Cool it on the caffeine
The caffeine that gives coffee, energy drinks, tea, and other foods and drinks their kick can raise blood pressure levels for a brief period of time, Dr. Heller says. “There have also been studies showing these products can improve blood pressure in some people,” he says.
If you have high blood pressure or are concerned about how caffeine affects you, ask your doctor how much you can safely consume each day. (And remember, a cup is just 8 oz—far less than the supersized servings we get at Starbucks and other coffee shops.)
