Headaches can be caused by many factors—stress, dehydration, lack of sleep—but did you know that high blood pressure (hypertension) can also trigger severe headaches? A high blood pressure headache feels different from a regular headache and can be a warning sign of a more serious condition, such as hypertensive crisis. "Usually, hypertension does not directly cause symptoms. When blood pressure is very high, it can cause headaches, dizziness, fatigue or visual symptoms," a Harvard report suggests.
