Why do panic attacks happen?
Our bodies have been programmed with an inbuilt system called the fight, flight or freeze response. This response was designed to keep us safe 10,000 years ago where we may have had to fight or run away from danger at a moment’s notice. Alternatively it may have been better to simply stay still - frozen to the spot. The fight, flight or freeze response causes a surge in adrenaline, which is what causes your heart rate to increase and the majority of your physical symptoms.
