Napping and Heart Health Risks

What the Research Shows About Napping and Heart Disease

Studies have connected excessive daytime napping to serious heart conditions. NBC reports that long naps correlate with clogged heart arteries, heart attacks, and heart failure. The link also extends to stroke risk and broader cardiovascular disease. People who nap excessively often have underlying health issues that reduce their energy.

Type 2 diabetes, metabolic syndrome, high cholesterol, and high blood pressure accompany frequent napping in many cases. These are all major risk factors for heart disease. Dr. Tahir emphasizes that the napping itself doesn't cause the problem—it signals that something else is already wrong.

The Right Amount of Sleep Protects Your Heart

Getting enough quality sleep is essential for heart health. NBC notes that the American Heart Association recommends seven to nine hours nightly as a key building block for a healthy heart. Most people should get this sleep during nighttime, not spread across daytime naps.

When you do nap, timing matters. The best window is between noon and 2 p.m., according to NBC. A brief, well-timed nap can refresh you without interfering with nighttime sleep or triggering the health concerns linked to excessive daytime rest.
