Why Do I Get a Headache When I Bend Over?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 20th, 2026.
Headaches when bending over typically result from sudden changes in blood pressure or sinus congestion. When you bend forward, blood rushes to your head, temporarily increasing intracranial pressure by 10-15 mmHg. This pressure change can trigger pain receptors in blood vessels and surrounding tissues. Sinus congestion from allergies, colds, or infections creates additional pressure that intensifies when you lean forward. Dehydration, muscle tension in your neck and shoulders, or underlying conditions like high blood pressure can worsen these symptoms. If headaches persist for more than a week or occur with fever, vision changes, or severe neck stiffness, consult a healthcare provider to rule out more serious conditions.
