Tea and the Pressure of Blood
New research shows that if you take up drinking tea regularly, you can expect to see your top blood pressure number (systolic) dip by around 2.6 mmHg. Your bottom number (diastolic) will go down by about 2.2 mmHg.
The researchers who discovered this looked at the results of 25 randomized, controlled studies on tea and blood pressure (with a total of 1,476 participants) and concluded that if such improvements happened to everyone with high blood pressure, the stats for related stroke risk would fall by 8 percent, for coronary artery disease mortality by 5 percent, and for all causes of mortality by 4 percent.
Green tea seems to have the most powerful effect on blood pressure; black tea is second; and it makes no difference if it’s caffeinated or decaffeinated.
So how does tea lower your blood pressure? It seems to allow blood vessels to relax and help their lining stay healthy. Although this study didn’t say how much tea to drink, some others indicate that three to four cups a day may be optimal. So, no pressure, tee up a cup!
