In my research paper, I will be studying the correlation between stress and heart disease. The heart is the soul of our bodies, it’s located in the circulatory system and pumps blood around our body as our heart beats. The heart doesn’t only give us life physically; it is the essence of our emotions. 

In our bodies, we have two systems; sympathetic and parasympathetic.The sympathetic nervous system (SNS) releases the hormones (catecholamines – epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. The sympathetic nervous system controls a network of nerves that support the body and activate its “fight or flight response”.The fight or flight response increases when an individual is stressed, in danger or physically active. Fight or flight response connects with not just the brain, but with our hearts. When fight or flight response is put into action the SNS releases two hormones called adrenaline and norepinephrine that tie into acceleration of heart rate and blood pressure. 

Everyday we cross paths with various different types of people; but there is one specific characteristic type that determines the rest of your personality. There are individuals with the characteristic of security leading to calmness and peace. Then, there is the other characteristic that is anxious leading to vulnerability and irrational fear. The group of individuals that are naturally anxious tend to have much higher stress levels than people who are secure. Therefore, this group of people will most likely develop heart problems mildly faster.
