How Fear Weakens the Immune System
When we experience fear, our bodies release a surge of adrenaline and cortisone, among other related hormones. However, prolonged exposure to these chemicals can have a detrimental effect on our immune system. As a result, our immune system becomes weaker and less effective in fighting off infections, viruses, and other illnesses. While fear itself may not directly cause illness in most cases, the prolonged state of fear leaves our bodies in a compromised position, making it easier for germs to invade and attack our immune system.
Enhances Survival Instincts
The feeling of fear triggers a primal response in the human body known as the fight or flight response. This instinctive reaction has been passed down through generations, originating from our ancestors who frequently faced the choice of confronting a predator or escaping. When we experience fear, our heart rate increases and blood rushes from our limbs to the core of our body. This redirection allows essential bodily functions to persist while we either flee or engage in combat to preserve our lives. Interestingly, some individuals find the physical sensations associated with this response equally as distressing as the actual threat itself.
