Coffee Significantly Raises Blood Pressure

Rarely do I drink coffee. Last night, just 1/2 cup of MacDonald's Caramel Macchiato (M size) at about 6.40pm.

At about 8pm (or between 7 & 8pm), systolic blood pressure was 103. At 12.25am, systolic became 132.  In just 4.5 hrs, blood pressure has significantly increased to prehypertension level. 

At both measurement times, diastolic pressure (bottom number) & heart rate no significant difference.

Caffeine constricts not only blood vessels, but also the heart muscle. Very bad. I only wanted it because ALT Pizza coffee was like water (some days back) & made me crave for the taste of Caramel Macchiato.

Bro and I talked about this before. That if a person consistently drinks coffee, it is possible that person will develop high blood pressure without knowing it.

At the moment, the caffeine is making me rather ill.  Because I didn't eat well before the coffee (caffeine irritates the stomach).

Only had 2 boiled eggs at about 11.30am, then went swimming & basketball & drank coconut Mogu Mogu in between. Returning home, I ate 2 oranges & 1 large persimmon. By then it was about 5.30pm. Dinner was at about 6.15pm, too late.  

While my heart rate was 77 at 12.25am, I felt (and am still feeling) rather strange, as if it's beating oddly (that's why I measured it).

In fact, a lot of soft drinks contain caffeine. And these drinks are easily available to kids at the supermarket. Women are always worrying about the sugar content. But actually, it should be the caffeine and phosphoric acid that they should be worrying about. (I don't drink soft drinks/soda, never liked them.).

Not only does caffeine raise blood pressure, it prevents absorption of many minerals & vitamins needed by the body. Example, iron. Very bad for women as many are anemic without knowing it.

Many people including (clueless) doctors underestimate coffee.
