Caffeine is a stimulant that increases the activity of the brain and nervous system. This effect manifests itself after 30 minutes – two hours after drinking the drink.
When you drink coffee, caffeine enters your bloodstream. It then interacts with various hormones, brain receptors and neurotransmitters. This causes the arteries and veins to narrow and increases blood pressure.
In addition, caffeine activates the body’s “rhythm or run” reaction. At this time, heart rate increases and blood pressure increases.
Two or three cups of coffee increases systolic blood pressure (upper blood pressure readings) by 3-14 mm Hg. Art and diastolic (lower number) – 4-13 mm Hg. Art. For example, if you usually have a pressure of 120/80, using coffee can increase it to 134/93.
