My husband snores loudly and a friend has told us it’s bad for the heart. Is this true? Gauri Kamat, Bangalore
Yes, loud snoring is a sign of a condition called obstructive sleep apnea - which is a major risk factor for heart disease. Snoring occurs due to severe narrowing of the upper air passage during sleep and this also reduces the amount of oxygen supply to the body. This causes a lot of stress on the heart making the heart pump hard and fast during these episodes at night. There is a high risk of blood pressure, heart attack, irregular heart beat (atrial fibrillation) and stroke if this is not diagnosed and adequately treated.
