Does ejaculation raise or lower blood pressure

Blood pressure usually drops briefly after ejaculation, but there are significant individual differences. Excitement of the sympathetic nervous system during ejaculation may lead to a brief increase in blood pressure, but subsequent activation of the parasympathetic nervous system can cause vasodilation and slow heart rate, with most people experiencing a decrease in blood pressure to normal or slightly lower levels. During ejaculation, the human body undergoes complex physiological changes. Excitement of the sympathetic nervous system during orgasm can cause an increase in heart rate and vasoconstriction, which may result in a brief rise of 10-20 mmHg in systolic blood pressure. But this process lasts for a short time, usually returning to normal within 1-2 minutes. After ejaculation, the body releases hormones such as prolactin and oxytocin, which have a sedative effect and can promote vasodilation. At the same time, active substances such as prostaglandin E1 contained in semen may also affect blood pressure by regulating vascular tone. Healthy individuals are more likely to have their blood pressure return to baseline levels within 30 minutes after ejaculation. Some hypertensive patients or individuals at high risk of cardiovascular disease may experience abnormal reactions. People who have not ejaculated for a long time may experience more significant blood pressure fluctuations during their first ejaculation. People taking antihypertensive drugs should pay attention to the time interval between medication and sexual activity to avoid orthostatic hypotension. A small number of patients with autonomic nervous system dysfunction may experience sustained increases or decreases in blood pressure due to abnormal blood pressure regulation. It is recommended to monitor blood pressure changes before and after ejaculation for this population. Regular and moderate sexual activity has a positive effect on blood pressure management. Having sex 1-2 times a week helps maintain vascular elasticity and lower resting blood pressure levels. However, excessive and frequent sexual activity may lead to fatigue and blood pressure fluctuations. It is recommended that hypertensive patients develop personalized plans under the guidance of doctors, pay attention to replenishing water before and after sexual activity, and avoid immediate bathing or vigorous exercise. If there are persistent discomfort symptoms such as dizziness and palpitations after ejaculation, timely medical examination should be sought.
