Can Stress Cause Your Blood Pressure to Spike?

Yes, stress can cause your blood pressure to spike temporarily by 20-30 mmHg within minutes. When you experience acute stress, your body releases hormones like adrenaline and cortisol that make your heart beat faster and blood vessels constrict. This fight-or-flight response can raise systolic pressure from a normal 120 mmHg to 150 mmHg or higher during stressful events. Chronic stress may contribute to long-term hypertension by promoting behaviors like poor diet, smoking, and lack of exercise. However, stress-induced spikes typically return to baseline levels once the stressor is removed, unlike sustained hypertension which requires ongoing management.
