We all experience some sort of anxiety throughout our lifetime; whether it was anxiety of speaking in front of a class or flying on a plane. You start to sweat, your heart races, and you can even feel heavy pressure on your chest. The overwhelming feeling of fear and distress takes over your body and in most cases it's hard to control. But what really happens to our brain when you feel anxious?
With the help of brain imaging technology, scientists discovered that the amygdala and the hippocampus play a role in anxiety and most anxiety disorders. The amygdala relates to fear, memory, and emotion and coordinates these with heart, blood pressure, and other physical responses. It is a structure deep in the brain that can alert the rest of the brain of a threat and trigger a fear or anxiety response. Along with the amygdala, the hippocampus is the part of the brain that encodes threatening events into memories. Both the amygdala and the hippocampus communicate with each other to ultimately initiate a "fight or flight" response.
What I found interesting when researching was that antxiety is not caused by a chemical imbalance in the brain or caused by genes. Rather, biochemical factors such as neurotransmitters contribute to anxiety. Some neurotransmitters targeted in anxiety disorders are gamma aminobutyric acid (sends messages through the nervous system), serotonin (regulates mood), dopamine (control the brains reward and pleasure centers), and epinephrine (also known as adrenaline).
Next time you find yourself in an overwhelming situation, which causes you to have anxiety, just remember there are many natural remedies to overcome it such as simply breathing or even meditation! Life is too short to be worried all the time!
