New Delhi, Oct 19: While fireworks brighten Diwali nights, experts warn that their deafening noise can darken heart health — particularly for those with pre-existing cardiac conditions. Research from global health institutions, including the National Institutes of Health (NIH), links exposure to high-decibel sounds with an increased risk of heart attacks and cardiovascular diseases.

Studies show that firecrackers can generate noise levels between 130 and 143 decibels — far above the safe limit. A report published by the American College of Cardiology found that people exposed to persistent loud noise had a 72% higher risk of heart attack compared to those in quieter environments.

Medical experts note that sudden loud bursts trigger the body’s stress response, raising blood pressure, accelerating heart rate, and increasing stress hormones — all of which can strain the cardiovascular system.

NIH data also shows that exposure to noise above 55 decibels during the day and 45 decibels at night can raise blood pressure. Prolonged noise exposure has been linked to inflammation and oxidative stress, contributing to heart disease progression.

Vulnerable groups

Those most at risk include individuals with heart disease, hypertension, diabetes, the elderly, and pregnant women. For heart patients, sudden loud sounds may trigger irregular heartbeats or cardiac events.

Warning signs

Chest pain, dizziness, shortness of breath, palpitations, and excessive sweating can signal heart stress and require immediate medical attention.

Preventive tips

Doctors advise limiting exposure to loud sounds, staying indoors during peak hours, closing windows and doors, and using earplugs. Practicing meditation or yoga can also help manage stress. Regular blood pressure monitoring is crucial during festive days.

Experts urge the public to celebrate responsibly. “Community awareness and mindful celebration can help protect vulnerable hearts and ensure that Diwali remains a festival of light — not noise,” a senior cardiologist noted.
