joint pain, or rash. Get urgent help if a finger or toe stays blue or black or shows signs of infection.
