On a cold morning, many people feel a dull ache or heaviness in the chest and put it down to gas, cold air or a bad night’s sleep. Sometimes it is exactly that. But heart attacks are also more common in winter, and the early warning signs are easy to misread. This guide explains why the cold affects the heart, which symptoms matter most, what to do in the first few minutes, and the habits that lower risk over time.
Emergency first: chest pressure or pain with sweating, breathlessness, or pain spreading to the arm or jaw is a heart emergency until a doctor says otherwise. Call 108 or 112 straight away. Do not wait to see if it passes.
Why winter stresses the heart
Cold air makes blood vessels narrow. This pushes blood pressure up and makes the heart work harder. People also tend to be less active in winter, drink less water and eat richer festive food, which can raise cholesterol, sugar and weight. Doctors in several Indian cities have reported more cardiac emergencies in colder months, especially among people who already have high BP, diabetes or high cholesterol. Winter smog adds further strain, because fine pollution particles inflame the blood vessels. We cover this in detail in why cold weather raises heart attack risk and the winter BP and heart link. For the global picture, see the WHO fact sheet on cardiovascular diseases.
Warning signs: do not wait
Heart attack symptoms are not always dramatic. Watch for:
- Chest pressure, tightness, squeezing or heaviness that lasts more than a few minutes, or comes and goes.
- Pain spreading to the left arm, both arms, the jaw, neck, back or upper stomach.
- Breathlessness with or without chest discomfort.
- Cold sweat, nausea or vomiting, or sudden light-headedness.
- Unusual tiredness over several days, especially in women, diabetics and older adults.
Pain that feels like acidity or gas and does not settle, or that comes with sweating or breathlessness, must be treated as a heart emergency until a doctor says otherwise. Do not wait to see whether it passes. The American Heart Association and the NHS both list these signs. Not sure whether it is the heart or the stomach?

What to do in the first minutes
- Call an ambulance (108 or 112 in India) straight away. Do not drive yourself.
- Sit or lie down in a comfortable position and stay calm.
- Take aspirin only if a doctor has already told you to keep it at home for this purpose. Do not start aspirin on your own if you have bleeding problems or allergies.
- Tell the ambulance team about any medicines you take, and about your diabetes, BP and past heart problems.
- Keep your medicine list and any previous ECG or reports ready.
Who is at higher risk?
- People with high blood pressure, high cholesterol, diabetes or smoking history.
- Men over 40 and women after menopause, though heart disease can strike earlier in Indian adults, especially with a family history.
- People with obesity, a sedentary lifestyle or fatty liver.
- Anyone with chest pain on exertion, breathlessness on walking, or an irregular heartbeat.
If this describes you, speak to your doctor about a check-up, which may include blood pressure, cholesterol and sugar tests, and an ECG. After about 35 years of age, a periodic check-up is sensible for most adults. Our guide on cholesterol, blood pressure and heart attack explains how these numbers connect.
Heart-healthy habits that help
- Keep BP and cholesterol in check with your doctor’s advice and regular tests. Do not stop prescribed medicines because you feel well.
- Walk daily, and warm up gently before any sudden effort on a cold morning.
- Dress warmly, especially the head, chest and hands, and step out of a warm bed slowly.
- Eat more vegetables, dal, whole grains and nuts, and go easy on salt, fried snacks and ghee-heavy sweets.
- Avoid long fasts that leave you dehydrated, and keep drinking water.
- Stop smoking and limit alcohol.
- Manage stress and sleep. Breathing exercises can help, but they do not replace treatment.
Where herbs fit, and where they do not
Some readers look for herbal support for heart health. Ayurvedic texts discuss the heart, or hridaya, in terms of balance and circulation, and some herbs are used traditionally. Flaxseed is a plant source of omega-3 fats and fibre, which are part of a sensible diet. Flax Seed Capsules can be taken as a food supplement; read more in our flaxseed and heart health guide. But there is no good evidence that any herb can prevent or treat a heart attack, open a blocked artery, or replace stents, bypass surgery or prescribed medicines. Never stop or change your heart or BP medicines on the basis of a herbal product.
The bottom line
Heart attacks can strike in winter, and the warning signs are not always obvious. Chest pressure, pain spreading to the arm or jaw, breathlessness and sweating are reasons to call for emergency help without delay. Between emergencies, regular check-ups, daily walking, a balanced diet and taking prescribed medicines on time are the most effective protection. Herbal supplements can be a small part of a healthy diet, but they are not a substitute for medical care.

Frequently asked questions about winter heart attacks
What are the early warning signs of a heart attack in winter?
Chest pressure, tightness or heaviness lasting more than a few minutes, pain spreading to the arm, jaw, neck or back, breathlessness, cold sweat, nausea and unusual tiredness over several days. Call 108 or 112 straight away.
Why do heart attacks increase in cold weather?
Cold air narrows blood vessels, which raises blood pressure and makes the heart work harder. Less activity, less water, richer food and winter smog add further strain, especially in people with high BP, diabetes or high cholesterol.
How can I tell gas pain from a heart attack?
Gas or acidity pain usually eases with a burp or an antacid. If pain does not settle, or comes with sweating, breathlessness or pain in the arm or jaw, treat it as a heart emergency until a doctor says otherwise.
What should I do in the first minutes of a suspected heart attack?
Call an ambulance, sit or lie down and stay calm, take aspirin only if a doctor has already advised it for this purpose, tell the ambulance team about your medicines and conditions, and keep your reports ready. Do not drive yourself.
Can heart attacks happen in young adults?
Yes. Heart disease can strike earlier in Indian adults, especially with a family history, high BP, diabetes, high cholesterol, smoking or obesity. Chest pain on exertion or breathlessness on walking should be checked by a doctor.
Can herbs or flaxseed prevent a heart attack?
No. Flaxseed is a plant source of omega-3 fats and fibre that can be part of a sensible diet, but no herb has been shown to prevent or treat a heart attack or replace prescribed medicines. Never stop your heart or BP medicines because of a herbal product.
