SAEDNEWS: Coffee, due to its caffeine content, can cause a temporary increase in blood pressure. Caffeine stimulates the nervous system and causes blood vessels to narrow, which leads to a short-term rise in blood pressure. This effect is usually observed between 30 minutes and 2 hours after consuming coffee.

How Does Coffee Affect Blood Pressure?

According to Saednews, Did you know that you and people around the world consume nearly 8.6 billion kilograms of coffee every year? This popular drink is a well-known enemy of drowsiness and helps you feel alert, energetic, and refreshed. When a beverage is consumed so widely and becomes part of your daily routine, it is important to have accurate scientific information about its effects on the body.

Yes, coffee can temporarily increase blood pressure, mainly due to caffeine. This rise usually occurs about 30 minutes to 2 hours after consumption, and in some individuals it can raise blood pressure by around 5 to 10 mmHg.

However, the intensity of this effect depends on several factors:

Caffeine habit: People who drink coffee daily usually experience less increase in blood pressure because their bodies partially adapt to it.
Amount consumed: High intake of coffee or energy drinks has a stronger effect.
Individual sensitivity: Some people are highly sensitive to caffeine.
Existing high blood pressure or heart disease: In these cases, consumption should be more cautious.

Coffee and Blood Pressure

If you want to see whether coffee affects your blood pressure, a simple method is:

  • Measure your blood pressure before drinking coffee.

  • Measure it again 30 to 60 minutes later.

  • If you notice a significant increase, you are likely sensitive to caffeine.

For most healthy people, moderate coffee consumption (about 1 to 3 cups per day) is generally not harmful and has even been associated with certain health benefits in some studies. However, if you have uncontrolled high blood pressure, heart palpitations, anxiety, or insomnia, it is better to limit caffeine intake.
