Loud DJ music at weddings, festivals and parties may be fun, but it can be risky for people with heart disease or high blood pressure. Prolonged exposure to very loud sound can raise heart rate and blood pressure, increase stress hormones and strain the heart. It can also damage hearing and disturb sleep, which adds to the risk. People with heart conditions or uncontrolled blood pressure should keep a safe distance from speakers, take regular breaks away from the noise and avoid long exposure. Warning signs such as chest discomfort, palpitations, dizziness, severe headache or breathlessness need immediate medical attention. Ear protection and taking prescribed medicines on time can also help.
