But those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint. Isaiah 40:31 NIV

In Part 1, we reviewed stress by looking at the definition and the types of stress. We learned about the Vagus nerve, that when stimulated or activated, can be helpful in calming down the body. Deep breathing is an effective way to relieve the stress response in the body that can be done anywhere and anytime.

Recalling the definition from the American Institute of Stress (AIS), which is “the non-specific response to the body to any demand for change”, reminds us that stress can be either positive or negative. The stressor is the stimulus (the event, the circumstance, etc.) that calls us into action or puts a demand on the body. Each of us handles stress so differently. Each of us can decide our response and reaction to stressors in our life. If we determine the stressor to be stressful, the body leaps into action. The hypothalamus (found at the base of the brain) is activated. Signals are sent to the pituitary gland and the adrenal medulla (part of the adrenal glands). The body’s “fight or flight” response is activated.

The autonomic nervous system (ANS) helps to maintain homeostasis in the body and includes activities that are performed without conscious effort or control. The ANS house both the sympathetic nervous system (SNS), which is the “fight or flight” response, and the parasympathetic nervous system (PNS), which is the “rest and digest” response. The Vagus nerve that we learned about in Part 1 is part of the PNS.

Initially our body does not know the difference between acute (short term) or chronic (long term) stress. In either case, the “fight or flight” response is activated by the sympathomedullary pathway (SAM). The hypothalamus activates the adrenal medulla to secrete the hormone adrenaline. This sudden stress produces:

• Increase in respiration (lung dilation)
• Increase in heart rate
• Changes in digestion (usually a decrease in appetite)
• Changes in glucose (the liver releases glucose for energy)

Once the threat has diminished, the PNS system brings the body back to homeostasis. If the threat continues to occur or becomes chronic (long term), then the Hypothalamic Pituitary-Adrenal (HPA) system takes over.

In this system, the hypothalamus activates the pituitary gland which secretes the hormone called adrenocorticotropic (ACTH). ACTH stimulates the adrenal glands to produce the hormone called corticosteroid…better known as cortisol. Cortisol enables the body to maintain steady blood sugar levels. Steady blood sugar levels in our bodies help us to cope with prolonged stress. The body’s immunity is compromised and inflammation can occur when blood sugars are unsteady. It becomes clear how long term (chronic) stress can lead to other health concerns.

So how can we change our perception of stress in and on our life? How is it that certain situations or events wreak havoc for one person while motivating others? Cognitive behavior therapy (CBT) might be helpful. CBT is a type of talk therapy that helps bring awareness of negative or inaccurate thinking. This awareness leads to exploring constructive ways to respond more effectively. Usually this is done with help from a therapist or psychotherapist. This is out of my scope of practice, but I feel that it can be very helpful.

Everyone has their story! Family dynamics, past experiences, past trauma situations, and even physical, emotional, and spiritual awareness give each of us a lens to look through. And sometimes talking with an expert can help sort and assess the stress we are feeling. Thus leading to effective solutions and possible ways to cope with everyday stress.

Our health and well being definitely includes our spiritual life. Daily devotional/scripture reading, praying and sitting quietly with God, and meditation using Bible verses can also bring a calm and peace into our life. Psalm 46:10 The Lord invites us in and there is always space available for you at His table. Talking with God can also help us sort and assess the stress we are feeling.

We all have stressors each and every day. We all have felt the effects of stress in and on our life. James, the brother of Jesus, wrote, “Consider it a great joy, my brothers and sisters, whenever you face trials of many kinds, because you know that the testing of your faith produces perseverance. Let perseverance finish its work so that you may be mature and complete, not lacking anything.” James 1:2-3 NIV

• Is the Lord prompting us to make changes?
• Is the Lord wanting us to step out in faith?
• Is the Lord revealing sin in our life?

We can be sure that God will be with us, to guide and comfort us. Psalm 33:20

What is pretty amazing is that our body has systems in place to propel us into action, “fight or flight”, and to bring us back to homeostasis, “rest and digest”. Science is great, but God is greater!
