Self-preservation is hard-coded into our bodies and reveals itself in various ways. Your stress response is a series of changes triggered by the brain that prepare your body to face a real or perceived threat. While the body was made to handle these short-term boosts, chronic or long-term stress can have lasting effects on your health.
Fight or Flight
Stress affects all body systems, including the musculoskeletal, respiratory, cardiovascular, endocrine, gastrointestinal, nervous, and reproductive systems. We need to first look into how the brain switches the body into fight-or-flight mode. This mode powers up the body to quickly eliminate the threat or successfully escape it. It starts with the hypothalamus prompting the adrenal glands to release a surge of adrenaline, cortisol, and other hormones. Below is a summary of their functions:
- Adrenaline boosts energy supplies and increases your heart rate and blood pressure.
- Cortisol curbs non-essential functions, increases sugar levels in the blood, and enhances the brain’s use of glucose. Cortisol also alters the immune system response by increasing the availability of substances necessary to repair tissues.
Someone Left the Stress Response On
Though our ancestors faced many more physical harm or death threats, perceived threats are a more common source today. A threat is any situation where the demands exceed our ability or desire to cope. Because each of us bases a threat on our perception, what stresses one person, may not another. Financial issues, family troubles, and heavy workloads are some stressors many individuals face today. These particular examples are not only prevalent; if they do resolve, it can take a while.
When a stressor is always present, the stress response stays on instead of shutting off once the threat is gone. A chronic increase in the heart rate, blood pressure, and glucose levels can lead to numerous complications. Damage to the heart, veins, and arteries in the body are examples of complications from chronic stress and why it can be so widespread and devastating. For instance, every cell in the body relies on a steady supply of oxygen-rich blood and other nutrients to function and live.
When the transport system (veins and arteries) and driving force (heart) that transport the supply are damaged, they cannot nourish the cells in the body effectively. The head-to-toe mental and physical effects include:
- Digestive problems
- Muscle tension and pain
- Heart disease
- Sleep problems
- Increased weight
- Memory and focus impairment
