The combination of cold weather and high pollution levels in Delhi can exacerbate cardiovascular risks, especially for individuals with heart disease, diabetes, or hypertension. Symptoms such as chest discomfort, shortness of breath, and fatigue may signal early warning signs of a heart attack. Women may experience subtler symptoms, such as nausea or back pain, which are often overlooked. The strain on the heart during cold mornings and exposure to pollution can lead to serious health emergencies.
