As the temperatures are dipping intensely in Northern parts of India including Delhi NCR and the dense fog is hovering upon the region, cases of cold, flu, and cough are increasing. While occurrence of these seasonal conditions is common, heart diseases also instigate during colder months. Due to the cold nature of the environment, our body works extensively on keeping the insides of it warm causing blood vessels to put additional strain on the heart. For heart patients, colder weathers become challenging as they are more vulnerable to being triggered by heart related issues.
To understand how one can keep themselves and their heart safe in chilly months, the OnlyMyHealth team interacted with Dr T S Kler, Chairman & HOD, BLK-Max Heart & Vascular Institute, Chairman Pan Max, Electrophysiology, Delhi.
The Impact of Cold Weather on the Heart
Dr Kler explains, “Cold waves and foggy conditions can greatly impact individuals with heart conditions. Low temperatures and reduced visibility pose additional risks.” According to the American Heart Association, the cold constricts blood vessels, increasing blood pressure and placing undue stress on the heart. Foggy conditions, meanwhile, carry pollutants that exacerbate respiratory issues, indirectly affecting cardiac health.
To navigate this season safely, heart patients must adopt specific measures to protect their health. Below are five key precautions tailored to minimise risks.
1. Keep Yourself Warm
One of the simplest and most effective precautions is to stay warm. Exposure to low temperatures can constrict blood vessels, elevate blood pressure, and increase the heart’s workload. Dr Kler advises, “Dress in layers and ensure your hands, feet, and head are well-covered. Use hats, gloves, and warm socks to maintain body heat. Avoid prolonged exposure to the cold.” This is particularly important for those who step out early in the morning or late at night when temperatures are at their lowest.

2. Avoid the Coldest Times of the Day
The early hours and late evenings tend to be the coldest parts of the day. For heart patients, venturing out during these periods can be risky. “Plan outdoor activities for mid-morning or early afternoon when temperatures are relatively higher,” recommends Dr Kler. He stresses that avoiding cold exposure during peak fog times also helps reduce respiratory strain caused by pollutants present in fog.
3. Stay Physically Active Indoors
Winter can often discourage outdoor activities, leading to reduced physical activity. However, maintaining circulation is vital for heart health.
Dr Kler suggests, “Engage in light indoor exercises to keep your heart active while avoiding the cold outdoors. Simple activities like stretching or yoga can go a long way in maintaining your overall cardiovascular health.”
4. Keep Track of Your Blood Pressure
Cold weather often leads to elevated blood pressure, which can strain the heart and increase the risk of complications. Regular monitoring is crucial during winter.
“Regularly monitor your blood pressure and consult your doctor if you notice any irregularities,” advises Dr Kler. This precaution ensures timely adjustments to medications or treatment plans as needed.

5. Minimise Fog Exposure
Foggy conditions can worsen respiratory issues, indirectly impacting heart health. The pollutants suspended in the fog pose a particular threat to individuals with pre-existing heart conditions.
Dr Kler recommends, “Use an N95 mask when stepping outside during foggy conditions. The mask helps filter out harmful particles, reducing the strain on your respiratory system and, by extension, your heart.”
Additional Tips for Heart Patients
While the above five precautions address major concerns, Dr Kler outlines additional measures for comprehensive care:
- Stay Hydrated: Winter dehydration increases the risk of blood clots. Warm fluids, such as herbal teas, are a good choice.
- Stick to Your Medication Schedule: Missing doses can aggravate heart conditions. Ensure you follow your prescribed regimen diligently.
- Avoid Smoking and Alcohol: These habits further constrict blood vessels, compounding the effects of cold weather on the heart.
- Be Vigilant for Symptoms: Warning signs such as chest pain, dizziness, or shortness of breath warrant immediate medical attention.
Conclusion
The cold and foggy conditions of winter may pose challenges, but with proper precautions, individuals with heart conditions can navigate the season safely. Dr Kler reiterates, “Heart patients must be proactive in managing their health during winter. Simple steps, such as staying warm, avoiding exposure to fog, and monitoring blood pressure, can make a significant difference.”
By following these guidelines, individuals can reduce their risk and prioritise their well-being during this season. Heart health should always take precedence, no matter the weather.
