Low blood pressure & Caffeine
Caffeine is a natural stimulant that dramatically increase your blood pressure, alertness, attention and prevent low blood pressure symptoms.
Could Caffeine raise blood pressure?
Caffeine is a natural stimulant found in the nuts, berries, and leaves of certain plants. Stimulants increase the central nervous system activity and make you feel more awake, focused, and alert. Additionally, it causes blood vessel constriction, which may increase blood pressure and alter the supply of blood to the heart.
Caffeine can cause a temporary dramatic increase in blood pressure, it may be due to caffeine ability to block a hormone that widened arteries and additionally it causes the adrenal glands to release more adrenaline,
In normal blood pressure individuals, caffeine may cause a temporary raise in blood pressure, because of its vasoconstrictor (blood vessel narrowing) property. Caffeine does not have any long–term effect on the blood pressure.
Coffee of cardio health
A study published in The American Journal of Clinical Nutrition, 2011 Oct; 94(4):1113-26 titled “The effect of coffee on blood pressure and cardiovascular disease in hypertensive individuals: a systematic review and meta-analysis”. This study observed increase in BP in the first hour after caffeine intake and lasted for ≥3 h.
Many cohort studies found no evidence of an association between habitual coffee consumption and a higher risk of CVD.
Two important studies published in 2007 supported the evidence demonstrates: caffeine-induced blood pressure raise were small and short-lived. Caffeine does not contribute to blood vessel disorders associated with high blood pressure and cardiovascular disease.
Health Benefits of Coffee/Tea
Coffee and tea may have many health benefits. Green tea is most popular as a healthy source of vitamins and antioxidants. Newer research has shown darker beverages like black tea and coffee is a rich source of compounds called polyphenols. This compound may protect against both heart disease and several types of cancer. Recent studies have consistently demonstrated a decreased risk of liver cancer in men who drink coffee.
Polyphenols in coffee and tea have shown to lower the level of activated blood platelets. It may help prevent blood clots; a leading cause for stroke. Polyphenols also lower the body's concentration of C-reactive protein (CRP), an important factor in inflammation. Decreases in CRP have shown to lower the risk of cardiovascular disease, heart attack, and certain types of kidney disease.
