Beta blockers are medications that treat heart conditions and anxiety by affecting the sympathetic nervous system. They block beta adrenergic receptors, reducing the effects of adrenaline and norepinephrine, which helps manage symptoms like high blood pressure and anxiety. While they can calm physical symptoms, they don't address anxiety's root causes. Beta blockers can also be used for performance enhancement but come with risks, including sleep disruption and potential dangers for asthma patients.
