If your blood pressure needs monitoring, let your healthcare provider know about any recent caffeine consumption.Check with your healthcare provider about what’s a suitable level of caffeine consumption for you.Caffeine can cause a short-term increase in your blood pressure. ![]() ![]() Although, some research suggests that certain people could be at increased risk from cardiovascular events such as coronary heart disease or stroke because of caffeine consumption. While caffeine consumption can cause a short-term increase in blood pressure, it is not generally thought to increase the risk of hypertension. It is a primary cause of death worldwide and is a risk factor for the development of cardiovascular heart disease, stroke and heart attack. High blood pressure, also known as hypertension, is a consistent increase in pressure that causes the heart to pump harder and damages blood vessels. As mentioned above, a normal blood pressure reading is less than 120/80 mm Hg. The second number is the diastolic pressure, which is the pressure in your arteries when your heart is at rest between beats. The first number is the systolic pressure - the pressure in your arteries when your heart beats. Two numbers are reported when blood pressure is measured. What is high blood pressure or hypertension?īlood pressure is created by the force of blood pushing against artery (blood vessel) walls as it is pumped around the body by the heart. Reviews have also reported changes of between 3-15 mm Hg systolic and 4-13 mm Hg diastolic after caffeine consumption. The results from one study suggest that around five cups per day of coffee caused a 1-2 mm Hg increase in blood pressure. How much does caffeine increase blood pressure?Ī normal blood pressure reading is considered to be less than 120 mm Hg systolic and less than 80 mm Hg diastolic. Blood pressure changes caused by caffeine have been found to last for more than 4 hours. It can take 3-6 hours for caffeine levels to reduce by half in your system. How quickly does caffeine increase blood pressure?īlood pressure is usually affected within 30 minutes of taking caffeine, with the peak effect occurring 1-2 hours after consumption when caffeine levels tend to be at their highest. However, some people will still find that caffeine increases their blood pressure even after long term use. Regular caffeine consumption can lessen the impact caffeine has on your blood pressure as you can build up a tolerance to caffeine. ![]() Blocking adenosine receptors and increasing certain neurotransmitters also causes the short-term elevation in blood pressure that may occur after caffeine is consumed. It blocks the adenosine receptors preventing drowsiness and creates an increase in feelings of happiness, alertness, energy and improves performance. Caffeine can cause a short-term increase in blood pressure (BP) immediately after it’s consumed and for a short time after.Ĭaffeine jolts the central nervous system and brain. It is found commonly in coffee, tea, chocolate, some sodas and energy drinks. Caffeine is one of the most widely consumed natural stimulants worldwide. ![]()
