Why does caffeine raises blood pressure ?

Caffeine raises blood pressure due to its short-lived vasoconstrictive effects.


This means that when caffeine is ingested, the arteries constrict (constrict), and blood pressure rises for some time.


Most people increase their blood pressure within 30 minutes to an hour of consuming caffeinated beverages.


The change in blood pressure is not permanent it is temporary, and it will usually return to normal after 3-4 hours.


When adrenaline is secreted from adrenal gland then the pressure will be raised . The caffeine or caffeinated beverages do the exact thing. Caffeine  excited the adrenal gland . then the adrenal gland starts to secret adrenaline . And as a result the blood pressure is raised .

Adrenaline makes your heart beat faster and constricts your blood vessels, which leads to an increase in blood pressure.


Caffeine and high blood pressure

Although caffeine causes a temporary increase in blood pressure, studies have shown that moderate caffeine intake is safe for high blood pressure and regular consumption of coffee and other caffeinated beverages does not put people at risk of high blood pressure at high risk.

Studies show that drinking 2-4 cups of coffee (200-300mg caffeine) increases systolic blood pressure by 8.1mmHg and diastolic blood pressure by 5.7mmHg on average.


Changes in blood pressure are temporary, and within 3-4 hours everything becomes normal.


Still, if you have a history of high blood pressure or irregular heartbeat, it is wise to keep an eye on your overall caffeine intake.


Possible long-term side effects of caffeine

Taking caffeine in low to moderate doses (1-3 cups of coffee per day) does not appear to have any serious long-term side effects.


However, long-term intake of more than 600 mg of caffeine per day can result in:


  • Anxiety has increased
  • Insomnia
  • Depression
  • Stomach problems

Long-term caffeine intake has been linked to increased fertility in women, urinary incontinence, and hot flashes in men experiencing menopause.


When to stop using caffeine

If you experience any of these symptoms, it may be time to skip your morning coffee - and you may want to skip your lunch cup as well:


  • Anxiety
  • Difficulty sleeping
  • Tremors or muscle tremors
  • Diarrhea, loose stools, and / or incontinence
  • GERD or acid reflux

If you are pregnant, trying to get pregnant, or taking certain medications that may interact with caffeine (including some antibiotics, antidepressants, or asthma medications), it is best to avoid coffee, energy drinks, and other caffeinated beverages.


Caffeine has been linked to increased anxiety levels, so if you have anxiety, reduce your intake of coffee and other caffeinated beverages.


We recommend or suggest that you gradually quit caffeine - with the advice of a doctor or healthcare provider - especially if you have a caffeine-eating habit.


If any coffee drinkers suddenly stop consuming caffeine for a long time, they may experience withdrawal symptoms such as headaches, fatigue and nausea.
