Our bodies are equipped with a natural mechanism called the “stress response,” also known as the “fight-or-flight” response, which was first described by Walter Cannon at Harvard. When we encounter something that feels like a threat, the amygdala in the brain experiences the emotion fear. The brain then communicates to the hypothalamus, which communicates to the nervous system, which signals to the adrenal glands to release the stress hormones cortisol, adrenaline, and noradrenaline. This assembly-line-like process of the sympathetic nervous system is a crucial part of our body’s internal self-protection mechanism. The only problem is that we are not physiologically designed to be frightened often.
