What are beta-blockers and how can they help with high blood pressure?

ANSWER

Beta-blockers are drugs that block the effects of adrenaline, the hormone that triggers your body's fight-or-flight response when you're stressed. This slows your heart rate and eases up on the force your heart squeezes with. Your blood pressure goes down because your heart isn't working so hard. These medicines can also relax blood vessels so the blood flows better.
