As temperatures surge across Mumbai and nearby regions, Apex Group of Hospitals has reported a noticeable increase in cardiac-related complaints, particularly among high-risk groups. Doctors warn that extreme heat places additional stress on the heart, thereby raising the risk of heart attacks, dehydration, and sudden spikes in blood pressure.
Heatwaves Intensify Health Risks Across India
At the same time, recent data underscores the growing threat of heatwaves in India. According to the India Meteorological Department, 2024 and early 2025 have witnessed longer and more intense heatwave spells across multiple states. Consequently, studies show a steady rise in heat-related illnesses and deaths over the past decade, affecting thousands each year. Urban centres like Mumbai remain especially vulnerable due to high humidity and dense populations. Health experts also highlight a clear connection between rising temperatures and increased hospital admissions for cardiovascular and respiratory conditions.
How Extreme Heat Impacts the Heart
Furthermore, heatwaves lead to excessive sweating and significant fluid loss. This, in turn, reduces blood volume and forces the heart to work harder to maintain circulation. For vulnerable individuals—especially those with pre-existing conditions—this additional strain can quickly become dangerous.
Expert Insights on Emerging Trends
Highlighting these concerns, Dr. Hemant Khemani, Consultant Interventional Cardiologist at Apex Group of Hospitals, explained that the body struggles to regulate temperature during extreme heat. As a result, the cardiovascular system comes under increased pressure. He noted a rise in patients presenting with chest discomfort, palpitations, and uncontrolled blood pressure during this period.
High-Risk Groups Must Stay Vigilant
Moreover, individuals with diabetes and hypertension need to exercise extra caution. Dr. Khemani advised patients with diabetes to monitor blood sugar levels more frequently, as dehydration can cause fluctuations. He also stressed the importance of staying hydrated, avoiding sugary beverages, and maintaining regular meals.
Similarly, individuals with high blood pressure must not skip their medication. Since heat can trigger sudden drops or spikes in blood pressure, routine monitoring becomes essential.
Simple Preventive Measures Can Save Lives
In addition, adopting basic precautions can significantly reduce risks. Experts recommend staying indoors during peak afternoon hours, drinking adequate water even when not thirsty, wearing light clothing, and avoiding strenuous physical activity in extreme heat.
Recognizing Warning Signs Early
Elderly individuals and those with a history of heart disease remain the most vulnerable. Therefore, symptoms such as persistent chest pain, dizziness, breathlessness, or unusual fatigue should never be ignored. Immediate medical attention is crucial in such cases.
Awareness and Early Action Are Key
Ultimately, Apex Group of Hospitals urges citizens to take the ongoing heatwave seriously and act proactively. With timely precautions and increased awareness, individuals can significantly reduce the risk of heat-related cardiac emergencies.
