Chest Pain and Shortness of Breath in Cold Weather: When to Call 112 or Nova Ambulans

Winter months place extra stress on the heart and respiratory system, especially during cold, windy weather. Chest pain and shortness of breath that begin while walking outdoors, climbing stairs, or during sudden temperature changes can range from a mild chill to conditions requiring emergency evaluation, including angina, heart attack, coronary spasm, bronchospasm, and COPD or asthma exacerbations.

Research consistently shows that cardiovascular events increase substantially during winter. [1]Source: American Heart Association (AHA) — American Heart Association[3]Source: European Society of Cardiology (ESC) — escardio.org This guide explains when to call 112, how to make the right triage decision, and what first aid steps to take while waiting for the ambulance.

Why Does Cold Weather Cause Chest Pain and Shortness of Breath?

Cold air triggers the body's defense mechanisms to conserve heat. In some individuals, these responses produce significant symptoms.

Vasoconstriction and Increased Cardiac Workload (Angina/Coronary Spasm)

In cold conditions, blood vessels constrict (vasoconstriction). [1]Source: American Heart Association (AHA) — American Heart Association This can:

Raise blood pressure
Increase the heart's oxygen demand
Trigger angina-like chest pain in those with coronary artery disease [1]Source: American Heart Association (AHA) — American Heart Association[3]Source: European Society of Cardiology (ESC) — escardio.org
In some cases, cause coronary spasm with severe chest pain

For detailed information on heart attack symptoms, see our dedicated guide.

Bronchospasm and Airway Narrowing (Asthma/COPD)

Cold, dry air irritates the airways and can cause bronchospasm (contraction and narrowing of the bronchi) [2]Source: European Respiratory Society (ERS) — ersnet.org, resulting in:

Wheezing
Chest tightness
Shortness of breath
Increased coughing

Asthma and COPD patients experience more frequent flare-ups during winter. Our guide on COPD and asthma attacks in winter covers this topic in detail.

Respiratory Infections and Pneumonia Risk

Viral infections increase in winter. Fever, fatigue, cough, and shortness of breath accompanied by chest pain may signal pneumonia or severe bronchitis.

Excessive Exertion and Sudden Temperature Changes

Leaving a warm home and walking briskly in cold air, shoveling snow, or other intense activities can strain both the heart and lungs, triggering symptoms.

When Is Chest Pain Considered an Emergency?

Chest pain can present as burning, pressure, tightness, heaviness, or stabbing. Cold-weather chest pain should always be taken seriously because it can be the first sign of life-threatening conditions including heart attack.

Important: When in doubt, calling 112 or Nova Ambulans (0216 339 00 39) is always the safest choice. Delayed intervention can cause irreversible damage to the heart muscle.

Emergency Warning Signs: When to Call 112 or Nova Ambulans

If any of the following are present, do not wait -- call 112 or Nova Ambulans (0216 339 00 39):

Chest Pain Red Flags

Chest pain lasting more than 5 minutes, increasing in intensity, or continuing at rest [1]Source: American Heart Association (AHA) — American Heart Association[3]Source: European Society of Cardiology (ESC) — escardio.org
Chest pressure or tightness accompanied by:
- Radiating pain to the left arm, back, jaw, or upper abdomen
- Cold sweating, nausea, or vomiting
- Fainting, extreme weakness, or a sense of impending doom
In someone with known angina or heart disease: pain that is unusually severe or lasts longer than usual
New, unexplained chest pain (especially in people over 40 with hypertension, diabetes, high cholesterol, or a smoking history)

Shortness of Breath Red Flags

Breathing difficulty severe enough to interrupt speech; inability to form complete sentences
Cyanosis (bluish discoloration of lips) or marked pallor [1]Source: American Heart Association (AHA) — American Heart Association
Severe wheezing or a feeling of "I cannot breathe"
Confusion, drowsiness, or agitation
Shortness of breath that worsens rapidly even at rest
In asthma/COPD patients:
- No improvement despite using a rescue inhaler [2]Source: European Respiratory Society (ERS) — ersnet.org
- History of prior ICU admission or intubation for an attack

Situations That May Seem Non-Urgent but Can Be Critical

Chest pain combined with shortness of breath
Chest pain with palpitations and dizziness or near-fainting
Coughing up blood, sudden sharp side pain, and shortness of breath (possible pulmonary embolism)
Any of the above in pregnant women, elderly individuals, or those with serious chronic conditions

112 or Nova Ambulans: Both Handle Emergencies

Triage refers to prioritizing emergency situations. Both 112 and Nova Ambulans operate 24/7 with fully equipped emergency ambulances and professional crews. The key difference is hospital destination, not urgency level.

How to Choose

112: Dispatches the nearest state ambulance and transports to the nearest public hospital.
Nova Ambulans (0216 339 00 39): Provides 24/7 emergency response and transports to the private hospital of your choice.

Both services handle life-threatening emergencies. Choose based on your hospital preference.

When Is a Planned Ambulance Transfer Appropriate?

For situations without acute emergency signs but requiring supervised medical transport:

Post-discharge patient transport from hospital to home
Stable COPD/asthma patients needing controlled transfer
Planned appointments, imaging, or transfers to another facility

First Aid While Waiting for the Ambulance

The following steps represent general first aid guidance. Our until the ambulance arrives guide offers additional detail.

1) Safety and Proper Positioning

Move the person to a warm, well-ventilated area (away from smoke, strong fumes, or stove exhaust).
Loosen tight clothing.
For shortness of breath: A seated position (back supported, leaning slightly forward) is usually most comfortable. [2]Source: European Respiratory Society (ERS) — ersnet.org
For dizziness or fainting tendency: Prevent falls; safely seat or lay them on their side.

2) Stop All Exertion and Provide Reassurance

Do not make them walk or climb stairs.
Panic worsens shortness of breath. Encourage slow, controlled breathing.
Our guide on 5 tips to stay calm in emergencies can help manage anxiety.

3) Provide Accurate Information When Calling 112 or Nova Ambulans

When calling, share concise, clear information:

Full address including floor, apartment, and building name
When symptoms started (e.g., "10 minutes ago while walking in the cold")
Primary symptoms: chest pain, shortness of breath, radiation, cyanosis
Known conditions: heart disease, COPD, asthma; current medications
Allergies, blood thinner use, and whether similar episodes have occurred before

4) Help with the Patient's Own Medications

If the person has their own asthma/COPD rescue inhaler, help them use it according to their prescription.
If they have a physician-prescribed "action plan" (number of puffs, timing), follow it.
Do not administer medications that do not belong to the patient.

Note: For chest pain, giving aspirin at home carries individual risks (bleeding, allergy, alternative diagnoses). The safest approach is to follow guidance from 112 or Nova Ambulans.

5) Maintain Warmth Without Overheating

Use blankets to reduce chilling.
Avoid sudden heat exposure (very hot showers, steam rooms) -- these can strain the circulatory system.

6) Monitor: Consciousness, Breathing, Skin Color

Watch for changes until the ambulance arrives:

Is shortness of breath increasing?
Is there cyanosis?
Is consciousness becoming cloudy?
Is the pain intensity or duration changing?

If the person loses consciousness or stops breathing normally, follow phone guidance from 112 or Nova Ambulans. If you are trained, begin basic life support (CPR).

Conditions Commonly Associated with Cold-Weather Chest Pain

Stable and Unstable Angina

Chest pain that comes on while walking in the cold and eases with rest may be angina. However, if pain lasts longer than usual, occurs at rest, or intensifies, unstable angina or heart attack must be ruled out -- call 112 or Nova Ambulans (0216 339 00 39).

Coronary Spasm

Can cause sudden chest pain even at rest. Cold is a known trigger. [3]Source: European Society of Cardiology (ESC) — escardio.org Requires medical evaluation.

Cold-Induced Bronchospasm

Wheezing and shortness of breath in cold, dry air can occur even in people without a prior asthma diagnosis. If severe, this is an emergency.

COPD Exacerbation

Increased cough, sputum production, and worsening shortness of breath may be triggered by infections or cold exposure. Oxygen levels can drop, requiring careful monitoring.

Risk Groups: Who Should Be Extra Cautious?

The following individuals face higher risk during cold weather:

Those with coronary artery disease, stent, or bypass history
Hypertension, diabetes, high cholesterol, or obesity
Smokers
Asthma and COPD patients
Heart failure patients
Elderly adults
Those experiencing shortness of breath after a recent flu or COVID-19 infection

Winter Protection Tips to Reduce Flare-Ups

Cover your mouth and nose with a scarf before going outdoors to warm the air you breathe. [2]Source: European Respiratory Society (ERS) — ersnet.org
Avoid sudden exertion in the cold (especially early morning hours).
Asthma/COPD patients should not skip their maintenance medications and should carry their action plan.
Ventilate indoor spaces regularly; avoid cigarette smoke.
Stay well-hydrated; seek early medical advice for signs of infection.

Frequently Asked Questions

Q: Is chest pain in cold weather always a heart attack? A: No. Cold-weather chest pain can also be musculoskeletal, gastrointestinal, or respiratory in origin. However, every episode of chest pain should be taken seriously, especially if risk factors are present.

Q: How can I tell the difference between shortness of breath and a panic attack? A: Panic attacks can also cause severe shortness of breath, chest tightness, and a feeling of impending doom. However, assuming "it is just a panic attack" without evaluation is risky. If risk factors exist, calling 112 or Nova Ambulans (0216 339 00 39) is the safest approach.

Q: Should I use my inhaler more frequently in winter? A: Maintenance therapy for asthma/COPD should be continued as your doctor prescribed. If flare-ups increase in cold weather, consult your physician to review your treatment plan.

Q: Is it normal to feel chest tightness every morning in winter? A: Morning hours are already a higher-risk period for cardiovascular events. Recurring morning chest pressure warrants a cardiology evaluation.

Q: My elderly family member complains of shortness of breath in cold weather -- what should I do? A: In elderly individuals, shortness of breath may indicate heart failure, COPD exacerbation, or pneumonia. If the complaint persists or worsens, do not delay medical evaluation.
