Knowledge is power. When you have a deeper understanding of what is happening, it makes the situation more manageable. The same principle applies when it comes to understanding stress and anxiety. My in-depth knowledge of the nervous system, and how it physiologically responds under pressure, was one of the most beneficial tools I used when navigating my healing journey.
Stress is a necessary and unavoidable part of the human experience. In fact, the body is designed to deal with it. Stress is a natural response of a person’s body to certain situations or events. Mild stress can be beneficial as it can help a person stay focused, motivated, and alert. It can also help individuals to perform better in certain situations such as an exam or a presentation. However, chronic and excessive levels of stress can be detrimental to one’s health physically, mentally, and emotionally. Therefore, while some level of stress may be necessary, it is important to manage it effectively to prevent the potential negative effects.
The autonomic nervous system is the part of the nervous system that is responsible for regulating involuntary functions in the body, such as heart rate, breathing, digestion, and blood pressure. It consists of two main branches: the sympathetic nervous system, which prepares the body for action in response to stress, and the parasympathetic nervous system, which regulates the body’s functions during rest and relaxation. The autonomic nervous system works to maintain the body’s internal environment and respond appropriately to changes in the external environment.
When an individual experiences stress, their body activates the sympathetic nervous system, which releases adrenaline and other stress hormones, causing physical changes. These physical changes include an increase in heart rate, blood pressure, and respiration rate, as well as a decrease in digestion.
These physiological changes help prepare the body to tackle the impending threat, be it through fighting or flighting. As a part of the “fight or flight” response, the body also releases cortisol, which can help the body maintain energy over time.
However, when an individual is exposed to chronic stress, such as ongoing work-related stress, anxiety, or a traumatic experience, the body’s continuous activation of the sympathetic nervous system and the release of cortisol can lead to chronic health problems. These health problems may include high blood pressure, gastrointestinal problems, diabetes, heart disease, and depression.
In summary, the body’s response to stress involves the activation of the sympathetic nervous system, which prepares the body to fight or flee from perceived threats. However, chronic stress can lead to prolonged physiological changes, impacting the nervous and other physiological systems leading to long-term health problems.
