2. Brew Decaf Coffee
Even though controversy swirls around the influence of caffeine on blood pressure, reputed medical studies continually connect caffeine with dangerously elevated blood pressure. For instance, researchers from Duke University Medical Center, in Durham, North Carolina, say that 3, 8-ounce cups of java per day will increase an individual’s blood pressure by up to 4-mmhg (or millimeter of mercury), which will keep blood pressure soaring well past bedtime.
The Duke researchers claim that drinking caffeinated beverages—including soda, coffee, and caffeinated teas—magnifies stress response by causing blood vessels to constrict while pumping more blood and increasing heart rate. If you already have elevated blood pressure, caffeine can have a detrimental impact on your heart health.
