Introduction
Early morning walks are often seen as a healthy habit, especially for people trying to stay active. The calm atmosphere and quiet winter mornings make it even more appealing. However, cardiologists now warn that stepping out for a walk too early during winter may pose serious risks to heart health, particularly for vulnerable individuals.

Why Winter Mornings Can Be Risky for the Heart
According to Dr Tapan Ghose, Senior Director & HOD, Cardiology, Fortis Hospital Vasant Kunj, winter mornings demand extra caution due to a higher risk of heart attacks and strokes. Cold temperatures cause blood vessels to constrict, which raises blood pressure and forces the heart to work harder. This effect is strongest in the early morning hours when both body temperature and environmental temperature are at their lowest.

Impact of Cold on Blood Vessels and Blood Pressure
When blood vessels narrow in response to cold, the heart must pump with more force to maintain circulation. This increased strain can be dangerous, especially for individuals with existing cardiovascular conditions. The sudden exposure to cold after leaving a warm indoor environment can also cause abrupt changes in heart rate and blood pressure, increasing the risk of cardiac events.

Who Is More Vulnerable to These Risks
Dr Ghose highlighted that people with existing heart disease, uncontrolled hypertension, or a history of stroke are particularly at risk. While healthy individuals may adapt better to cold conditions, those with underlying cardiovascular issues may struggle to cope with the sudden physiological stress caused by winter mornings.

Additional Risk Factors: Pollution and Low Oxygen Levels
Apart from cold temperatures, early morning hours often have higher pollution levels and lower oxygen density. These factors further strain the heart and lungs, making early morning walks even riskier during winter, especially in urban areas.

Warning Signs You Should Never Ignore
The cardiologist advised stopping exercise immediately if any of the following symptoms occur:
• Chest discomfort
• Unusual breathlessness
• Dizziness
• Palpitations

These signs may indicate that the heart is under excessive stress and requires immediate medical attention.

How to Make Morning Walks Safer in Winter
Winter walks do not have to be abandoned altogether. Dr Ghose recommends a few safety measures to reduce risks. Start with a gradual warm-up indoors before stepping outside to help the body adjust. Dressing in layers helps maintain body heat and prevents sudden temperature shock. Avoid very early outings when temperatures are at their lowest.

Best Time for Walking During Winter
If possible, shifting your walking schedule can make a big difference. Mid-morning walks are considered much safer as temperatures are milder, oxygen levels improve, and pollution tends to reduce, offering a healthier balance for the heart.

Conclusion
While winter itself is not inherently dangerous, early morning walks during cold weather can increase heart attack risks due to vessel constriction, pollution, and sudden exertion. Being mindful of timing, preparation, and personal health conditions can help you stay active without compromising heart health.
