Why Strokes Are More Common In The Morning

Key Points:

• Strokes are the fourth leading cause of death and a major cause of disability in the U.S., with over 795,000 cases annually; they occur when a clot blocks blood flow to the brain and are more common in the morning hours between 6 a.m. and 12 p.m.
• Experts explain the morning spike in strokes is due to blood being "stickier," less effective clot-dissolving mechanisms, and a rise in blood pressure upon waking.
• Recognizing stroke symptoms is crucial; the BE FAST acronym helps identify signs such as loss of balance, vision changes, facial droop, arm weakness, and speech difficulties, prompting immediate emergency response.
• Stroke symptoms typically appear suddenly, distinguishing them from gradual nerve issues, and timely medical intervention can reverse damage, especially with treatments like clot-busting medications within 4.5 hours or thrombectomy afterward.
• Preventative measures following the American Heart Association’s Life’s Essential 8—including healthy diet, regular exercise, no tobacco use, adequate sleep, and managing weight, cholesterol, blood sugar, and blood pressure—can reduce stroke risk by up to 80%.
