Is it accurate to measure blood pressure after exercise?
I went for a run in the morning and hurried to the hospital for a physical examination. My blood pressure was high when I had it measured. Is it accurate to measure blood pressure right after exercising?
Doctor's answer (1)
Blood pressure measurements taken immediately after exercise are usually inaccurate. This is because physical activity triggers a series of physiological responses, including increased heart rate, accelerated blood circulation, and elevated blood pressure. These responses are normal mechanisms by which the body meets the increased demand for oxygen and nutrients during exercise. Specifically, blood pressure may rise by approximately 20 to 30 mmHg, or about 20% above the baseline level, after exercise.
To obtain the most accurate blood pressure reading, it is recommended to wait approximately 30 minutes to 1 hour after exercise, allowing the body to gradually return to its resting state before taking the measurement. This ensures that the blood pressure reading is closer to the baseline level, thereby better reflecting cardiovascular health.
For individuals with hypertension or those at high risk of cardiovascular disease, regular monitoring of blood pressure changes is necessary to adjust treatment plans accordingly. Additionally, it is important to ensure the body is in a relaxed state before measuring blood pressure, to avoid the influence of tension and anxiety on blood pressure readings.
To obtain accurate blood pressure values, it is advised to avoid measuring blood pressure immediately after physical activity.
