Key points to remember 💡
Cold urticaria is an allergic skin reaction triggered by exposure to low temperatures, causing red patches, intense itching, and sometimes severe systemic reactions. Relief can be found through medical treatments (antihistamines), avoidance strategies, and appropriate thermal protection with technical heated clothing that maintains a stable body temperature.
Are you familiar with that unpleasant sensation? Those red patches that appear as soon as the cold sets in? Cold urticaria affects 0.05% of the French population—and if you're here, you're probably one of them! Every winter outing becomes a challenge... but we love challenges, and above all, we love helping you overcome them. This allergic reaction can range from simple itching to emergency situations that require immediate treatment.
At G-Heat, we have been supporting people who are sensitive to the cold for seven years. Our thermal expertise has enabled us to develop clothing solutions that provide effective protection against these skin reactions. In this article, you will find out everything you need to know about cold urticaria: how it works, how it can be treated, and above all, how to regain control over this condition.
Understanding cold urticaria to better avoid it
The characteristic symptoms of cold urticaria
Within five minutes of exposure to the cold, it starts! First, you feel intense itching, then red, swollen patches appear on your skin. These symptoms last between 30 minutes and two hours, depending on their intensity.
- Red patches: localized swelling in exposed areas
- Itching: intense and persistent burning sensation
- Swelling: edema of the hands, lips, or throat
How cold triggers an allergic reaction
Contact with cold causes a massive release of histamine. Your immune system reacts as if it were facing a classic allergen. This abnormal reaction turns a simple winter walk into a real ordeal for your body.
The different types of cold urticaria and their specific characteristics
Primary cold urticaria remains the most common type, with no identifiable cause. Secondary urticaria results from an underlying condition such as cryoglobulinemia. The familial form, which is very rare, is genetically transmitted and causes more severe reactions.
Causes and triggers
Critical temperatures and durations of exposure
The trigger temperature varies from person to person, generally between 4°C and 15°C. Sometimes, just two minutes of exposure is enough to trigger an attack. Cold water, icy winds, and even cold drinks can cause reactions.
⚠️ The trap of warming up: what's your natural reflex after exposure to the cold? To warm up quickly! However, this is exactly when your symptoms worsen. The sudden transition from cold to warm intensifies skin reactions.
Everyday situations that trigger attacks
You can trigger an attack by getting out of bed in winter. Excessive air conditioning, swimming in the sea, even holding an ice-cold glass can be enough. These everyday situations become permanent obstacles in your daily life.
- Winter mornings: getting out of bed in a cold room
- Shopping: frozen food and fresh produce
- Outdoor sports: running, cycling in cool weather
Aggravating factors and at-risk populations
Women between the ages of 20 and 40 account for 70% of cases. Stress, fatigue, and certain medications amplify symptoms. People with autoimmune diseases are at increased risk of developing this condition.
Cold urticaria requires constant thermal protection. Our technical clothing maintains a stable body temperature, creating a protective barrier against sudden changes.

The role of humidity and wind in the intensity of reactions
Humidity doubles the intensity of symptoms. Wind accelerates heat loss, triggering attacks more quickly. This combination is the worst-case scenario for sensitive individuals.
Accurately diagnosing cold urticaria
The ice cube test
The doctor applies an ice cube to your forearm for 5 minutes. A positive reaction appears within 10 minutes. This simple test confirms the diagnosis in 90% of cases.
| Exposure Time | Expected Reaction | Diagnosis |
|---|---|---|
| 0–5 minutes | No reaction | Test in progress |
| 5–10 minutes | Red patches | Positive |
| 10+ minutes | No reaction | Negative |
Recommended additional medical tests
Your doctor may order blood tests to rule out other conditions. Testing for cryoglobulins, specific antibodies, and thyroid function completes the diagnosis. These tests help identify any secondary causes.
When should you see a specialist urgently?
Seek immediate medical attention if you experience breathing difficulties or swelling of the face. Signs of anaphylaxis include discomfort, a drop in blood pressure, and loss of consciousness. These symptoms require urgent treatment.
💡 Our expert advice: take photos of your skin reactions as soon as they appear. These images will help your dermatologist make an accurate diagnosis and tailor your treatment.
Differentiating cold urticaria from other skin conditions
Cold urticaria is distinguished by its specific trigger: temperature. Eczema, psoriasis, and chronic urticaria have similar symptoms but persist regardless of cold temperatures. A consultation will help establish the correct diagnosis.
Medical treatments to relieve cold urticaria
Antihistamines: first line of defense
Antihistamines block the action of histamine, which is responsible for the symptoms. Your doctor will usually prescribe cetirizine or loratadine to be taken daily. These medications effectively prevent 80% of mild to moderate attacks.
- Recommended daily preventive dose
- Protective effect after 2 hours
- Few notable side effects
Corticosteroids and emergency treatments
Corticosteroids are used for severe, uncontrolled attacks. Your doctor will prescribe them for a short period of time to avoid side effects. This option is reserved for situations where antihistamines are ineffective.
Epinephrine for severe reactions
An epinephrine auto-injector saves lives during anaphylactic shock. You should always carry one with you if you have a history of severe reactions. After using it, you will need to be hospitalized immediately for monitoring.
New therapeutic approaches and desensitization
Gradual desensitization exposes your body to controlled decreasing temperatures. Omalizumab, a monoclonal antibody, shows promising results in resistant forms. These innovative treatments offer new hope for refractory patients.
Thermal protection accounts for 50% of the strategy against cold urticaria. Our technologies maintain a constant body temperature, drastically reducing exposure to triggering temperature variations.

Daily protection and prevention strategies
Technical clothing designed to maintain body heat
Your anti-crisis dress code? Fabrics that pamper your natural warmth! Modern technical fibers are your dream team: they wick away moisture while carefully retaining your heat. Clever, right? This clothing protection is your first line of defense against skin reactions.
- Base layer: breathable heated underwear
- Mid layer: fleece or down depending on the temperature
- Outer layer: waterproof and breathable windbreaker
Areas of the body to protect first
Your hands, face, and neck remain the most exposed. These areas require extra protection with specific accessories. The head accounts for 40% of body heat loss.
💡 Our expert advice: Invest in high-quality technical gloves. Your hands, which are constantly exposed, are often the first to react. Effective thermal protection can radically change your daily life.
The importance of thermal layers and insulating materials
The multi-layer system traps warm air between each layer. This insulation technique outperforms any single thick garment. Adapting your layers to your activity optimizes your thermal protection.
Adapt your environment to limit exposure
Warm up your car before leaving, set your thermostat to at least 68°F. Avoid excessive air conditioning and drafts. These simple adjustments significantly reduce your daily exposure to the cold.
Managing crises and emergencies
Recognizing the signs of an anaphylactic reaction
Anaphylaxis begins with generalized itching and discomfort. You may experience difficulty breathing, dizziness, or nausea. These symptoms require immediate use of epinephrine.
- Phase 1: widespread itching and redness
- Phase 2: swelling of the face/throat, difficulty breathing
- Phase 3: drop in blood pressure, loss of consciousness
Essential first aid measures
Lie down immediately, raise your legs, and call emergency services. Inject epinephrine into your thigh if prescribed. Stay warm and avoid sudden movements while waiting for help.
Put together a suitable emergency kit
Your kit should contain fast-acting antihistamines, epinephrine, and oral corticosteroids. Add a survival blanket and chemical hand warmers. This preparation can make all the difference during a severe attack.
Inform those around you and prepare an action plan
Explain your condition to your family, friends, and colleagues. Show them how to use the auto-injector in an emergency. A written plan with emergency numbers and procedures will reassure everyone.
