How do beta blocker heart drugs actually work for anxiety?

Beta-blockers, traditionally used for heart conditions, have found a surprising new role in managing anxiety by blocking adrenaline's effects, which trigger the fight or flight response. This mechanism helps to reduce physical symptoms like rapid heartbeat and trembling, making it easier for people to cope in stressful situations. While primarily a heart medication, their ability to mitigate anxiety's physical symptoms has sparked interest in their broader applications for mental health, highlighting the complex interplay between physical and mental well-being.
